How to grow a large, fragrant and tasty pumpkin?
Although the birthplace of the pumpkin is Central America, it has been very popular and loved in Russia for a long time. Almost all the inhabitants of the villages, as well as the summer residents in the gardens, you can see a pumpkin that has widely scattered its whips. Its shoots with hard hairs have many broad leaves, strongly branched. The stems have tendrils, spread along the ground, in the presence of a support, they cling and climb along it.
Pumpkin flowers are of different sexes, male and female cells are formed on the same plant. The female flowers have an ovary. Pumpkin flowers are quite large, orange or yellow.
Pumpkin is a dietary product. It is rich in vitamins, minerals, carotene, pectin and dietary fiber.
The necessary conditions
Pumpkin gave its name to a whole family of plants that are well known to everyone. The Cucurbitaceae family includes such vegetable crops as the pumpkin itself, zucchini, squash, zucchini. Melons and watermelons are also representatives of pumpkin. Pumpkin is one of those non-capricious crops that grows in almost all regions of Russia, if you choose the right variety.
This is an annual plant. Its strong root system has a main root that can go into the ground to a depth of 3 m, and long shoots with small roots can take up a space of 4 meters.The length of the gourd stem can reach 7 m or more. Pumpkin fruits form on the main stem at leaf 10 and beyond.
Pumpkin is a light-loving culture. Therefore, when choosing a landing site for it, it is necessary to allocate sunny areas, preferably calm ones. If the pumpkin lacks sunlight, then the number of ovaries decreases, the lashes become very long, and there is a risk of various diseases. From the time of germination until the formation of the first leaves, the pumpkin should receive light for up to 10 hours, which increases the possibility of the formation of female flowers.
This fruit loves heat very much. The optimum temperature at which its seeds germinate is about + 30 degrees, and at a lower temperature it sprouts slowly, at +10 degrees it does not sprout at all. The temperature at which the pumpkin grows and develops well, the stem is covered with wide leaves, and its fruits acquire fragrant, juicy pulp - +25 degrees.
Also a pumpkin and a moisture-loving plant. If she does not receive enough water, then her fruits will not be large. And drought during flowering leads to the fall of flowers and the ovary is not formed.
Pumpkin prefers fertile, humus-rich soil with a good ability to absorb moisture. However, when the soil is oversaturated, excessive growth of shoots and leaves occurs to the detriment of the ovaries. It is pollinated by insects. Her female flower must be pollinated on the first and second day. Unpollinated flowers fall off.
Seed selection and soil preparation
Before sowing pumpkin seeds, you must select a seed variety. The choice largely depends on the climatic conditions of the region. So, in the south, you can cultivate pumpkins of both early and late varieties. For the Urals and Siberia, early ripening varieties are suitable, since the warm period here is not so long.Recommended varieties "Pearl", "Golden bush", "Healing" and others. In the middle lane, you can plant varieties such as Rossiyanka, Candy, Hokkaido, Muscat and Almond.
Seeds for planting must be carefully selected. The largest, densest seeds are suitable for planting, and dry, thin and empty ones are removed. To determine the quality of the seeds, they must be placed in salt water (1 teaspoon per 1 glass of water). Floated seeds are of poor quality, they are thrown away, and the rest, washed with water, dried. Seeds collected from your own crop must first be pickled with a solution of potassium permanganate in order to prevent diseases.
To guarantee seedlings in the garden, it is better to germinate the seeds. Germination continues until white shoots appear from the hatched seeds.
Sprouting is done like this:
- seeds are soaked in water with a temperature not lower than +40 degrees (up to +50 degrees is possible) for three hours;
- then the seeds are placed in a wet natural cloth and placed in heat;
- regularly check the fabric for moisture, preventing it from drying out.
After the seeds have hatched, it is necessary to harden them to increase their resistance to cold. To do this, they still need to be placed in a wet cloth in the cold (for example, in the refrigerator on the bottom shelf) and kept for about five days.
Soil preparation is essential for successfully growing pumpkins and getting a big harvest. It is best to do this in the fall.
Work algorithm:
- Fertilizers must be applied to a selected and well-weeded area: humus - 5 kg, superphosphate - 30 g and potassium chloride - 15 g per 1 sq. m. Instead of humus, it is possible to use manure - 7 kg per 1 sq. m.
- The site is dug to a depth of 20 cm.
- If necessary, white sand (coarse-grained) and peat are added to lighten the soil.
- Add ash, chalk or lime if the soil is acidic.
- Loosen the soil. It is advisable to pour hot water.
It is not necessary to dig up the ground prepared in this way in the fall; in the spring, after removing the weeds, you just need to level the ground with a rake. Two days before planting the pumpkin, the earth is dug up to a depth of 12 cm (approximately half a bayonet), beds are made and ammonium nitrate is added at the rate of 20 g per square meter. m. Such preparation can be carried out in the spring, if the land was not prepared in the fall. To save fertilizer, they can be immediately added to the wells, then well watered, preferably with hot water. The composition of the mixture: 10 g of potash fertilizers and saltpeter, 20 g of superphosphate, a glass of ash per bucket of humus (compost).
Compatibility with other plants
If we take into account the compatibility of vegetable crops during planting, this will increase their yield. Changing crops will not unilaterally deplete the land, so it is recommended to rotate the planting of vegetables according to what nutrients they consume from the soil in order to avoid depleting the land.
When planting pumpkins, it is necessary to take into account such a fact as crop rotation, incompatibility and compatibility of pumpkins with some vegetable plants. Compatible with it are predecessors such as carrots, beets, potatoes, eggplant, onions, peppers, cabbage and legumes.
It is unacceptable to grow pumpkin in the same garden after zucchini, zucchini, squash, cucumbers, as well as melons and watermelons. In addition to soil depletion, the risk of disease and pest damage increases.
Landing
There are several ways to plant a pumpkin. The most popular is planting dry or germinated seeds.This method is applicable in the southern regions and in the middle lane. In this case, the seeds are planted when the threat of frost has passed and the air temperature is above +18 degrees. The soil should warm up to 12-13 degrees Celsius.
Another equally common method is planting pumpkin seedlings. This method is used in the Leningrad, Moscow regions, the Urals and Siberian regions. Seedlings allow you to grow a large crop, eliminate the possibility of death of seeds from the cold during possible frosts. For seedlings, a separate container is used for each plant. It is better to use a small container, approximately 10 by 10 cm in size, which is filled with ordinary seedling soil. When using a plastic container, you need to put sawdust 3 cm thick on the bottom.
The order of work will be as follows:
- Hatched and hardened seeds are sown in a container in two pieces. Weak shoots are later removed.
- They are planted to a depth of 2 cm, then peat is poured. Water before and after planting.
- The first three days, crops are kept at a temperature of +25 - +30 degrees. Seedlings germinate in about 4 days.
- After germination, the sprouts are placed in a cooler place with a temperature of +18 - +25 degrees and kept for one week, then the temperature is again reduced to +15 - +18. This will ensure the growth of strong seedlings and will not allow it to stretch.
- Water the seedlings constantly, but without allowing excess water. Stagnation of moisture is strictly prohibited.
- After two weeks, you need to feed the seedlings with nitrophos (according to the instructions) or a solution of mullein (1 to 10), 100 ml per plant.
Seedlings should have a low, thickened and strong stem, 3 leaves of rich green color.After 21 days, such seedlings are ready for planting in a permanent place in the ground, followed by covering with a film.
There is also such a way as growing pumpkins in a barrel. This method is used in conditions of limited acreage. The stems hang down the barrel without taking up much space on the site. Holes are made in the walls of the barrel and at the bottom so that excess water leaves. The barrel can be painted black to increase its heating.
The barrel is filled with components:
- the bottom layer is organic: branches, large stems, weeds, paper - they rot slowly;
- 2 layer - fallen leaves, tops, grass, humus;
Everything is well packed. The contents of the barrel are first poured with water, and then with an EM preparation, under the influence of which microorganisms are activated and the process of decay begins. In a month, the formation of the soil will be completed.
Another original way to grow pumpkins is in bags. Usually plastic garbage bags are used. First, they can be used to form compost, and then plant a pumpkin in them. After planting the seeds, the bags must be covered either with glass, or with a film, or simply with plastic bottles. This method is convenient in that the bag can be placed anywhere, it is convenient to water it, it retains all the moisture, it saves space on the site.
Process Features
When sowing pumpkin seeds, the following sequence must be followed:
- A bed is formed about 70 cm wide. The interval between the beds is one meter. The distance between the landing holes is from 60 to 80 cm.
- Before sowing seeds, the hole must be warmed up with hot water.
- In warm soil, 2 to 4 seeds can be sown. Planting depth on light soil is 8-10 cm, and on heavy soil - about 6 cm.The seed is sown with the pointed side down.
- The soil is mulched with peat or humus.
- Crops should be covered with plastic wrap. When the sprouts sprout, the polyethylene is cut and the sprouts are released, which subsequently grow. Polyethylene raises the temperature of the ground under the pumpkin by almost five degrees.
For safety net, you can plant both dry and germinated seeds. They are placed at different depths. With the successful growth of germinated seeds, the sprouts of late-germinated dry seeds need to be pinched.
The scheme for planting pumpkins in seedlings is similar to the seed method. After planting, it is advisable to water the seedlings with warm water.
Sprouting time
If the seeds are of high quality or germinated, then after sowing, seedlings appear quite quickly - about four days later. After the appearance of true leaves, the sprouts are thinned out. The number of seedlings left depends on the variety of pumpkin: two sprouts are left for nutmeg pumpkins and hard-barked pumpkins, and one for large-fruited pumpkins.
Care rules
Pumpkin is not as demanding in care as some other vegetable crops, but there are some rules that must be followed when growing it outdoors.
Watering
Watering is the most important factor for pumpkin growth. Having large and wide leaves, it evaporates through them the moisture received from the soil, which adversely affects the development of the root system and stem. It is especially necessary to water it abundantly during flowering and in the process of fruit formation. Pumpkin loves warm water (approximately +20 degrees). Therefore, it is better to water it with settled and sun-warmed water. It is strictly forbidden to use cold water in hot weather. This can lead to the death of culture.
Watering is good to accompany with loosening the earth in the hole at the stem and weeding. Loosening can be done through one time.
top dressing
Large fruits can be grown only when the feeding regimen is observed, which must be carried out often. When the fifth leaf is formed, you need to feed the seedling for the first time after planting. The second feeding is carried out when the lashes appear. Subsequently, they need to be fertilized after 14 days.
For feeding, you can use nitrophoska. The initial dosage for one pumpkin is 10 grams, then it is increased by five grams for each next top dressing. It is acceptable to use both granules and solution. During fruiting, ash is also added to each well (1 glass per plant). Mullein can also be used as a fertilizer.
Topping
Pinching is a method of agricultural technology, which consists in removing the top of the shoot to create conditions for enhanced growth of the side sections of the plant. The positive aspects of pinching are that it provides light and air access to all parts of the plant, and saves space on the site. Purposefully it is necessary to use fertilizers for feeding stems with ovaries in order to increase and accelerate the ripening of the crop, improve the taste of the fruit.
You need to start pinching the pumpkin in July. At this time, the lashes usually have one or two ovaries, about 10 cm in diameter. The whip is pinched approximately 4-6 leaves from the last fruit. The maximum number of fruits depends on the pumpkin variety and the size of the ripened fruits. The larger the fruit, the smaller their number should be on the plant after pinching. All shoots without ovaries are removed.
The formation of a pumpkin bush involves the removal of unnecessary side shoots and extra ovaries, leaving one, two or three stems so that each has no more than three ovaries.
Formation:
- With one whip. After the formation of 2-3 fruits on the main stem, pinching is done 4-5 leaves after the last fruit.
- With two stems. Leave the main stem and one side lash, the strongest. There should be 1-2 ovaries on the main stem, and one on the lateral lash. Pinching is done in the same way for 5 sheets.
- With three stems. Leave the main stem and two side lashes.
Bush pumpkins do not undergo formation, so you do not need to pinch them.
Disease protection
Pumpkin is a culture that is quite resistant to environmental factors. But this does not mean that it is protected from diseases and pests. Phytoinfections pumpkin is rarely sick, as it has immunity to them.
The most common pumpkin diseases:
- bacteriosis characterized by the appearance of dark green spots of irregular shape, which later dry out, crumble. Holes appear in the leaves. Treatment is carried out with a 1% solution of Bordeaux mixture or 0.4% solution of copper oxychloride. If the pumpkin is severely affected by the disease, the plant must be removed.
- Powdery mildew. Signs of this disease are small whitish spots that have a rounded shape, which, growing, cover the entire leaf with a white coating. Leaves dry up. A diseased plant is treated with a solution consisting of colloidal sulfur, at the rate of 20 g of sulfur per 10 liters of water. You can also spray with sodium phosphate in a proportion of 50 g per bucket of water.
- Rotten. With a sharp drop in daily temperatures, rot can occur.Another cause of this disease is watering with cold water. To prevent this, it is necessary to carry out foliar feeding with various micronutrient fertilizers, and water only with warm water. In order to avoid the occurrence of rot on the fruits, it is necessary to prevent the position of the pumpkin on too wet and cold ground; under the fruits, lay litter that does not allow moisture to pass through.
- root rot infects the roots of the plant, which leads to the death of the culture. If the leaves turn yellow at the bottom of the plant, but there is no growth, these are signs of root rot. It is necessary to remove the upper part of the earth near the bush and replace it with healthy soil, at the same time treat the upper green part with ash, coal powder, chalk or lime fluff.
- Yellow mosaic. This disease can be immediately noticed by yellow spots on the leaves. To combat it, "Pharmaiod-3" is used. To prevent yellow mosaic, weed the pumpkin regularly.
In addition to diseases, the pumpkin can be affected by harmful insects. The most common of these are spider mites and aphids. If a pumpkin is damaged by a spider mite, treatment can be carried out with folk remedies. One of them is an infusion of onion peel: pour 200 g of onion peel with boiling water, let stand for 3-4 hours, then add water up to ten liters. In this solution, you can add a little laundry soap, which will give the effect of sticking. An infusion of soap (50 g) and ash (200 g) in water (10 l) helps well against aphids. Spraying with decoctions of celandine and wormwood is also widely used: pour 2-3 kg of chopped grass with a bucket of water, leave for a day. In case of severe damage, they resort to chemical preparations - Trafos, Aktellik and others
No ovary
Sometimes it happens that the green upper part of the pumpkin develops successfully, but the ovaries do not form or are very small and do not grow. To understand the cause and solve this problem, you need to know the characteristics of the biological development of pumpkins, the necessary climate conditions, soil requirements and the rules for caring for the plant.
The reasons
The reasons for the absence of ovaries on a pumpkin are:
- Overly nutritious soil. With an excess of nutrients, the pumpkin directs them to the development of the ground mass, which does not let sunlight and air flow to the ovaries.
- Nutrient deficiencies.
- The shadow also has a detrimental effect on the formation of ovaries: without light, sterile pollen is formed in the pumpkin, and pollination does not occur.
- Non-compliance with watering rules: infrequently in hot weather, often in cool weather.
- Damage to the roots during transplanting seedlings.
- The use of nitrogen fertilizers in cool weather and at ground temperatures below +15 degrees reduces the yield.
- Absence or insufficient number of insect pollinators. If the female flower was not pollinated in the first two days, then there will be no ovaries.
- Poor quality seeds.
If the cause of the absence of ovaries is listed above, then the following measures will help:
- It is recommended to plant a pumpkin in areas where fertilizers have not been applied for a year or two.
- With insufficiently nutritious soil, roots appear on the whips of the pumpkin, which must be sprinkled with earth for better rooting. So the plant has a new additional source of nutrients, and the diet will be restored. The method of growing pumpkins in a barrel or bag, which are filled with soil suitable for the pumpkin, can also help.
- Ensuring sufficient (up to 10 hours) exposure of the pumpkin to the light contributes to the formation of female flowers.
- Watering should be carried out with warm, settled water under the root of the plant, which also increases the formation of ovaries.
- Seedlings should be transplanted very carefully so as not to damage the delicate roots. It is best to grow seedlings in peat pots.
- Nitrogen fertilizers are allowed to be applied only at sufficiently high air and soil temperatures.
- artificial pollination. Under adverse conditions for natural pollination, you need to help the plant by making artificial pollination. Male flowers with removed corollas are applied to the pistils, after removing the bags from the female flowers. You can use a paint brush to transfer the pollen. The next day after pollination, spray the plant with the preparations "Ovary", "Bud", etc. Spraying the green mass of the pumpkin with sweetened water helps to attract insects to the area with plants.
- To eliminate the risk of using low-quality seeds, purchasing several varieties from different manufacturers will help. It is advisable to use seeds adapted to local conditions.
Pumpkin needs space, she does not like cramped areas. If all the sown seeds have sprouted, then it is necessary to remove the weak ones and leave the strongest ones. The yield also depends on the number of shoots - lashes. When pollination is over, be sure to cut off the extra lashes, leaving no more than three with ovaries.
Tips
- The number of female flowers on the pumpkin stem will be greater if the seeds are warmed up before sowing, for example, a bag is placed near the battery for about two months.
- Regular removal of wilted flowers and unformed ovaries can protect the pumpkin from the development of rot and harmful insects.
- To combat powdery mildew, an infusion of mullein, preferably fresh, is an effective remedy. 1 part of mullein and 3 parts of water must be insisted for three days, drained and added water in the amount of 3 liters per liter of mullein solution. Spray the diseased plant.
- To determine if the pumpkin is ripe, you need to examine the leg of the fruit. Dry and hard indicates full ripeness.
- To preserve the crop, a dry room with a constant temperature is required. Suitable underground, pantry.
A pumpkin grown according to all the rules will bring a rich harvest. You can cook a lot of delicious, and most importantly, healthy dishes from it: fresh pumpkin salads, pumpkin juice, stewed pumpkin with rice and millet porridge, and many more others.
