How often to water cucumbers in a greenhouse?
Cucumbers are a sun-loving crop that does not respond well to the lack of sufficient moisture. Professional gardeners know that it is not always easy to achieve a good harvest, even in a greenhouse, if you do not observe the temperature regime and do not monitor the humidity level. That is why it is important to provide a quality irrigation system.
General rules
Growing cucumbers in a greenhouse has become popular in all regions of the country, as it allows you to get an early harvest and enjoy fresh vegetables. Only sufficient and regular watering will provide high-quality fruits in large quantities. Not only the volume, but also the temperature of the water plays an important role for plants, so watering should be taken especially responsibly.
Indeed, studies have shown that the use of cold water has a negative effect on the growth of cucumbers: they slow down development and often get sick. The temperature of the irrigation water should be the one to which the soil has warmed up. It is possible to irrigate manually from a tank with settled water, but this takes a lot of time and effort, which is why automatic irrigation systems have recently become in demand.
Speaking about the general rules of watering, it should be noted that the soil in the greenhouse should not dry out, at the same time, the gardener should ensure that it is not waterlogged and ensure high-quality ventilation.In this case, an automatic system with an installed program has a lot of advantages, since it waters in the required amount strictly at a certain time.
Before the appearance of flower ovaries, cucumbers are watered moderately, as this will stop the growth of greenery and direct all forces to the formation of ovaries. As soon as small fruits begin to appear, the number of waterings increases, since this is the only way to give the necessary amount of moisture to form a crop.
Regardless of the type of irrigation system, water cannot be poured directly onto the root system: it can become bare, which will not affect the development of cucumbers for the better. If the root system has opened, it should be immediately covered with earth.
In the greenhouse, there is a greater likelihood of fungal diseases, so the gardener is required to ensure that the top layer of soil is always dried. To do this, a high-quality ventilation system is created, which helps not only to keep the balance of moisture, but also to lower the temperature on days when it becomes unbearably hot.
Experienced summer residents advise watering, with a strong increase in temperature, not cucumber bushes, but their leaves. The method received its name in agricultural technology - sprinkling. It not only lowers the temperature, but also increases the humidity, gives the necessary amount of moisture to the foliage so that it does not burn out inside the greenhouse.
In cloudy weather, there is no need to water the soil too often, it is better to look into the greenhouse more often and monitor the state of soil moisture.On the issue of high-quality irrigation, the gardener will need to moisten the soil regularly in the normalized amount, do not use cold water, monitor the foliage of plants so that it does not sluggish, and do not pour directly onto the root system.
Often, novice gardeners think about when it is worth watering cucumbers in a greenhouse. According to professionals, this should be done either early in the morning, when the sun is not too active, or in the evening after sunset.
in glass
Not every summer resident has modern polycarbonate greenhouses, some still use glass ones. It cannot be said that watering in such a greenhouse has any significant differences, since the same microclimate is created in all greenhouses.
One of the main tasks of the gardener is to monitor the soil: it should not be allowed to be swampy, because the cucumber does not like too much water, as well as overdried soil. If there are deviations, then the ovaries will not produce a crop, but will simply begin to fall off, small cucumbers will deform, the roots will rot or the foliage will fall off. In any case, the summer resident is threatened with a decrease in productivity.
Sharp jumps from severe drought to waterlogging have a bad effect. This is one of the reasons why rot begins to form on the roots. If it is hot outside, it is best to ensure daily watering. For each square meter, 5 to 10 liters of water is required, it all depends on the soil. In the absence of an active sun, this consumption should be halved or watered not every day, but every other day or when the need arises.
It is best to irrigate a glasshouse crop in the evening when the sun is less active and a cool night lies ahead. During the day, ultraviolet penetrates through glass and works like a magnifying glass through water, heating the leaves and soil even more, which adversely affects cucumbers. A prerequisite for obtaining a quality crop is regular ventilation, but there should be no draft in the greenhouse.
It is important to monitor the level of humidity and maintain it, otherwise spider mites may appear in the dry air.
Polycarbonate
Polycarbonate greenhouses are a modern version of a greenhouse that is used in different regions of the country. Not only cucumbers, but also other crops grow remarkably in it, however, timely and plentiful watering plays an important role here too.
As everyone knows, cucumber fruits are mostly water. If you do not give high-quality irrigation, then the flesh inside becomes hollow, bitter. Polycarbonate perfectly retains moisture and heat - this is exactly what the culture needs. Gardeners with extensive experience pay attention to the regularity with which watering should be done on warm days.
This is required from the beginning of the appearance of the sprout and until the last ripening of the fruit, if you want to get a quality crop throughout the entire time. Even if irrigation is carried out through a pressurized hose, it is better not to pour under the root. Many make grooves around the bushes - this is the best option that protects the root system of the plant. Thus, the summer resident not only saturates the bushes with moisture, but also protects them from the appearance of rot.
It is very dangerous to water the plants with cool liquid on cloudy days, as lower temperatures promote the growth of rot and fungal infections.
It is not difficult to learn about moisture deficiency from cucumbers, since the leaves are the first to react. As soon as they fell to the ground, it was time to replenish the moisture in the soil. This can be done by sprinkling or spraying the bushes with water.
Ways
It is not so easy to ensure regular watering, you need to constantly monitor the greenhouse, live nearby or come almost every day, but not every summer resident can afford it. That is why today automatic systems are becoming increasingly popular, when you do not need to water the soil yourself - you just need to install the equipment and set the required mode. To better understand what we are talking about, we will consider separately the two types of irrigation that are available for greenhouses.
Drip irrigation
Drip irrigation systems have been used for decades on an industrial scale, since in large greenhouse complexes it is difficult for a person to independently monitor the condition of the soil. Precisely because installations require some costs, private summer cottages rarely decide on this method of irrigation.
In fact, as studies in the field of agricultural technology have shown, drip irrigation is the best option to give cucumbers the necessary amount of moisture for their normal development. Modern manufacturers began to produce systems designed for small areas at an affordable cost. On average, they can provide water for 50 or more plants. Any gardener can choose an automated system for himself, taking into account the size of the greenhouse and its features.
Among the main advantages that drip irrigation can boast of:
- automated work;
- economical distribution of water;
- ease of installation and ease of management;
- structural durability;
- big choice;
- the ability to organize high-quality irrigation in a greenhouse of any size;
- lack of waterlogging;
- no washing out of the soil under the bushes;
- best fruit quality.
Water can be supplied in such automated systems in different ways:
- by gravity;
- by plumbing.
The summer resident can organize any option himself, if he approaches the work with all responsibility. To make a system with gravity water supply, you need to take a water tank, put it on a stand. This position will create the necessary pressure. A tap is installed on the barrel or canister, which must have a valve and be located at a height of 10 centimeters from the bottom.
A hose is laid under the bushes, which, in turn, is put on a tap. Be sure to make holes in the area that lies on the ground, so that through them water flows under the cucumber bushes. When it is necessary to water, the tap opens and closes when it is required to stop it.
It is impossible to call such a system fully automatic, but the summer resident requires a minimum of effort, which already saves time. It is worth saying that such technological methods of irrigation are very popular with plants, as they respond in response to a high-quality and rich harvest. Automatic irrigation will moisten the soil, even if the owner cannot come to the dacha.
From the pumping station
The hoses laid through the greenhouse for drip irrigation can also be used for irrigation from the pumping station, but in this case you will need to install a pressure regulator. It is he who will be responsible for the amount of fluid supplied. Returning to what has already been said, the water should be warm, that is, not from the water supply, so it is advisable to use a pumping station that will pump liquid from a container where it has already warmed up.
A pumping station is necessary; without it, it will not be possible to provide the necessary pressure. The source can be any large volume container, a filter and a check valve are installed on the unit to ensure stable operation. When the pressure drops, the pump switches on automatically. Since the drip irrigation system slowly supplies liquid under the bushes, you can install the pumping station indoors, as it will turn on and off when necessary, without the participation of the summer resident.
Frequency
Inexperienced summer residents often ask themselves questions about how often watering should be done, whether there are irrigation rules that should be followed. It is worth saying that at different times of the year and in different growing seasons, the irrigation regime will be different.
After planting, you must immediately water, and wait during the flowering period. Despite the fact that cucumbers love water, it is impossible to water too often, otherwise the plants will simply rot.
In summer, when it gets especially hot in the greenhouse, daily watering in the evening is considered the norm. Per square meter, depending on the temperature inside, 5 to 10 liters of water is sufficient. If it is cool outside, then 2 is enough, the main thing is that the earth is not constantly wet.
The appearance of the first flower ovaries signals the cessation of watering for a while.
If done in this way, then the plant will spend its forces not on foliage, but on the development of fruits.
Every summer resident should know that aridity only harms the crop. If you plan to get a rich harvest, then it is worth adding moisture in time and monitoring the soil, which in no case can be covered with cracks or crust.If the plant does not receive water, this will affect not only its general state of development, but also the taste of the fruit. Attention and careful care will help and guarantee a mountain of crispy fruits for a long period.
When forming fruits, it is especially important not to skip watering, otherwise the plant will not have enough moisture to feed the cucumbers with it, as a result, a product will grow that you don’t want to eat. Moreover, the bushes react to the lack of moisture by shedding flowers and ovaries, thus reducing the load.
Recommendations
As already mentioned several times above, it is correct to water the cucumber bushes next to the root system, and not on it, and it is better to do this in the morning or in the evening, but in no case during the day, when the sun is especially active. The norm at a time can be more in the heat and less on cool days.
Before deciding how to irrigate the beds in the greenhouse, it is necessary to put a container where the water will not only settle, but also heat up. Like tomatoes, cucumbers will not tolerate a sharp drop in temperature, even if watered with clean water. Seedlings should also be watered after planting, but with warm water, otherwise it will hurt for a long time.
It is not necessary to fill in the beds until puddles appear, there is a water norm for each square meter, it must be observed if the gardener does not want to face rot and mold.
The best option is to make grooves or furrows around the bushes that protect the root system from being washed away and exposed.
In the summer it gets very hot in the greenhouse, the ventilation system may not be able to cope with the temperature rise, since it is strictly forbidden to create a draft inside the greenhouse for the benefit of cucumber bushes.To improve the situation a little, it is advised to take lime mortar and spray the walls of the greenhouse with it from the outside.
If sprinkling is done, then it is done when the sun is no longer active, otherwise the foliage will get serious burns through the drops. After each irrigation, it is advisable to hill the bushes in order to remove the crust on the soil surface and open access to oxygen for the root system.
The most reliable and safe for the plant was and remains drip irrigation. It allows you to moisten the soil in accordance with the specified regime, so the soil does not dry out, but it is not waterlogged either. Among other things, it saves time.
When the seedlings were just planted in the greenhouse and until the first flowers appeared, the water consumption rate should be 5 liters per square meter. During the appearance of ovaries, the consumption must be increased to 10 liters, but watering should be done at least once every two days.
When fruits appear, irrigation is carried out every other day, and with a strong increase in air temperature every evening. You can use mulching. This method allows the soil to retain moisture longer and provide the plants with the necessary nutrition.
Few people know, but the root system of a cucumber is poorly developed, regardless of whether it grows in an open garden or in a greenhouse. A lot of culture has to spend a lot of energy on the formation of foliage and shoots, which is why on hot days the moisture from the soil is consumed faster.
Watch what happens to the ground under the bushes during watering. As soon as the water stops leaving, then the bed is soaked enough, and it's time to stop irrigation. It is desirable that the liquid gets as little as possible on the base of the stem, as this often causes the development of rot.
As soon as it became noticeable that the amount of greenery on the plant increased, it's time to take a short break, otherwise there will not be a big harvest. The appearance of a large amount of foliage takes a lot of strength and nutrients from the plant for its maintenance, in this case the fruits will not be able to get anything useful for themselves.
You can add pressed yeast to watering, which is a wonderful fertilizer at the time of fruiting bushes. Such organic nutrition not only strengthens the immune system of the culture, but also contributes to the rapid growth and improvement of the taste of the fruit.
In any case, the gardener should remember that without regular and rationed watering, cucumbers in the greenhouse will not develop normally, so it is better to install a drip irrigation system if it is not possible to independently irrigate every day.
