Cucumbers - one of the most moisture-loving cultures. Without abundant watering, the fruits grow ugly, acquire a bitter taste (about the cucumbers in the greenhouse, follow the link).
Special important to maintain necessary humidity level in closed ground conditions.
It is more convenient to equip big greenhouses automatic drip irrigation systemIn more compact hoses with sprayers and watering cans can be used.
Watering rules
How to water cucumbers in the greenhouse? Secret normal development and a good crop of cucumbers - good moisturizing without stagnant water in the soil. The soil should be light, with enough peat and sand. The substrate must often be loosened, while spudding bushes.
It is advisable to do this after each watering. With this care, the moisture will be distributed perfectly, providing good nutrition plants. The soil around the vines can be ground with peat or straw so that no crust forms on the surface.
It is important to take into account the stage of development of cucumbers. Freshly planted seedlings need moderate moisture; watered at the root, and spray them with a spray bottle.
The growing shoots are watered once in 5-7 days, observing moderation.
The same regime is preserved after the landing of young plants in the greenhouse. Moderate watering continues until flowering begins. A small moisture deficiency is needed. so that actively growing cucumber bushes would not waste their energy on increasing the volume of green mass. Their task is to save strength for planting flower buds and the early formation of ovaries.

If the plants are too richly covered with leaves, it is worth even more to reduce watering, waiting for the topsoil to dry out. In order not to damage the cucumbers, it is necessary to maintain sufficient humidity of the air by pouring water on the floor, glass and greenhouse pipes. After the start of flowering watering increase. Cucumbers water every 2-3 days.
It is important not to pour water under the root, this can cause the stem to rot. Watering is carried out around the plant, and the soil should not be eroded. Ideal option - drop watering, a hose with a spray or a watering can.
In the greenhouse can be equipped with a sprinkler systemsplashing water over the sheet. Abundant watering continues throughout the entire period of fruiting.
It is advisable to combine it with regular spraying or sprinkling. If the leaves of the cucumbers begin to dry out or turn yellow, you can plentifully hose the plant, directing jets of water to the stems and leaves.
Water requirements
Water cucumbers need warm, soft water. It is advisable to defend it in open tanks to remove chlorine. Sometimes tanks are placed directly in the greenhouse for additional moisture.
The ideal water temperature coincides with the air temperature and under no circumstances falls below 20 ° C. Watering with cold water can cause shock., slowing down the development of plants and dropping formed ovaries.
When and how to water?
Watering cucumbers in the greenhouse is preferably carried out in the early morning or in the evening. Hot summer sun should not fall on wet leaves, it can cause a burn.
When the air temperature rises to 25 ° C, irrigation is best done by sprinkling. After abundant watering on the sheet, the doors and window leaves in the greenhouse open wide to accelerate the evaporation of water. Twice a month together with watering spend dressing divorced mullein or bird droppings.
If there are spots on the leaves, sprinkling should be canceled. In this case, carry out watering in the grooves dug in the rows or around the plants. Approximate consumption for flowering or fruiting cucumbers - 30 liters per 1 square. m greenhouses.
Automatic watering options
Automatic drip irrigation systems are installed in all industrial greenhouses. Watering cucumbers in the greenhouse with drip irrigation, suitable and owners of private greenhousesin which 50 and more plants are located.
Advantages of the drip system:
- perfect balance of moisture in the soil, without stagnation of water and drying of the soil;
- water saving;
- the ability to serve the territory of any size without attracting additional labor;
- constant monitoring is not required, automatic systems regulate the flow of water independently;
- there are both expensive imported and affordable domestic systems;
- ease of installation and maintenance;
- system durability;
- when using the soil does not erode, plant roots do not become bare;
- yield increase.
There are several options for drip systems. The simplest means the flow of water by gravity. From a tank installed on a special raised base, water flows through a hose or PVC pipes with holes, moistening the soil.
Water supply is regulated manually, by means of the crane. Such a system is easy to install with your own hands, it will cost inexpensive. It is recommended to first install the tanks and lay out the hoses, and only then plant the seedlings in the greenhouse. It is possible to connect the hoses directly to the water supply. This way there is a significant minus: cold water is not very useful for cucumbers.
Variant of drip irrigation scheme by gravity:
Option wiring drip lines:
More convenient option implies water supply through the pumping station. When the tap is open, a pump connected to a tank, tank or other water source provides automatic distribution of moisture through the pipes.
With drip irrigation water flows very slowlydue to differential pressure, the supply system is periodically turned on and off.
Variants of the drip irrigation scheme through the pump:
Properly configured the construction works smoothly and does not require control. Owners of large greenhouses should think about purchasing a ready-made automatic system.
The kit includes a pump, a pipe system and a timer, which can be programmed for a specific time or the right amount of water. To connect the system need plumbing and access to the mains. On sale there are options for Russian and imported.
By choosing a watering pattern, worth trying out different ways. Their supporters have drip irrigation, sprinkling or moistening through grooves in the ground. Much depends on weather conditions, the size of the greenhouse, varieties of planted cucumbers. By combining techniques, you will surely succeed and get an impressive harvest.
