Watershed Cucumber Watering 60% Don't Ignore
Attention to growth
Look at the growth of cucumbers in greenhouses. Usually, when cucumbers in greenhouses are short of water, the leaves will be wilting, the growth will be weakened, and more diseases will occur. At this time, the water should be added in time.
Pay attention to feelings
To see soil moisture, if cucumbers are grown in greenhouses when the soil is not dry, not only is it not conducive to raising the temperature of the soil, but it also easily leads to deterioration of the soil's air permeability, which results in the lack of oxygen in the roots, resulting in rooting and yellow leaves.
Attention to the weather
Before watering, we must watch the weather forecast, choose sunny watering, and ensure that there is 2-3 days of sunny days after watering to avoid rainy weather after watering, which leads to increased humidity in the shed, lower ground temperature, and more diseases. The current season needs more attention. In the first two days after the sunny day, it is not suitable for watering. The temperature of the shed should be raised first to make the cucumber in the greenhouse return to normal and water again.
Pay attention to the temperature
The suitable daily average soil temperature for cucumber growing in greenhouses is about 22°C, and the ground temperature in the shed is usually 15°C-20°C. If the watering is excessive or the watering time is incorrect, the ground temperature will drop rapidly, causing root injury and endangering the plant The growth, therefore, the low-temperature watering is best carried out after pulling the grasshopper in the morning.
Attention to cover film
Covering the film can not only reduce the evaporation of ground water, maintain soil moisture, reduce the number of watering, reduce air humidity, reduce the occurrence of diseases, but also increase the temperature and speed up the growth rate of greenhouse cucumber. Spring greenhouse cucumber watering, generally follow the principle of no shortage of water, rather dry not wet, to maintain greenhouse cucumber soil moisture content of about 60%, to prevent excessive frequent watering, avoid flooding irrigation. Excessive watering tends to lower the temperature in the shed and increase soil temperature, which is detrimental to the growth of vegetables. To take a small water pouring, or point by watering the kettle.
Pay attention to the management after watering
After watering, the temperature was raised to about 40°C at noon the previous two days, and the shed was raised for 1 hour to increase the temperature in the shed. Then increase the ventilation and reduce the humidity in the booth. In response to the easy incidence of cucumber in greenhouses, spraying prevention to reduce the occurrence of pests and diseases.
