Can the water be poured in the warm weather?

The vegetable farmer Wang of Zhuangjiazhuang Village, Dongxia Town, Qingzhou City is the first year to plant cucumbers. When the reporter interviewed him in the booth, he happened to meet that he was watering the cucumber. Master Dong not only poured planting lines, but even the operation line was poured, and the ditch was filled with water. He told reporters that now the weather has warmed up, pouring more water, no problem.

The reporter found that, like Wang Shifu, there are not many vegetable growers that increase the amount of water at random as the temperature increases. In fact, this practice is incorrect. Although there is a certain increase in the outside temperature, the ground temperature in the shed is still not stable, blindly, a large number of watering, it is prone to the phenomenon of root damage, increased disease in the shed and so on.

The roots of vegetables require good soil permeability, and excessive watering can easily cause damage to the root system. After watering, the water squeezed away the air in the soil, and the capillary roots could not breathe due to lack of oxygen, and the harmful substances accumulated, the metabolism was blocked, the capillary roots of the vegetables died, and then the dead roots died.

In addition, the temperature of water drawn from the ground is relatively low, generally 10-14 °C, after the water temperature drops, and the greater the amount of water temperature, the greater the decline, the more difficult to recover in a short period of time.

Therefore, although the outside temperature has risen, the amount of watering is still to be controlled when watering, and flooding can not be arbitrarily flooded. In addition, when vegetables suffer from water damage, a variety of ventilation and dehumidification measures should be taken to reduce the soil moisture; on the other hand, the application of leaf fertilizer to supplement the water and nutrients needed for plant growth and development, and reduce the root damage Caused damage. After the land becomes a bit dry, the rooting agent can be used. However, the time is not too early. If the soil is too early, the root will suffocate even more because of the increase of moisture in the soil. The leaves will be yellow and the vegetables will be more difficult to recover.
