The summer temperature is high, and the water evaporation of soil and plants is fast. Watering can ensure the moisture of the plants and reduce the soil temperature to create environmental conditions suitable for vegetable growth. However, improper watering will also affect the normal growth of vegetables.
Water management in summer vegetable production process is an important factor affecting vegetable production. Huinong.com recommends that vegetable farmers pay attention to the following three aspects when watering vegetables in summer.
1, avoid watering at noon
Watering time should be carried out in the morning or evening. Avoid watering at noon. Because of the large difference in soil temperature after watering at noon, it is easy to cause physiological damage to the roots of the crop, thus affecting the absorption capacity of water and fertilizer by roots; morning and evening Watering can both lower the temperature without causing damage to the roots.
2, avoid flooding
Watering should not be flooded with large water. It is not suitable for the soil to dry and wet. The flooding of large water is prone to water accumulation in the field, which causes roots to be deficient in oxygen and rotten roots, thus affecting the absorption capacity of the root system and keeping the soil moisture relatively stable.
3, need to hydrate after the rain
Watering after rain: After the rain, the water in the field should be replenished in time to supplement the oxygen in the soil.
