Summer vegetables watering precautions

Water management in summer vegetable production is an important factor that affects the production of vegetables. Summer temperatures are high, soil and plant water transpiration is quick, easy to drought, watering can play a role in supplementing water and reducing temperature, but if improper watering, it will also affect the production of vegetables. Watering vegetables in summer should pay attention to the following points:
1, watering as much as possible with cold water poured into the ground. Summer temperatures are relatively high, plant respiratory intensity, nutrient accumulation, growth is not prosperous, and production is low. In the evening, pouring well water will help reduce the temperature, increase the temperature difference between day and night, reduce the night's respiratory consumption, and is conducive to the accumulation of nutrients.
2, watering should be in the morning and evening, avoid watering at noon. The highest temperature is at noon, and watering at this time can easily lead to the phenomenon of “fried” roots in vegetable roots after being stimulated by cold water, which affects the yield of vegetables. Watering in the morning and evening can not only reduce the temperature but also do no harm to the root system.
3, Do not flood irrigation when watering, do not suddenly dry. Flood irrigation can easily lead to water accumulation in the field. Roots are inhibited from breathing in an oxygen-free environment, and they are easily rotted, thus affecting the yield of vegetables. Therefore, when watering in the summer, the amount of watering should not be too large. In addition, when the vegetable fields dry and damp, solanes, melons and other very easy to cause cracking.
4, the summer high temperature and rain, after the hot rain, timely irrigation with well water, can play a role in cooling.
