Planting vegetables in 24 solar terms in Shaanxi Province
To some extent, watering directly determines the growth, yield and quality of vegetables in summer. High temperature in summer makes soil and plants transpiration water quickly, which is prone to drought, affects the growth of vegetables and easily induces viruses. But improper watering can also lead to physiological diseases. Specific summer watering should pay attention to the following three points:
Never water vegetables at noon in summer 1:
Don't water at noon. Some vegetable farmers think that the temperature is the highest at noon, and watering at this time just cools the vegetables. In fact, watering at noon can easily lead to the phenomenon of "fried" roots after vegetables are stimulated by cold water, which will greatly reduce the yield of vegetables. Therefore, watering before 10 in the morning can not only reduce the temperature, but also do no harm to the roots of vegetables.
Don't water vegetables at noon in summer 2:
Don't flood. Many vegetable farmers think that when the temperature is high in summer, water should be used when watering, and it can reduce the temperature and ensure the water supply of vegetables, which is beneficial to the growth of vegetables. However, as we all know, flooding is easy to make fields accumulate water. Under anaerobic environment, root respiration is inhibited, and root retting, root rot and leaf yellowing are easy to occur, which seriously affects fruit yield and even leads to the death of the whole plant, especially sweet pepper, tomato and other crops that are afraid of waterlogging. Therefore, even in summer, the amount of water should not be too large. In order to avoid water shortage of root system on one side of the big ditch, it is best to irrigate alternately in large and small rows.
