Summer management of vegetables to a certain extent, watering directly determines the growth of vegetables, yield and quality. In summer, the temperature is high, the soil and plants are transpiration and moisture are fast, and it is prone to drought, which affects the growth of vegetables and induces viruses easily. However, improper watering can also lead to the occurrence of physiological diseases. Specific watering in summer should pay attention to the following three points:
Do not dry and damp. Solanum, melon vegetables, the results of the period, suddenly dry Hu Hu easily cracked fruit. This is due to the lack of water in the soil when the expansion of the fruit is inhibited, once the watering too much, the fruit quickly absorb water, speed of fruit expansion, especially the pulp part of the large amount of water absorption, the skin growth rate is relatively slow, so it is prone to cracking, This phenomenon is particularly evident in tomato and melon crops.
Do not water at noon. Watering at noon can easily lead to the phenomenon of “fried†roots in vegetable roots when they are stimulated by cold water, resulting in a significant reduction in vegetable production. Therefore, before 10:00 in the morning, it can not only achieve the cooling effect, but also does not cause damage to the vegetable roots.
Do not flood. Many vegetable farmers believe that the summer temperatures are high. When watering, flooding should be used to flood the area. Large and small rows are poured together. This can reduce the temperature and the ground temperature and ensure the moisture supply of vegetables. It is conducive to the growth of vegetables. However, flooding and flooding are easy to accumulate in the fields. water. Roots are restrained from breathing in an anaerobic environment. They are prone to picking up roots, rotting roots, and turning yellow leaves, seriously affecting fruit yield, and even causing the death of whole plants. This is especially true for sweet peppers and tomatoes. So, even in the summer, the amount of watering should not be excessive. In order to avoid the lack of water in the roots on the side of the big ditch, it is best to alternately pour in large and small rows.
