First of all, do not water at noon
Some vegetable farmers believe that noon is the hottest time of the day, and watering is the right time to cool down the crops. In fact, watering at noon can easily lead to the phenomenon of "fried" roots after the crop root system is stimulated by cold water, resulting in a significant reduction in yield.
Therefore, it is best to water before 10 o'clock in the morning, which can not only achieve the cooling effect, but also not cause damage to the root system of the crop.
Secondly, the amount of watering should not be too large
Many vegetable farmers believe that the water evaporates quickly in summer, and it does not matter if the water is flooded, so these vegetable farmers often take the practice of watering large ditches and small ditches together in summer, and fill the large and small ditches every time. However, this view and approach is wrong.
Third, we should pay attention to avoiding the special growth period of crops
A certain growth period of crops is not suitable for watering, especially not large watering. For example, during the flowering period of blueberries, watering often causes flowers and fruits to fall; Another example is the ripening period of watermelon, watering is easy to cause cracking.
Therefore, when watering and cooling in summer, vegetable farmers must pay attention to avoiding this special period of crops, so as not to cause adverse effects and losses.
Fourth, pay attention to early nutrition supplementation to prevent viral diseases during the high temperature period
Early nutrition during the high temperature period, the plant is robust and the root system is developed, which will greatly enhance the plant's ability to resist diseases and pests and adversity.
