Watermelon flowering, pruning technique
In summer, the growth period of watermelon is in the hot and rainy season, the plant grows rapidly, and the litchi branches are removed or cut off, which is to reduce the nutrient ineffective consumption and balance the reproductive growth and nutrient growth. The method adopted is basically correct. However, if this measure is carried out in heavy rain or high humidity, it should be noted that the disease spreads with the rain and is easily invaded in the wound, causing the plant to become infected. Second, the general farmland is in the suburbs. There are no tall buildings or lightning protection facilities near the field. If the clouds are low, lightning strikes are very likely. Please pay attention to the rainy days in the future. Safety, to avoid lightning strikes, so as not to lose too much. In addition, high temperature and humidity, it is easier to spread the disease. Such as: blight, anthracnose, downy mildew, etc., the bacteria will invade with the rain of the plant with the rain. Therefore, in the rain-free space, it is necessary to take the sterilizing agent 2-3 times. The recommended drug is 500% thiophanate-methyl, 500% carbendazim, or 600 times 70% carbendazim.
