As the temperature rises, the night temperature in the shed is also greatly increased. At this time, improper management of shed vegetables can cause problems such as falling of flowers, fruit drop, yellow leaves, and premature senescence. The author proposes that the current vegetable management should be done as follows: : 1. Foliar spray fertilizer: In addition to anti-high temperature, but also timely foliar spray boron calcium fertilizer, in order to promote flowering fruit set, anti-umbilical rot and other physiological diseases. 2. To prevent leggy: As the temperature gradually increases, the temperature difference between day and night becomes smaller, vegetable plants are prone to leggy, especially solanaceous vegetables and melon vegetables. Once the plant is long, it will certainly result in falling flowers and fruit. Even if the fruit is sitting, it is prone to empty fruit and malformed fruit. To prevent leggy, we must first pay attention to the temperature difference between day and night; second, the amount of nitrogen fertilizer should not be too large, try to increase the application of phosphorus and potassium fertilizers, promote fruit setting, if necessary, spray tomato, sweet pepper "overwhelming" 3,000 times or "helping prime 750-fold control, melons and vegetables can be sprayed with 750-times booster or 1500-times booster. 3. Sunburn prevention: After the end of April each year, the temperature is high and the light is strong. Vegetables are prone to sunburn and other high temperature disorders. It is recommended that leaf picking in vegetable management not be excessive once. 4. Anti-hormone poisoning: When the temperature rises, when the vegetables are used for flowering or picking melons, the concentration of the anthers should be reduced accordingly, and the principle of using the hormone concentration off-line at high temperatures should be followed.
