After remedy for cold winds, it must be timely
Recently, during an interview in the greenhouse area of ​​Sunjiaji Street in Shouguang City, the author found that some plants had yellowing and stagnant growth after they were blown by cold wind near the doorway and under the air outlet. Seriously, they had died. . How to deal with greenhouse vegetables after encountering cold winds? First, slow release and slow warming. After the vegetables encounter cold winds, do not rush to let out the wind the next morning, and slowly raise the temperature to the most suitable range for the growth of the vegetables. When the temperature in the booth is too high and the air must be released, be careful not to pull the air outlet too large one at a time. Slowly lower the temperature to prevent it from being damaged if the air outlet vents too quickly. Second, timely use of water temperature adjustment method. After the vegetables are frozen, they should be watered once, because the watering can increase the soil heat capacity, prevent the ground temperature from falling, stabilize the surface atmospheric temperature, and help the temperature rise steadily, so that the frozen tissue can restore its function. The method of artificial water spray can also be used to increase the air humidity in the shed, stabilize the temperature of the shed, and inhibit the evaporation of water from the frozen tissue, so as to promote water absorption and prevent wilting. Again, the plants affected by the cold wind must be properly shaded and sprayed with foliar fertilizer at the appropriate time. After the plants are cold, when the weather is fine, direct exposure to strong sunlight can cause the tissues to quickly lose water, shrink and wilt, and in serious cases, the plants will die. Therefore, it is necessary to shield it, in order to reduce the intensity of sunlight, while avoiding excessive heating. Then the timely and reasonable spray of foliar fertilizer on cold plants can not only improve the nutritional status of the crop, but also increase the concentration of cell tissue fluid, enhance the ability of plants to resist cold and freeze, and promote recovery and growth. Potassium dihydrogen phosphate or chitin can be sprayed 1000 times, the effect is good.
