1, more vents, cooling and cooling. Adjust the temperature, humidity, and carbon dioxide concentration in the shed to expel high temperature, high humidity, and harmful gases as quickly as possible to supplement fresh air.
2, watering, water spray, reduce geothermal storage. In the case of abnormally high heat, timely watering, can make the ground cooling 1 ~ 3 °C, direct spray with fresh water, cooling can be about 1 °C. After watering, wheat straw and straw straw can be covered on the ground.
3, root spray fertilizer. With potassium dihydrogen phosphate. The superphosphate and the wood ash liquid are sprayed on the leaves of vegetables continuously, which is beneficial to humidification and cooling, and can also add water and nutrients. It should be noted that the higher the temperature, the greater the amount of water to be used, and the lower the concentration of spraying.
4. Spray plant growth regulators. Sweet pepper sprayed with 30ppm of chlorophenoxyacetic acid, which has obvious control effect on falling flowers caused by high temperature; tomatoes sprayed 200ppm longer than the solution, can increase the heat resistance of the plant; with 2.4-d dipping or coating, can prevent falling flowers .
In addition, artificial cross-pollination of cross-pollinated vegetables is performed under high-temperature conditions.
