Choose the high temperature resistant and drought-resistant vegetable varieties in the mouth layout, should choose better resistance to heat vegetables, Chinese cabbage, leeks, morning celery, oil and wheat and other leafy vegetable varieties, can also be planted some heat-resistant early radish. According to varieties, timely cultivation of cauliflower, cabbage, tomatoes, pepper, eggplant and other autumn vegetables seedlings.
Application of sunshade net covering technology The high temperature sunshade net has various functions such as blocking light, lowering high temperature, and preventing rainstorm impact. It can effectively improve the growth environment of crops in the summer and autumn and high temperature seasons, and achieve the purpose of stable production increase. The use of shade nets on fast-growing leafy vegetables such as green vegetables, Chinese cabbage, and early celery, can be sown and marketed earlier to increase production. Using shade nets on autumn vegetables, such as cauliflower, cabbage, tomatoes, peppers, and eggplants, can cultivate strong and strong. Commonly used shade nets are black, silver grey, and silver-grey shade nets also have a role in avoiding radon. Coverage covers greenhouses, small sheds and floating surfaces. Flat grass can also play a role in cooling the sun.
Application of micro-droplet micro-injection technology Drought-proof vegetable micro-drop micro-injection technology is an advanced and efficient irrigation technology. In summer and autumn, applying micro-droplet micro-injection technology to vegetable production can effectively reduce the impact of drought on vegetable production and provide disaster-resistant food; save labor, labor, water, and labor intensity; and increase humidity, reduce temperature, and improve the fields. The microclimate regulates soil water, fertilizer, gas, and heat conditions, and promotes the growth of vegetables, so that the commercial nature of leaf vegetables in summer and autumn is greatly improved.
Application of agronomic, physics, and biotechnology technology to prevent pests and agronomics: After the greenhouse vegetables are ordered, the soil should be ploughed in time, exposed to high temperatures or suffocating the greenhouse, and the soil should be filled with water, and lime should be applied. Alternatively, paddy crops, melons, and onions can be used. Rotary rotations and other rotations are used to improve the soil and kill soil-borne diseases and insect pests.
Physical and biological technologies: The comprehensive use of insecticidal lamps, sex attractants, insect nets, azadirachtin and other physical biotechnologies to control high-temperature pests such as Plutella xylostella and Spodoptera litura, improve the control effect of vegetable pests, and ensure the quality and safety of vegetable products.
