1. Promote facility shading and rain cultivation. In addition to the impact of high temperatures, vegetable production may also be threatened by heavy rain and strong winds. Therefore, we must vigorously promote facilities to avoid rain and shading cultivation, retain the roof film, cover the sunshade net, strengthen the greenhouse facilities, and prevent sudden wind disasters.
2. Assault planting vegetables in the early summer and early autumn. According to the changes in the market, the existing varieties of stubble are used to vigorously develop over-summer and early autumn vegetables. According to the situation of vacancy and autumn deficiency, you can rush to plant 1 or 2 stubble fast-growing vegetables, such as small greens, amaranths, lettuce, greens and white radish. On the basis of early seedlings, plant early cauliflower, early cabbage, early Chinese cabbage, green pepper and other autumn delayed vegetables. Do a good job in raising seedlings of autumn Chinese cabbage, autumn cabbage, autumn lettuce, autumn cauliflower, celery, etc., and ensure transplanting from late August to early September.
3. Strengthen the management of seedbeds and fields. Replenish water in time to cool down and moisturize. Sprinkler irrigation and drip irrigation can be promoted when conditions permit, and artificial irrigation should be conducted in time if conditions are not met. Under high temperature, it is necessary to increase the greenhouse vent. In case of rain or rain, cover the membrane in time to prevent water from entering the shed. Fertilizer water should be replenished in time according to the growth of crops. If possible, use drip irrigation facilities to promote the integration of fertilizer and water. At the same time, do a good job of weeding and weeding to improve the microclimate in the field.
4. Promote green pest control. The low season is a period of high incidence of vegetable diseases and insect pests, and also the period of the most frequent use of pesticides. Vegetable production is difficult. To promote comprehensive prevention and control of pests and diseases, vigorously promote the cultivation of insect nets, give priority to the use of agronomic measures, biological control and physical control methods, promote the integration of green prevention and control and integrated prevention and control technology service model, prevent the abuse of chemical pesticides and the use of prohibited pesticides Turn off the safe use of pesticides.
