2. All kinds of vegetables planted in the open air. Common vegetable varieties planted in the open field include pepper, cucumber, Chinese cabbage, spinach, radish, tomato, carrot, wax gourd, Chinese cabbage, oil cabbage and so on.
3. Before sowing, prepare the soil, burn the dead branches and rotten leaves left by the previous crop and bury them deeply.
4. Choose vegetable varieties that are resistant to pests and diseases, strong stress resistance, high quality and high yield, good commodity performance and suitable for local cultivation.
5. Choose nutrition bowl seedling, substrate seedling and vegetable grafting technology, further improve seedling facilities, improve seedling level, cultivate high-quality strong seedlings, and harden seedlings before transplanting, so as to lay a good foundation for efficient production of pollution-free vegetables.
6. It is necessary to adjust and optimize the planting structure and arrange the stubble time reasonably. Three-dimensional planting and off-season cultivation (protected land) can be used to realize the diversification of structure and production, and make full use of time, space, soil fertility and seasonal differences to achieve the goal of high quality and high yield.
7. New technologies should be actively applied in vegetable production, such as carbon dioxide fertilization, under-film irrigation, drip irrigation, sunshade net, new covering materials, substrate cultivation, aphid-avoiding film, etc. And new technologies such as plastic film mulching, drip irrigation and sprinkler irrigation are adopted in open field cultivation.
8, can vigorously promote soil fertility technology, is conducive to reducing the amount of chemical fertilizer, increase the input and use of organic fertilizer, and further establish a scientific and reasonable farming system.
9. Popularizing the application of organic and inorganic compound fertilizers, special fertilizers for vegetables and biological fertilizers, adopting soil testing and formula fertilization technology, and popularizing formula fertilizers can reduce the adverse effects of chemical fertilizers on vegetable quality and soil structure.
10. Integrated pest control should be strengthened during planting, agricultural and biological control methods should be widely used, and chemical pesticides should be used rationally.
1 1. It is forbidden to use limited amounts of chemically synthesized pesticides, further promote the application of chemical pesticides with low toxicity, high efficiency and low residue, and strictly control the procedures for pesticide use such as dosage, variety, time and frequency.
12, controlling weeds as much as possible in the early stage can reduce the pollution and residue of pesticides on vegetables and also play a good weeding effect.
13. When using herbicides to treat soil, the surface layer of soil should be fine, moist and smooth, which can not only ensure the uniform application of herbicides, but also create good conditions for the germination of weeds and promote the consistent germination of weeds, so that most weeds can be eliminated by using herbicides once.
