Techniques and methods of planting vegetables in open field

Vegetable varieties suitable for local cultivation were selected and soil preparation was carried out. The techniques of nutrient bowl seedling raising, substrate seedling raising and vegetable grafting can be selected, and the stubble should be arranged reasonably during the period. The use of organic and inorganic compound fertilizers, special fertilizers for vegetables, and strengthen the comprehensive prevention and control of diseases and insect pests, rational use of chemical pesticides.

I. varieties of vegetables grown in open field

Common varieties of vegetables planted in open field are chili, cucumber, kale, spinach, radish, tomato, carrot, gourd, Chinese cabbage, Chinese cabbage and so on.

2. Techniques and methods of planting vegetables in open field

1. The soil preparation should be carried out before sowing, and the dead branches and rotten leaves of the previous crops should be burned by fire and buried deeply.

2. Select vegetable varieties with disease and insect resistance, strong stress resistance, high quality and high yield, good commodity performance and suitable for local planting.

3. The techniques of nutrient bowl seedling, substrate seedling and vegetable grafting are selected to further improve the seedling facilities, improve the seedling level, cultivate high quality and strong seedlings, and refine the seedlings before transplanting, so as to lay a good foundation for the efficient production of pollution-free vegetables.

4. it is necessary to adjust and optimize the planting structure, arrange the stubble reasonably, adopt three-dimensional planting and out-of-season cultivation (protected land), 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.

5. it is necessary to actively use new technologies for vegetable production, such as carbon dioxide fertilization, under-film irrigation, drip irrigation, sunshade net, new mulching materials, substrate cultivation, aphid avoidance film and so on. Open field cultivation adopts new techniques such as plastic film mulching, drip irrigation, sprinkler irrigation and so on.

6. it can vigorously popularize the technology of soil fertilization, which is beneficial to reduce the amount of chemical fertilizer, increase the input and use of organic fertilizer, and further establish a scientific and reasonable farming system.

7. Popularizing and applying organic and inorganic compound fertilizers, special fertilizers for vegetables, biological fertilizers, adopting soil testing formula fertilization technology and popularizing formulated fertilizers can reduce the adverse effects of chemical fertilizers on vegetable quality and soil structure.

8. In the process of planting, comprehensive prevention and control of diseases and insect pests should be strengthened, agricultural and biological control methods should be widely used, and chemical pesticides should be used reasonably.

9. Prohibit the use of limited chemical synthetic pesticides, further promote the application of chemical pesticides with low toxicity, high efficiency and low residues, and strictly control the rules for the use of pesticides, such as the dosage, variety, time and times of pesticides.

10. Try to use drugs to control weeds in the primary stage, which can reduce the pollution and residue of pesticides on vegetables, and have a good weeding effect at the same time.

11. When treating the soil with herbicides, the surface layer of the soil should be fine, moist and smooth, which can not only ensure uniform application, but also create good conditions for weed germination and promote the consistent germination of weeds, so that most weeds can be removed at one time.
