Planting techniques of green vegetables

Soil preparation before sowing, destroy the dead branches and rotten leaves left by the previous crop and bury them deeply. Choose vegetable varieties with disease and insect resistance, high quality and high yield, strong stress resistance and good commodity performance. Open field cultivation can be irrigated by plastic film mulching, sprinkler irrigation, drip irrigation and other techniques, reduce the amount of chemical fertilizer as much as possible, use organic fertilizer more, and use chemical pesticides scientifically and reasonably.

1. Soil preparation before sowing, destroy the dead branches and rotten leaves left by the previous crop and bury them deeply. Choose vegetable varieties with disease and insect resistance, high quality and high yield, strong stress resistance and good commodity performance. Nursery pot seedling, substrate seedling, vegetable grafting technology, perfect seedling facilities, improve seedling level, cultivate high-quality seedlings, refine seedlings before transplanting, lay a good foundation for efficient production of pollution-free vegetables.

2. Actively introduce and use new technologies for vegetable production. Carbon dioxide fertilization, irrigation under film, drip irrigation, reflective curtain, sunshade net, new covering materials, substrate cultivation, aphid-proof film, etc. shall be applied for facility planting; plastic film mulching, sprinkler irrigation, drip irrigation and other new technologies shall be adopted for open field cultivation.

3. Strengthen the integrated prevention and control of diseases and insect pests. In the process of prevention and control, agricultural and biological prevention and control methods should be widely applied, chemical pesticides should be used scientifically and reasonably, chemical synthetic pesticides limited to certain limits should be strictly prohibited, chemical pesticides with high efficiency, low toxicity and low residue should be popularized, and the application procedures such as pesticide varieties, dosage, time and frequency should be strictly enforced.
