Green stalk vegetables have strict requirements on soil selection, requiring fertile or sandy soil, high terrain, convenient irrigation and drainage, rich organic matter and good aggregate structure.
2. Seedling raising and transplanting
Green stalk vegetables can be planted many times a year, cultivated in protected areas in spring and cultivated in open fields in autumn and winter. When raising seedlings, the density should be appropriate to improve ventilation and light transmission. Spraying a new type of high-fat film on seedlings after planting can effectively prevent evaporation and transpiration of aboveground water, isolate pests and diseases, shorten the slow seedling stage, quickly adapt to the new environment and make plants grow healthily.
3. Fertilizer and water management
Because of shallow root distribution, high water consumption, drought tolerance and high nutrient consumption, plants are required to have sufficient fertilizer and water for their growth throughout the growth period. The weather is fine, so it needs to be watered 2-3 times a day to ensure the normal growth of plants; Green stem vegetables are more resistant to rain, but attention should be paid to drainage to prevent soft rot when rain accumulates and avoid water accumulation in the border. The growth of green stem vegetables should maintain sufficient nutrients and carry out necessary topdressing. Fertilization methods are mainly decomposed farmyard manure and Bika granular compound fertilizer.
4. Pest control
Spraying imidacloprid 1000 times solution and emamectin benzoate 1000 times solution to control pests and diseases can effectively control pests and diseases, and applying plant cellular immune factors can improve plant stress resistance and make virus DNA break and apoptosis. Strong immune function, inducing interferon and active cytokines, inhibiting the replication of residual viruses, and promoting the positive energy ecological growth of plants. Based on the disease resistance mechanism of host plants and the principle of pathogen toxicity variation, the reproduction of plant physiological diseases and infectious diseases is controlled.
