Planting technique of green stem vegetable

Choose fertile soil with convenient drainage and irrigation, rich in organic matter and good aggregate structure. It can be planted many times a year, protected cultivation in spring and open field cultivation in autumn and winter. The weather is sunny, need to be drenched in water 2-3 times a day, green stem vegetables to maintain adequate nutrients in the growth, the necessary topdressing. Spraying leaves with 1000 times solution of imidacloprid can effectively control diseases and insect pests.

1. Soil selection

Green stem vegetable is strict in soil selection, and it is suitable for fertile soil or sandy soil with high topography, convenient drainage and irrigation, rich organic matter and good aggregate structure.

two。 Seedling raising and transplanting

Green stem vegetables can be planted many times a year, protected cultivation in spring and open field cultivation in autumn and winter. When raising seedlings, it is necessary to have proper density and improve ventilation and light transmittance. Spraying new high-fat film on seedling body after seedling planting can effectively prevent aboveground water from evaporation, seedling water non-transpiration, isolate diseases and insect pests, shorten slow seedling period, quickly adapt to the new environment, and make plants grow healthily.

3. Fertilizer and water management

Due to the shallow root distribution, high water consumption, drought tolerance and high nutrient consumption, sufficient fertilizer and water are required to supply the plant growth during the whole growing period. The weather is sunny, need to shower 2-3 times a day to ensure the normal growth of plants; green stem vegetables are more resistant to Rain Water, but Rain Water over-accumulation pay attention to drainage, pay attention to the prevention and control of soft rot, so as to avoid no stagnant water on the border surface. Green stem vegetable growth to maintain sufficient nutrients, the necessary topdressing, fertilization to mature farm manure, compound fertilizer, fertilization combined with new high-fat film to increase fertilizer efficiency.

4. Pest control

Spraying 1000-fold solution of imidacloprid and 1000-fold solution of carbaryl salt on the leaf surface can effectively control diseases and insect pests, and plant cellular immune factors can be applied to improve plant resistance and make virus DNA break and apoptosis. Strong immune function, induce interferon and active interleukin, inhibit residual virus replication, and promote plant positive energy ecological growth. The mechanism of host plant disease resistance and the principle of pathogen toxicity variation were used to control the reproduction of plant physiological diseases and infectious diseases.
