How to plant 1, prepare soil and grow vegetables?
Before planting green vegetables, choose suitable soil according to the planting category, plough and apply base fertilizer to increase fertility, and choose healthy and full seeds to soak and germinate and plant them in the soil. The main function of accelerating germination is to break the dormancy period of seeds, improve the survival rate, and cover the surface with dry fine soil to wait for emergence.
2. Seedling raising and transplanting
After the Chinese cabbage seedlings grow, choose healthy seedlings to transplant and water them before emergence, so that the roots of the seedlings are covered with old soil, which plays a protective role. According to the reasonable row spacing, dig planting holes for transplanting, control the planting density, and avoid too dense soil and insufficient nutrients.
3. Appropriate fertilization
Vegetables need enough nutrition during their growth. When planting, topdressing should be appropriate according to the growth stage. When topdressing, nitrogen fertilizer should be used as the main fertilizer, with a small amount of phosphorus and potassium fertilizer, and chemical fertilizer should not be applied alone to avoid steep growth. In addition, the dosage should be strictly controlled each time, and the principle of thin fertilizer and diligent application should be adhered to.
4. Scientific water use
The growth cycle of green vegetables is short, and sufficient water is needed during the growth and development. When the ambient temperature is suitable, water it once a day to make the soil moist without water accumulation. When the ambient temperature is high, water it every morning and evening to increase soil moisture and drain it in rainy season.
