First, mastering the law of tomato fertilizer demand, applying sufficient fertilizer before tomato planting and using marine silkworm microbial inoculum can effectively improve soil and improve soil permeability.
2. Because tomato is a kind of crop prone to diseases and insect pests, it should be prevented from the early stage. When tomatoes are planted and transplanted, using microbial agents mixed with water can obviously promote the root development of tomatoes, improve the survival rate, kill harmful bacteria in the soil, reduce the occurrence of soil-borne diseases and enhance the ability to resist continuous cropping.
Third, fertilization promotes seedlings. After the tomatoes survive, they should be watered or flushed or drip-irrigated with fully soluble water-soluble fertilizers for 2-3 times, with an interval of 5-7 days.
4. Apply strong fruit fertilizer again. When tomatoes enter the fruit-setting stage, they are washed or drip-irrigated with high-potassium water-soluble fertilizer from sea silkworm, 3-4 times per mu. It can reasonably supplement potassium, calcium and other elements, and obviously improve the yield and quality of tomatoes.
Five, if the cultivation of late-maturing tomato varieties, the growth and fruiting period is longer, we should pay special attention to topdressing in the middle and late stages to prevent premature aging of tomatoes. Affect tomato yield.
