Usually use humus soil, humus soil, peat soil, sawdust, shavings, rice husk, etc. mixed with peat, or you can use fine river sand or sand, perlite, vermiculite, cinder, etc. with humus soil, compost soil, peat Soil mixing.
2, base fertilizer: you can use decomposed organic fertilizer (compost, bean cake fertilizer, manure fertilizer, etc.), NPK compound fertilizer and superphosphate, bone powder, applied and fully mixed during the preparation of the matrix process. It should be noted that the use of different crop base fertilizers is also different, so it can be flexibly mastered. At the same time, you can also refer to the following soilless potted substrate data: 0.75 cubic meters of grass charcoal, 0.13 cubic meters of vermiculite, 0.12 cubic meters of perlite, 3.0 kilograms of limestone, 1.0 kilograms of superphosphate (20% phosphorus pentoxide), 1.5 kilograms of composite Fertilizer (15% for nitrogen, phosphorus and potassium), 10 kg of disinfected and dried chicken manure.
3, topdressing: potted vegetables in the fruit-seeking class, should be comprehensive in fertilization at the seedling stage, the ratio of nitrogen, phosphorus and potassium should be scientifically matched when fertilizing, generally 15 days after planting, fertilization should be applied every 10 days, fertilization It is mainly based on light application of thin compound fertilizer or urea aqueous solution to avoid the use of manure with heavier odor.

4, the top of the top dressing: roots outside the top dressing mainly in the roots to absorb nutrient deficiency, or the plant appears to lack trace elements, or the plant is vigorous to grow long-term use, but also can use the vegetable-specific foliar fertilizer and other trace elements of fertilizer, using a sprayer The solution is sprayed directly onto the leaf surface of the vegetable.
