Apply rotten
farm fertilizer. Greenhouse vegetables fertilized with well-rotted farmyard manure. Well-rotted farm fertilizer can avoid the spread of disease and insect eggs in the fertilizer. And avoid putting farmyard fertilizer into the greenhouse and then rotting, which will produce ammonia burn vegetable seedlings.
Reasonable fertilization. Base fertilizer is best applied a week before planting vegetables, and should be mixed with the soil evenly. Fertilizer can be applied at a distance of 7-10 cm from the plant ditch or cave, after fertilizer to cover the soil, watering, combined with plant e-fertilizer super long play fertilizer effect, do not scatter fertilizer directly on the ground or plants, by avoiding fertilizer volatilization or burned vegetable seedlings.
Appropriate amount of
chemical fertilizer. As the fertilizer in the greenhouse is not easy to lose, so excessive application of chemical fertilizer, can cause an increase in the concentration of salts in the soil, the light will affect the normal growth of vegetables, the heavy will lead to secondary salinization of the soil. Therefore, fertilization before fertilization to determine the fertility, fertilization formula, do not blindly apply.
Appropriate amount of microfertilizer. Although the demand for micronutrient fertilizers on vegetables is small, but its role in vegetable metabolism is great. Currently commonly used micronutrient fertilizers are micronutrients such as boron, molybdenum, zinc and iron fertilizers. Microfertilizers are mostly applied as a base fertilizer, and can also be used for seed shaking, seed dipping or extra-root chasing. The range between moderate and excessive micronutrient fertilizer is relatively narrow, so the dosage must be accurate to avoid causing fertilizer damage. And when applying micronutrient fertilizer and the growth regulator of Zhuangti Ling series can be used at the same time to smooth the absorption capacity of nutrients and accelerate plant growth.
