Abstract

The invention discloses a greenhouse vegetable anti-continuous-cropping organic-inorganic compound fertilizer.The greenhouse vegetable anti-continuous-cropping organic-inorganic compound fertilizer is prepared from, by weight, 35-40 parts of silkworm excrement, 15-20 parts of traditional Chinese medicine decoction dregs, 5-10 parts of hickory nut green shells, 45-50 parts of lime nitrogen, 12-16 parts of diammonium phosphate and 8-12 parts of potassium sulfate and 1.5-2 parts of an EM fungicide.The invention further discloses a preparation method of the greenhouse vegetable anti-continuous-cropping organic-inorganic compound fertilizer.The greenhouse vegetable anti-continuous-cropping organic-inorganic compound fertilizer is rich in organic matter, nitrogen, phosphorus and potassium and multiple types of trace elements required for plant growth and comprehensive and balanced in nutrition, and remarkably improves physical and chemical properties of soil.The traditional Chinese medicine decoction dregs, the hickory nut green shells and the lime nitrogen having a residual specific effect are scientifically added, the raw materials play a synergic effect, the problems including soil nutrient supply imbalance, exacerbation of plant diseases and insect pests and deterioration of the physical and chemical properties of the soil caused by continuous cropping of greenhouse vegetables can be fundamentally solved, and meanwhile the problem of high vegetable pesticide residue content, environment pollution and the like can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to an organic-inorganic compound fertilizer resistant to continuous cropping of facility vegetables and a preparation method thereof. Background technique [0002] Facility vegetables are a high-input, high-output and high-efficiency industry. The continuous development of facility vegetables fills the vacancy in my country's off-season vegetable market. However, due to the relatively single variety of facility vegetables, difficulty in replanting, and high multi-cropping index, it also brings a series of repeated cropping problems, resulting in reduced vegetable production or even no harvest. [0003] The main reasons for the problem of continuous cropping of facility vegetables are as follows: 1. Long-term planting of a single variety can selectively absorb some preferred nutrient elements, resulting in an imbalance of soil nutrient supply; 2. Continuous planting ...
