Synergist for chemical fertilizer

Abstract

The invention relates to a synergist for a chemical fertilizer. The synergist is characterized by being prepared from the following raw materials in parts by weight: 100-500 parts of tenebrio moliter feces and cow dung, 500-1000 parts of corn straw and tobacco straw, 20-80 parts of perlite, 50-100 parts of vermiculite, 50-100 parts of zeolite powder, 100-500 parts of turf, 20-80 parts of polyaspartate and 30-80 parts of chitosan. The cow dung and tenebrio moliter feces serving as organic fertilizers and the turf serving as an organic matter are fermented, and the zeolite powder has good ion exchange and adsorption effect and good stability, bio-toxicity resistance, oxidation resistance and the like, so that the synergist disclosed by the invention has the beneficial effect of adsorbing heavy metal ions; the synergist can be used for seedling culture or cultivation of greenhouse vegetables, does not harm the soil, and has less influence on crops by using the organic matters; the tenebrio moliter feces can also be used for effectively preventing soil hardening, improving the structure of the soil and prolonging the fertilizer efficiency time.

Description

technical field [0001] The invention relates to a synergist for chemical fertilizers and belongs to the field of agriculturalization. Background technique [0002] In recent years, the use of inorganic fertilizers in agriculture has been increasing, while the use of organic fertilizers has been decreasing. The main components of inorganic fertilizers are inorganic compounds, which have high content of active ingredients and fast action effects, and most of them are easily absorbed and utilized by crops. However, inorganic fertilizers are easy to be lost with rainwater, resulting in eutrophication of the water body, easy to compact the soil, reduce the content of organic matter in the soil, and reduce the production of crops. [0003] In the process of greenhouse cultivation, for a long time, the excessive application of chemical fertilizers and organic fertilizers without harmless treatment has caused serious damage to the greenhouse soil, soil pH imbalance, excessive salt ...

Problems solved by technology

However, inorganic fertilizers are easy to be lost with rainwater, resulting in eutrophication of the water body, and easy compaction of the soil, resulting in a decrease in the content of organic matter in the soil and a reduction in crop production.

[0003] In the process of greenhouse cultivation, for a long time, the excessive application of chemical fertilizers and organic fertilizers without harmless treatment has caused serious damage to the greenhouse soil, soil pH imbalance, excessive salt accumulation, aggravation of diseases and insect pests, etc., seriously affecting the yield and quality of vegetables. It also poses a great threat to human health
