Organic-inorganic compound fertilizer capable of functionally improving soil and production method thereof

Abstract

The invention discloses an organic-inorganic compound fertilizer capable of functionally improving soil and a production method thereof. The preparation method comprises the following steps: mixing plant straws with grass peat soil in a certain proportion, maintaining the water content in a mixed raw material in a cook-suitable range, and selecting and utilizing a proper cooking decomposition agent and reaction process conditions, so as to obtain high-concentration pasty humus cooking liquid; carrying out freezing, crashing and high-temperature and high-pressure sterilization on animal wastes, adding a catalyst and efficient compound microorganisms to ferment so as to obtain an organic pasty fermenting liquid, mixing the pasty humus cooking liquid with the organic pasty fermenting liquid, adding nitrogen, phosphorus, potassium and a multifunctional soil conditioner, and drying and granulating to obtain the organic-inorganic compound fertilizer. By carrying out a field test by virtue of the organic-inorganic compound fertilizer, the soil can be remarkably improved, and the crop yield can be remarkably increased.

Description

technical field [0001] The invention relates to a compound fertilizer, in particular to a functional soil-improving organic-inorganic compound fertilizer and a production method thereof. Background technique [0002] With the rapid development of the chemical industry, the production and application of various fertilizers have been increasing, which has played an important role in promoting the development of agricultural production. However, with the continuous increase in the application of chemical fertilizers, agriculture has a strong dependence on chemical fertilizers. , and the shortcomings of chemical fertilizer application are increasingly prominent. [0003] First of all, the long-term use of chemical fertilizers has caused the decline of soil fertility and serious soil compaction. Excessive use of chemical fertilizers will deteriorate the physical and chemical properties of the soil, block the soil voids, destroy the soil aggregate structure, and cause the imbalan...

Problems solved by technology

Third, the long-term use of chemical fertilizers seriously affects the quality of crops, and the enrichment of chemical residues makes crops endanger human life.

[0004] Although organic fertilizers contain various nutrient elements needed for plant growth, which can improve soil structure and increase soil fertility, most of the nutrients contained in organic fertilizers are organic substances, and the content of N, P, and K is not high, so its The fertilizer effect is slow, and it cannot meet the needs of crops when used alone
