Problems solved by technology

[0003] Since the 1940s, with the development of science and technology and the needs of agricultural production, fertilizers have been used more and more in the soil, and have become the main means to improve soil fertility, but long-term excessive application of chemical fertilizers will lead to soil compaction and degradation, resulting in various soil-borne diseases, and at the same time, reducing the absorption of nutrients by crop roots
Although the above patents have certain effects in promoting crop growth, preventing soil-borne diseases, and improving soil aggregate structure, the effect is limited

Abstract

The invention relates to a compound fertilizer for improving soil and a preparing method thereof. The compound fertilizer comprises, by weight, 4.5-6.5 parts of improved plant ash, 0.2-1.2 parts of bacillus subtilis, 0.2-1.0 part of yeast, 1.0-2.5 parts of shell powder, 0.6-1.8 parts of buckwheat hull, 0.2-3.0 parts of zeolite, 0.3-1.1 parts of anionic polyacrylamide and 0.5-1.0 part of trace elements. The preparing method includes the steps of culturing microbial liquid, spraying the microbial liquid onto the surface of the prepared mixed raw material, and conducting granulating and drying after even mixing to prepare the compound fertilizer. The compound fertilizer is rich in organic carbon and other bioactive substances, the carbon element lost in soil can be rapidly compensated for, the formation of the granular structure of the soil can be promoted, soil caking is broken, and the soil porosity is increased; the soil acid-base buffering system is adjusted, the proliferation and increase of effective microbial communities are promoted, and the absorption and utilization of plant root systems for nutrients are improved; the water permeable and air permeable functions of the soilare enhanced, and the crop rooting is promoted.

Description

technical field [0001] The invention relates to the field of soil fertilizer technology, in particular to a compound fertilizer for improving soil and a preparation method thereof. Background technique [0002] Soil is the product of rock minerals exposed on the surface through a series of physical, chemical and biological reactions transformed by natural and human factors; soil is composed of three substances: solid, liquid (moisture) and gas. Among them, liquid and gas exist in the soil voids; solid substances mainly include minerals and organic matter, and soil moisture contains a variety of inorganic and organic ions and molecules, thus forming a soil solution; the components of the soil do not exist in isolation, but are closely related , Interact and work together to produce soil fertility. [0003] Since the 1940s, with the development of science and technology and the needs of agricultural production, fertilizers have been used more and more in the soil, and have be...
