Organic fertilizer for optimizing soil system environment, preparation method and application thereof

Abstract

The invention discloses an organic fertilizer for optimizing soil system environment, a preparation method and an application thereof, and relates to the technical field of organic fertilizers. The organic fertilizer includes, by weight, 200000 parts of chicken manure, 20000-40000 parts of vermiculite, 30000-50000 parts of peanut powder, 100-200 parts of a photo-catalyst, 2-4 parts of bacillus subtilis bacterial powder, 2-4 parts of bacillus mucilaginosus bacterial powder, 2-4 parts of bacillus licheniformis bacterial powder, 2-4 parts of mycorrhiza fungi bacterial powder, 2-4 parts of azotobacter vinelandii bacterial powder, 2-4 parts of streptomyces bacterial powder, 2-4 parts of soil actinomycete bacterial powder, 250-350 parts of beauveria bassiana bacterial liquid, 250-350 parts of metarhizium anisopliae bacterial liquid, 250-350 parts of bacillus thuringiensis bacterial liquid and 250-350 parts of lactic acid bacteria liquid, wherein the living bacteria numbers of the bacterial liquids of the beauveria bassiana, metarhizium anisopliae, bacillus thuringiensis and lactic acid bacteria are all not less than 10 billions / ml. The organic fertilizer can increase organic substance content in soil, increase utilization rate and solve a problem of soil caking, can increase yield and improve quality of crops and further increase economic benefit. The organic fertilizer also can prevent and control underground pests and improve growth environment of plants.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers. Background technique [0002] In recent years, my country's soil problems have become increasingly prominent, and food safety problems caused by soil problems are also emerging in endlessly. Soil compaction is one of the common and difficult problems in the current soil problems, which seriously affects the development of agriculture. [0003] Reasons for formation: [0004] 1. Excessive application of chemical fertilizers [0005] The content of organic matter is an important indicator of soil fertility and aggregate structure, and the reduction of organic matter leads to soil compaction. Soil organic matter is an important part of soil aggregate structure. The decomposition of soil organic matter is achieved by the activities of microorganisms. After excessive nitrogen fertilizer is applied to the soil, the nitrogen supply of microorganisms increases by 1 part, and the correspo...

[0008] 2. Long-term use of groundwater for irrigation is also likely to cause surface soil compaction

[0010] Plant roots consume energy to absorb nutrients, and the main source of energy is the aerobic respiration of root cells. This process requires a certain amount of oxygen, soil compaction, poor soil permeability, and insufficient oxygen hinder the respiration of plant roots. detrimental to plant growth

Moreover, the soil is compacted, the soil fertility is not ideal, the soil pores are not ideal, and the soil aggregate structure is small. These affect the activities of soil microorganisms and also affect the growth of plants.
