Problems solved by technology

Unreasonable tillage, over-planting, a large amount of input of agricultural chemicals and aging of ditch facilities are widespread in my country's agricultural farming areas, which have led to widespread thinning of the farmland soil, serious nutrient imbalance, soil compaction, and degradation of soil biological properties. Soil acidification, gleization, and salinization are increasing, the ability to prevent drought and waterlogging is poor, and the soil fertility of cultivated land continues to decline

Abstract

The invention discloses an efficient bio-organic fertilizer and a preparation method thereof. The efficient bio-organic fertilizer comprises a basic nutrition fertilizer comprising nitrogen, phosphorus and potassium, fulvic acid, gamma-polyglutamic acid and functional microorganisms. The basic nutrition fertilizer further comprises 16-23 wt% of medium trace elements, and the medium trace elementsat least comprise two of silicon, calcium and magnesium. The mass of the fulvic acid accounts for 3% or above of the basic nutrition fertilizer, and the mass of the gamma-polyglutamic acid accounts for 2-10% of the basic nutrition fertilizer. The functional microorganisms comprise bacillus subtilis and/or bacillus amyloliquefaciens, and the content of the functional microorganisms is not smaller than 250,000,000/g of the basic nutrition fertilizer. Through the cooperative effect of the gamma-polyglutamic acid and the fulvic acid, the medium trace elements are dynamically chelated and released,the supply capacity of the medium trace elements in soil and the activity of the functional microorganisms are improved, and absorption and growth of crops are improved.

Description

technical field [0001] The invention relates to a bio-organic fertilizer containing gamma-polyglutamic acid, fulvic acid and functional microbial agent and a preparation method thereof, belonging to the field of chemical fertilizer preparation. Background technique [0002] China is a large agricultural country. The quality of arable land is related to the livelihood of the country and the people. Soil is the basis for human survival and the most important resource for economic and agricultural development. Unreasonable tillage, over-planting, a large amount of input of agricultural chemicals and aging of ditch facilities are widespread in my country's agricultural farming areas, which have led to widespread thinning of the farmland soil, serious nutrient imbalance, soil compaction, and degradation of soil biological properties. Soil acidification, gleization, and salinization are increasing, the ability to prevent drought and flood drainage is poor, and the basic soil fertil...
