Problems solved by technology

[0008] The production of γ-polyglutamic acid can be produced on a large scale with biological fermentation technology, which can not only improve the nitrogen utilization rate of fertilizers, but also have a certain water retention effect on plants, and can reduce the water consumption required for plant growth. However, as a functional additive of a suitable fertilizer, its role and efficiency are far from being fully realized; how to screen substances that can produce synergistic effects with γ-polyglutamic acid and jointly develop a biological compound fertilizer to improve γ-polyglutamic acid The effective role of glutamic acid provides countries and farmers with more effective and economical microbial compound fertilizers, thereby creating greater social and economic benefits

Abstract

The invention discloses chlorine-based gamma-biological compound fertilizer and a preparation method thereof. The chlorine-based gamma-biological compound fertilizer comprises gamma-poly(glutamic acid), wheat straw extract, microbial agents and secondary elements, namely, nitrogen elements, phosphorus elements and potassium elements. The gamma-poly(glutamic acid) and the microbial agents are integrally prepared through the fermentation process. The wheat straw extract is obtained by extracting and processing young wheat straw seedlings. The secondary elements are obtained through related compound powder. The chlorine-based gamma-biological compound fertilizer comprises 0.1-5.0 parts of gamma-poly(glutamic acid), 3-12 parts of wheat straw extract, 2-6 parts of microbial agents, 20-30 parts of urea, 55-85 parts of monoammonium phosphate and 30-40 parts of potassium chloride, wherein the number of microorganisms in each gram of the microbial agents is two billion or larger. By means of the chlorine-based gamma-biological compound fertilizer, the nitrogen nutrition utilization rate can be increased, and by means of the supplementary effect of synergistic interaction of the gamma-poly(glutamic acid) and the wheat straw extract, the soil microenvironment is improved, the nutrient absorption is promoted, the crop yield is increased, and the disease-resistant, stress-resistant, anti-interference and successive crop prevention capacity of plants is improved.

Description

technical field [0001] The invention relates to the technical field of microbial compound fertilizer production, in particular to a chlorine-based γ-biological compound fertilizer and a preparation method thereof. Background technique [0002] Chemical fertilizers are playing an increasingly important role in modern agricultural production, and the annual consumption of compound fertilizers is very large, about tens of millions of tons per year. Commonly used compound fertilizers are divided into three types: sulfur-based compound fertilizers, nitro-based compound fertilizers, and chlorine-based compound fertilizers. In recent years, various new types of long-acting compound fertilizers have been developed successively. The domestic chemical fertilizer industry mainly uses nitrogen, phosphorus, and potassium as raw materials, and uses physical or chemical synthesis methods to produce three-element compound or compound fertilizers. The production process of NPK compound ferti...
