High-activity humic acid composite microorganism fertilizer and preparation method thereof

Abstract

The invention relates to a high-activity humic acid composite microorganism fertilizer and a preparation method thereof. The high-activity humic acid composite microorganism fertilizer comprises the following components: 20-50% of activated humic acid, 0-20% of an organic material, 0.2-3% of a special-effect composite functional bacterial agent, 0.2-1.8% of a synergist, 30-60% of inorganic nitrogen phosphorus and potassium, 0.2-3% of trace elements and 0.1-0.5% of additives. The high-activity humic acid composite microorganism fertilizer integrates organic and inorganic nutrition and microorganism compounding and pelleting techniques, and the high-activity humic acid composite microorganism fertilizer has the characteristics of low water content, high hardness, availability in mechanical sowing and the like. The high-activity humic acid composite microorganism fertilizer prepared by the preparation method can be used for improving the soil fertility, improving the soil granular structure, fixing nitrogen in the air, decomposing phosphorus and potassium fixed in the soil, activating the micro-ecological environment of plant root soil, promoting growth and development of crops, enhancing the root system, increasing the utilization rate, reducing the use amount, reducing the soil-borne diseases, improving the anti-disease and stress resistance and increasing both production and yield.

Description

technical field

[0001] The invention relates to a humic acid fertilizer, in particular to a method and application for preparing a high-activity humic acid biological fertilizer by using mineral humic acid and other organic materials. Background technique

[0002] my country is the largest fertilizer market in the world. In recent years, the demand for fertilizers in my country's agricultural production has been increasing. Due to the increase in the price of chemical fertilizers and the pollution of the environment and agricultural products caused by excessive use of chemical fertilizers, people have begun to pay attention to the production of microbial fertilizers. Microbial fertilizer is a kind of microbial living products that can obtain specific fertilizer effects on crops through microbial life activities and their products. It has low production cost, good effect, and does not pollute the environment. After application, it not only increases production, but also impro...
