Multifunctional biological organic fertilizer and preparation method thereof

Abstract

The invention provides a multifunctional biological organic fertilizer and a preparation method thereof. The fertilizer is characterized by being compounded from the following raw material components in percentage by weight: 25-35 percent of garden soil, 5-10 percent of active functional bacteria, 5-15 percent of mineral powder, 25-30 percent of organic fertilizer, 15-20 percent of inorganic compound fertilizer, 0.2-5.0 percent of OP-10 dispersing agent, a crosslinking agent which is 0.2-10 percent of weight of a high-molecular polymer saponified solution, 1-3 percent of boric acid, 0.05-0.15 percent of sodium of polyaspartic acid, 0.5-2 percent of trace elements, 0.5-2 percent of a water-retaining agent, 0.5-2 percent of an acid regulator, 1-5 percent of microbial agent, 0.05-0.1 percent of a root growth promoting agent, 0.5-2 percent of a light respiration inhibitor and 0.5-2 percent of a moisture proof agent, totally 100 percent.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a multifunctional bio-organic fertilizer and a preparation method thereof. Background technique [0002] Microbial fertilizer is a relatively new research field of soil microbiology. Its research and development is of great significance to the sustainable development of green agriculture and ecological agriculture, and it has attracted more and more attention from people. [0003] Microbial fertilizers usually refer to a specific type of product containing active microbial bacteria. When used in agricultural production, crops can obtain a fertilizer effect. Substances that cannot be absorbed, such as ineffective nitrogen, phosphorus, potassium, etc., are decomposed and converted into effective nitrogen, phosphorus, potassium, etc. nutrients that can be directly absorbed by crops, and plant stimulating substances, antibiotic substances, etc. are produced during their metabolism. Thereb...

AI Technical Summary

Problems solved by technology

The method of directly blending the two is difficult to mix evenly, which is not conducive to the growth of microorganisms, and the superabsorbent resin is also difficult to play a role, which directly affects the use effect of fertilizers

Microbial strains cannot be wrapped in the cross-linked structure of water-absorbent resin, and the two are still difficult to mix evenly

[0009] Most of the existing superabsorbent resins need to be polymerized and crosslinked at high temperatures above 100 degrees, and the higher the temperature, the harder the texture. death, reducing the effectiveness of microbial fertilizers and limiting its use in microbial fertilizers
