Problems solved by technology

[0003] The development of microbial bacterial agents in agricultural applications in my country is relatively slow. First, due to weak scientific research, there has been no breakthrough in strain screening, domestication, fermentation technology, and strain compatibility.
Second, in terms of application, it is even more out of touch with scientific research, and lacks accurate application data, which makes the development of popularization and application lag behind. Many related products on the market do not meet national standards, and the effect is not obvious, which is not conducive to its popularization.
The third is that most of the current microbial agents use ordinary granulation technology, live bacteria are easy to inactivate, the granules have high moisture content, and agglomeration is easy to occur when fertilizers are sown at the same time, which limits the use and effect of the product

Abstract

The invention relates to the field of microbial agents and in particular relates to a granular microbial agent and a production method thereof. The granular microbial agent is obtained by adding a little water into iron-ore tailings serving as a matrix, molasses serving as a nutrient medium as well as 2wt% chitosan aqueous solution, molasses and clay which serve as binding agents, inoculating a formula strain, and carrying out secondary granulation and air drying. The granular microbial agent can be used for realizing recycling of iron-ore tailings and safe and synergistic simultaneous seed sowing and fertilizer application, so that the granular microbial agent is efficient and economic for development of the modern agriculture.

Description

technical field [0001] The invention relates to the field of microbial inoculum, in particular to a granular microbial inoculum and a production method thereof. Background technique [0002] my country is the world's largest chemical fertilizer user and nitrogen fertilizer producer. Chemical fertilizers do play a pivotal role in my country's agricultural production, but the continuous excessive use of chemical fertilizers has caused serious soil compaction and serious imbalances in soil microorganisms. Soil-borne diseases are becoming more and more serious , soil fertility decreases, and the quality of agricultural products decreases. Moving on, the outlook is worrying. Microbial agents have the advantages of improving soil structure, eliminating soil compaction, developing crop root systems, regulating crop growth, enhancing crop disease prevention and resistance capabilities, improving crop quality and yield, and not polluting the environment. Therefore, microbial agents ...
