Production method of nematode-killing microbial organic fertilizer

Abstract

The invention relates to a production method of a nematode-killing microbial organic fertilizer, belonging to the technical field of agricultural fertilizers. The production method comprises the following steps: with agricultural wastes, high-fiber substances, household garbage, landscaping garbage, livestock and poultry manure, mushroom wastes, humic acid and the like as main raw materials, thoroughly decomposing the raw materials under the action of a thoroughly-decomposed inoculant; and adding microbial functional bacteria and chelated trace elements, and conducting compounding to obtain the organic fertilizer. Bacillus thuringiensis contained in the produced nematode-killing microbial organic fertilizer obtained through the production method has a good killing effect on female insectsand eggs of nematodes, can well prevent and kill underground diseases, creates a good living environment for root systems of plants so as to realize yield increase, income increase and quality improvement, can also enhance the stress resistance of crops, well improve the granular structure of soil, increase the organic matter content of the soil and improve the physicochemical properties of the soil, increases the yield by 10% or above, and is an excellent fertilizer for producing green organic food.

Description

technical field [0001] The invention relates to the technical field of agricultural chemical fertilizer preparation, in particular to a production method of a nematicidal microbial organic fertilizer. Background technique [0002] With the rapid development of the chemical industry, the production and application of various fertilizers have been increasing, which has played an important role in promoting the development of agricultural production and made great contributions to solving the food problem in our country. However, with the continuous increase in the amount of chemical fertilizer application, the shortcomings of its application are gradually exposed, which are mainly reflected in the following aspects: 1. High input and low output lead to increased fertilization costs. At present, the utilization rate of nitrogen fertilizer in my country's chemical fertilizer field is only 15%-40%, the utilization rate of phosphorus fertilizer is only 10%-20%, and the utilization...

Problems solved by technology

2. Poor environmental protection, resulting in serious soil compaction

Excessive application of chemical fertilizers will deteriorate the physical and chemical properties of the soil, block the soil pores, destroy the soil aggregate structure, and cause the imbalance of soil nutrients, compaction, pollution and decline in fertility

3. Low crop quality directly threatens the safety of human life

At the same time, nematodes also interact with other viruses such as fungi and bacteria to treat diseases together, causing compound diseases and aggravating the occurrence of diseases
