Problems solved by technology

[0006] However, these organic fertilizers are made by mixing organic fertilizers with inorganic fertilizers after fermentation, and can only solve the problems of land compaction and salinization. So far, there is no organic fertilizer that can effectively inhibit or kill soil-borne pathogens
The use of chemical pesticides to disinfect the soil will bring problems such as environmental pollution, and the price is expensive, which is not suitable for my country's national conditions

Abstract

The invention relates to sterilized type organic fertilizer. The sterilized type organic fertilizer consists of the following raw materials in percentage by weight: 55 to 70 percent of chicken manure leavening, 6 to 25 percent of plant crushing materials, 5 to 10 percent of organic additive and 6 to 15 percent of inorganic additive. The sterilized type organic fertilizer has high sterilization effect, provides various nutritive elements for crops, has a simple process, and is convenient to use and to be popularized and applied in large scale.

Description

technical field [0001] The invention relates to a bactericidal organic fertilizer and a preparation method thereof, in particular to a bactericidal organic fertilizer obtained by uniformly mixing and secondary fermentation of fermented chicken manure, crushed plants, organic additives and inorganic additives. Background technique [0002] In recent years, the planting area of ​​economically valuable crops such as melons, fruits, vegetables, and flowers has continued to expand, the production area of ​​protected areas has continued to increase, and one crop has been planted year after year, all of which are conducive to the growth and reproduction of soil-borne disease pathogens. And if this kind of disease is not controlled in time, it will cause serious reduction in production or reduce product quality, or even cause extinction. Soil disinfection is one of the important measures to control the pathogenic bacteria of soil-borne diseases, and sunlight disinfection is the best...
