Preparation method of fruit tree bio-fertilizer

Abstract

The invention relates to a preparation method of a fruit tree bio-fertilizer. The method comprises the following steps: composting raw materials are collected; the composting raw materials are subjected to crushing and dreg-removing treatments; the composting raw materials are subjected to mixing and stirring treatment; the composting raw material is subjected to combined fermentation composting treatment, such that a bio-fertilizer is obtained; in a sealed condition, the bio-fertilizer is subjected to stirring operation, wherein ozone is delivered into the bio-fertilizer during the stirring operation process for sterilization and heavy metal ion oxidation treatments, such that bio-fertilizer with relatively high cleanness can be obtained.

Description

technical field [0001] The invention relates to the technical field of fertilizer preparation, in particular to a preparation method of fruit tree biological fertilizer. Background technique [0002] As a large agricultural country, my country is increasingly dependent on the use of chemical fertilizers. However, long-term use of chemical fertilizers will cause many problems, such as sharp deterioration of the physical and chemical properties of the soil, nutritional imbalance, and less and less organic matter content. [0003] In view of the above problems, the application of biological fertilizers to agricultural land can better solve the above problems. However, traditional biological fertilizers, especially farmyard manures, are difficult to effectively remove parasites in the biological fertilizers prepared by natural fermentation of composting and other methods. Insect eggs and pathogenic microorganisms, etc., which lead to low cleanliness of traditional bio-fertilizer...

Problems solved by technology

[0002] As a large agricultural country, our country is increasingly dependent on the use of chemical fertilizers. However, long-term use of chemical fertilizers will cause many problems, such as sharp deterioration of the physical and chemical properties of the soil, nutritional imbalance, and less and less organic matter content, etc.

[0003] In view of the above problems, the application of biological fertilizers to agricultural land can better solve the above problems. However, traditional biological fertilizers, especially farmyard manures, are difficult to effectively remove parasites from the biological fertilizers prepared by composting and natural fermentation. Insect eggs and pathogenic microorganisms, etc., which lead to low cleanliness of traditional bio-fertilizers, both in fertilization operations and in the process of picking edible crops, are likely to pose a threat to human health
