Bio-organic fertilizer with kitchen garbage as raw material and preparation method thereof

Abstract

The present invention relates to a bio-organic fertilizer with kitchen garbage as a raw material and a preparation method thereof. The bio-organic fertilizer is prepared by mixing kitchen garbage, crop straws and chicken manure, inoculating a strain and then fermenting in a solid state, low-temperature drying and smashing. The strain is a secondary strain liquid obtained by liquid culture of bacillus natto, bacillus subtilis and candida. The bio-organic fertilizer produced by the invention contains probiotics, organic matter, nutrients, humic acid, and also protease, peptides, amino acids and other active substances. According to the invention, the kitchen garbage is fully used, the recycling of kitchen garbage is achieved, the fertilization structure is improved, the proportion of the bio-organic fertilizer in fertilizers is improved, and food security and ecological security are achieved.

Description

technical field [0001] The invention relates to a bio-organic fertilizer and a preparation method thereof, in particular to a bio-organic fertilizer and a preparation method using food waste resource treatment output as a raw material. Background technique [0002] In my country's grain production, the nutrient input of chemical fertilizers accounts for about 80%-90%, and the nutrient input of organic fertilizers only accounts for 10%-20%. However, the amount of organic fertilizer used in developed countries such as Europe, America, and Japan has reached the total amount of fertilizer used 20 or 30 years ago. It has become an internationally recognized standard for soil sustainable development. The amount of chemical fertilizers used in my country is seriously excessive. The amount of urea used per mu of arable land in my country is more than twice that of the United States, more than three times that of Japan, and more than eight times that of Australia. The excessive use o...

Problems solved by technology

[0004] Most of the existing bio-organic fertilizers use poultry manure and crop stalks as the main raw materials, and there is no bio-organic fertilizer and preparation method that uses the output of food waste treatment as raw materials.
