Bioorganic fertilizer and its production process

Abstract

A bioorganic fertilizer is produced with cake dregs, farm animal excrement and stalk and straw as raw materials and through fermentation with the solid bacteria strain cultured by using lichen bacillus and subtilis bacillus, drying in air or stoving after being throughly decomposed, and crushing. During fermentation, the C / N ratio is controlled at 15-26, organic material water content is controlled at 38-52 % and microbe fermentation temperature is 50-70 deg.C. The present invention has wide material source, low cost and simple production process, and applying the fertilizer can raise the yield and quality of crops, improve physical and chemical characteristics of soil, reduce environmental pollution and shorten the growth period of crops.

Description

technical field [0001] The invention relates to a fertilizer, especially an organic compound fertilizer and a manufacturing method thereof. Background technique [0002] In recent decades, with the application of inorganic chemical fertilizers, the output of agricultural production has continued to increase. However, the increase in the amount of chemical fertilizers and the decrease in the amount of organic fertilizers have seriously damaged the soil structure, reduced soil fertility, and intensified soil compaction. In order to change this situation, sustainable agricultural development On the way, people pay more and more attention to the manufacture and use of organic compound fertilizer. Although the nutrients in organic fertilizers are comprehensive, the effective nutrient content is too low to meet the needs of crops for a lifetime. Therefore, adding appropriate amounts of nutrient elements to organic fertilizers and using microorganisms to d...

Problems solved by technology

It uses high-temperature fermentation and high-temperature drying, which can easily lead to nitrogen loss, and the fermentation strain is single, and the decomposition of organic matter is limited. More importantly, it is a pure fertilizer that has no connection with soil and plants, and cannot be used according to soil conditions. 1. Reasonable use of fertilizer due to the characteristics of crop fertilizer absorption. After application, some nutrients are prone to excess, and some nutrients are seriously insufficient. How to apply the balanced fertilization technology to the preparation of organic fertilizers has not been reported.
