Method for utilizing cornstalks for preparing fertilizer

Abstract

The invention discloses a method for utilizing cornstalks for preparing a fertilizer. The method mainly comprises the steps of mixing and fermenting the cornstalks, animal urine and peat according to the equal proportion; then mixing with a particle potash fertilizer, zinc sulfate, citric acid, ferrous sulfate, copper sulfate and seignette salt; adjusting pH to be acid; then drying and pelleting. The method provided by the invention utilizes the cornstalks for preparing the organic fertilizer, on one hand, organic waste materials are fully reutilized, so that the effects on saving energy and protecting environment are achieved; on the other hand, the straws are rich in organic matters and nutrient elements required for crop growth, so that a strong guarantee is provided for crop growth. According to the method provided by the invention, bacillus subtilis and lactobacillus plantarum are adopted for fermenting the cornstalks, so that active substances are fully decomposed and are adsorbed by the crops conveniently and are promoted to absorb nutrients.

Description

technical field [0001] The invention relates to a method for making fertilizer by using corn stalks, belonging to the technical field of fertilizer processing. Background technique [0002] With the development of agricultural science and technology, chemical fertilizers have also been widely used, but it has caused many problems; such as long-term large-scale application of chemical fertilizers, it will destroy the soil structure and lead to a decline in soil fertility, which will not only significantly reduce the benefit of increasing production, but even cause serious problems. polluted environment. [0003] Compared with chemical fertilizers, microbial fertilizers have obvious advantages in improving fertilizer utilization efficiency, increasing crop yields and protecting the ecological environment; however, their cost is high, resource utilization rate is low, and the effect of increasing production is not as good as chemical fertilizers, so they have not been widely us...

AI Technical Summary

Problems solved by technology

[0002] With the development of agricultural science and technology, chemical fertilizers have also been widely used, but it has caused many problems; such as long-term large-scale application of chemical fertilizers, it will destroy the soil structure and lead to a decline in soil fertility, which will not only significantly reduce the benefit of increasing production, but even cause serious problems. polluted environment

[0003] Compared with chemical fertilizers, microbial fertilizers have obvious advantages in improving fertilizer utilization, increasing crop yields and protecting the ecological environment; however, their cost is high, resource utilization is low, and the effect of increasing production is not as good as that of chemical fertilizers, so they have not been widely used

[0004] At present, most of the corn stalks are disposed of as waste and have not been fully utilized. Even improper treatment such as incineration produces thick smoke and seriously pollutes the environment.
