Method for preparing organic fertilizer from straws

Abstract

The invention provides a method for preparing an organic fertilizer from straws. According to the method for preparing the organic fertilizer from the straw, a device for preparing the organic fertilizer from the straw is adopted. The device for preparing the organic fertilizer from the straw comprises a processing shell, a slitting unit and a smashing unit, wherein the slitting unit is arranged on the upper side of the inner wall of the processing shell, and the smashing unit is arranged on the inner wall of the lower end of the processing shell. By means of the device, the method of the invention can overcome the problems that straw is mostly processed in a manual cutting mode when being cut at present, the straw needs to be cut step by step in the manual cutting mode, residual water in the straw cannot be removed, later straw processing is affected, cutting efficiency is affected, and the labor cost is consumed; and the method of the invention can also overcome the problems that it cannot be guaranteed that the smashed straw meets processing requirements and secondary smashing processing needs to be conducted on the straw since straw is generally and directly smashed through a smashing machine and multi-stage smashing cannot be achieved through the smashing machine in the prior art.

Description

technical field [0001] The invention relates to the technical field of production and processing of organic fertilizers, in particular to a method for producing organic fertilizers from straws. Background technique [0002] Organic fertilizer refers to the fertilizer made from animal excrement or animal and plant residues and other by-product resources rich in organic matter, which are fermented and decomposed. Most of the nutrients contained in organic fertilizer are in an organic state, and it is difficult for crops to directly use them. , through the action of microorganisms, a variety of nutrient elements are slowly released, and nutrients are continuously supplied to crops. The common organic fertilizer in agricultural production is the residue of crops, and the straw is the mature stalk of crops such as wheat or corn. With the development of science and technology, people usually carry out a series of processing of this kind of straw into easy-to-use organic fertilizer...

AI Technical Summary

Problems solved by technology

[0003] However, the following problems exist in the production and processing of organic fertilizers at present: 1. Most of the current straw is processed by manual cutting when cutting, but manual cutting needs to be cut gradually, and the residue in the straw cannot be removed The moisture in the straw will affect the later processing of the straw, affect the cutting efficiency, and consume human costs;

[0004] 2. When the existing straw is crushed, the pulverizer is generally used to directly crush the straw, but this type of machine cannot achieve multi-stage crushing, so it is impossible to ensure that the crushed straw meets the processing requirements, so it needs to be processed twice. Crushing processing, thereby increasing unnecessary workload
