Problems solved by technology

[0002] In rural areas, a large amount of crop stalks are produced every year. The methods to deal with these stalks are generally discarded or burned, and they can also be used as compost. The existing composts are mainly three types, quick-acting fertilizers, such as commonly used urea, carbon ammonia, and delayed-acting fertilizers. Fertilizers, mainly organic fertilizers made by some farmers, and indirect fertilizers, which do not contain the nutrients needed by crops, mainly change the soil environment by changing the pH and physical and chemical indicators of the soil, such as bacterial fertilizer, lime, gypsum Generally, the straw is crushed, then fermented, and then mixed with a certain proportion of auxiliary materials. However, the organic fertilizer produced by the current composting technology is not fertile enough, so there is an urgent need for an organic fertilizer made of straw and its preparation process.

Embodiment 1

[0013] An organic fertilizer made from straws and a preparation process thereof, comprising the following steps: (1) pretreatment of straws, dividing the prepared straws into dry straws and wet straws according to the water content; (2) the water content is greater than 90% The wet straw should be air-dried or drained, so that the water content of the straw is between 30% and 70%, and then crushed so that the particle size is not greater than 2cm; After soaking the dry straw for 24 hours, crush it so that the particle size is not greater than 2cm; (4) Mix the crushed straw, auxiliary materials, and starter into the mixer and stir evenly, and add an appropriate amount of water to make the water content of the mixture between 55% and 65% %; (5) Fermentation on the stack, stack the evenly mixed straw on the fermentation field into a trapezoidal stack with a bottom width of 1.8m to 3.0m, a top width of 0.8m to 1.0m, and a height of 1.0m to 1.5m. The interval between the piles is 0...

Abstract

The invention relates to organic fertilizer prepared from straw and a preparation technology of the organic fertilizer. The technology comprises steps as follows: pretreatment of straw: the prepared straw is divided into dry and wet straw according to the moisture content and aired, mixed and crushed; the straw, auxiliary materials and a leavening agent are mixed and sent into a mixer to be evenly stirred, and a proper amount of water is added; piling up and fermentation: the mixture is piled into trapezoid strip stacks in a fermentation field and signboards are inserted into the stacks for identification; pile turning is performed to facilitate full fermentation, the fermentation is finished until upper materials have no peculiar smell, and the materials are aired; fermented compost is evenly spread on an airing field, the spreading thickness is not larger than 20 cm, and the materials are turned frequently to be aired evenly and quickly; crushing and screening: the compost can be crushed and screened by a screen after aired until the moisture is lower than 25%; the crushed and screened fertilizer is packaged and put in storage. The organic fertilizer and the preparation technology have the advantages that the cost is low, the efficiency is high, the operation is convenient, the implementation is convenient, and the like.
