Problems solved by technology

[0015] The present invention overcomes the deficiencies of the prior art, provides a method for producing organic fertilizer by decomposing straw, and solves the problem of too many large pores in the soil caused by direct return of straw to the field for decomposing, and the unreasonable ratio of decomposing agent, which causes insufficient nitrogen in the soil , causing microorganisms to compete with crops for nitrogen, resulting in slow decomposition problems, and the problem that straws are difficult to decompose and transform when they are decomposed, and cannot be used as a fertilizer source for crops in the current season

Embodiment 1

[0033] A method for producing organic fertilizer by decomposing straw, the steps of which are as follows: (1) pulverize the straw with a pulverizer, return the pulverized straw to the pulverizer for further pulverization, make it pulverized evenly, and obtain straw powder; The straw mentioned above is one or more of rice straw, corn straw, potato straw and rapeseed straw; corn straw is preferred in this embodiment. (2) In parts by weight, mix 130 parts of straw minced powder and 100 parts of humic acid to obtain a straw decomposed base material, and carry out composting fermentation on the straw decomposed base material, and the fermentation time is 40 days; Provide sufficient oxygen for aerobic fermentation. (3) Add amino acid, bacterial bag and animal fur to the decomposed straw base material after step (2), stir evenly and enter the pulverizer for pulverization to obtain decomposed organic fertilizer base material, each of which is decomposed organic fertilizer The composi...

Embodiment 2

[0035]A method for producing organic fertilizer by decomposing straw, the steps of which are as follows: (1) pulverize the straw with a pulverizer, return the pulverized straw to the pulverizer for further pulverization, make it pulverized evenly, and obtain straw powder; The straw mentioned above is one or more of rice straw, corn straw, potato straw and rapeseed straw; corn straw is preferred in this embodiment. (2) In parts by weight, mix 170 parts of straw minced powder and 140 parts of humic acid to obtain a straw decomposed base material, and carry out composting fermentation of the straw decomposed base material for 50 days; Provide sufficient oxygen for aerobic fermentation. (3) Add amino acid, bacterial bag and animal fur to the decomposed straw base material after step (2), stir evenly and enter the pulverizer for pulverization to obtain decomposed organic fertilizer base material, each of which is decomposed organic fertilizer The composition share ratio is: 170 pa...

Embodiment 3

[0037] A method for producing organic fertilizer by decomposing straw, the steps of which are as follows: (1) pulverize the straw with a pulverizer, return the pulverized straw to the pulverizer for further pulverization, make it pulverized evenly, and obtain straw powder; The straw mentioned above is one or more of rice straw, corn straw, potato straw and rapeseed straw; corn straw is preferred in this embodiment. (2) In parts by weight, mix 150 parts of straw minced powder and 120 parts of humic acid to obtain a straw decomposed base material, and carry out composting fermentation of the straw decomposed base material, and the fermentation time is 45 days; turn the pile every 13 days, Provide sufficient oxygen for aerobic fermentation. (3) Add amino acid, bacterial bag and animal fur to the decomposed straw base material after step (2), stir evenly and enter the pulverizer for pulverization to obtain decomposed organic fertilizer base material, each of which is decomposed or...

Abstract

The invention discloses a method for producing an organic fertilizer by straw decomposition. The method comprises the following steps: firstly, carrying out secondary crushing on straws evenly, mixing the powder with humic acid and then carrying out aerobic fermentation; adding amino acid, a fungi bag and animal fur, stirring the amino acid, the fungi bag and the animal fur evenly and then feeding the mixture to a crusher for crushing; and carrying out aerobic fermentation to obtain the organic fertilizer. According to the method, the problem of excessive soil macropores since the straws are directly returned to the field for decomposition, the problem that microorganisms and the crop fight for a nitrogen element to cause slow decomposition due to nitrogen deficiency in the soil if a decomposition agent is not reasonable in proportion and the problem that the straws are not easily decomposed and transformed in decomposition and cannot be used as a seasonal crop fertilizer source are solved; and the organic fertilizer becomes the organic fertilizer with practical value.

Description

technical field [0001] The invention belongs to the field of crop straw treatment, and in particular relates to a method for producing organic fertilizer by decomposing straw. Background technique [0002] my country produces a large amount of rice, wheat, corn, oil crops and other straws every year, up to 500 million tons. Generally speaking, the cellulose content of wheat straw, rice straw, and corn straw is about 80%, 75%, and 50%, respectively, the amount of planting powder is about 13%, 15%, and 40%, and the amount of residue is about 10%. In addition to a large amount of organic matter, straw also contains N0.4%, P2O50.2%, K2O51.5%. Therefore, it is not difficult to see that the whole body of straw is a treasure, and its nutritional content is no less than that of the grain itself. [0003] Crop straw is a considerable amount of valuable resources, which can be used as fertilizer, feed, energy, industrial raw materials, etc., and has a very broad application prospect...
