Coix lacryma-jobi L. var. ma-yuen straw organic fertilizer and preparation method thereof

Abstract

The invention relates to a Coix lacryma-jobi L. var. ma-yuen straw organic fertilizer and a preparation method thereof. Coix lacryma-jobi L. var. ma-yuen straw rich in carbon, nitrogen, phosphorus and organic matter is screened, animal excrement cow dung is added, the conversion rate of microorganisms of bacillus amyloliquefaciens, bacillus licheniformis and bacillus subtilis in the organic fertilizer is increased mainly through wet puffing fermentation, heavy metal pollution of soil is reduced, organic materials are promoted to be mineralized and humified, phytase is secreted, most of phytate in soil is degraded, auxin is generated to stimulate crop growth, and the Coix lacryma-jobi L. var. ma-yuen straw organic fertilizer is better than the additive effect of single cow dung fermentation organic fertilizer or direct field returning of the Coix lacryma-jobi L. var. ma-yuen straw, so that the comprehensive utilization of the Coix lacryma-jobi L. var. ma-yuen straw for preparing the organic fertilizer is exerted to the greatest extent, the fertilizer can supplement soil carbon and nitrogen, can improve soil microorganism survival conditions, promote microorganism breeding, improve soil physicochemical properties and biological activity, improve soil quality, is good in safety performance, free of pollution and long in fertilizer efficiency, can increase and update soil organic matter, and can improve crop yield and quality.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to an organic fertilizer with job's tears and rice straws and a preparation method thereof. Background technique [0002] Xingren City, Qianxinan Prefecture is the "Hometown of Job's tears in China". The planting area of ​​Job's tears ranks first in the country. It has unique planting advantages in the territory. It is located in the Yunnan-Guizhou Plateau. Clay and shale are mainly weathered materials, which are the birthplace of barley and rice planting resources. However, with the increase of crop yield, the annual amount of straw is also increasing. At the same time, straw burning has increased environmental pollution. In order to solve the pollution problem of barley straw incineration, the applicant, under the active promotion of the local government, strengthened the cooperation between industry, university and research institutes, and promoted the formation of an ecologica...

Problems solved by technology

[0005] For example, the Chinese patent number is CN201510620817.3 invention patent, patent name: an organic decomposed fertilizer and its preparation method, which is prepared from decomposed clinker and decomposed auxiliary materials through drying-crushing-mixing-fermentation, wherein the decomposed clinker is made of peat and rock powder , edible fungus residue, corn stalks, chicken manure, vegetable stalks, plant ash, green pruning waste and bone meal; decomposing auxiliary materials include decomposing agent, rhizobia agent, EM bacterial liquid, brassin, wood vinegar liquid and fermentation bacterial agent. The composition of raw materials in the method is complex and the required cost is high

[0006] Another example is the Chinese patent No. CN201210425967.5 invention patent, the patent name: a method of using straw to produce biomass fertilizer, select the raw material wheat straw, use the bacteria in the biogas slurry to easily react with the wheat straw, first decompose the wheat straw, produce A large number of bacterial flora are mixed with nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer and other chemical fertilizers. The fertilizer prepared by this method only selects wheat straw, and the organic nutrition produced by the prepared fertilizer is single, and combined with other chemical fertilizers, it cannot achieve nutrient-rich growth. Desired effect of material fertilizer

[0007] Another example is the Chinese patent No. CN201610009040.1 invention patent, the patent name: a production method of leguminous crop stalk decomposed fertilizer, which is obtained by selecting leguminous crop straw and decomposing agent, wherein the decomposing agent is composed of Bacillus subtilis agent, black Aspergillus agent, high-temperature actinomycete agent, yeast agent, rhizobia agent, and water are mixed. The fertilizer obtained by this method is only used for leguminous crops, and the decomposing agent has a complex composition and high cost

[0008] In the prior art, there is no improvement in microbial conversion rate of barley straw wet puffing and fermentation. The applicant specifically studies the organic fertilizer for planting barley in the soil of Qianxinan Prefecture, the "hometown of barley and barley in China", which can not only improve the local ferrosilicon Yellow soil, clay and karst landform shale weathered soil, and can improve the quality and yield of coix seed planting
