Problems solved by technology

[0010] In my country, chemical fertilizers are mainly used in the planting process. Although chemical fertilizers can increase their yield, long-term large-scale single application will easily cause soil compaction, destroy soil structure, and reduce crop quality.

Abstract

The invention relates to a method for preparing a biological organic fertilizer by using a straw decomposition agent, wherein the method comprises the following steps: preparation of the straw decomposition agent; material mixing: mixing straw after crushing with livestock manure according to the weight ratio of (1:1)-(4:1), then adding the straw decomposition agent and water, and composting; and decay process: when the temperature of the composted fermentation substance stack is increased to 50-70 DEG C, turning over the fermentation substances from outside to inside, and composting the fermentation substances for 10 days-15 days, to obtain the biological organic fertilizer. According to the method for preparing the biological organic fertilizer by using the straw decomposition agent, corn soaking water is added as a culture medium in the decomposition process for fermentation production of the decomposition agent, and nutrients of the decomposition agent are increased; under a condition of completion of basic functions, the content of organic matters of the organic fertilizer can be increased. The method has the advantages of simple process, low cost, simple and convenient operation and easy control, is beneficial for industrialized implementation, and has quite high economic benefits.

Description

technical field [0001] The invention relates to the field of bio-organic fertilizers, in particular to a method for preparing bio-organic fertilizers by utilizing a straw decomposing agent. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops. It usually refers to the remaining part of wheat, rice, corn, potato, rapeseed, cotton, sugar cane and other crops (usually coarse grains) after harvesting the seeds. More than half of the photosynthetic products of crops exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc. It is a multi-purpose renewable biological resource, and straw is also a roughage. It is characterized by high crude fiber content (30% to 40%), 5% protein, and lignin. [0003] Crop stalks have a large quantity, variety and wide distribution. The annual output of straw in the world is more than 2.9 billion tons. my country is a major producer of grain and ...
