Embodiment 1

[0026] A straw decomposed fertilizer, including the following raw materials in parts by weight: 200 parts of straw, the straw is one or any combination of straws of rice, wheat, corn, sweet potatoes, peanuts, rapeseed and other crops or vegetables , 160 parts of animal manure, the animal manure is a combination of sheep manure, pig manure and cow manure, the combination ratio is 5:2:3, 15 parts of EM bacteria liquid, 20 parts of straw fermentation bacteria agent, 100 parts of biogas slurry .

[0027] The method for preparing a kind of straw decomposed fertilizer of the present invention, the described steps are as follows:

[0028] S1. Straw treatment. Dry the straw indoors at high temperature until the temperature reaches 50-65°C, so as to kill the pest eggs in the straw, and then use a grinder for the first crushing to remove impurities such as iron filings, and then carry out the second step. Secondary pulverization to obtain uniform straw powder. The straw fermenting agen...

Abstract

The invention discloses a straw decomposed fertilizer and a preparation method thereof, and belongs to the field of organic fertilizers for crop plantation. The straw decomposed fertilizer comprises,by weight, 200-240 parts of straws, 160-180 parts of animal wastes, 15-19 parts of an EM bacterial liquid, 20-30 parts of a straw fermentation inoculant, and 100-120 parts of biogas slurry. The strawdecomposed fertilizer has the advantages of convenience in storage, easiness in use, sufficient utilization of a decomposed straw and animal waste mixed fertilizer, sufficient fertility and long fertilizer efficiency; and worm eggs and viruses are fully killed in the preparation process, so the problem of plant diseases and insect pests caused by direct returning of the straws to the field insufficient fertility and the problem of additional fertilization due to poor fertility are solved, thereby the rural straw treatment problem is solved, the treatment problem of animal wastes generated by animal breeding is also solved, and the safe and effective organic fertilizer is provided for the farmland.

Description

technical field [0001] The invention relates to the field of organic fertilizer for crop planting, and more specifically relates to a straw decomposed fertilizer and a preparation method thereof. Background technique [0002] Straw is the general term for the stem and leaf parts of mature crops. Usually refers to the remaining parts of wheat, rice, corn, potato, rapeseed, cotton, sugar cane and other crops after harvesting 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, and is a multi-purpose renewable biological resource. [0003] Straw can be used as fuel for cooking in rural areas, but with the continuous development of science and technology, this function has gradually faded, and many farmers directly burn straw in the field, but burning straw will not only destroy the structure of the soil, At the same time, it will pollute the environment. Therefor...
