Method for composting bio-organic fertilizer

Abstract

The invention relates to a method for composting bio-organic fertilizer, which belongs to production methods of agricultural fertilizer. The method aims at solving the problems that the prior art is difficult to treat and transform a large amount of crop straw husks and shells and similar byproducts, and uses the original industrial microbial fungi in non-agricultural soil. The method is characterized by comprising the composting flows of material preparation, fungi mixing, composting fermentation, inspection and finished products. The main materials comprise 40 to 45 percent of crop straw powder, 35 to 40 percent of rice bran, and 15 to 25 percent of dregs of beans; and the auxiliary materials comprise 3 to 5 percent of coal ash, 2 to 5 percent of bone dust and 10 to 15 percent of local field row soil in terms of the weight of the main materials. 3 to 5 percent of strains in terms of the weight of the main materials and the auxiliary materials are added to the mixture, wherein the strains are locally collected indigenous flora which can effectively improve the soil structure of farmlands and improve the soil biological activity. In addition to a small amount of the bone dust, the rest of the raw materials is readily available crop straw husks and shells and similar byproducts for farmers, and related operations in the flows are simple and easy to learn, thus method shows the advantages of adaptation to local conditions, simplicity and practicability, and suitable popularization in the vast majority of rural areas in China.

Description

technical field [0001] The invention belongs to a method for producing agricultural fertilizers, in particular to a method for composting bio-organic fertilizers. Background technique [0002] Document 1 is Chinese patent CN03111016.9, which discloses "A kind of active organic fertilizer and its preparation method", which is characterized in that wastes such as crop straw husks, animal manure, animal fur hydrolyzate are harmlessly treated, Prepared with wood vinegar liquid, Pengrun soil and other ingredients. In its preparation process, on the one hand, the amount of crop straw husks only accounts for 5-10% of the total weight of raw materials, which is not suitable for processing a large amount of crop straw husks; The treatment of the shells is only crushed and mixed with other raw materials, and after drying and inspection, it becomes a finished fertilizer. Obviously, the crop stalk husk powder that is not processed by microbial fermentation can not be effectively absor...

Problems solved by technology

Obviously, these strains are not the original beneficial bacterial community in the farmland soil. Long-term and large-scale use will inevitably change the composition of the original beneficial bacterial community in the farmland soil. It is still difficult to determine what consequences it will have on the growth of crops.
