Problems solved by technology

Some existing utilization methods, such as straw returning to the field, straw feed, straw bacteria cultivation, straw biogas and many other methods, cannot completely solve the problem of comprehensive utilization of straw. The conclusion of the investigation is that the remaining amount of corn straw is more than 50% at present
In addition, these utilization methods have a single product, high cost, and inconspicuous benefits, which limit the actual utilization prospect

Abstract

The present invention discloses a process for co-producing a functional bio-organic fertilizer and plant fibers by using corn straws. According to the process, raw materials comprise corn straws, breeding excrements, edible fungi culture medium wastes and other organic waste assistant materials, and processes of puffed dissociation, screening separation, fermentation and the like are performed to produce a bio-organic fertilizer, wherein the organic matter content is high, and the bio-organic fertilizer is easily absorbed by plants. With the process of the present invention, plant fibers can be further co-produced, wherein physical performance indicators of the produced fibers completely meet standards of papermaking corrugated base paper, and the fibers can be used for wrapping paper papermaking.

Description

technical field [0001] The invention relates to a process for producing functional bio-organic fertilizer and co-producing plant fiber by using corn stalks. Background technique [0002] At present, the annual production of more than 100 million tons of corn stalks in our country has not been well utilized. A large number of straws are abandoned in the fields, and some are burned on the spot, which not only causes waste, but also brings fire hazards and air pollution. . Therefore, it is imperative to develop new ways to develop corn stalks. Today, with the development of science and technology, the prospect of straw development is even broader. As an important biomass resource, corn stalks not only have a high combustion value, but also contain about 5% protein, about 30% cellulose, and a certain amount of calcium, phosphorus and other minerals. The nutritional value of 1 ton of ordinary straw , which is equivalent to the nutritional value of 0.25 tons of grain. Some exi...
