Straw decomposition agent prepared from methane residues

Abstract

The invention discloses a straw decomposition agent prepared from methane residues. The decomposition agent is prepared from the following raw materials in parts by weight: 20-40 parts of methanol residues, 30-60 parts of organic wastes and 5-15 parts of a microbial composite bacterium strains. The straw decomposition agent disclosed by the invention is prepared from the methanol residues; the methanol residues contain lots of bacterium strains, so the decomposition can be fastened; meanwhile, the methanol residues contain the elements such as nitrogen, phosphorus and potassium, so the straw decomposition agent can satisfy the demands of growth of crops when being used as an organic fertilizer and the use of chemical fertilizers is reduced; the raw materials for preparing the decomposition agent are wide in source, low in cost, high in bacterium strain activity and large in living bacterium quantity; by using the decomposition agent, the decomposition time of the straws can be shortened and the decomposition effect of the straws can be enhanced.

Description

technical field [0001] The invention relates to the field of solid waste treatment, in particular to a straw decomposing agent prepared from methane residue. Background technique [0002] my country is rich in straw resources, with an annual output of about 800 million tons, part of which is used to return straw to improve soil quality and increase crop yields. Since crop straw is mainly composed of cellulose, hemicellulose, and lignin, it is difficult to be decomposed by microorganisms in the natural environment. The cycle of decomposition and transformation of straw in the soil is long and cannot be fully utilized. At the same time, it also affects the physical properties of the soil and field problems. As a result, the utilization of straw, an important organic resource, has been limited. In recent years, people have added straw decomposing agents to speed up the process of straw decomposing and promote the effective utilization of straw. Straw decomposing agent can quic...

Problems solved by technology

The disadvantages of this invention are: the cost of the chemical decomposing agent used is high, the decomposing effect is poor, and it is not easy to preserve

The disadvantages of this invention are: the activity of bacteria is low, the decay effect on straw is not obvious, and the decay time is long

The defective that the present invention exists is that the raw material cost used is too high, is difficult to put into production

[0006] At present, other methods of producing straw decomposing agents in China have been retrieved. Some use wheat bran, rice bran, brown sugar, etc. as raw materials, and the production cost is relatively high; ; Some strains produced have low activity, long decomposing time, and insignificant decomposing effect, etc.
