Embodiment 1

[0038] Break 15kg of straw into 2cm and spread it evenly in the field. After 3cm of flooding, dissolve 0.3kg of the mixture of ammonium bicarbonate, alkali lignin and sodium lignosulfonate, and sprinkle it evenly in the field; The mixture of chicken manure and horse manure and 0.3g of Bacillus licheniformis, Candida and Bacillus subtilis mixed bacteria are evenly sprinkled in the field; after 10 days, the rice stalks rot, and the fields can be ploughed at this time.

Embodiment 2

[0040] Break 15kg of straw to 5cm and spread it evenly in the field. After submerging 10cm, dissolve 0.45kg of the alkali lignin and sodium lignosulfonate mixture and spread it evenly in the field; after 2 days, add 0.3kg of chicken manure, The mixture of edible fungus residue and waste liquid of monosodium glutamate and 0.3 g of Bacillus cereus and Streptomyces gracilis mixed bacteria are evenly sprinkled in the field; after 9 days, the rice stalks rot, and the fields can be plowed at this time.

Embodiment 3

[0042] After crushing 15kg of straw to 7cm, dissolve 1.2kg of ammonium bicarbonate and sodium lignosulfonate mixture in mud (prepared with field soil, containing 3% mud), and evenly sprinkle it into the straw. After 1 hour, 0.3 The mixture of 1kg of horse manure, edible fungus residue and alcohol waste liquid and 0.3g of mixed bacteria of Bacillus licheniformis, Trichoderma viride and Bacillus subtilis are sprinkled into the straw and mixed evenly. After 9 days, the straws decompose and become soft, and can be evenly spread into the farmland.

Abstract

The invention discloses a straw decomposing inoculant and a method for fast decomposing straws. The decomposing inoculant comprises a chemical curing agent and a biological curing agent, wherein the chemical curing agent is one or a mixture of more than two of ammonium bicarbonate, alkali lignin and lignin sodium sulfonate; the biological curing agent is a bactericide containing cellulose-decomposing bacteria and an organic matrix, wherein the bactericide containing cellulose-decomposing bacteria is composite bacteria containing more than two of Bacillus licheniformis, Bacillus cereus, Saccharomyces cerevisiae, Candida, Bacillus subtilis, Cellulomonas flavigena, Streptomyces microflavus and Trichoderma viride. The method for decomposing straws comprises the following steps of: crushing the straws, adding water solution of the chemical curing agent, and then adding the biological curing agent. The method of the invention has simple and easy operation, easily obtained materials and lower cost, shortens the decomposing time, enables the straws to be decomposed within 7-10 days, and has excellent popularization value.

Description

Technical field [0001] The invention belongs to the technical field of solid waste treatment, and specifically relates to a technical method for the decomposing treatment and utilization of crop straw. Background technique [0002] More than half of the products of crop photosynthesis exist in straws, which are rich in nitrogen, phosphorus, potassium, calcium, magnesium, and organic matter. It is a multi-purpose renewable biological resource. [0003] Chinese farmers have a long history of using crop stalks. With the development of agricultural production, the use of straw has changed from composting to the direct return of straw to the field. Returning directly to the field is to sow the straw directly in the field, and then apply some high-efficiency decomposing compound flora, which can promote the decomposition of cellulose, hemicellulose and lignin in the straw, and has a certain effect on the maturity of the straw, but the price is more expensive. And the maturity time is a...
