Embodiment 1

[0038] Crush 15kg of straw to 2cm in length, spread it evenly in the field, and after flooding with water for 3cm, dissolve 0.3kg of the mixture of ammonium bicarbonate, alkali lignin and sodium lignosulfonate, and spread it evenly in the field; The mixture of chicken manure, horse manure and 0.3g of Bacillus licheniformis, Candida and Bacillus subtilis is evenly sprinkled on the field; after 10 days, the rice straw rots, and the field can be plowed and plowed at this time.

Embodiment 2

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

Embodiment 3

[0042] After crushing 15kg of straw to 7cm first, dissolve 1.2kg of the mixture of ammonium bicarbonate and sodium lignosulfonate in the mud (made with field soil, containing 3% mud), and evenly sprinkle it into the straw. After 1 hour, mix 0.3 The mixture of kg of horse manure, edible fungus residue and alcohol waste liquid and 0.3 g of mixed bacteria of Bacillus licheniformis, Trichoderma viride and Bacillus subtilis were sprinkled into the above-mentioned straw, and mixed evenly. After 9 days, the stalks are decomposed and soft, and can be evenly sprinkled 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 in particular relates to a technical method for the decomposing treatment and utilization of crop straws. Background technique [0002] 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] Farmers in our country have a long history of using crop straw. With the development of agricultural production, the utilization of straw has changed from the original composting manure to direct return of straw to the field. Direct return to the field is to sprinkle the straw directly in the field, and then apply some high-efficiency decomposition compound bacteria, 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 ...
