Straw decomposing inoculant

Abstract

The invention relates to a straw decomposing inoculant which comprises the following components of 0.2-1.5 billion / g of bacillus subtilis, 0.2-1.5 billion / g of bacillus licheniformis, 20-150 million / g of thermophilic sporotrichosis, 20-150 million / g of Trichoderma Koningii and 20-150 million / g of Phanerochete chrysosporium. Therefore, the straw decomposing inoculant has the advantages of low cost and short decomposing time and is practical and easy to operate.

Description

technical field [0001] The invention relates to a straw decomposing agent. 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 relatively expensive. And the decomposing time is mostly about 15 days. Summer harvest and summer planting, autumn harvest a...

Problems solved by technology

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 relatively expensive. And the decomposing time is about 15 days

Summer harvest and summer planting, autumn harvest and autumn planting have a short time and heavy workload, so they cannot meet the needs of modern agricultural production. Farmers often burn them on the spot

[0004] The current decomposing technology is not yet perfect, and the improvement of the current technology is focused on the screening of bacterial agents, such as Chinese patent document 200710054798.8, a biological decomposing agent for decomposing straw, the operation is cumbersome and complicated, and the catalytic decomposing time takes about 15 days

Chinese patent document 97116556.4 is a method of making straw into an expanded state to destroy lignin, and then crushing it, adding fermentation bacteria, adding fermentation bacteria to ferment and making organic fertilizer, but the expansion process needs to consume a lot of energy

Practical, easy-to-operate, low-cost, and short-maturity straw treatment technologies have not been reported in the literature
