Embodiment Construction

[0165] Below in conjunction with specific embodiment the present invention is described in further detail:

[0166] Biological stalk decomposing fungi of the present invention are selected from Trichoderma longbrachiatum Rifai, Aspergillus terreus Thom, Phanerochaete chysos porium Burdsall, Paenibacillus amylolyticus (Nakam1984) Ash et al.1994], Torulopsis candida (Saito) Lodder], as a composite strain combination. Trichoderma longifolia and Aspergillus terreus are fungi that mainly produce cellulose and hemicellulolytic enzymes; Phaneroderma chrysosporium is a fungus that produces lignin decomposing enzymes; Paenibacillus amyloliquefaciens is a bacterium that produces cellulose and hemicellulose Sulfase; Torulopsis albicans, for purification and creation of anaerobic conditions.

[0167] The source of the strains used: all come from the Agricultural Culture Collection of China (ACCC for short)

Abstract

The invention discloses a biological straw decomposition agent and a preparation method thereof and particularly relates to a biological straw decomposition agent taking funguses and bacteria as raw materials and a production method of the biological straw decomposition agent. According to the biological straw decomposition agent, trichoderma longibrachiatum, aspergillus terreus, phanerochaete chrysosporium, paenibacillus amylolyticus and torulopsis candida are taken as compound stains; a cellulolytic enzyme, a semi-cellulolytic enzyme and a ligninolytic enzyme are mainly produced; the strains have good mutualistic symbiosis and metabiosis effects and have no antagonisms. When the biological straw decomposition agent is used, the decomposition agent is uniformly scattered into fields after crop straws (wheat, corns and rice) are crushed and dispersed on the ground; the dosage of the biological straw decomposition agent is 30kg per 1hm<2> and then the straws and the decomposition agent are ploughed under the ground.

Description

technical field [0001] The invention relates to an organic material decomposing agent, in particular to a biological straw decomposing agent using fungi and bacteria as raw materials and a preparation method thereof. Background technique [0002] A large amount of crop straws are produced in agricultural production, and these straws are mainly field crop straws such as corn, wheat, rice, and cotton. Before the 1980s, straw was usually transported home by farmers as living fuel, or used for papermaking, and there was not a lot of straw in the field. In recent years, due to the improvement of living standards, farmers' living energy has gradually been replaced by electricity, natural gas and liquefied petroleum gas, and farmers no longer need to transport straw home as living fuel. A large number of crop stalks existing in the field become a burden in the production and life of farmers. In order to save manpower and material resources, many farmers directly burn crop stalks ...
