Problems solved by technology

[0005] The technical problem mainly solved by the present invention: aiming at the defects of the current straw composting, such as the slow start of compost fermentation and insufficient utilization of raw materials due to the dense structure of cellulose itself and the characteristics of not easy to degrade, it is easy to cause the loss of nutrients, and the time is long. A method to promote rapid decomposition of straw compost
The composting method of the present invention uses the cellulose-degrading bacteria in the rumen content as the decay-promoting filler, which solves the problems of slow start-up of fermentation of traditional straw composting, insufficient utilization of raw materials, easy loss of nutrients, and long time, and has wide applications. prospect

example 1

[0019] Weigh 4kg of rice husks and wash them with deionized water for 3 times, and after natural drying, immerse in a nitric acid solution with a concentration 5 times the volume of 0.3mol / L, move into an ultrasonic oscillator and oscillate with a power of 200W to immerse overnight, and filter to obtain a filter residue; Put it into the boiler, calcine it with an open flame until it goes out naturally, collect the ashes after burning the rice husks and put them into the reaction kettle, add a 50% sodium bicarbonate solution into the kettle until the rice husk ash is submerged, shake the table and immerse for 10 hours , filter and separate the impregnated filter residue and rinse it with glacial acetic acid until no air bubbles are generated, put the filter residue in an oven, dry overnight at 70°C, and use a porous silicon carrier for future use; collect the rumen content left over from the slaughterhouse according to the solid-liquid ratio of Mix 1:3 with deionized water, stir...

Abstract

The invention relates to a method for promoting quick decomposition of straw compost and belongs to the technical field of agriculture. According to the method, ash left after burning of acid pickling rice husk is taken as raw material, and is subjected to surface modification via baking soda and acetic acid prior to loading rumen content to be made into decomposition promotor, and the decomposition promotor is complexed with corn straw and bed silt to prepare compost. Through the composting method, cellulose decomposing strain in rumen content is taken as decomposition promoting filler, the problems of slow fermentation starting, inadequate raw material utilization, easiness in loss of nutrition and long duration of conventional straw compost are solved, and the method has broad application prospect.

Description

technical field [0001] The invention relates to a method for promoting rapid decomposition of straw compost, which belongs to the field of agricultural technology. Background technique [0002] As one of the most potential organic waste treatment and disposal methods, composting technology has attracted more and more attention from researchers at home and abroad. The main component of organic solid waste, especially agricultural straw, urban greening waste and municipal solid waste, is lignocellulose, which is the most widely distributed and richest carbohydrate on the earth, accounting for more than 60% of the total dry weight of plants in the world . Lignocellulose is mainly composed of cellulose, hemicellulose and lignin, and the proportions of the three are 40%, 20%-30% and 20%-30% respectively. Due to the dense structure of cellulose itself and the non-degradable The characteristics make it difficult to be fully utilized or directly converted and utilized by most micr...
