Abstract

The invention provides a livestock / poultry manure-straw coupled field returning method. Cellulase, proteinase, lipase, microzyme, deodorizing bacterium and other fermentative bacteria are added into livestock / poultry manure to shorten the manure fermentation time; the livestock / poultry manure is used as a carrier for production, reproduction and application of the straw decomposing bacterium, so that the quantity of the fermented decomposing bacterium is increased by 8-20 times; and no odor emits in the manure fermentation process under the actions of the proteinase and lipase. By organically combining the livestock / poultry manure field returning and straw mechanical pulverization field returning, and the livestock / poultry manure is used as a crop straw accelerator to accelerate the rotting of the straws under the action of the mixed bacteria in the manure. Compared with the single straw mechanical pulverization field returning process, the method obviously shortens the straw rotting time, solves the problem that the emergence of seedlings of the seeds can be influenced during seed sowing since the straws can not be easily rotten and returned to the field, and is capable of obviously improving the aggregate structure in soil and enhancing the contents of organic matters, nitrogen, phosphorus and potassium in the soil. Compared with the straw pulverization-stack retting fermentation field returning process, the method is simple, simplifies the application links, is easier to operate, and saves abundant human resources and material resources.

Description

technical field [0001] The invention provides a method for coupling and returning livestock and poultry manure and straw to the field, which belongs to the technical field of agricultural production. Background technique [0002] my country produces nearly 700 million tons of straw every year, ranking first in the world. Due to the low comprehensive utilization rate of straw, straw has become a "surplus" in rural areas, resulting in open burning of straw and polluting the environment. Returning straw to the field as fertilizer is an effective method to solve the surplus of straw and improve the soil environmental conditions. Since the main components of straw are cellulose and hemicellulose, they are not easy to rot, which restricts the utilization of straw returning to the field as fertilizer. At present, there are two methods of mechanized straw returning to the field: one is to crush the straw mechanically, deeply plow it, bury it and return it to the field, and use the...
