Abstract

The invention relates to a kitchen waste coupling cotton stalk efficient degradation composite bacterial organic fertilizer which is formed by fermenting a mixture of kitchen waste and cotton stalk by virtue of efficient degradation composite bacteria, wherein the efficient degradation composite bacteria consists of a carrier and a composite bacterial agent, the carrier is corncob powder, the composite bacterial agent consists of No. I and No. II bacterial agents, the bacterial agent is fully mixed with the mixture of the kitchen waste and the cotton stalk in an aerobic fermentation device, the kitchen waste and the cotton stalk are degraded by virtue of the synergistic effect among different bacterial species, the degradation efficiency is improved, the degradation time is shortened, and the substances are rapidly decomposed and recycled to be converted into a fertilizer capable of improving soil. The efficient degradation microbial inoculum can effectively solve the problems of fire disaster, traffic hazard, environmental pollution and the like caused by land occupation or incineration of kitchen waste and cotton stalks caused by landfill.

Description

Kitchen waste coupling cotton stalk efficient degradation composite bacterial organic fertilizer Technical Field The invention relates to the technical field of environmental protection, in particular to a kitchen waste coupling cotton stalk efficient degradation composite bacterial organic fertilizer and a preparation method thereof. Background Under the conditions that the agricultural production scale is continuously enlarged and the urban living standard is continuously improved, the yield of kitchen waste and cotton stalks is obviously increased. In a vast cotton producing area, a large amount of cotton stalks are produced after harvesting cotton every year, and in the Xinjiang area of China, the amount of cotton stalks left each year is considerable. Meanwhile, along with the increasing of the living standard of people, the generation amount of kitchen waste is also continuously increased. In the past, kitchen waste is mainly treated by means of traditional modes such as landfill, incineration and the like, however, the modes have a plurality of defects and are easy to cause environmental pollution. The treatment of cotton stalks also faces the difficulty that a large amount of cotton stalks are discarded at will or directly burnt, which not only results in waste of resources, but also aggravates the atmospheric pollution due to dense smoke generated by burning. Therefore, the kitchen waste and the cotton stalk are coupled, and the efficient degradation of the composite bacteria is utilized to prepare the organic fertilizer. The kitchen waste is rich in nutrients such as nitrogen, phosphorus, potassium and the like, the cotton stalks contain a large amount of organic substances such as cellulose, hemicellulose and the like, and the organic substances and the cotton stalks are coupled to prepare the organic fertilizer, so that the resource value can be fully exerted, the resource utilization of the organic waste is realized, and the resource waste is avoided. Moreover, the organic fertilizer can be converted into organic fertilizer, so that the problems of soil pollution, air pollution and the like caused by landfill and incineration can be effectively reduced, and the ecological environment is obviously protected. The composite bacterial organic fertilizer has rich nutrient components, can improve soil structure, strengthen water and fertilizer retaining capacity of soil, provide long-acting nutrients for crop growth, promote agricultural yield and quality improvement and assist agricultural green sustainable development. Disclosure of Invention The invention aims to overcome the defects of the prior art and provides a kitchen waste coupling cotton stalk efficient degradation composite bacterial organic fertilizer and a preparation method thereof. According to the method, the organic fertilizer is produced by cooperatively degrading the mixture of the kitchen waste and the cotton stalk through microorganisms, so that the recycling of the waste is realized, the land resources are saved, the fire hazards and the traffic accident hazards are eliminated, the resource utilization efficiency is improved, and the soil is improved.
