Chicken manure deodorant ammonia-fixing fertilizer and preparation thereof

Abstract

The invention relates to an organic fertilizer, in particular to a chicken manure deodorizing and nitrogen preserving organic fertilizer and a preparation method thereof. Calcium cyanamide, natural zeolite, organic materials are taken as additive materials added to fresh chicken manure for stacking and fermentation treatment so as to prepare the organic fertilizer. The preparation method is characterized by simple process and low cost, and solves the problems of loss of nitrogen nutrients in wastes and environmental pollution in raising chicken. The components of the organic fertilizer based on weight ratio are 10-20% of the organic materials, 2-3% of the calcium cyanamide, 3-5% of the natural zeolite, and 73-84% of the chicken manure on dry basis. The preparation method is as follows: the organic materials, the chicken manure, the calcium cyanamide and the natural zeolite are stacked in layers according to a certain proportion; the outer layer is sprinkled with the organic materials,after 7-10 days of fermentation sealed by plastic cloth, turnover is done mechanically or artificially, then the sealed fermentation is carried out for another 7-10 days by the plastic cloth, and theorganic fertilizer is obtained after being dried in the sun. The organic fertilizer has the advantages of reasonable formula, good nitrogen preserving and deodorizing effects, and easy application, thus being suitable for being used as a fertilizer for producing pollution-free agricultural products.

Description

technical field [0001] The invention relates to the production of organic fertilizer, in particular to a chicken manure deodorizing and nitrogen-preserving organic fertilizer and a production method thereof. Background technique [0002] In recent years, with the rapid development of animal husbandry, the scale of animal husbandry has been increasing day by day, and the problem of livestock and poultry waste pollution has become increasingly prominent. The annual excrement of chicken industry alone is as high as 200 million tons. Improper handling of livestock and poultry manure not only wastes a lot of organic fertilizer resources, but also pollutes the environment. Among them, the problems of nutrient loss, odor pollution, and pollution of surface water and groundwater during chicken manure stacking are the main manifestations. [0003] At present, there are two main aspects of the harmless treatment and resource utilization of chicken manure in my country. One is to prov...
