Embodiment 1

[0026] Organic fertilizer composition by weight: organic material (the present embodiment is sawdust) 15%, calcium cyanamide 3% (in the present embodiment, by weight percentage, nitrogen-containing 20%, containing calcium oxide 45%, all the other are Impurities, pH 11.0-12.5), natural zeolite 4%, chicken manure (by dry weight) 78%.

[0027] Choose a relatively flat bare ground as the chicken manure stacking site, spread a layer of organic material with a thickness of 15 cm, and spread fresh chicken manure with a thickness of 40 cm on the organic material, and evenly sprinkle cyanamide by weight percentage. 50% of the total weight of calcium, then spread fresh chicken manure with a thickness of 15 cm, and evenly sprinkle 50% of the total weight of natural zeolite powder by weight percentage, and then spread fresh chicken manure with a thickness of 40 cm, and spread it evenly by weight percentage 50% of the total weight of calcium cyanamide, and then spread 15 cm thick fresh chi...

Embodiment 2-12

[0029] Difference with embodiment 1 is: the proportioning of raw material and material accumulation height are different to some extent (table 1), and preparation method is with embodiment 1.

[0030] Table 1

[0031]

[0032]In the above table, the material is organic material, chicken manure is fresh chicken manure, calcium cyanide is calcium cyanamide, and zeolite is natural zeolite powder. The organic material in Example 2-4 is sawdust, the organic material in Example 5-8 is rice husk, and the organic material in Example 9-12 is straw.

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 the organic 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...
