Technical Field

The invention relates to the technical field of organic fertilizers, in particular to a method for preparing an organic fertilizer by performing harmless treatment on household pasture excrement.

Background

With the increase of the national support for herbivorous animals, the domestic sheep breeding industry is rapidly developed. The traditional grazing mode is changed into a standardized, large-scale and intensive mode. However, a family type ecological breeding farm which changes the originally irregular and unregulated stocking into the captive breeding becomes a trend. But the environmental problem caused by the sheep manure along with the increase of the number of the breeding heads can also restrict the development of the family pasture. The organic matter content of sheep manure is higher than that of other livestock species due to the characteristics of sheep food, and the organic matter content of the sheep manure reaches 24-27 percent, if water sources, atmosphere, soil and the like are not treated.

Disclosure of Invention

Therefore, based on the background, the invention provides a method for preparing an organic fertilizer by harmless treatment of domestic pasture excrement, which converts the domestic pasture excrement into the organic fertilizer with high fertility, can realize recycling of waste, can realize energy conservation and environment purification.

The technical scheme of the invention is as follows:

a method for preparing an organic fertilizer by innocent treatment of domestic pasture excrement comprises the following steps:

s1: collecting pasture straws, and crushing the pasture straws into straw powder of 1-2cm for later use; preparing the pasture manure and organic waste for later use;

s2, conveying the straw powder, the pasture manure and the organic waste which are prepared in the step S1 to the field or the area of the grassland where no water is accumulated;

s3: mixing the manure, the organic waste and the straw powder obtained in the step S2 according to a carbon-nitrogen ratio, wherein the preferred carbon-nitrogen ratio is 20-40%;

s4: spraying the bacterial preparation or the decomposition agent into the mixture obtained in the step S3 according to the weight ratio of 1-2%, and then uniformly stirring and fully mixing;

s5: spraying water to the manure piles after the stirring in the step S4 to adjust the water content of the manure piles, preferably, controlling the water content of the manure piles to be 55-65%;

s6: adjusting the pH value of the manure pile in the step S5 by using quick lime or gypsum or acetic acid, wherein the preferable pH value is 5.5-9.0;

s7: piling the manure piles in the step S6 into a strip pile or a groove, inserting a temperature meter into the piles, observing the temperature of the manure piles during the stack retting fermentation, and covering a plastic film on the manure piles to increase the fermentation temperature when the temperature is lower than 50 ℃;

and S8, after 2 weeks, retting the manure pile in the step S7 to ferment into organic fertilizer.

Further, the farm manure in step S1 is sheep manure.
