Cow manure and urine integrated organic fertilizer and preparation method thereof

Abstract

The invention discloses cow manure and urine integrated organic fertilizer and a preparation method thereof, belonging to the technical field of organic fertilizer processing. The cow manure and urineintegrated organic fertilizer is prepared by taking fermented padding, microbial preparations, a deodorant and water as raw materials; the padding is pretreated, and the microbial preparations are added for carrying out fermentation; the fermented padding is laid in a cowshed, and the fermented padding and an excrement mixture are cleaned at a time every 3-6 months and are further processed intovarious powdered or granular organic fertilizer products by using a high temperature aerobic composting method, so that commercial production is realized. Compared with the conventional dry and wet depart feces-urine (dry manure) produced organic fertilizer, the cow manure and urine integrated organic fertilizer is lower in production cost, higher in fertilizer efficiency and economic benefit, more ecologically-friendly, and beneficial to realization of large-scale production.

Description

【Technical field】 [0001] The invention belongs to the technical field of organic fertilizer processing, and in particular relates to an organic fertilizer integrated with cow dung and urine and a preparation method thereof. 【Background technique】 [0002] Extensive use of chemical fertilizers has resulted in the death of microorganisms in the soil, the accumulation of salts, and the compaction of the soil. The requirements for the application of organic fertilizers in such fields are more urgent. Cow manure is an important source of organic fertilizer. It contains not only nitrogen, phosphorus and potassium, but also trace elements. However, cattle are ruminants. After repeated chewing of feed, the texture of cow manure is fine and dense. Containing more water, it is a kind of cold fertilizer with slow decomposition and low calorific value. It has been found through research that the water content of livestock and poultry manure such as cow manure and pig manure is usually ...

AI Technical Summary

Problems solved by technology

[0003] With the gradual development of the beef cattle breeding industry in the direction of large-scale and industrialization, the environmental problems of feces pollution are becoming more and more prominent. At present, the conventional method for beef cattle manure is to separate the feces and urine from wet and dry. After the separation, the dry feces, urine and Wastewater and dry manure can be made into organic fertilizer after adding microbial fermentation treatment. Urine and waste water enter the biogas digester for fermentation and sedimentation for harmless treatment. After reaching the standard, they are discharged into the fertile field. It is very inconvenient, in which the useless liquid occupies most of the volume, its operation is troublesome, wastewater treatment requires a sedimentation tank, the economic cost of construction is high, and the fertilizer efficiency is reduced, and the full utilization of resources has not been realized
