Deodorant nitrogen-conserving conditioner of livestock manure compost and using method

Abstract

The invention relates to a deodorant nitrogen-conserving conditioner. The using method comprises the following steps: evenly mixing pig manure and crushed straw or other crop straw in a ratio of 2-8:1, wherein the moisture content is between 60 and 65 percent; carrying out simple high-temperature composting by adding 25 to 40kg deodorant nitrogen-conserving conditioner in each 1,000kg compost rawmaterial; and adopting a pile-turning or a forced ventilation mode, wherein the temperature is not more than 70 DEG C during high-temperature composting. The deodorant nitrogen-conserving conditionercomprises 15 to 20kg calcium chloride, 10 to 15kg calcium superphosphate and 3 to 8kg zeolite. The compost becomes thoroughly decomposed after 30-day composting. The deodorant nitrogen-conserving conditioner is characterized in that: the conditioner can reduce odorous substances in the pig manure compost and ammonia volatilization and eliminates odour more than 10 days earlier; moreover, the conditioner increases the content of nitrogen nutrients in a compost product by over 20 percent and reduces nitrogen loss by over 70 percent in the composting process; and at the same time, the conditioner has the advantage of simple and easy operation and is suitable to be used in organic fertilizer factories and vast rural areas.

Description

technical field [0001] The invention relates to a method for using a deodorizing and nitrogen-preserving conditioner to reduce the production of odorous substances and ammonia volatilization in livestock and poultry manure composting, and belongs to an organic fertilizer treatment method. Background technique [0002] my country's livestock and poultry breeding industry has developed rapidly, but the harmless treatment of livestock and poultry manure lags behind. Livestock and poultry manure has caused serious environmental pollution and directly affects the growth of livestock and poultry and human health. At present, about 2.7 billion tons of livestock and poultry manure are produced in rural areas of my country every year. By 2010, the discharge of livestock and poultry manure in my country will reach 4.5 billion tons. On the other hand, livestock and poultry manure is a valuable resource in agricultural production. Domestic livestock and poultry farms produce 15.97 milli...

Problems solved by technology

[0005] Today's research and application of livestock and poultry manure compost deodorization and nitrogen-conserving conditioners are mainly reflected in the application of single minerals or other substances to reduce the production of odorous substances and NH in compost. 3 Volatile, although the operation is simple and easy to use, the deodorization and nitrogen retention effects are not good

Using physical and chemical methods to compost and deodorize, the effect is better, but there are problems such as high investment and operating costs, and serious secondary pollution.

Using biological methods to deodorize and maintain nitrogen in compost may have a good effect in the laboratory, but due to the limitation of microbial activity by environmental conditions, it is difficult to guarantee the effect of deodorization and nitrogen retention in compost
