Straw compost after-ripening enzyme accelerator and use method therefor

Abstract

The invention discloses a straw compost after-ripening enzyme accelerator and a use method therefor. The enzyme accelerator consists of trichoderma produced cellulase and neutral protease AS1.398, wherein the content of the trichoderma produced cellulase is 40-45%. The use method for the enzyme accelerator comprises the steps of chopping straws into small segments with length less than 5cm, carrying out conventional composting on the small segments, sprinkling accelerator enzyme liquid, which is prepared according to the blending ratio of 1: (8-12), to straw compost when the temperature of the straw compost is dropped below 50 DEG C, enabling the enzyme liquid and the straw compost to be uniformly mixed in a layered adding or turning composting manner, and carrying out standing until the straw compost is well-composted. According to the enzyme accelerator, the time for composting is shortened by about 15 days, the content of nutrients in soil is increased, and the growth of plants is promoted; and meanwhile, the use process is safe, non-toxic and harmless, so that the guarantee of food safety and soil environment is facilitated.

Description

technical field [0001] The invention relates to the technical field of straw composting treatment, in particular to a post-ripening enzyme accelerator for straw composting and a use method thereof. Background technique [0002] my country is rich in straw resources, and direct burning has accelerated soil degradation, resulting in the lack of organic matter compensation in the soil and land failure, and the soil ecological environment has fallen into a vicious circle. The pollution of chemical fertilizers to the environment is becoming more and more serious, resulting in soil compaction, biomass reduction, and soil nutrition becoming increasingly simplistic. Crop straw has a high content of organic matter and contains various nutrients needed by crops and microorganisms. The development and utilization of straw resources can maintain soil fertility. Composting is an important way to solve the recycling of agricultural waste, but there are problems such as slow decomposition...

Problems solved by technology

Although in recent years, there have been many studies on microbial agents that promote compost maturity, but the ingredients are often single and the effect is not obvious enough.

In addition, most of the existing research is to inoculate microbial agents or other accelerators at the initial stage of composting. After entering the high-temperature stage, the growth of the flora is affected and it is difficult to survive. Therefore, it is difficult to work on the compost decomposition process after the high-temperature stage. Post-ripening accelerators are of great significance for promoting the maturity of straw compost

In the past, although there were a few studies on post-ripening preparations for straw composting, a variety of materials and chemical reagents were often used. These chemical reagents can often endanger human health through inhalation and skin contact, and are also potentially harmful to the soil environment and have certain biological toxicity. and environmental risks; and the materials used are more and more complex
