Composting conditioner and preparation method thereof

Abstract

The invention relates to the field of composting, in particular to a composting conditioner and a preparation method thereof. The raw materials of the composting conditioner comprises calcium superphosphate, 3,4-dimethylpyrazole phosphate, Bacillus licheniformis, calcium carbonate, borax, silicon dioxide, iron phosphate, urea, starch, vegetable gum and water, and the preparation method comprises the steps: (1) grinding silicon dioxide, (2) stirring calcium superphosphate, starch and urea, (3) preparing a composting agent mixture, (4) preparing a compost ball, (5) adding red litmus paper and (6) performing air drying. The problems that since an existing composting agent has no accurate metric standards for when addition is performed, waste is often caused by excessive addition of the composting agent, or the loss of nitrogen is caused by insufficient addition of the composting agent are solved by designing the composting conditioner and the preparation method thereof, and the defects that large dosage of most conditioners and reduction of ammonia gas or nitrogen oxides cannot be achieved, and the fixation rate of nitrogen is only about 50% are overcome.

Description

technical field [0001] The invention relates to the field of composting, in particular to a compost conditioner and a preparation method thereof. Background technique [0002] At present, straw + livestock and poultry manure composting is one of the main methods to deal with rural non-point source pollution. High-temperature composting can effectively kill insect eggs and most pests and diseases, and is rich in organic matter and nitrogen, phosphorus, and potassium. It is currently widely used Methods. [0003] However, studies have shown that the loss of nitrogen is serious during the composting process, and the loss rate is between 35-76%, and the form of loss is mainly ammonia and nitrogen oxides. Ammonia is harmful to the human body and the atmosphere, and nitrous oxide It is an important greenhouse gas. Nitric oxide and nitrogen dioxide are important precursors of PM2.5, which also pollute the atmosphere to a certain extent. Therefore, in recent years, adding compost ...

Problems solved by technology

[0004] In addition, while existing composting agents increase nitrogen fixation rate and reduce ammonia or nitrogen oxides, they need to be added continuously during the composting process to reduce nitrogen loss and the production of ammonia and nitrogen oxides, while composting agents There is no accurate measurement standard for when to add, which often leads to excessive addition of compost and waste, or insufficient addition of compost to cause nitrogen loss
