Process flow of straw processing organic fertilizer:

1. Straw treatment: First, the straw pulverizer should pulverize the material to a certain degree of fineness, and then an appropriate amount of poultry manure or sludge must be added to adjust the carbon-nitrogen ratio and moisture of the compost material, or add bacteria. and enzymes.

2. Fermentation: It is divided into two stages: one is the pre-fermentation, which can be carried out in the open air or in the fermentation device. Oxygen is supplied to the accumulation layer or the fermentation device through forced ventilation, and livestock and poultry manure is added with straw as the main body. The main fermentation period of compost is about 3 to 10 days. The second is post-fermentation. The semi-finished products after the main fermentation are sent to the post-fermentation process, and the easily decomposable organic matter and the more difficult to decompose organic matter that have not been decomposed in the main fermentation process are further decomposed to turn them into stable organic substances such as humic acid and amino acid. For fully decomposed organic fertilizer products, the post-fermentation time is usually more than 20 to 30 days.

3. Post-fermentation treatment: it can be further dried and pulverized as needed to turn the material into qualified organic fertilizer raw materials.

4. Storage: Compost is generally used in spring and autumn, and must be stored in summer and winter. The storage method can be directly piled in the fermentation tank or bagged, requiring dry and breathable.

Advantages of straw organic fertilizer:

1. Straw organic fertilizer belongs to fertilizer, and its quality is guaranteed. "The quality is better than animal manure, which contains certain heavy metals";

2. Wheat straw and other raw materials are rich in resources and low in cost;

3. The market space is broad in the future. With the development of green production increase model in my country this year, organic fertilizer will become more and more in short supply.
