Example Embodiment
[0024] Example 1
[0025] This embodiment provides a straw composting process, which includes the following steps:
[0026] S1: Knead and crush the corn stalks to a length of 8cm-15cm, mix the straw and pig manure at a weight ratio of 56:44, control the moisture content to 60%, the carbon to nitrogen ratio to 28:1, and use fly ash to adjust the pH value. Alkaline, the total weight is 1000Kg, and the mixture is obtained. Compared with the traditional cutting type crushing, the use of kneading crushing is not only more efficient, but also more economical.
[0027] S2: Put the mixture in the compost box, seal the compost box, and use the residual oxygen in the air in the compost box to quickly heat up the mixture in the compost box to 70±2°C, react for 2 days, and obtain the primary material. This step treatment can not only eliminate the miscellaneous bacteria and complete the disinfection, but also allow the straw to expand and soften at high temperatures, better absorb water, enhan...
Example Embodiment
[0031] Example 2
[0032] This embodiment provides a straw composting process, which includes the following steps:
[0033] S1: Crush wheat straw to a length of 8cm-15cm, mix it according to the weight ratio of straw and cow dung 1:1, control the moisture content to 55%, the carbon to nitrogen ratio to 30:1, and adjust it to weakly alkaline with fly ash , The total weight is 1000Kg, and the mixture is obtained. Compared with the traditional cutting type crushing, the use of kneading crushing is not only more efficient, but also more economical.
[0034] S2: Put the mixture in the compost box, seal the compost box, and use the residual oxygen in the air in the compost box to quickly heat up the mixture in the compost box to 70±2°C, react for 2 days, and obtain the primary material. This step treatment can not only eliminate the miscellaneous bacteria and complete the disinfection, but also allow the straws to limit expansion and soften at high temperatures, better absorb water, and ...
