Due to the high index of multiple cropland in our country.
Crops are tight. A large amount of straw after harvesting is in urgent need of treatment. The cost of using mechanized land return is higher. Some stalks cannot be decomposed during the season. It will become the host of pests and diseases. Harm to diarrhea; the cost of bio-remediation is also high. And the operation is troublesome. It should not be widely popularized. Therefore, in the harvest season of crops, the phenomenon of incineration of straws occurs frequently, resulting in massive waste of organic fertilizer resources and serious environmental pollution.

For every 667 square meters of straw, it costs only 120 yuan to buy seedlings. Only the output value of commodities reaches as much as 1,000 yuan. If managed well. Each year, 333 square meters of breeding area can produce 2-3 tons of goods or more. The annual profit is 8,000 to 12,000 yuan.
