A large number of mandarin jackets with orange stems are supplied, with three to five-year crowns, 10 to 25 cm, 10 to 20 cm full crowns.
1. Using straw to produce compound fertilizer
In 20 19, the 200-mu straw biomass resource project, which was built by the state at a cost of 600 million yuan, was completed and put into operation. The project is located in Liuhe District, Jilin Province, China. The project has four production lines of anaerobic low-temperature biomass straw carbonization device and two production lines of carbon-based slow-release compound fertilizer. If all these production lines are put into production, it can produce 654.38 million tons of compound fertilizer and consume hundreds of thousands of tons of straw every year. The establishment of this straw biological recycling project not only solved a large part of the straw utilization problem, but also created huge economic benefits, killing two birds with one stone.
Second, straw production fuel block
Not only is it a utilization method to produce chemical fertilizer, but also a straw fuel production and processing plant has been built in Jixi City, Heilongjiang Province, to process agricultural waste straw, rice husk and corn cob into fuel blocks. The heat generated by two tons of fuel blocks is equivalent to the heat generated by 1 ton of coal combustion, and the economic prospect is very good. According to the cost accounting, one ton of straw can reap the profits of 400 yuan, which is already a public hazard for straw.
Third, straw production feed
Since last year, many places in China have established straw processing plants to produce feed. By crushing straw and adding additives suitable for livestock, 1000 tons of straw can meet the annual consumption of 200 heads in Niu Yi. Although the current production plants are not large in scale, the prospects are still very good.
Generally speaking, straw reuse is the general trend, and straw burning will definitely be phased out in the future. Even if a small amount of burning is allowed, most of them will still be used, so this is a very good market. Friends who feel that farming is not profitable can consider entering this field. Don't feel that you can't, can't do it, or don't make money. By the time you see making money, the market is saturated.
