Study On Popularization For Mechanization Of Comprehensive Utilization Of Crop Straw

The mechanized technology of straw of crops integrated utilization is popularized and applied which is very important to agricultural sustainable development, increase the farmer' income and foster the new growth areas of country's economy.Nowadays, the crop production sector produces over 600 million tons of the straw of crops every year in China. About two thirds basically gets to be preliminarily used. One third is still remnant. In order to save time and be convenient, the farmers usually set the straw of crops on fire directly. It not only pollutes the environment, but wastes the resource. The department of agricultural mechanization of the central and local have paid more attention to develop and popularize some integrated utilization technology for solving this problem. In despite of making some progresses, it is not solved in full scale, and the straw of crops is still set on fire from time to time, even very serious sometimes. Every year, the stalk is directly set on fire over 200 million tons in China. It wastes the valued reproducible resource. Even worse, it forms large area pollution to the environment.The object of this research is the mechanized technology of integrated utilization of straw of crops. And the research adopts the special research mode, which combines the document retrieval method, the conversational method with the positive research method. This research emphasizes on two aspects which are the theory and the practice.
