Analysis And Evaluation Research Of Comprehensive Benefit On The Mechanization Engineering Of Gathering The Used Plastic Film In Cotton Fields

With the development and application of technology in film mulching,the used amount of film is also increasing gradually.However,the used plastic film will induce "white pollution" without rapidly cleared up from farm,and deposit unceasingly,finally,it will be harmful to the structure of soil and reduce the output of the crop.Not only the labor intensity will be big and the work efficiency will be low if gather the used plastic film manually.Moreover it is unable to gather the used plastic film which in the deep place of topsoil,It will cause the cumulative pollution.At the same time,the work of gathering the used plastic film is overlapping with the autumn harvest,autumn ploughing,spring sowing and so on,so the labor force is severe short.The mechanization recycling of the residual film,that can not only overcome the disadvantages which were caused by gather manually,but also the recovery rate and the productivity have the large scale enhancement;And that also reduced farmers' labor intensity,alleviated the labor force stress during the period of recovery.By analysis the detailed parts of mechanization technology on gathering the used plastic film,the paper set forth the feasibility of using the method of mechanization technology.From the different fields, such that economy,society and ecosystem,analysing and evaluating the comprehensive benefits and the profound significance to agriculture by using mechanization technology on gathering the used plastic film, which expect to improve the necessity understanding and know about the real benefts of using that by farmers.It will help to effectively promote the project of gathering the used plastic film.
