Research On The Popularization And Selection Of Rice Harvester In Changsha County

At present, China's government attaches great importance to agricultural mechanization, agricultural inputs, the level of Agricultural Mechanization in Changsha County has been rapid development, the overall level of the best level of history, and promote the development of agricultural economy in Changsha County, but also to a great extent, the agricultural people from the heavy manual labor.This study is based on the analysis of the domestic and International Harvester research and investigation of Changsha County harvester extension models, the amount of promotion, purchase subsidies based, on the promotion of have a concrete understanding and in the process found in Changsha County harvester promotion problems which exist in the process, including:natural conditions, combine the high cost, low utilization rate, agricultural infrastructure can not meet the harvester work conditions, after-sales service can not keep up, promotion of lack of funds, propaganda is not enough, the lack of awareness, management and training system lag seven aspects more; the problems put forward countermeasures and suggestions, including In seven aspects of:to speed up farmland infrastructure construction, to carry on the moderate scale management of farmland, improve the utilization rate, increase the amount of homework, increase the capacity of scientific research, improve product quality, reduce product price. I hope these measures and suggestions of Changsha County harvester promotion has certain reference function.Application of fuzzy evaluation method for the selection of Changsha County harvester. According to the selection principle of the rice combine harvester, choose the main influence factors, including operation, economy, through sex, adaptability, sustainability, maintainability, security, etc. and based on the opinion of the expert evaluation, the weight determined result of evaluation matrix, finally obtains the result of the evaluation, which combine the merits of the order. The conclusion that, for Changsha County contiguous paddy fields can be selected wells were shut 4LBZ-145C,Tanmar 4LBZJ-140D AG600, Kubota 4LZ-2.5 (PRO688Q) Harvester. For small pieces of rice field, zhongzhou longtian 4LZ-2.2, Futian lei wo 4LZ-1.8 harvester.On the basis of the results of fuzzy evaluation method, the optimization allocation of Changsha County harvester is carried out. Using the method of nonlinear programming, the optimal allocation of Changsha County rice harvester is obtained by using MATLAB as the target function, operating time, operating time, model number, and non negative integer as constraints, and the optimal allocation scheme of Changsha County harvester is obtained.
