With the further deepen the level of China’s agricultural modernization, agricultural production increased demand for agricultural machinery. agricultural machinery development achieved more and more attention, but the agricultural work effect problem of uneven, suitability of agricultural machin ery are becoming increasingly prominent. the domestic and foreign scholars have gradually realized the importance of agricultural application, analyzes the status of research on applicability.in this paper, the domestic and foreign agricultural machinery area, research on the suitability of agricultural machinery significance are described, with hydraulic reversing plough as model put forward to evaluate the applicability of area turnover plow content, method and steps, the paper studies the applicability evaluation system of reversible plow area.The suitable extent in operation conditions and influence factors under differ ent agricultural machinery is different, therefore, is suitable in one area of the farm machinery may not apply to another area.and the applicability of the good or bad degree is related to the interests of the peasants and the stability of agricultural production, 《the popularization of agricultural technology》, 《agricultural machinery testing and appraisal measures 》, 《 The people’s Republic of China, Agricultural Mechanization Promotion Law 》 of agriculture machinery the applicability of the proposed identification requirements, requirements of agricultural machinery research and academic appraisal department provided information for farmers and large farms to buy agricultural machinery, avoid economic loss caused by the farmers for the purchase of agricultural machinery and tools is not applicable.this study is on the the basis of suitable agricultural machinery integration project, through the investigation and performance test, the pooled analysis of the reversible plow test data and information collected, completed the establishment of applicability evaluation system of regional turnover plow.In this paper, through the investigation and analysis, proposes the factors affecting turnover plow regional applicability: in the area of natural conditions, area farming habits, before the work of vegetation coverage, the machinery itself factors, other factors such as the reference standard of evaluation index. national turnover plow, combined with the actual test and expert opin ion, proposed seven personality area reversible plow applicability can evaluation: rate of return slice, the slice breaking rate and the stability of the tilling depth, stability of tillage width, vegetation coverage rate, surface roughness, soil stroke. In the calculation of the test scores of the individual evaluation indexes, the efficacy coefficient method is used to the test results with numerical representation, in the calculation of the applicability of the weight of evaluation index values, combined with expert advice method and AHP to determine the weight of each evaluation index, analysis of the layer analysis method to calculate the weight value of evaluation index commonly used Excel table formula method and Matlab feature vector method and ya AHP software for solving method of three types of computation, calculate the index weight value selection of ya AHP software to solve method and preferred by the consistency ratio size, analyzes four common methods for agricultural machinery applicability evaluation process, namely the performance test, user survey method, the tracking evaluation method, comprehensive evaluation method, and identified by test method on the performance of reversible plow applicability evaluation, put forward a turnover plough fitness concept, product sum calculated area turnover plow fitness and weight value of every evaluation index value through individual scores, with fitness values of quantitative measure the performance of reversible plow good or bad.Taking the hydraulic turnover plow 1LYF-435 as an example, carries on the examination to the structure parameters and test conditions, the test was performed according to plough the evaluation method of suitability require ments for records, analysis of the test data, the results show that the reversible plow evaluation method evaluation of the application of the score. and in the local farmers to implement the applicability of description, verification the correctness and feasibility of the application of evaluation method of reversible plow.
