Study on Evaluation System of Corn Harvester for Silage in Hilly Area of Southwest China
The aim of this paper is to study the evaluation method of corn harvester for silage in hilly area of southwest China.According to the theoretical basis of agricultural machinery selection and re-lated research on the palatability of silage maize,through the method of expert consultation and field re-search,based on the principles of combining qualitative and quantitative,combining theory with practice,combining agricultural machinery with agronomy,etc.,the silage maize harvester was evaluated from mul-tiple dimensions,and the analytic hierarchy process was adopted.Six secondary indexes and 16 tertiary indexes were constructed,which were composed of energy consumption,working efficiency,working ef-fect,post-harvest surface condition,machine safety and palatability of harvested feed.And establish the weight of each index.According to the established type selection evaluation system of silage corn har-vester,three commonly used silage corn harvest-ers,Senrui 4QZ-2400(1),Meside 4QZ-2300(2)and Kunhe Nongzhuang 4QZ-265(3),were se-lected in Luliang County,Yunnan Province for test verification.The results showed that the com-prehensive scores of the three silage corn harvest-ers were 0.76,0.69 and 0.55,respectively.The test results are the same with the use of local farmers,indicating that the evaluation system of corn silage harvester is reasonable,and it provides a certain direction for the development of whole-process mechanization of corn silage in hilly and mountainous areas in China and the research and devel-opment of agricultural machinery enterprises.
