玉米作为我国三大粮食作物之一,用途已经从食品用粮向饲料和工业用粮转变,其经济效益越来越引起全球的关注。目前,玉米生产从种植到收获绝大部分采用人工操作,生产机械化水平很低,特别是收获机械化水平更低,已成为制约农业机械化发展的瓶颈。大力推广玉米收获机械化技术已成为当务之急。1.推广玉米收获机械化存在的问题(1)地块面积小农村实行联产承包责任制后,土地分割过于零碎,且较为分散.大地块不足0.2hm2,小地块不到0.03hm2,抑制了土地的合理利用和
As one of the three major grain crops in China, corn has changed its use from food grains to feed and industrial grains. Its economic benefits have drawn more and more attention worldwide. At present, most of the corn production from planting to harvesting is manually operated, and the level of mechanization of production is very low. In particular, the lower level of mechanization of harvesting has become a bottleneck restricting the development of agricultural mechanization. To promote corn harvesting mechanization technology has become a top priority. 1. Promote the mechanization of corn harvest problems (1) the small area of the land after the implementation of the system of contract responsibility system, the land fragmentation is too fragmented, and more dispersed .Lands less than 0.2hm2, small plots less than 0.03hm2, inhibition The rational use of land and
