1.玉米机收的现状我国玉米种植面积和总产量仅次于美国,居世界第2位。近年来我国的玉米种植面积迅速扩大,产量急剧增长,其发展速度高于小麦、水稻等其他作物。但玉米的机械化收获水平,在3大粮食作物中发展却是最为迟缓,已成为制约农业机械化发展的瓶颈。相比之下,我国小麦机械化收割已实现了很大跨越。据农业部2005年最新统计,我国小麦机收率达82%,比2004年提高了10个百分点。我国另一大粮食作物水稻,近些年机械化收割水平也有较大提
1. Corn machine revenue status China’s corn acreage and total output second only to the United States, ranking second in the world. In recent years, China’s corn acreage has expanded rapidly and its output has risen sharply. Its development speed is higher than that of other crops such as wheat and rice. However, the mechanization of corn harvest, the development of the three major food crops is the most slow, has become the bottleneck restricting the development of agricultural mechanization. In contrast, mechanized harvesting of wheat in our country has achieved a great leap forward. According to the latest statistics from the Ministry of Agriculture in 2005, the harvest rate of wheat in our country reached 82%, an increase of 10% over 2004. Another big grain crop rice in China has also been greatly raised in mechanized harvesting in recent years
