随着我国地膜覆盖栽培技术的发展,覆盖面积迅速扩大,依靠人工来进行覆盖作业已不能胜任,特别是在大风的情况下,人工几乎不能完成覆盖作业。人们就开始研究用机械来进行这项作业,当这种新型的农业机械一出现,就以它良好的作业性能和比人工快得多的生产效率被人们所重视,并迅速在大面积上推广使用。1980年全国只有伊春市农机所研制成2台地膜覆盖机,到1984年就拥有地膜覆盖机万台以上,铺膜面积近200万亩。我国的地膜覆盖机械化也就这样发展起来了。目前,地膜覆盖机械还只能完成铺膜和铺膜播种作业,怎样选择这些机具呢?下面就将我国各种地膜覆盖机械的性能,代表机型作些简单介绍。据有关部门不完全统计,全国已有的地膜覆盖机械,人力牵引的约1800台、畜力牵引的约5000台、拖
With the development of plastic film mulching cultivation technology in our country, the area of coverage has been rapidly expanding. It has become incapable to rely on artificial covering work. Especially in the case of strong winds, the covering work can hardly be done manually. People began to study the use of machinery for this operation. When this new type of agricultural machinery appeared, it was valued by its good working performance and much faster production efficiency than the artificial one, and was quickly popularized on a large scale use. In 1980, only Yichun Agricultural Machinery Co., Ltd. developed 2 film mulching machines, and in 1984, it had more than 200,000 mulching film mulching machines and covered an area of nearly 2 million mu. The mechanization of plastic mulching in our country has also developed in this way. At present, the film mulching machinery can only be completed filming and filming sowing operations, how to choose these tools? Here will all kinds of plastic mulching machinery performance, on behalf of models for some brief introduction. According to incomplete statistics of relevant departments, there are about 1,800 units of machinery and manpower traction in the country and about 5,000 units of animal power traction and towing
