摘  要：
我国经过10余年努力,一批被动防堵式轻型免耕播种机研制成功,在一年一熟中低产地区得到了大面积应用。但是这些免耕播种机防堵能力有限。20世纪末开始,先后创新多种主动防堵式轻型小麦免耕播种机,防堵能力达到国际领先水平,质量比国外免耕播种机轻50%、价格低80%。国外免耕播种机设计思路是重型、被动防堵,我国则是轻型、按覆盖量采用被动或主动防堵。2007年我国使用各种轻型免耕播种机8万多台,其中轻型高防堵性能免耕播种机2万多台,成为世界上第一个用轻型机具实现保护性耕作的国家。

摘  要：
The foreign no-till seeders are heavy,big and expensive,they are not suitable to the Chinese situation of small size land,small tractor power and poor rural economy,and therefore,developing local light no-till seeders is necessary in China.With 10 year efforts since early 90's of the last century,a batch of light no-till seeders with passive anti-blockage were successfully developed and widely applied in one-crop-a-year region of north China.However,the anti-blockage ability of those seeders were limited and hardly used in high yield area.From 2000,several innovative no-till seeders based on active anti-blockage have been created;their anti-blockage abilities reached to international advanced level,the weight of the seeders 50% lighter and price 80% lower than the foreign no-till seeders.The design ideas of foreign no-till seeder are heavy weight and passive anti-blockage;ours are light weight,passive and active anti-blockage for different yield lands.80 000 more sets of light no-till seeders were used in 2007,among them,over 20 000 sets had high anti-blockage ability with power driven.China became the first country in using light seeders to realize conservation tillage in the world.
