2BM-2免耕播种机的设计及试验研究

随着人类农业生产活动的不断进行,人口的迅速膨胀,要求粮食生产的总产量不断地提高,以满足人口增长的需求.为满足人类对粮食的消耗,掠夺式地开发土地资源,毁林开荒,毁草开荒的现象非常严重.保护性耕作是相对于传统耕作的一种新的耕作技术,是作物茎秆还田和免耕、少耕技术的结合.免耕播种机是保护性耕作能否推广的关键性机具.为此,研究设计了2BM-2免耕播种机,并在不同地表条件下进行了试验,试验收到了良好的效果,为保护性耕作的进一步推广提供了保证.

Device and Experimental Study on 2BM-2 Model the Mulch Seeder of No-tillage

With the unceasing progress of the human agricultural production activity, the population expands rapidly and the total output of grain production advances continually, in order to meet the incessant of population demand. In order to satisfy the human for the cereals consume, the phenomena are very serious for imploring predatorily land resource, destroying forest and imploring badlands, destroying grass and imploring wasteland. The protective cultivation, which is relative to traditional cultivation, is a new cultivation technique which combines with crop straw incorporated into field, no-tillage and reduced tillage. The mulch seeder plays an important role in protective cultivation whether can be widely application. In this paper, author designs 2BM-2 model the mulch seeder is experimented in different the condition of surface of the soil. It obtains better effect and provides assurance for widely application to protective cultivation.
