农民和园丁们耕作了几个世纪，但是现在他们中很多人开始采取少耕或免耕方法，也称保护性耕作。
Farmers and gardeners have turned the soil for centuries. But many now believe in no-till or reduced tillage, a method also called conservation tillage.
免耕还能保持土壤中的水分，保护像蚯蚓这样的有益生物。
It also keeps water in the soil and protects helpful organisms like earthworms.
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。
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.
为此，中国农业大学保护性耕作研究中心提出了对行播种的思路，并设计出了一种小麦对行免耕播种机。
For this problem, an idea of sowing wheat following the maize rows is presented by conservation tillage research center in China Agricultural University.
在我国北方一年两熟地区推广实行保护性耕作技术体系过程中，玉米收获后免耕播种小麦是一直困扰的难题。
Planting wheat without tillage after maize harvesting is a hard problem through the extension of conservation tillage technology system in the district of two crops one year in north China.
本文简要介绍了一种新型研制的保护性耕作机具——玉米免耕施肥播种机的结构设计特点与实际使用效果。
This paper introduces briefly the trait of the structure and using effect of a new-design conservation tillage machine, combined machine with no-tillage and fertilization and sowing of corn.
根据保护性耕作技术的推广要求，研制和生产新型免耕播种机势在必行。
It is imperative to develop and produce the no-till seeder for the Conservation tillage technology in accordance with the promotion requirements.
同时，保护性耕作所使用的免耕播种机，在秸秆残茬覆盖的地表工作，其性能可靠、通过性好。能实现化肥深施和免耕播种。
The conservation tillage mechanism works well. It can pass through soil surface that is covered with crop straws and residues to sow seed with no-tillage and deeply spread fertilizer at the same time.
