通过对中等规模面积的小麦、莜麦保护性耕作中试示范,对保护性耕作技术的适应性和免耕播种机的可靠性进行了考核。试验结果表明:在高原冷凉地区实施保护性耕作技术种植小麦和莜麦是可行的,并能取得良好的增产效益、节本效益及社会效益;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。该示范试验是机械化保护性耕作技术体系完整的补充,为旱作地区大面积推广保护性耕作技术及抗旱增收提供了可靠的经验。
The mid-sized area of wheat, 莜 wheat demonstration pilot demonstration of conservation tillage, adaptability to conservation tillage techniques and the reliability of no-till planters were evaluated. The results showed that it is feasible to cultivate wheat and oatmeal with conservation tillage technology in cool and cold areas of the plateau, and good yield-increasing, cost-effective and social benefits can be obtained. Meanwhile, the no-tillage seeder used in conservation tillage , Stubble stubble in the surface of the work, its reliable performance, good sex, can achieve deep fertilization and no-tillage sowing. The demonstration experiment is a complete supplement to the mechanized conservation tillage system, which provides reliable experience for large-scale popularization of conservation tillage technology and drought-resistant income increase in dryland areas.
