Abstract:In this paper, the mechanization experiments conducted with the conservation tillage technology to plant spring wheat in cold, windy and sandy areas were evaluated and economically analyzed. The experiments show that conservation tillage technology is feasible for spring wheat. It increases output and reduces costs and promotes the public interest. 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. The experimental results are of substantial practical significance to increase yield with drought alleviated and protect dust storm for dozens of plateau counties around Beijing and Tianjin city.
Keywords:conservation tillage  no-tillage planter  spring wheat  emergence of seedlings rate  yield
