动力甩刀式小麦固定垄免耕播种机
Powered Hammering Blade No-till Wheat Seeder for Permanent Raised Beds
摘要
Abstract
According to the problems of few available no-till seeders and residues-blocking and bed-damaging during the seeding of wheat in maize residues cover fields in permanent raised beds ( PRB) in northwest oasis farming areas,the new anti-blocking (residue-chopping and throwing by powered L-type hammering blade and residue-cutting by knife type opener) and bed renovation ( bed-reshaping by double-wing plough) ideas were put forward. The powered hammering blade no-till wheat seeder for PRB was designed. The key parameters for L-type hammering blade,opener and double-wing plough were determined. The experiment in maize residue cover fields showed that the seeder was effective in solving residues blocking. Compared with 2BMF-5 no-till wheat seeder,the spring wheat yield was similar and bed renovation effect was better with the decreased soil disturbance.关键词
