Design and experiment on concave disc type maize ridge-till and no-till planter
摘要
Abstract
The concave disc type maize ridge-till and no-till planter was designed to solve the problems of straw blocking, bad ridge-clear effect and low working efficiency. The idea was put forward to solve problems by combining the concave disc with flat disc, and the designing of concave disc type ridge-clear device. The key structure parameters were conformed through analysing its moving characters. The ridge-tillage field experimental results with the straw covered showed that, concave disc type maize ridge-till and no-till planter was effective in anti-blocking and ridge-clear effect, and created clear seed bed. The separation space between seed and fertilizer was approximately 47 mm, and good uniformity was shown. Soil disturbance was about 22%, and the straw coverage rate decreased by 75.9% on the seedbed after planting, which could increase soil temperature, enhance seeding quality. The results show important significance for the popularization and application of maize ridge-till and no-till in the northeast of China.关键词
