种子落于种沟后弹跳滚动位移的测定及建模

THE DETERMINING AND MODEL ESTABLISHING OF SEED BOUNCING AND ROLLING DISPLACEMENT AFTER IMPACT ON A FURROW

介绍了种子落于种沟后弹跳滚动位移的测量方法。采用二次通用旋转设计及试验，建立了种子着地速度、着地角度、开沟角度、播种深度和土壤湿度等影响因素与种子弹跳滚动位移的数学模型。为精密播种机田间株距分布预测及计算机仿真研究提供了有效的方法。

A measuring method of seed bouncing and rolling displacement (SBRD) after impact on a furrow is introduced in this paper Using the quadratic general revolving design and tests,a mathematical model among impact velocity,angle,opening furrow angle,planting depth,soil humidity and seed bouncing and rolling displacement is established The study of this paper offers a available method for field plant distribution and computer simulation of precision planter.
