the effects of three profile wheel arrangements in the frontal ,middle and rear positions on the profiling capacity, penetrating angle and depth of furrow opening are studied.
仿形机构是播种机的重要工作机构，在不同仿形机构的理论分析研究中，对仿形轮配置的专门研究却为鲜见，本文集中研究了仿形轮前、中、后三种配置对不同仿形机构的仿形量、入土角、开沟深度的影响。
Also,the value range of some technical parameters,such as furrow depth,irrigation quantity and initial soil moisture,was got through numerical calculation.
抗旱灌水播种是一种解决春旱播种的有效形式,把此方式下的土壤水分运动看成是沿种沟方向垂直剖面上的二维水分运动,根据不同的初边值条件建立了数学模型,用数值计算方法得出了种沟深度、灌水量、土壤初始含水率等技术参数的取值范围。
