小麦铺膜穴播机性能试验研究

Expermental Study on Capability Experiment of Film-spreading Sinus Seeding Machine of Wheat

在平作旱地对小麦铺膜穴播机进行机具性能试验,选定作业速度、滚筒直径和鸭嘴直径作为主要的性能指标,通过正交试验和极差分析法得出了排种均匀性指标影响程度大小的顺序为:滚筒直径>鸭嘴直径>作业速度。较佳的水平为:滚筒直径为41.5cm,鸭嘴直径为27.6mm(6分水管),作业速度为4.5km/h。该组数据为排种滚筒结构尺寸的确定及拖拉机的作业速度要求提供了依据。试验说明"条播变穴播的二次排种原理"是正确可行的。

According to the capability experiment of film - spreading sinus seeding machine of wheat in dry land, we make the working speed, roller diameter and duck -beak diameter as the main index. With orthogonal, experiment and range analysis, we can draw the effect degree of the＇release seed equality. The effect important is roller diameter, duck - beak diameter and working speed. The best parameter is followed ： the roller diameter is 41.5 cm, duck - beak diameter is 27.6mm, and the working speed is 4.5 km/h. It offers the basis of the roller diameter dimension for release seed and working speed in tractor. At the same time, the experiment explains the principle correct of the secondary release in sinus seeding
