Z字形摆动喷洒法的药液对靶区覆盖分析

Target coverage analysis of z-shaped swing spraying method

应用几何画图分析法对Z字形摆动喷洒法喷洒药液覆盖的作业靶区进行分析研究,将作业靶区划分为重喷区、漏喷区和单喷区三部分,推算出使用该方法时,喷头喷洒区块的总面积至少是作业靶区面积的2倍,即需要对靶区叠加重复喷洒2遍,才能避免漏喷问题。

The geometric drawing analysis method was used to analyze the target area cove red by the Z-shaped swing spraying.The target area was divided into three types:the overlaps,the skips,and well-sprayed area.It was calculated that the total sprayed area of the Z-shaped pattern spraying should be at least two times the target area,which means repeat spraying once more was needed to avoid the problem of skips.In practice,due to the individual difference of the operators,the application of the swing spraying method will inevitably have the problems of overlaps and skips that will limit the control effect.Therefore,it is necessary to study and improve the application of pesticides as soon as possible.
