运用改进后的大气采样器对棚室内距地面1.5 m高水平面上不同位置采样,将采样后得到的药雾质量浓度采用三次样条函数插值法建立药雾质量浓度分布曲面.对分布曲面分析表明:沿棚室长度方向上,喷头前方10～12 m区间中药雾质量浓度最大,烟雾机作业的有效区域为喷头后方10 m、前方32 m,共42 m;宽度方向上,药雾质量浓度中间低,两侧高.

In order to solve the problem of mass concentration of pesticide fog after application in airtight space, an improved container collecting the air samples was used at different locations in the level of 1.5 m from ground, and curved surface of mass concentration of pesticide fog was established based on cubic spline interpolation. It was showed that the pesticide mass concentration attains maximum at 10～12 m in the front of the nozzle, and the effective regional of cold aerosol sprayer is 42 m, from 10 m in the back of the nozzle to 32 m in the front of the nozzle, in length; and the pesticide mass concentration was lower in the middle of airtight space than the sides of it, in width.
