实时混药式变量喷雾是依据作物对药液浓度的需求进行喷雾，对节约农药、减小污染有积极效果，而混合液的均匀性对喷药效果有重要的影响。依托3 WY-A 3型喷雾机完成了四喷雾头和单喷头的实时混药实验；为提高混药均匀性设计了药液混合器，并为之进行了混药对比实验。实验表明，无混合器时浓度均匀性稍低，最大平均相对偏差为±9％；使用混合器时药液的均匀性得到明显提高，最大平均相对误差为±3％，并达到均匀混液的要求。

Real-time mixing medicine type variable rate spray , which is conducted according to crop demands for con-centration of pesticide , has positive effect on saving reduce pesticide pollution , and the uniformity of mixture has impor-tant influence on the spraying effect .Relying on 3 WY-A3 type sprayer , real-time mixing medicine experiment was com-pleted with four spray heads and single nozzle , and a mixer was designed for improving pesticide uniformity , mixing med-icine comparison experiment was carried on .The experiments showed that the maximum average relative deviation is ±9%without mixer;Liquid uniformity is improved obviously when the mixer is employed , the maximum average relative devia-tion is ±3%, the requirements of uniformity of mixing liquid is meet .
