水稻田农药喷雾分布与雾滴沉积量的试验分析

Testing Analysis on Deposit and Distribution of Pesticide Spraying in Rice Fields

借助于荧光分光光度计测定出雾滴在水稻某一区域的沉积量 ,由此获得雾滴沉积量在水稻植株不同层间分布的规律。结果表明 :在按距离地面 4 0 cm以上、2 0～ 4 0 cm之间、5～ 2 0 cm之间对水稻分层时 ,层间的雾滴沉积量与水稻的高度成正比。采用 Matlab,对试验点上拍摄到的照片进行分析 ,建立了雾滴沉积量与对应的水稻植株面积间的相互关系。

The deposition of spraying droplets was tested with a fluorescence spectrophotometer. The results showed that the deposition amount was in direct proportion to the altitude of rice as the rice plants were bedded in three layers of above 40 cm, between 20-40 cm and between 5-20 cm over the ground. By the aid of Matlab software, the rice images were analyzed and the relationship between the deposition of spraying droplets and the area of rice plant was established.
