| 摘 要： | 通过田间试验研究,探索了装配GP—81喷头的运五型飞机喷洒2,4—D丁酯乳油稀释液的雾滴漂移状况,建立了有关数学模型。研究表明,较低蒸发度的水雾滴漂移距离为340m,较高挥发度的2,4—D丁酯漂移距离达700m;雾滴密度和沉降量随下风距离增加而减小较快,雾滴直径减小较慢;气象因子和喷液配方对雾滴漂移有重要影响;三次多项式方程Y=b_0 b_1X b_2X~2 b_3X~3能很好地描述雾滴漂移与下风距离的关系,模型中的参数具有明确的实际意义,提出了喷洒2,4—D丁酯时的有效隔离带宽度。

| Abstract: | The drift of droplets in spraying diluted 2,4-D butyl ester emulsion by Yun-5 aircraft mounted the GP-81 nozzle has been studied,and a mathematical model has also been set up in this paper. As results,the droplet drift distance is 340 meters for the water with the smaller volatility,and 700 meters for the 2,4-D butyl ester with the greater volatility ; the density and amount of droplets decrease rapidly but the diameter decreases smoothly with the distance downwind increasing;the weather conditions and spray liquid fomulations influence greatly the drift;the equation Y=b0 b1X b2X2 b3X3 describles the relation between the droplet drift and the distance downwind well,and the coefficients in the model have a clear practical meaning. This paper also advances an effective buffer zone width in 2,4-D butyl ester aerial application. |
