| 摘 要： | 设计了具有喷头变速摇摆功能和自动进、排药功能的温室摇摆式变量弥雾机。为验证和优化喷雾机的施药效果，以喷雾流量、喷雾距离、喷雾机行走速度和喷头摆动速度为自变量，雾滴分布变异系数为响应值，根据Box-Behnken试验设计原理，采用四因素三水平响应面分析方法，并利用Design-Expert软件建立数学模型，对各因素及其交互作用进行分析。结果表明：4个因素的影响显著性由大到小依次为：喷头摆动速度、喷雾机行走速度、喷雾距离、喷雾流量；喷雾机的最佳喷雾参数为：喷雾流量185mL/min、喷雾距离2m、喷雾机行走速度8cm/s和喷头摆动速度5(°)/s，此时雾滴分布变异系数为1.632%。

| Abstract: | A swing,automatic variables and greenhouse mist sprayer equipped with the sprinkler swing function and automatic dosing and discharge liquid system was presented.In order to verify and optimize pesticide application efficiency of mist sprayer,parameters such as spraying flow rate,spraying distance,sprinkler swing speed and sprayer forward velocity were selected as independent variables,which would influence distribution of droplets deposition.Subsequently,the Box-Behnken experimental design with four factors and three levels was performed,and the mathematical model was established by using Design-Expert software,then the effects of various parameters and their interactions were analyzed as well.The results showed that effects order of four parameters on distribution of droplets deposition were as follows: sprinkler swing speed,sprayer forward velocity,spraying distance,and spraying flow rate.The optimal spraying parameters were spraying flow rate of 185 mL/min,spraying distance of 2 m,sprayer forward velocity of 8 cm/s and sprinkler swing speed of 5(°)/s,then the coefficient of variation of droplets distribution of 1.632% was obtained. |
