摘要/Abstract

摘要： 为开发出适宜于飞防的苦参碱可溶液剂，并明确其润湿性能及喷雾性能，本研究采用单因素试验筛选苦参碱可溶液剂的润湿分散剂种类及用量，测试了各配方的热贮和低温稳定性，利用光学接触角测量仪测试制剂的表面张力和接触角，利用水敏纸测试苦参碱可溶液剂在无人机喷雾时的雾滴密度及覆盖率，以此评价药剂的润湿性和喷雾性能。结果显示：BY-125为适宜于苦参碱可溶液剂的润湿剂，且当BY-125用量为1%～5%时，制剂具有较好的稳定性；随着BY-125用量升高，苦参碱可溶液剂的静态表面张力（SST）和动态接触角（DCA）逐渐下降。向稀释液中添加1.5%倍达通后，SST和DCA均分别降低48.78%～52.39%和56.59%～62.81%；桶混1.5%倍达通后，1%苦参碱可溶液剂对燕麦蚜虫麦二叉蚜的防效、雾滴密度和覆盖率较未桶混倍达通时均有显著提高。研究表明，BY-125可用于配制苦参碱可溶液剂，其最佳用量为1%，桶混1.5%倍达通可显著提高苦参碱可溶液剂的润湿性能和沉积性能，本文优化了苦参碱可溶液剂在飞防中的喷雾性能和防治效果。

Abstract: To develop a soluble concentrate (SL) of Matrine suitable for aerial spray and determine its wettability and spray performance, we employed a single factor test to screen the types and quantities of wetting dispersants of Matrine SL, to test the heat storage and low temperature stability of each formula, to determine the static surface tension (SST) and dynamic contact angle (DCA) of preparation using optical contact angle measuring instrument, and to measure the droplet density and coverage of Matrine SL in drone spray using water-sensitive paper. According to the results, when the dosage of BY-125, a wetting agent suitable for Matrine SL, was between 1%-5%, the preparation possessed a better stability. When the dosage of BY-125 increased, SST and DCA of Matrine SL gradually decreased. With 1.5% Betaton was added into the diluent, SST and DCA decreased by 48.78%-52.39% and 56.59%-62.81%, respectively. When the diluent was tank-mixed with 1.5% Betaton, the control of 1% Matrine SL on Schizaphis graminum (Rondani), droplet density and coverage increased significantly, compared with that without Betaton. The current results show that BY-125 can be used to make Matrine SL preparation, with the optimal dosage of 1%, and that the Matrine SL tank-mixed with 1.5% Betaton is of high wettability and deposition performance, which optimizes the spray performance and control efficiency of Matrine SL in drone spray.
