摘要
[目的]为了有效防治2025平茬杨树苗锈头病。[方法]对2025杨树平茬苗采用3种不同的施药措施:雨后及湿热天气后的预防性施药,锈头病发病后施药,锈头病严重时施药。比较3种施药方式下杨树苗的粗度和高度生长情况。[结果]结果表明:预防性施药措施明显优于其他2种措施。[结论]该研究为2025杨树苗生产了提供科学依据和经验性的借鉴。
[Objective] The purpose of the study was to control the rust head disease of 2025 stumped poplar seedling effectively. [Method] 3 different measures of pesticide application were used on the stumped seedllings of 2025 poplar, ineluding preventive pesticide application after rain and damp - heat weather, pesticide application after rust head disease occurred, pesticide application when rust head disease was serious. The growth status of poplar seedling on thickness and height under 3 modes of pesticide application were compared. [Result] The measure of preventive pesticide application was obviously superior to the other 2 measures. [ Conclusion ] The research supplied scientific basis and experience reference for the production of 2025 poplar seedlings.
