2025平茬杨树苗锈头病的防治试验

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。

Trial Study on Rust Head Control of 2025 Stumped Poplar Seedling

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 seedlings of 2025 poplar,including 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.
