摘要: 1986—1989年对落叶松落叶病测报技术进行了系统研究,建立了落叶病测报管理决策支持系统.本系统可预测该病测报因子当年值;继而对全省和各地区平均病情指数,轻、中、重发病面积,应防面积发出长、中期预报;并可制定防治指标,编制防治计划,预测防治效益,资料查询等.

关键词: 落叶松, 落叶病, 测报因子, 防治技术

Abstract: The forecasting technique of larch leaf cast was investigated in1986—1989, and the supporting system for this forecast and its management is established, which can forecast the current values of forecasting factors, make long-and-medium term forecasting for mean disease index and epidemi area, determine control threshold, work out control plan and predict control benefit.

Key words: Larch, Leaf east, Forecasting factor, Control technique
