摘要
本文运用模糊隶属度法对小麦赤霉病预测预报技术进行了研究。经对彭山县12年资料拟合,符合率高达91.67％;利用眉山县9年资料进行异地验证,符合率仍达88.89％;对彭山县1987年小麦赤霉病发生程度进行预报验证,结果准确。
A new method applied fuzzy subordinative function to forecast the wheat disease Gibberella zeae was obtained. Fitting tests with informa- tion in the past 12 years in Pengshan county indicated that the average accuracy was about 91.67% and the precision on average was about 88.89% when fitting was tested by data of different regions in the past 9 years within Meishan county. The method was applied to forecast epidemic trend of the disease in Pengshan county in 1987 and a good result was thus obtained.
