摘要
作者为研究砂仁叶枯病的流行规律进行了田间试验。利用所得的田间调查数据建立了不同时期病害流行速率的预测式。以此为基础探讨了一般自然条件下该病害的流行规律。
Field experiments were arranged to try to find out the mechanism of the epidemic of leaf blight of Amomum villosum. Regression equations on the infection rate at different period were established by using the field data. Based on these equations, the epidemics under ordinary environmental conditions are discussed.
