摘要: 花椒根腐病的病原菌(Fusarium solani)的菌丝生长以25-30℃、分生孢子萌发以20-30℃为最适宜,孢子在水滴中才能很好萌发,最适pH为5.6-7.0;病菌以菌丝和分生孢子主要从伤口浸入,主要以菌丝和厚垣孢子在土壤及其病根残体上越冬,一般4-5月开始侵染发病,6-8月最严重,10月下旬基本停止蔓延,其发病规律呈初发期、盛发期、停止期的单峰曲线。

Abstract: The mycelium of the pathogen causing root rot on CHINESE PRICKLY ASH suitably growed in 25-30℃; Spores of the pathogen could well germinate only in water, suitable for 20-30℃ with a appropiate pH5.6-7.0. The pathogen infected the host mainly through wounds by its mycelium and spores, and lived through the winter mainly by its mycelium and walled-spores in both soil and rotted root.The disease occurred in April-May, spread in June-August, and stopped in October with the curve of a peak.
