江淮丘陵地区油菜菌核病发生规律初探

A Preliminary Study on the Occurrence of Rape Sclerotinniose in the Jiang Huai Hills District.

本文对我省江淮丘陵地区油菜菌核病的株发病率、茎发病率及百株茎病斑长度之间的相互关系进行了初步研究,重点探索了茎杆上菌核病的发生规律,建立了几个回归关系式来估算茎发病率和百株茎病斑长度,从而简化了油菜菌核病的田间调查工作。

This paper studied preliminarily the relations among the percentage of diseased plants, the percentage of diseased stems and a hundred stems' disease-spot length of the rape sclerolimose in the Jianghuai hills district,Anhui Province,and also investigated emphatically the occurrence of the rape sclerolimose on the stems. For estimating the percentage of diseased stem and a hundred stems' disease-spot length, their linear regression equations were been made to simplify the survey of the rape scleroliniose in rape fields.
