一、引言马铃薯晚疫病在山西各地均有发生,是马铃薯生产的主要障碍。我省近年来对其研究及防治工作可以明显的分为三个发展阶段:(一)解放初期到一九五三年由于未能掌握病害规律,防治工作陷于被动局面,采取的主要措施是田间发病甚至流行后喷射波尔多液;(二)一九五四年以后知道晚疫病的田间流行是由发病中心株所引超,而且中心病株的出现至普通蔓延有一相当时间,同时初步掌握病害发生发展的气象条件,因而有可能进行短期预测预 First, the introduction of potato late blight occurred in all parts of Shanxi, potato production is the main obstacle.
