小麦赤霉病是福建省小麦的主要病害之一。近几年来,小麦播种面积从南到北逐年扩大,高产、抗锈的改良品种普遍推广,总产和单产显著增加。但赤霉病遍及全省,危害严重,是小麦生产发展的一个重要障碍。为尽快控制和消灭小麦赤霉病的危害,促进小麦生产的发展,确保高产、稳产。因此,本协作组在各级党委一元化领导下,分工协作积极开展小麦赤霉病的研究,现将1973—1975年研究初步结果整理于下。一、菌源量 Wheat scab is one of the major diseases of wheat in Fujian Province. In recent years, the sown area of ​​wheat has been expanding year by year from south to north. The improved varieties with high yield and rust resistance have been widely popularized, and the total output and yield have remarkably increased. However, scab belongs to the whole province, causing serious harm and is an important obstacle to the development of wheat production. As soon as possible to control and eliminate the harm of wheat scab, promote the development of wheat production, ensure high yield and stable yield. Therefore, under the unified leadership of party committees at all levels, this cooperative group actively studies the research of wheat scab in its division of labor and collaboration. The preliminary results of the 1973-1975 study are summarized below. First, the amount of bacteria
