近几年来,小麦大面积推广了2148、红芒、文革1号、抗锈10号、青海麦等抗锈品种,对解决小麦锈病问题起了决定性作用,但由于这些品种都是以感赤霉病的“欧柔”为亲本杂交育成的,都感赤霉病,因而小麦赤霉病逐渐成为小麦的主要病害。1973年小麦赤霉病大流行之后,我们对小麦赤霉病进行了调查研究,用气象站提供的相对湿度单因素代替过去用小麦扬花期的温度、湿度和菌源等多因素预测当年小麦赤霉病病情的轻重,现将四年来调查研究结果分析如下:
In recent years, large-scale popularization of 2148 wheat, Hongmang, the Cultural Revolution on the 1st, anti-rust 10, Qinghai wheat and other rust-resistant varieties to solve the problem of wheat rust played a decisive role, but these varieties are based on the flu Disease “Europe soft ” is bred for the parental hybrids, are all scab, and thus wheat scab becomes the main disease of wheat. After the 1973 wheat head blight, we studied the wheat scab and used the single factor of relative humidity provided by the weather station to replace the past wheat millet blossoms by temperature, humidity and bacterial sources and other factors The severity of the disease, now four years of research findings are analyzed as follows:
