一、小麦赤霉病发生特点;小麦赤霉病的发生与品种抗病性、小麦抽穗扬花期的温湿度及稻桩带菌率等有密切关系。小麦扬花期遇到15℃以上温度和多雨天气,稻桩带菌率高,且子囊孢子大量成熟释放,在大面积种植感病品种的麦田,就会酿成病害流行。我省小麦赤霉病发生特点,大致可区分为二个类型。
First, the characteristics of wheat scab; wheat scab occurs with the disease resistance, wheat heading and flowering temperature and humidity and the rate of rice piles are closely related. Wheat flowering encountered more than 15 ℃ temperature and rainy weather, the rate of rice piles with high, and a large number of ascospores mature release, in a large area of susceptible varieties of wheat fields, it will lead to epidemics. The characteristics of wheat scab in our province can be roughly divided into two types.
