摘要
1989～1993年对河南省小麦纹枯病发生动态关键因素的研究表明,小麦纹枯病的发生与小麦生长期的日均温度、品种抗病性、播期、播量和施肥水平等有密切关系.小麦拔节期以后,日均气温超过10℃,种植感病品种.播种期提前,播种量过大和偏施氮肥等是加重纹枯病的关键因素.
The results showed that the developments of wheat sharp eyespot were closely related to the early sowing, close planting, excessive nitrogen fertilizer application, planting
susceptible varieties and the diurnal mean temperature (> 10 ℃) in wheat jointing stage. The above factors leaded to high incidence of this disease in Henan province in 1989~1993.
