小麦赤霉病是小麦主要病害之一,其病原菌侵染小麦、穗轴后形成生理阻断,导致穗部表现为全部白穗,白穗上小麦籽粒灌浆不饱满,健康小麦粒数量减少。千粒重明显下降,导致小麦出现减产甚至绝产。赤霉病病原菌在小麦中代谢所产生的物质对人体具有一定的毒性,当人畜食用了含有赤霉病毒素的小麦之后常常会引起中毒现象的发生。本文主要结合实际情况,就小麦赤霉病的发生特点和防控策略进行了分析,希望通过本次研究对同行有一定帮助。
Wheat scab is one of the main diseases of wheat. The pathogen invades the wheat and forms a physiologic blockage after the cob such that panicles appear on the panicles. The grain filling on the panicle is not full and the number of healthy wheat grains is reduced. Thousand grain weight decreased significantly, resulting in wheat yield reduction or even absolute. The metabolites produced by the pathogen of Fusarium head blight in wheat are toxic to the human body and are often poisoned when consumed by humans and animals containing the FHV-containing wheat. Based on the actual situation, this paper analyzed the characteristics and control strategies of wheat scab, and hoped that it would be of some help to our colleagues through this research.
