小麦赤霉病发病因素及防病措施

小麦赤霉病是目前威胁我国粮食生产安全(尤其是小麦生产)的重要病害,从全国小麦种植情况来看,小麦赤霉病已经具有病发频繁、病害面积增大等发展趋势,现今赤霉病已经成为小麦生产过程中的常发性灾害。通过分析可知,小麦赤霉病主要与气象条件、小麦品种抗性、菌源量以及生产管理手段等密切相关。由此,从化学防治、生物防治和物理防治3个角度,提出小麦赤霉病的防病措施,如喷洒农药、选择抗病品种和合理密植等。

Wheat scab(also known as Fusarium Head Blight, or FHB) is an important disease that threatens the safety of grain production,(especially wheat production), in China. According to the situation of wheat cultivation in China, wheat scab has a development trend of frequent onst and an increase in the area of the disease. Nowadays, scab has become a frequent disaster in the process of wheat production. Through the analysis, it is known that the pathogenic factors of wheat scab are closely related to meteorological conditions, wheat variety resistance, bacterial source and production management methods.Therefore, from the point of view of chemical control, biological control and physical control, the control measures of wheat scab were put forward, such as spraying pesticides, selecting resistant varieties, properly close planting and so on.
