川东北地区小麦赤霉病重发原因及绿色防控对策

Causes and Green Prevention and Control Measures of Wheat Scab in Northeast Sichuan

小麦赤霉病危害严重,一旦暴发,该病害容易导致小麦成穗白枯,千粒质量降低,产量严重减产,且该病原菌产生的真菌毒素对人畜禽有害,丧失食用价值,影响产品质量安全.基于此,本论文系统综述了小麦赤霉病的发生特点与规律,并系统分析了影响川东北地区小麦赤霉病发生的原因,并从选育抗病品种、健身栽培、田间管理、精准科学用药等方面归纳总结了控制小麦赤霉病的绿色防控技术.

Wheat scab is a serious hazard. Outbreak of wheat scab could seriously reduce the yield of wheat by causing white and dry spike, reducing the weight of one-thousand grains. The mycotoxin produced by pathogen is harmful to human, livestock and poultry. Therefore, the pathogen infected grains could lose edible value, affecting product quality and safety. Based on this, this paper systematically reviewed the occurrence characteristics and regulations of wheat scab, and systematically analyzed the reasons affecting the occurrence of wheat scab in northeast Sichuan, and summarized the green prevention and control techniques of wheat scab from the aspects of breeding resistant varieties, healthy cultivation, field management, precise and scientific application of chemicals, etc.
