【摘要】 通过1986-1990年对小麦白粉病的系统观测,应用灰色系统理论,分析了小麦白粉病流行与气象因素变化的动态关系,明确了雨湿条件是影响小麦白粉病的主要因素。其次是最低温度等温度指标,光照因素影响较小。
【Abstract】 By observing system wheat powdery mildew from 1986 to 1990, applying grey system theory , The development relation between wheat powdery mildew and atmospheric condition was analyzed. The paper applied the rain and humidity is the main factor of influencing wheat powder mildew, the second is the lowest temperature , the last is illamination.
