【摘要】 本文根据不同类型麦田小气候的差异修改了已有的白粉病流行的模拟模型,模拟和预测了不同种植密度麦田白粉病的流行情况。结果表明:当麦田种植密度大时,其小气候相对湿度较高而温度则相对较低,这类麦田的白粉病流行较快;反之,相对湿度较低而温度则相应较高,这类麦田白粉病流行则较慢。更多还原

【Abstract】 The developed simulation models of powdery mildew (Erysiphe graminis DC. f. sp. tritici). were modified based on wheat field microclimate. The simulation models were used to simulate and predict the powdery mildew epidemic of three types of wheat density in the field. The results showed that the epidemic of the powdery mildew was faster when the density of planting was higher and otherwise, the epidemic was slower.更多还原
