在植病流行学研究和测报中,尤其是在病害流行的模拟研究中,叶面结露时间是个相当重要的因子。它的长短直接决定叶面病原真菌孢子萌发和侵入的数量多少,从而决定真菌性叶斑病侵染概率值的高低;对细菌性叶斑病的发生也有较大影响;因此,准确掌握叶面结露时间长短对病害预测具有重大意义。 In phytopathogenic research and forecasting, especially in the simulation of disease epidemics, leaf dew condensation time is a very important factor. Its length directly determines the number of spore germination and invasion of pathogenic fungi spores to determine the level of fungal leaf spot infection probability value; the occurrence of bacterial leaf spot also have a greater impact; therefore, accurately grasp the leaf surface The length of dew condensation is of great significance to disease prediction.
