本文研究了降雨对空气中浮游孢子携落率的计算问题,提出了根据降雨量(M)、持续降雨时间(H)来计算降雨对空气中浮游孢子携落率(Y)的公式;令D=1.24(M/H)~(0.182),则Y=1-EXP(-1.5M/D)。根据部分资料估计了真菌气传病害的空中浮游孢子与植物叶表附着孢子的比率(R)约为1～5:1,由此可推算因降雨对空气中浮游孢子的携落作用和对植物表面附着孢子的冲刷作用(冲刷率为W)的综合结果,使植物表面附着孢子数变为原来的(1+R·Y)(1-W)倍。
In this paper, the calculation of the rate of zooplankton in the air by rainfall was studied. The formula for calculating the rate of zooplankton spores in the air by rainfall (M) and continuous rainfall time (H) was proposed. Let D = 1.24 (M / H) ~ (0.182), Y = 1-EXP (-1.5M / D). According to the partial data, the ratio (R) of airborne zoospores to the leaf spore attached to fungi is estimated to be about 1 to 5: 1. Therefore, it can be inferred that the effect of rainfall on airborne zoospore and the effect on plant The combined effect of surface-attached spore scouring (washout rate W) results in a (1 + R · Y) (1-W) fold increase in the number of spores attached to the plant surface.
