橡胶白粉病是一种气传病害,研究其空中孢子量的变化规律,可使我们了解孢子的传播,进而探讨利用空中孢子量预测病害的可能性,改进目前的测报方法。气传病害的孢子捕捉,早在1954年,英人Hirst就设计了一种吸气式的捕孢器。1972年Beerker作了改进,可以连续取样一个星期。日人研制了旋转式捕孢器,近年英、美学者又设计了一些新型的捕孢器,认为可以提高捕捉效率。利用捕孢器取样以预测病害的发生,在茶饼病、稻瘟病上取得了 Rubber powdery mildew is a kind of airborne disease. Studying the variation rule of the amount of aerial spore can make us understand the spread of spore, and then explore the possibility of using aerial spore quantity to predict the disease and improve the current method of forecasting. Gas-borne disease spore capture, as early as 1954, the British Hirst designed a suction-type spore catcher. Beerker made an improvement in 1972 and could sample continuously for a week. Japanese developed rotary spore catcher, in recent years, Britain, estheticians have designed some new spore catchers, that can improve the capture efficiency. Sampling with a spore-nephelometer to predict the occurrence of the disease was made on the tea cake disease and the rice blast
