预测稻瘟发生,进行空中病菌孢子活动情况调查时,一般都用载片涂油捕捉孢子,来计算一定面积内的孢子量,分析孢子活动和发病的关系。由于稻瘟病菌的分生孢子没有颜色,在显微镜下观察识别比较困难,所以往往容易检漏。为了克服这种缺点,我们参阅文献,利用孢子能被染色的特点,进行显微镜下的检查。这个方法简而易行,不仅容易区别稻瘟的孢子,且 Predict the occurrence of rice blast, airborne spores activity survey, the general use of oil coated capture slide spores, to calculate the amount of spores in a certain area, analysis of the relationship between spore activity and incidence. Due to the absence of color conidia of Magnaporthe grisea, it is often easier to detect leaks when viewed under a microscope. In order to overcome this disadvantage, we refer to the literature, the use of spores can be stained characteristics, microscopic examination. This method is simple and easy, not only easy to distinguish the spores of rice blast, and
