摘要
稻瘟病(PyriculariaoryzaeCavara)是危害水稻生产的一个主要病害,了解稻瘟病菌孢子生活史中的影响因素,监测稻瘟病菌的时空分布动态,对于预测预报病情的发生,确定最佳的防治时机和指导田间防治有重要的意义。本文讨论了影响孢子传播的因素和孢子捕捉的方法,并就玻片法捕捉孢子的方法进行了初步的研究。
The rice blast which cuased by Pyricularia oryzae Cavara is a serious disease in the rice production. It has an import meaning to know which factors affect the Pyricularia oryzae Cavara spore in the life cycle and how to monitor the spatial and temporal dynamics of spore, so we can predict and forecast the disease occurrence and decide the suitable time to spray pesticide ,and instruct the strategy of prevention and cure in fields. In this paper, we discussed the influencing factor of spore distribution and the spore trapping methods in using, and report some primary research result of spore trapping methods using glass microscope slide.
