摘 要 ：研究了冷季型草坪腐霉猝倒和叶腐病发生规律和防治技术，结果表明，苗期处于20-30℃、持续高温、-必植（3-5株/cm^2）等条件下最有利于腐霉病菌的侵害；腐霉猝倒和叶腐病发生同草坪播种期关系密切，湿热季节（4月上旬至8月下旬）播种严重受害，雨后积水可导致毁坪，防治该病要改善草坪基因条件，在上年10月下旬至当年3月上旬播种，用25%甲霜灵WP100倍液浸种，适当稀播，发病季节多次喷施甲霜灵或乙磷铝等针对性农药。

Abstract:The results of experiment and field survey showed that the most favorable conditions for Pythium infection at seedling stage of cool-season turfgrass were 20-30, continuous high humidity and close planting (3-5 seedlings/cm2). There was a closer relation
