| 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 between the disease occurrence and the sowing time. The damage of Pythium remarkably increased when sowing in humid hot season. The damage was remarkably reduced by combining the following measures: sowing in the last 10 days in October to the first 10 days of March, seeding soaking in 1% liquid metalaxyl, less density and spraying metalaxyl of phosethyl-Al in humid hot season. |
