| 摘 要： | １９９７～１９９８年对宁波、鄞县、杭州等１１个县、市、区约１２万ｈｍ２ 的冷季型草坪进行调查，结果表明：引起冷季型草坪成团枯死的主要病原菌有６种腐霉菌、４种镰刀菌，３种丝核菌和草叶瘟菌；当年新播草坪大量枯死主要是由腐霉菌引起的幼苗猝倒和茎叶腐烂所致，二、三年生草坪上以镰刀菌和丝核菌引起的枯草团为主。腐霉菌的为害与草的播种期密切相关，从３月上旬至６月上旬，病害为害程度随播种期的推迟而急剧加重，上年１０月下旬以后至当年３月上旬之前播种可减轻腐霉菌的为害

| Abstract: | Investigation results showed that six Pythium, four Fusarium and three Rhizoctonia were main pathogenic diseases of cool season lawn in Zhejiang province in 1997 and 1998.Pythium was main pathogeny,resulting in the wither and rot of stem and leaf in newly planting lawn.These was a closer relation between harm of Pythium and sowing time,and the harm of Pythium rapidly increased as the sowing time was put off from March 1 to June 10. The harm can be markedly reduced while in October 1 to March 10 of next year. Fusarium and Rhizoctonic were main pathogenic species in cool season lawn of 2～3 yearsgrowing period. |
