| 摘 要： | 云杉灰霉病由灰葡萄孢(Botrytis cinerea)引起,分布于新疆阜康、乌鲁木齐、呼图壁、玛纳斯、沙湾、霍城、伊宁、察布查尔、新源、巩留等林区,主要发生在苗圃,生长季节发生危害,尤以温棚育苗发病严重,寄主除本地的天山云杉(Piceaschrenkiana var. tianshanica)、雪岭云杉(P.schren-kiana)外,还有引种的青海云杉(P.crassifolia)、川西云杉(P.likiangensis var. balfouriana)。病原菌菌落在PDA培养基上以22℃生长最佳,第6天产生附着孢,第7天产生菌核,第10天产生分生孢子。菌核在4~28℃均能萌发,22℃萌发速度最快,1 d菌核萌发率即达63.3%。大田条件下,在新梢生长期(5月下旬至6月下旬)喷施25%多菌灵500~800倍液;在温棚育苗条件下,重病区每年喷药2~3次,每次间隔7~10 d,每天定时2次揭开棚膜距地面1 m,通风降低空气湿度,可消除云杉灰霉病危害。

| Abstract: | Grey mould of spruce results from Botrytis cinerea.It was distributed widely in the forests within Xinjiang,such as Fukang,Urumqi,Hutubi,Manas,Shawan,Huocheng,Yining,Chabuchaer,Xinyuan,Gongliu.It mainly occurs in the nursery in the growing season,particularly in the greenhouse.The hosts include local tree species,such as Picea schrenkiana var.tianshanica,P.schrenkiana,as well as introduced species,such as P.crassifolia,P.likiangensis var.balfourianai.It was found that the optimal temperature for the colony ... |
