圆柏芽枯病是大连地区圆柏最主要的病害,80年代开始在大连市林业科研所苗圃和劳动公园成灾,到90年代初已传播蔓延到7个县(市)区,从1年生小苗到多年生幼树均能发病。病原菌为壳小圆孢属(Coniothyriumsp.)的真菌,在病叶上越冬,翌年5月中旬开始侵染发病,6~9月为发病盛期,9月份停止发病。发病除和树种及树龄有关外,还同温度、湿度、降雨量、地形、地势、通风、透光密切相关。据室内抑菌和大田防治试验,以波美1度石硫合剂防治效果为最好,经防治病树普遍恢复了生机,年平均高生长达40cm左右。
Jun Bai blight is the most important disease of Sabina vulgaris in Dalian area. In the 1980s, he began to suffer disaster in nurseries and labor parks of Dalian Forestry Research Institute. In the early 1990s, it spread to 7 counties (cities) Seedlings to perennial young trees can attack. The pathogen is a fungus of the genus Coniothyrium sp., Which overwintered in the diseased leaves. Infestation began in mid-May of the next year, and peaked from June to September, with onset in September. In addition to the incidence and tree species and age, but also with the temperature, humidity, rainfall, topography, topography, ventilation, light is closely related. According to indoor antibacterial and field control trials to Baume 1 degree stone sulfur mixture to control the best, by the general rehabilitation of the disease-resistant tree vitality, the average annual high growth of 40cm or so.
