雪松常绿乔木,是世界上著名观赏树种之一,我国长江中下游一带生长良好,近几年来北方的一些城市绿化中也广泛栽培。雪松树冠圆锥形,主干挺直,侧枝向四周展开,姿态雄伟,生长迅速,适应性强,是很好的绿化美化树种。但雪松小苗性喜沙壤土,PH值中性偏酸性,在我国北方地区育苗成活率低,因此,北方雪松苗木大多从南方调进。自1986年开始,我们结合北方的气候和环境条件以及雪松育苗的技术特性,利用塑料棚进行了雪松的扦插育苗,多次试验中,成活率均达到60—80％,通过3年试验,总结出一些育苗方法,简述如下一、选地设棚在院内或其它空闲地设一小棚,棚内设 Cedar evergreen trees, is one of the world famous ornamental tree species, growing well in the middle and lower reaches of the Yangtze River in our country, in recent years a number of urban greening in the north are also widely cultivated. Cedar crown conical, trunk upright, collateral spread to the surrounding, majestic, rapid growth, adaptability, is a good afforestation tree species. However, the cedar saplings lovable sandy loam, PH neutral acidic, low survival rate of nursery in northern China, therefore, most of the northern cedar seedlings transferred from the south. Since 1986, we have combined the climate and environmental conditions in the North with the technical characteristics of cedar nursery stock and used the plastic shed to carry out the cutting propagation of cedar. In many trials, the survival rate reached 60-80%. After 3 years of trial, we concluded A number of nursery methods, outlined as follows one, choose to set up shed in the hospital or other free to set up a shed, shed set
