龙柏属柏科,桧属,为常绿乔木,系圆柏的变种。鳞片叶密生,枝条稠密,树冠呈狭圆筒形,树态瘦削直耸,侧枝螺旋状向上抱合,别具一格,是绿化庭园的优良树种。但因种源少,扦插育苗不易生根,嫁接育苗数量有限,繁殖速度缓慢,不能满足绿化事业的需要。为了提高扦插成活率,1984年,我们在塑料温棚内进行了扦插育苗试验,取得初步效果,现简报如下。1.试验内容及材料试验分扦插入土深度(3、10厘米)、插穗枝叶去留(全部保留、下部10厘米内剪
Cypress is Cypress, Juniper is a evergreen tree, Department of Sabina varieties. Scales leafy habitat, thick branches, the crown was narrow cylinder, tree-shaped straight thin straight, collateral spiral upward spiral, unique, is an excellent tree species of green garden. However, due to less provenance, cutting seedling is not easy to root, grafting a limited number of seedlings, propagation rate is slow, can not meet the needs of greening. In order to improve the survival rate of cuttings, in 1984, we carried out cuttage nursery in plastic greenhouse experiment, and achieved initial results, are summarized as follows. 1. Test content and material test points cut into the soil depth (3,10 cm), cuttings leaves to leave (all retained, the lower 10 cm shears
