雪松在济南适生,观赏价值较高。但过去,每年要到青岛、南京等地购买苗木,由于远途运输及环境的变化,成活率很低,损失巨大。我圃于七六年春建立科研小组,专门进行常绿树的扦插试验,几年来取得一些成绩,其中雪松扦插成活率达到90％以上。育成雪松苗几千株。现将情况汇报于下:一、扦插苗床的制做:扦插床为永久性砖砌高床。东西走向,高度50厘米,净宽100厘米,插床底部用砖平铺,砖下有通风孔道,砖上铺鸡卵石一层10厘米,上面为黄沙(稍细)作扦插基质,厚度约20厘米左右,沙面距插床顶沿,还有几公分的距离。以蛭石为扦 Cedar suitable for living in Jinan, ornamental value higher. But in the past, every year to Qingdao, Nanjing and other places to buy seedlings, due to changes in long-distance transport and the environment, the survival rate is very low, a huge loss. I nursery in the spring of 1976 to establish a scientific research team, specializing in cuttings of evergreen trees in the past few years to achieve some results, including cedar cutting survival rate of more than 90%. Bred into several thousands of cedar seedlings. Now the situation reported in the next: First, the production of cutting seedbed: cutting bed is a permanent brick high bed. East and west, height 50 cm, net width 100 cm, the bottom of the bed with brick tile, ventilation brick under the brick, brick layer of cobble top layer of 10 cm above the yellow sand (slightly thin) for the cutting substrate thickness of about 20 Centimeter, sand surface from the top of the bed, there are a few centimeters distance.
