1980年春,我场从南京中山植物园获得日本友人赠送的榉树种子半市斤,因播种迟,出苗不多,1981年春,我们利用修剪苗木得到的叉枝做插穗,进行扦插育苗试验,基本获得成功.现报道如下:一、材料和方法1.供试材料 日本榉树一年生实生苗叉枝、侧枝.枝条直径0.3—1.0厘米.2.操作程序 用剪枝剪将试材剪成长8—10厘米的插穗,每枝插穗保留4—5个芽.插穗用500PPm萘乙酸粉剂处理,并立即插入室外预先准备好的(石至)石插床中.插入深度以能见到插穗最上端一个芽为限.插床用竹子搭拱形架,拱架中心离床面60厘米左右,上覆农用塑料薄膜,内挂温度计1支.
In the spring of 1980, we obtained half of the beech seeds donated by Japanese friends from the Zhongshan Botanical Garden in Nanjing. Due to the late sowing and the sprout emergence, in the spring of 1981, we used the pruning branches of pruning seedlings to do cuttings, Success. Now reported as follows: First, the material and methods 1 for the test material annual seedlings of Japan beech tree branches, collateral. Branches 0.3-1.0 cm in diameter .2. Procedure Pruning shear test material grow 8-10 Cm cuttings with 4-5 buds per cuttings Cuttings are treated with 500 PPm naphthaleneacetic acid powder and immediately inserted into a pre-prepared (rock-to-stone) cuttings bed outdoors Inserted into the depth to see the top of a cuttings as Limited. Insert bed with bamboo arched frame, the center of the arch from the bed about 60 cm, covered with agricultural plastic film, a thermometer attached.
