一、材料与方法插穗的剪取在宝清县头道岗林场,取二年生幼苗条;20年生大树的萌条、徒长枝、花枝;同一棵树不同部位(冠上、中、下)的花枝;同一棵树不同时间的营养枝。插穗的长度为15—20厘米,其上端留有芽苞,下端剪成斜的刀口。插穗的处理为探索激素的种类、浓度、浸泡时间对生根影响的规律,1978年用吲哚乙酸、吲哚丁酸、萘乙酸,三者的浓度分别为100PPm、200PPm、250PPm,浸泡时间为24小时,药液温度常温。
First, the material and methods cutting cuttings in Baoting County Tau Dao Gang farm, take two years seedlings; 20-year-old tree sprout, leggy branches, flowering branches; the same tree in different parts (top, middle and lower) Flowering branch; branch of the same tree at different times. Cuttings of 15-20 cm in length, leaving the bud bud at the top, the bottom cut into a ramp incision. In order to explore the rule of the type, concentration and soaking time of hormones on rooting, in 1978, indole acetic acid, indole butyric acid and naphthalene acetic acid were used. The concentrations of the three were 100 ppm, 200 ppm and 250 ppm, respectively, and the soaking time was 24 Hours, liquid temperature at room temperature.
