1.建造插床建宽1.2米(长度根据插穗数量而定)、高80厘米的封闭式塑料小拱棚,上覆80%的遮阳网。基质分别由清水河沙、炉渣加沙、炉渣加土、土加沙、上沙下土、疏松土6种物质组成,用孔径0.5×0.5平方厘米的立铁筛,筛去杂物和杂质,床面喷施0.1%的多菌灵和0.2%的辛硫磷杀菌灭虫。2.处理插穗每年5～6月、9～10月,从5年生日香桂上剪取当年生长健壮的半木质化枝条作插穗,留一对叶芽即可,节下最好留0.5厘米以上的茎段,便于扦插。将叶片剪去一半,基部用利刃削平,株行距4.5×6厘米。插前分别用50～1000ppmABT 1号生根粉速蘸30秒或浸泡插穗基部0.5厘米处0.5～12小时,即插入插床。插后据天气情况进行喷雾,以叶表面湿润不滴水为度,每天3～4次,以上沙下土的沙表面显白为度。实验采用随机区组,重复3次,每种处理50株,用竹签做好标记,隔3天观察一次愈伤和根系生长情况,记录生根长度、条数、生根率(见表1)。
1. Construction of the slotted bed 1.2 meters in width (the length depends on the number of cuttings), 80 cm in height, closed plastic shed, covered 80% of the shade net. The matrix was composed of six kinds of materials, namely, clear water river sand, slag Gaza, slag plus soil, soil Gaza, sand upper and lower soil, and loose soil. The sieve was screened for impurities and impurities with a vertical iron sieve with an aperture of 0.5 × 0.5 cm 2. Spraying 0.1% carbendazim and 0.2% phoxim sterilization pest control. 2. Processing Cuttings May to June each year, September to October, cut from the 5-year birthday fragrant Gui the robust growth of semi-lignified branches for cuttings, leaving a pair of leaf buds, the best section to stay 0.5 cm above The stem section, easy cutting. The leaves cut in half, the base trimmed with sharp edges, spacing of 4.5 × 6 cm. Insert before use 50 ~ 1000ppmABT 1 rooting powder speed dip 30 seconds or soaking the base 0.5 cm at 0.5 to 12 hours, which is inserted into the slot. Insert according to the weather conditions for the spray to leaf surface moist drip for the degree, 3 to 4 times a day, above the surface of the sand under the sandy soil for the degree of clarity. A randomized block was used in the experiment. The experiment was repeated 3 times. Each strain was treated 50 times and labeled with bamboo sticks. The callus and root growth were observed every 3 days. The rooting length, number and rooting rate were recorded (Table 1).
