龙爪槐(Sophora japonica Linn.var.pendula Loud.)高不盈丈,枝条纷披下垂,是较好的观尝树种之一。用芽接繁殖成形慢,一般劈接或切接剖面裸露,水份散失快,成活率低。笔者于1990年春对龙爪槐进行嫁接套袋试验,效果极为显著。 1 砧木及接穗 以国槐作砧木,干粗2.0～5.0厘米,干高截留180～200厘米,嫁接部位剖面1.5～3.0厘米。接穗选取龙爪槐上年健壮新生枝,剪截长度4～8厘米,粗度0.3～1.0厘米,留有2～3个侧芽。
Sophora japonica (Sophora japonica Linn.var.pendula Loud.) High non-profit Zhang, branches drooping, is one of the better viewing species. Sprouting propagation with slow shape, the general split or cut access section exposed, fast water loss, low survival rate. The author in the spring of 1990 dragon claw bagging test, the effect is extremely significant. 1 rootstock and scion Sophora japonica rootstock, dry coarse 2.0 to 5.0 cm, dry high cut 180 to 200 cm, the grafted section of 1.5 to 3.0 cm. Scion selection Longjiaohuai robust new branches last year, cut length 4 ~ 8 cm, thickness 0.3 ~ 1.0 cm, leaving 2 to 3 lateral buds.
