通过试验表明:GGR生根粉对光箨绿竹Dendrocalamopsisatrovirens的秆芽萌发数量有显著影响,其中25mg/L的处理效果最好,比对照样方发笋数增加177.78%。GGR对光箨绿竹47d时的地径没有显著影响,对80d时的地径和秆高、134d时的地径和秆高均有极显著影响。处理浓度30mg/L最好,25mg/L次之。因此用GGR生根粉对光箨绿竹进行辅助快繁育苗效果明显,处理浓度宜在25～30mg/L之间。
The results showed that the rooting powder of GGR had significant effects on the germination of stalks of Dendrocalamopsis atrovirens. Among them, 25mg / L had the best treatment effect, which increased 177.78% more than the control. GGR had no significant effect on the ground diameter of Buxuspora at 47d, and had a significant effect on the ground diameter and stalk height at 80d and the ground diameter and stalk height at 134d. The best concentration of 30mg / L, followed by 25mg / L. Therefore, the use of GGR rooting powder Guangzhu green bamboo assisted rapid propagation effect is obvious, the treatment concentration should be between 25 ~ 30mg / L.
