- 摘要:
- 研究不同基质材料、不同激素浓度、不同年龄插穗处理对秤锤树硬枝插穗扦插生根的影响。结果表明:全光雾试验条件下,植物生长调节剂BA、基质、树龄对扦插成活率均有影响,幼龄树木、混合基质和高浓度BA处理对秤锤树硬枝扦插最为有利。5 a生硬枝作插穗,用1 000 mg/L的BA速蘸插条基部,扦插在河沙∶珍珠岩∶泥炭=1∶2∶2的混合基质中,扦插生根率最高,可达90.34%。
- Abstract:
- The different effects of base material,hormones concentration and cutting age treatments on spraying scion cuttage of Sinojackia xylocarpa Hu were studied.The results showed that the effect of plant growth regulator BA,base material and mother tree age on survival rate of Sinojackia xylocarpa Hu cuttings were influenced.Under the test condition of natural illumination and automatic intermittent spraying,the younger tree,mixed materials and high concentration BA were favorable for spraying scion cuttage of Sinojackia xylocarpa Hu.The rooting percentage were higher than others when the cuttings were tachy-dipped by 1 000 mg/L BA and then cutted in the composite base material comp rised of sand∶perlite∶peat=1∶2∶2,the scion cuttings of the former year from mother tree aged 5 a could reach the best rooting percentage(90.34%).
