| 摘 要： | 目的]筛选绣球的最佳扦插基质。方法]以珍珠岩、蛭石和泥炭为原料，配制7种不同的扦插基质：①珍珠岩；②蛭石；③泥炭；④珍珠岩∶蛭石=1∶1；⑤珍珠岩∶泥炭=1∶1；⑥蛭石∶泥炭=1∶1；⑦珍珠岩：蛭石∶泥炭=1∶1∶1，比较不同基质中绣球插穗的生根率、生根条数和生根长度。结果]处理⑦、⑥、④插穗的生根率均为100%，显著高于其他处理；处理⑥插穗的平均生根条数（50.83条）显著多于其他处理；处理⑦插穗根最长（4.17 mm），且与其他处理差异极显著（P〈0.01），处理6插穗根最短（2.03 mm）；处理②插穗的生根率最低，平均生根条数最少。结论]泥炭可促进绣球插穗生根，而珍珠岩∶蛭石∶泥炭=1∶1∶1的基质可促进绣球插穗根的伸长生长。

| Abstract: | Objective] The study was to screen the optimum cutting substrate for hydrangea L..Method] With perlite,vermiculite and peat as the materials,7 kinds of cutting substrates such as ① perlite;② vermiculite;③ peat;④ perlite:vermiculite =1∶ 1;⑤ perlite:peat=1∶ 1;⑥ vermiculite∶ peat=1∶ 1;⑦ perlite∶ vermiculite∶ peat=1∶ 1∶ 1 were prepared,and the rooting rate,number and length of roots of the cuttings in different substrates were compared.Result] The rooting rates of cuttings in treatments of ⑦,⑥,④ all reached 100%,being significantly higher than those in other treatments.The number of roots of cuttings in treatment ⑥(50.83 roots.) was significantly more than those in other treatments.The length of roots of cuttings in treatment ⑦ was the longest,being very significantly different with that in other treatments.The number of roots of cuttings in treatment ② was the least with the lowest rooting rate.Conclusion] The peat could promote rooting of cuttings of Hydrangea L.,and the substrates that perlite∶ vermiculite∶ peat=1∶ 1∶ 1could promote the elongation growth of the roots of cuttings of Hydrangea L.. |
