摘要
采用不同的基质配方和激素配方处理东方杉嫩枝插穗。扦插试验结果表明:基质配方J4(泥炭∶珍珠岩=1∶1(V∶V))和激素配方M7(NAA∶IBA=1∶1(m∶m))500 mg/L处理比较适合东方杉嫩枝扦插繁殖,扦插成活率达86%。不同基质配方处理和不同激素配方处理均对扦插成活率影响达到极显著性水平,其中J4基质配方和M7激素配方能使插穗平均生根率达最高,分别为67.625%和70.0%。
The effects of different kinds of mediums and different hormones on survival rate of softwood cuttings of × Taxodiomeria ＇ Peizhongii＇ were studied. The experimental results showed that medium J4 （ peat/perlite （ 1： 1 ） ） and M7 （ NAA/ IBA （ 1：1 ） ,500 mg/L） were better, the survival rate was 86.0%. Different kinds of mediums and hormones had significant effect on survival rate of cuttings. J4 medium treatment was the best, the survival rate was 67. 625%. M7 hormone treatments was the best, .the survival rate was 70.0%.
