不同扦插基质对榉树根系生长的影响

Effect of Different Cutting Medias on Root Growing of Zelkova schneideriana

为探讨黄山地区榉树最佳扦插基质,选取黄心土、河沙、蛭石为基质,研究了榉树硬枝在上述扦插基质上的生长情况。结果表明:不同基质对榉树扦插成活率影响较小,但蛭石作为扦插基质时,根条数、根长和根重均大于其他2种基质,有利于根系的生长,从而可能影响到移栽成活。

In order to find the optimum cutting media,the paper chose yellow soil,sand from river and vermiculite as medias to study survival rate of Zelkova schneideriana.The results showed that the survival rate of cuttings were not significant difference among three medias,but cuttings had more number of roots,longer root and larger weigh of root in vermiculite compared with other medias,this could be in favour of survival rate when they were transplanted.
