不同基质和扦插处理对4种景天扦插生根的影响
|
摘要
为筛选4种景天的扦插繁殖适宜方法,对引种的中华景天、金叶佛甲草、米粒景天和银边佛甲草在不同基质及插穗处理的生根情况进行试验研究。结果表明:较适合的生根基质:中华景天、米粒景天和金叶佛甲草是珍珠岩+草炭土(1∶1),银边佛甲草是珍珠岩+蛭石(1∶1)。中华景天、米粒景天和金叶佛甲草最适扦插部位均为茎尖部。中华景天最适扦插方式为竖插,米粒景天为横插不刻伤,金叶佛甲草为横插不刻伤。扦插的茎段部位和处理方式对中华景天、米粒景天、金叶佛甲草插穗生根数量和生根长度影响显著,对中华景天和米粒景天的生长高度影响不显著,对金叶佛甲草的生长高度影响显著。
The rooting situation of Sedumpolytrichoides,Sedum ‘Mili',Sedum lineare cv.‘Jin Ye'and Sedum lineare ‘Variegatum'cuttings cultured in different substrates and under different cutting treatment was studied to screen the optimal cutting propagation method for four Sedumspecies.Result:The optimal rooting substrate of S.polytrichoides,S.‘Mili'and S.lineare cv.‘Jin Ye'cuttings is perlite+turfy soil(1∶1)and the optimal rooting substrate of S.lineare ‘Variegatum'is perlite +vermiculite(1∶1).The optimal cutting part of S.polytrichoides,S.‘Mili'and S.lineare cv.‘Jin Ye'is a stem tip.The optimal cutting pattern of S.polytrichoides,S.‘Mili'and S.lineare cv.‘Jin Ye'is vertical cutting,buried cutting without a cut and buried cutting without a cut respectively.The cutting stem position and treatment pattern have the significant effect on rooting number and rooting length of S.polytrichoides,S.Mili'and S.lineare cv.‘Jin Ye'cuttings and no significant effect on height of S.polytrichoides and S.‘Mili'cuttings and no significant effect on height of S.Lineare cv.‘Jin Ye'cuttings.
