不同基质和激素处理对海南油茶扦插育苗的影响

Effects of different substrates and hormone treatments on Camellia oleifera cutting seedling in Hainan

不同基质和激素处理对海南油茶扦插育苗试验结果表明,以红土为基质,NAA100mg/L浸泡处理6h是提高扦插成活率的最优处理组合,成活率大于74.0%,效果最好。具体看,混合土为基质,IBA300mg/L浸泡处理4h,平均根数大于24.0条/株,是促进扦插生根的最优处理方法。以混合土为基质,NAA100mg/L浸泡处理6h促进根长的效果最佳,处理插穗的平均根长为6.2cm。

Camellia oleifera cutting seedling test were carried ments, the results showed that the laterite matrix, NAA 1 00mg/L out by different substrates and hormone treat- soaking 6h is the optimal treatment combina- tions to improve the survival rate of cuttings, the survival rate is greater than 74.0%, the effect is best. Specifi- cally, the mixed soil matrix, IBA300mg/L soaking 4h, average number of roots greater than 24, is the best ap- proach to promote rooting cuttings. The effect of mixed soil matrix,NAA100mg/L soaking 6h,is the best to promote root length, average root length treated cuttings is 6.2cm.
