A study on cutting medium for the softwood of Lagerstroemia indica
YAO Xiangming
Abstract：In order to study the effect of matrix ratio on the quality of rooting for the softwood of Lagerstroemia indica.10 kinds of substrate preparation cuttage experiment with crape myrtle peat,sand,vermiculite,coir and perlite.The results show that the rooting rate,root number,root length and partial root rate of rooting characters because of the different matrix formuG la is different and there are significant differences.Substrate composition of peat (50%)and perlite (50%),Lagerstroemia inG dica cuttings of highest average rooting rate was 97.64%;Substrate composition of peat (50%)+ cocopeat (50%),the averG age number of rooting cuttings of crape myrtle up,4.04;substrate composition of peat (100%),the average of the longest root crape myrtle cuttings length,5.95cm;medium was vermiculite (50%)+ cocopeat (50%),the average partial root cuttings of crape myrtle was the lowest,16.42%.Sequence matrix associated with rooting rate is peat> perlite> vermiculite> river sand> coconut chaff;The number of article and rooting relational sequence is perlite > peat > coconut chaff> vermiculite >river sand;The correlation between rooting length and rooting length is peat > perlite> coconut chaff >river sand > vermiculite;Associated with partial root rate is vermiculite >river sand > perlite> coconut chaff >peat.Select peat and perlite in a reaG sonable proportion matrix by Lagerstroemia indica softwood can make a good cutting effect.
