不同基质对山茶花扦插生长的影响

为研究不同扦插基质对山茶花扦插生长的影响，选择4种不同基质：S1（河沙）、基质S2（黄心土）、基质S3（黄心土∶河沙=1∶1）、基质S4（黄心土∶河沙=2∶1）对山茶花进行对比扦插试验。结果表明：4种不同基质的扦插苗生根率、苗高、新梢长之间存在着极显著差异。基质S4对扦插苗生根效果最好，扦插苗鲜重与根系生物量最大，平均总鲜重达到2.41 g/株；基质S2对扦插苗生长最佳，地上干重最大，平均达到0.95 g/株。因此，茶花扦插育苗的适宜基质为S4，其次为基质S2，建议在生产上推广应用。

Effects of Different Substrate on the Growth of Cutting of Camellia japonica

In order to study the effect of different substrate on the cutting growth of Camellia japonica,four different substrate S 1（river sand）,S 2（yellow soil）,S 3（yellow soil：river sand =1：1） and S 4（yellow soil：river sand =2：1） were selected for cutting contrast test.The results showed that：the effect of S 4 on cutting rooting was best,which had great fresh weight and biomass,and the average fresh weight reached 2.41 g/plant;S 2 was best for growing of cutting seedlings,and it had great dry weight,the average reached 0.95 g/plant.Therefore,the suitable substrate for cutting of Camellia japonica was S 4,followed by substrate S 2,and they were suggested in production application.
