The carbonized rice husk and fly ash obtained from waste were mixed with turf， fine sand and vermiculite in different proportions to be used as the seedling substrate of Lonicera japonica in order to study the impacts of composite substrates on cutting seedings of Lonicera japonica.The results showed that the two groups composite substrates compounded by carbonized rice husk， turf， fine sand and vermiculite， its bulk density was between 0.28 ～ 0.63 g/cm3， the total porosity was between 69.51% ～ 84.90%， the pH was between 5.60 ～ 7.50， and its physical and chemical properties were in a suitable range for Lonicera japonica cutting seedlings.Correlation analysis showed that total porosity and available phosphorus，available potassium and alkali hydrolyzable nitrogen content in the composite substrate were significantly positively correlated with the plant height， rooting number， longest root， leaf number and SPAD growth indicators of Lonicera japonica cutting seedlings( P<0.01)，the bulk density had a significant negative correlation with the growth indicators of Lonicera japonica cutting seedlings( P<0.01)， this indicated that the effect of composite substrate on the growth and development of Lonicera japonica was related to the proportion of substrate mixing.In brief， turf: fine sand: carbonized rice hull( 1∶1∶4) and turf: fine sand: vermiculite: carbonized rice hull( 1∶1∶1∶4)were recommended as the substrate formula for Lonicera japonia cutting seedlings.
