Effect of Different Substrate Ratios on the Growth of Container Seedlings of Cunninghamia lanceolata Cuttings
In 2023,this paper conducted two substrate ratios for Cunninghamia lanceolata cutting seedling cultiva-tion experiments.The results indicate that the seedling height,ground diameter,height to diameter ratio,total bio-mass,root to shoot ratio,and QI values of substrate A(70％peat+20％perlite+10％husk)are 22.8 cm,3.3 mm,65.9,3.1g,0.34,and 0.045,respectively;The B substrate ratio(60％peat+20％perlite+10％husk+10％cedar bark)has seedling height,ground diameter,height to diameter ratio,total biomass,root to shoot ratio,and QI val-ues of 20.7cm,3.8 mm,54.1,3.5 g,0.31,and 0.059,respectively.There was no significant difference in seedling height,total biomass,root to shoot ratio,and QI value between the two substrate ratios(P＞0.05).There were significant differences(P＜0.05)between ground diameters and height to diameter ratios.
