Abstract:: Taking Rhododendron as the test material,litter leaves∶soil=1∶1 for the cultivation medium,using the method of difference analysis,the effects of different doses of citric acid,black sail,sulphur and peat on the growth indexes such as height,canopy,leaf area and chlorophyll of Rhododendron were studied,in order to find suitable pH regulator for Rhododendron cultivation.The results showed that plant height,crown amplitude,leaf area of A4 (peat 60%),A10 (ferrous sulfate 10 kg?m^-3) and A11 (ferrous sulfate 15 kg?m^-3) matrix were the best,the mean of chlorophyll was better;secondly,the plant height,canopy,chlorophyll and leaf area of A3,A6,A7,A9 and A12 matrix were better,and the plant height,crown amplitude,leaf area and chlorophyll of A2,A5,A8,A13 and A14 matrix were better;plant height,crown amplitude,the leaf area and chlorophyll of A15 and A16 matrix were the worst.The cost of A4,A10,A11 and A12 matrix were all higher;A3 group added peat 2,A6,A7 group respectively add citric acid 2 kg?m^-3,4 kg?m^-3,A9 experimental group added ferrous sulfate 5 kg?m^-3,were relatively low cost, Rhododendron various biomass traits,could be used in container seedling production.
