Abstract: Through investigations on the seedling growth in five permanent and two temporary nurseries,an analysis was made on the soil nutrition condition.The results indicate that the condition of the soil nutrient in the nurseries which had been cultivated with seedlings in 6 successive years were 2～3 times lower than that in the soil of the wasteland nearby.The seedlings of Burretiodendron hsienmu and Garcinia paucinervis grow well in the nurseries at lower altitude with lime soil.The seedlings of Tectona grandis,Michelia macclurei and Gmelina arborea are suitable to be cultivated in the nurseries at lower altitude with neutral soil.Paramichelia baillonii,Homalium hainanense,Illicium verum,Mytilaria laosensis,Castanopsis hystrixand Pinus massoniana grow well at the higher altitude nurseries with acid soil.The results after fertilization for seedlings show,that the fertilizer rate ofN24P0K20 is the best combination for the seedlings of broad leaf trees.The height,root diameter,above ground and underground biomass of the seedlings of Tsoongiodendron odorum after fertilization with N24P0K20 were raised by 56.8%,38.7%,107.4% and 108.6% respectively,and those of Erythrophleum fordii were increased by 7.2%,10.3%,12.3% and 12.1% respectively.For conifers,the fertilizer rate of N24P30K0 is the best one.The above ground and under ground biomass of the seedlings of Pinus elliotii were increased by 78.8% and 93.6% mor than those of the check,and for Pinus massoniana increased by 11.5% and 27.7% respectively.
