摘　　要：在强酸性土壤上，柚木不能正常生长；用石灰、有机肥和复合肥改良土壤后．树木生长正常，但如不继续追肥．生长将显著下降；7794、8508号种源的柚木在改良后的土壤上生长最好；7794．8508和3054号种源的柚木表现出对酸性土壤有一定的抗性；来自同一种源的个体之间存在着显著的生长差异．Teak grew extremely poor and even went to die on strongly acid soil. After the soil was ameliorated with lime, organic fertilizer and compound fertilizer,the trees growth became normal. However, the growth of the trees decreased significantly without topdressing of the fertilizers. The teak from provenance 7794 and 8508 grew best on the ameliorated soil, and from provenance 7794,8508 and 3054, to some extent, had resistance to acid soil. Signincant difference in growth of individuals from the same provenance existed.
