Abstract: Pinus kesiya var .langbianensis is a native tree species in Simao City , with fast-growing , barren-landtolerating and excellent timber .By adopting stepwise clustering analysis , the classification of 100-day container seedlings was studied .Three classes , i .e .Ⅰ , Ⅱ and Ⅲ , were preliminarily categorized , among which seedlings with height 18.5 cm and base diameter 0.29 cm were clustered in the Class Ⅰ , seedlings with 15.5 cm height 18.5 cm and 0.24 cm base diameter 0.29 cm were in Class Ⅱ , and seedlings with height 15.5 cm and base diameter 0.24 cm were in Class Ⅲ .The results of variance analysis and plantation experiments showed that the seedling classification was practical and could guide the seedling production and cultivation .And furthermore , fertilization experiments indicated that 100 g nitrogen , 50 g phosphorus and 50 g potassium fertilizer could meet growth requirements of young stands .[ Ch , 3 tab .11 ref .]
