Abstract: The result showed that app rop riate combined fertilization ofN, P and K nutrition could obviously enhancethe young growth of Taxus chinensis var. m airei, but excessive fertilizerwould restrain the growth, in the case ofmedium or poor soil fertility, lower content of N, P and organic matter. There were significant differences among theeffects of various combined fertilization ofN, P and K on young growth. The sp rout length, collar diameter growth,branch number and drymatter accumulation under fertilization were more than the CK by 33. 14%～80. 77% , 100.00%～ 161. 90% , 11. 81% ～47. 17% and 207. 42% ～325. 05% respectively. Those four characteristics of 7 thp rescrip tion, the best combination among 15 p rescrip tions,were more than that of 12 th p rescrip tion, the worst one,by 47. 63% , 61. 90% , 35. 36% and 117. 63% respectively. P nutrition had the most important effect on T.chinensis var. m airei growth. The effectwas poor to add the amount ofN and Kwhen the soilwas lack of P. The interaction between N and P was significant and the combined fertilization could obviously p romote the growth of T.chinensis var. m a irei.
