摘要：杉木幼林Ｐ肥效应极显著，每公顷施２５ｋｇＰ２Ｏ５效应最好，树高增２４％，地径增３０％，ＰＫ、ＮＰ和ＮＰＫ效应也显著；湿地松幼林Ｐ肥效应也极显著，ＰＮ、ＰＫ效应更好，每公顷施５０ｋｇＮ、５０ｋｇＰ２Ｏ５树高增７４％，地径增６９％，施５０ｋｇＰ２Ｏ５、５０ｋｇＫ２Ｏ树高增７２％，地径增６５％；尾叶桉幼林·ＮＰＫ效应最显著，ＰＮ、ＰＫ效应也显著，ＮＫ增幅不大，每公顷施１００ｋｇＮ、１００ｋｇＰ２Ｏ５、５０ｋｇＫ２Ｏ，树高增２４５％，地径增２７９％，胸径增１１５６％。造林时应施足ＮＰＫ基肥。
This paper reports the results of a two-year research on growth response tofertilization in young Cunninghamia lanceolata,Pinus elloittii, Eucalyptus urophylla planta-tions. For Chinese fir,the growth response was significant to the application of P,PK,NPand NPK,and the highest growth appeared in the treatment applied with 25 kg /hm2 of P2O5,which resulted in an increase of 24%in height and 30%in basal diameter. The growth re-sponse of slash pine is remarkable to P,PN and PK,The height and basal diameter of slashpine were promoted by 74%and 69%by the application of 50 kg P2O5+50 kg N/hm2,and72%and 65%by the application of 50 kg P2O5+50 kg K2O/hm2.For Eucalyptus urophylla,the growth response was significant to treatments NPK,NP and NK with the highest growthincrement in NPK,height increased by 245%,basal diameter by 279%and DBH by l156%in treament l00 kg N+ 100 kg P2O5+50 kg K2O/hm2.
