１９９１～１９９５年试验结果表明，在江西分宜花岗岩残积物发育的黄红壤上，杉木幼林施Ｎ、Ｐ、Ｋ及配合处理，使树高、胸径、蓄积总生长量指标分别达到５．６７～６．５９ｍ、８．３５～９．２８ｃｍ、６７．９２２～９６．４１７ｍ３／ｈｍ２，较对照增长５．６％～２０．２％、７．４％～１７．５％、２１．６％～５６．２％。在各种施肥处理中，以５０ｋｇ／ｈｍ２Ｐ２Ｏ５的效果最佳，其连年生长量效应显著持续到第５年；将同等剂量的Ｎ分两次各半施用，其连年生长效应在第５年时才有显著表现；Ｋ的连年生长效应仅表现在低剂量分两次隔年施用上；试验未看出Ｎ、Ｐ、Ｋ各种配合的交互效应
The results from 1991 to 1995 showed that N, P and K of young Chinese fir plantations on the yellow-red soil with granite remnant of Jiangxi Fenyi, so that the tree height, DBH and accumulated total growth index reached 5.67 ~ 6.59m, 8.35 ~ 9.28cm, 67.922 ~ 96.417m3 / hm2, which increased 5.6% ~ 20.2%, 7.4% ~ 17.5% and 21.6% 56.2%. In all fertilization treatments, the effect of 50kg / hm2P2O5 was the best, and the annual growth effect significantly lasted for 5 years. When the same dose of N was applied twice and half halves, its annual growth effect was only in the 5th year There is a significant performance; K annual growth effect only showed low dose divided into two separate applications; test did not see N, P, K interaction with the interaction effect
