| 摘 要： | 利用油松容器苗,进行了氮、磷、钾配比施肥对苗木生长量、生物量和苗木质量的影响试验研究。结果表明,不同施肥处理对油松容器苗各项生长指标均存在显著性差异：氮、磷、钾平衡施肥能够促进油松容器苗的生长量,通过6个配方的施肥试验,筛选出配方试验2（氮、磷、钾比例为2∶1∶1）和配方试验3（氮、磷、钾比例为2∶1∶2）最佳,其苗木质量指数分别为1.18和1.10。

| Abstract: | The experiments of effects of combined fertilization for nitrogen ,phosphorus and potassium on growth ,bio-mass seedling quality were conducted by using container-seedlings of Pinus tableaformis .Result shows that ：dif-ferent fertilization treatments all have significant differences on growth of container-seedlings of Pinus tableaformis . Balanced fertilization of nitrogen ,phosphorus ,potassium can promote the grow th of container-seedlings of Pinus tab-leaformis .Result shows that ：by fertilization experiments with six formulations ,formula experiment 2 （ratio of ni-trogen ,phosphorus and potassium is 2∶1∶1） and formula experiment 3 （ratio of nitrogen ,phosphorus and potassi-um is 2∶1∶2 ） w ere selected ;their seedling quality index is 1 .18 and 1 .10 ,respectively . |
