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。
利用油鬆容器苗，進行瞭氮、燐、鉀配比施肥對苗木生長量、生物量和苗木質量的影響試驗研究。結果錶明，不同施肥處理對油鬆容器苗各項生長指標均存在顯著性差異：氮、燐、鉀平衡施肥能夠促進油鬆容器苗的生長量，通過6箇配方的施肥試驗，篩選齣配方試驗2（氮、燐、鉀比例為2∶1∶1）和配方試驗3（氮、燐、鉀比例為2∶1∶2）最佳，其苗木質量指數分彆為1．18和1．10。

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 .
