摘　　要：首次探究不同氮磷钾施肥用量对无患子幼龄林生长的影响,为无患子人工林培育的精准施肥提供科学依据。通过正交试验设计,以氮磷钾的3种水平的不同组合对无患子幼龄林生长影响进行研究。结果表明:施肥能促进无患子幼林的生长,氮肥和磷肥对无患子的苗期生长影响差异显著,氮5 g/株、磷5g/株和钾5g/株这一组合处理的树高、胸径和材积均为最高值。The test of different dosage of NPK in sapling growth of Sapindus mukurossi was studied, which provided the scientific basis of precision fertilizer in plantation cultivation. Through the orthogonal experiment, using different combination of 3 level of NPK to study the growth condition of sapling growth of Sapindus mukurossi. The result showed that applies fertilizer could promote growth of sapling growth of Sapindus mukurossi, there were variations in applying NP fertilizer in sapling growth of Sapindus mukurossi, the height and DBH of combination of N 5 g, P 5g and K 5g were the highest, which provided the scientific basis of rational fertilization in sapling growth of Sapindus mukurossi.
