摘　　要：采用一年生厚果鸡血藤容器苗为试验材料,进行氮磷钾配比施肥试验,研究氮磷钾不同配比施肥对厚果鸡血藤容器苗生长量、叶绿素含量、生物量的影响。结果表明:厚果鸡血藤容器苗生长量、叶绿素含量、生物量在不同氮磷钾配比处理之间存在显著差异;每株施用施肥含量为氮4 g、磷4 g、钾0.5 g的氮磷钾配比肥,厚果鸡血藤一年生容器苗生长量、叶片叶绿素含量及生物量均为最大,该氮磷钾配比为最优施肥配比。In this paper,container seedlings of 1-year-old Millettia pachycarpa were used as the experimental material in NPK proportional fertilization trial to research the effects of different proportional fertilizations on the growth,chlorophyll content and biomass of container seedlings of Millettia pachycarpa.The results showed that there were significant differences in the growth,chlorophyll content and biomass of the container seedlings of Millettia pachycarpa between different NPK proportional fertilizations.The NPK proportional fertilization(4 g N+4 g P+0.5 g K)could promote the growth,chlorophyll content and biomass greatly,which was selected as the optimal proportion.
