中文摘要：探讨不同套种模式对巴戟天生长的影响,并对巴戟天叶片、根部、叶绿素和多糖含量及土壤性质进行研究,筛选适宜的套种模式.结果显示:最有利于巴戟天的生长模式是模式 3＞模式 1＞模式 4＞模式 2.其中,模式 3 即热带雨林新造林环境下巴西参+巴戟天套种更利于巴戟天叶片和根部的生长、叶绿素的合成和多糖的积累.此外,不同套种模式均可提升林下土壤养分含量.其中,模式 3 中土壤铵态氮、速效磷、速效钾含量均最高.

外文摘要：This paper aims to explore the influence of different interplanting patterns on the growth of Morinda officinalis and to screen the suitable interplanting modes based on the studies of leaf,root,chlorophyll,polysac-charide content,and soil properties.The results indicated that the ranking of the most favorable growth modes was:Mode 3>Mode 1>Mode 4>Mode 2.Among them,Mode 3,Brazilian ginseng+M.officinalis in the new forest environment,was more conducive to the growth of leaves and roots,chlorophyll synthesis,and polysac-charide accumulation.At the same time,all the interplanting models increased the soil nutrient contents,among which the soil ammonium nitrogen,available phosphorus,and available potassium in model 3 were the highest.
