【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。更多还原

【Abstract】 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,polysaccharide 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 polysaccharide 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.更多还原
