【摘要】 为研究不同生境对多花黄精生长的影响，本文以3年生多花黄精为研究对象，开展桂花、黄柏、杉木及油茶林下间作试验，测量多花黄精的主要生长量指标、叶形态指标、叶片SPAD值、生物量指标并进行多重比较和方差分析。结果表明：林下间作多花黄精的生长与叶形态、叶片SPAD值及生物量积累等方面均表现出显著优势。黄柏林下多花黄精的块茎鲜质量、块茎干质量、单株鲜质量、单株干质量及苗高分别为289.43 g、83.28 g、402.09 g、108.37 g及123.00 cm,显著高于其他处理(P<0.05),较非林下处理分别高49.34%、44.38%、54.68%、46.27%及33.22%;油茶林下的多花黄精叶片SPAD值、叶片鲜质量、块茎鲜质量及块茎干质量表现优异，分别为47.12、24.13 g、269.98 g及73.15 g,较非林下处理分别高9.94%、25.94%、39.31%及26.82%;杉木林下的多花黄精叶长、叶宽、叶片厚度、叶片SPAD值及地径分别为19.94 cm、6.14 cm、0.36 mm、53.28及12.03 mm,显著高于其他处理(P<0.05),较非林下处理分别高21.44%、16.51%、38.46%、24.31%及25.05%。桂花林下的多花黄精茎秆干质量(含浆果)、叶片鲜质量分别为18.31 g、24.77 g,均显著高于其他处理(P<0.05),较非林下处理分别高75.38%、29.28%。综上，林下间作是实现多花黄精高效栽培的核心策略。黄柏林是多花黄精块茎高产的最优生境，油茶林下间作为平衡经济效益与生产成本最具有潜力的模式，杉木和桂花林下间作也表现出显著优势。本研究结果为实践“以林育药、以药促林”的可持续发展模式提供了实证支撑。更多还原

【Abstract】 To investigate the effects of different habitat on the growth of Polygonatum cyrtonema, this study used three-year-old P.cyrtonema as the research subject and conducted intercropping experiments under Osmanthus fragrans forest, Phellodendron amurense forest, Cunninghamia lanceolata forest, and Camellia oleifera forest.The study measured the main growth, morphological indicators, leaf SPAD values, and biomass indicators of P.cyrtonema, and performed multiple comparisons and variance analysis on the repeated measurement data. The results showed that intercropping P.cyrtonema under forests exhibited significant advantages in growth, leaf morphology, leaf SPAD value, and biomass accumulation(P<0.05).The fresh weight of rhizomes, dry weight of rhizomes, fresh weight per plant, dry weight per plant, and plant height of P.cyrtonema under P.amurense forest were significantly higher than all other treatments(P<0.05), being 289.43 g, 83.28 g, 402.09 g, 108.37 g, and 123.00 cm, respectively, which were 49.34%, 44.38%, 54.68%, 46.27%, and 33.22% higher than non-forest treatments. The SPAD value, fresh weight of leaves, fresh weight of rhizomes, and dry weight of rhizomes of P.cyrtonema under C.oleifera forest were also excellent, being 47.12, 24.13 g, 269.98 g, and 73.15 g, respectively, which were 9.94%, 25.94%, 39.31%, and 26.82% higher than non-forest treatments. The leaf length, leaf width, leaf thickness, lesf SPAD value, and stem diameter of P.cyrtonema under C.lanceolata forest were significantly higher than those of other treatments(P<0.05),being 19.94 cm, 6.14 cm, 0.36 mm, 53.28,and 12.03 mm, respectively, which were 21.44%, 16.51%, 38.46%, 24.31%, and 25.05% higher than non-forest treatments. The dry weight of stems(including berries) and fresh weight of leaves of P.cyrtonema under O.fragrans forests were significantly higher than all other treatments(P<0.05), being 18.31 g and 24.77 g, respectively, which were 75.38% and 29.28% higher than non-forest treatments. In conclusion, intercropping under forest is a core strategy for achieving efficient cultivation of P.cyrtonema. P.amurense forests is the optimal habitat for high-yield production of P.cyrtonema rhizomes. C.oleifera forest the most promising model for balancing economic benefits and production costs, and intercropping under C.lanceolata forests and O.fragrans forest also shows significant advantages. The results of this study provide empirical support for the practice of the sustainable development model of “Using forests to nourish medicine, using medicine to promote forests”.更多还原
