摘要
林下种植黄连(Coptis chinensis Franch.)与搭棚栽连相比,林下栽连的人工投入和材料更少。对不同的林下种植黄连后土壤养分进行调查,通过主要成分分析及聚类分析验证,科学反映了各林下黄连地的土壤肥力水平,为科学施肥提供了理论依据。
In comparison with planting Coptis chinensis Franch. under artificial shelter, planting it under forest, needs less labor and material inputs. In this paper, through principal component analyses and cluster analysis, various soil nutrients af- ter planting Coptis chinensis under forest are investigated, which scientifically reflects the levels of soil fertility in these un- derstory areas, and provides theoretical guidance for scientific fertilization.
