    摘要:

    以具有黏性的沙壤土、草碳和细河沙按照不同比例配比作为栽培基质,采用单因素试验研究华重楼、狭叶重楼和滇重 楼主要生物学性状的表现。 通过 SSR 法方差分析,结果表明:在沙壤土、草碳和河沙比例为 1 ∶0 ∶0,1 ∶1 ∶0,1 ∶1 ∶1和 1 ∶2 ∶1的配 比基质中,配比为 1 ∶1 ∶1的基质最适宜狭叶重楼、华重楼和滇重楼生长,主要生物学性状表现优异,特别是 3 种重楼的地下茎 长、茎粗和单株地下茎质量均最高,3 种重楼在 6 m2 小区的平均产量分别为 13.6,18.8 和 15.6 kg。 狭叶重楼、华重楼和滇重楼 在沙壤土、草碳和河沙配比为 1 ∶1 ∶1与 1 ∶2 ∶1基质中地下茎产量之间差异不显著,但其地下茎产量极显著高于配比为 1 ∶0 ∶0,1 ∶ 1 ∶0的产量,狭叶重楼、华重楼和滇重楼在 1 ∶2 ∶1配比基质中的地下茎产量显著高于配比为 1 ∶0 ∶0的产量。 通过土壤改良,在具 有一定黏性沙壤土中种植重楼具有可行性,且其产量较高,具有较好经济收益。

    Abstract:

    Different proportions of clayed sand soilꎬ grass char and fine river sand are used as base materials for growing Paris polyphylla var. chinensis Franchꎬ Paris polyphylla var. stenophylla Franch and Paris polyphylla var. yunnanensis Franchꎬ and the single-factor test method is adopted to study their respective biological performances. Results from SSR variance analyses show thatꎬ out of the 1 ∶0 ∶0ꎬ 1 ∶1 ∶0ꎬ 1 ∶1 ∶1 and 1 ∶2 ∶1 proportionings of clayed sand soilꎬ grass char and fine river sand base materialsꎬ the proportioning of 1 ∶ 1 ∶ 1 is most suitable for the growth of Paris polyphylla var. chinensis Franchꎬ Paris polyphylla var.stenophylla Franch and Paris polyphylla var. yunnanensis Franchꎬ which perform the best biologicallyꎬ and particularly their subterraneous stem lengthsꎬ stem diameters and single-plant stem weights all reach the largestꎬ and the average yields of the three varieties growing in a plot of 6 m2 reach 13.6ꎬ 18.8 and 15.6 kg re ̄ spectively. The subterraneous stem yields of the three varieties growing in the 1 ∶1 ∶1 and 1 ∶2 ∶1 proportioned base materials show no marked differencesꎬ but are significantly higher than when growing in the 1 ∶0 ∶0 and 1 ∶1 ∶0 proportions. The sub ̄ terraneous stem yields of the three varieties growing in the 1 ∶2 ∶1 proportioned base materials are significantly higher than when growing in the 1 ∶0 ∶0 proportions. Through soil reclamationꎬ it′s feasible to grow Paris polyphylla in clayed sand soilsꎬ with good yields and economic benefits.
