不同栽培基质配比对重楼主要生物学性状的影响研究

Study on the Effects of Different Proportioning of Base Materials on the Main Biological Traits of Paris polyphylla

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 m^(2)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。

Different proportions of clayed sand soil,grass char and fine river sand are used as base materials for growing Paris polyphylla var.chinensis Franch,Paris polyphylla var.stenophylla Franch and Paris polyphylla var.yunnanensis Franch,and the single-factor test method is adopted to study their respective biological performances.Results from SSR variance analyses show that,out of the 1∶0∶0,1∶1∶0,1∶1∶1 and 1∶2∶1 proportionings of clayed sand soil,grass char and fine river sand base materials,the proportioning of 1∶1∶1 is most suitable for the growth of Paris polyphylla var.chinensis Franch,Paris polyphylla var.stenophylla Franch and Paris polyphylla var.yunnanensis Franch,which perform the best biologically,and particularly their subterraneous stem lengths,stem diameters and single-plant stem weights all reach the largest,and the average yields of the three varieties growing in a plot of 6 m^(2) reach 13.6,18.8 and 15.6 kg respectively.The subterraneous stem yields of the three varieties growing in the 1∶1∶1 and 1∶2∶1 proportioned base materials show no marked differences,but are significantly higher than when growing in the 1∶0∶0 and 1∶1∶0 proportions.The subterraneous 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 reclamation,it′s feasible to grow Paris polyphylla in clayed sand soils,with good yields and economic benefits.
