贡嘎山东南坡重楼的土壤养分及栽培重楼的性状研究

Study on the Character of Soil Nutrients and Cultivation of Paris polyphylla in the Southeast Slope of Gongga Mountain

通过对贡嘎山东南坡重楼资源实地考察,明确了贡嘎山东南坡野生重楼资源的土壤属冲积土壤和森林土壤,土壤中有机质含量和矿质元素丰富,保肥供肥能力强;对多叶重楼、毛重楼、滇重楼、禄劝重楼、花叶重楼、北重楼和卵叶重楼进行栽培,测定其鲜活地下块茎的径粗、径长、产量和新芽数量等指标,结果表明:多叶重楼地下块茎的径粗、产量和新芽数量最高,平均每株的径粗达5.30 cm,单株地下块茎重量达55.83 g,新芽数量达14.53个;栽培重楼时最适宜的重楼品种为多叶重楼,其次是滇重楼和毛重楼。

Through field investigation of the resources of the south slope of Gongga Mountain,it is clear that the soil of the wild Paris polyphylla resources in the southeast slope of Gongga Mountain is alluvial soil and forest soil.The contents of organic matter and mineral elements in soil are rich,and the fertilizer is strong.The Paris polyphylla Sm.var.polyphylla,Paris mairei Leveille,Paris polyphylla var.yunnanensis,Paris luquanensis,Paris marmorata Stearn,Paris polyphylla M.Biab and other varieties were cultivated.And the yield and number of new shoots were measured for the diameter of the fresh underground tubers.It shows that the diameter of the underground tuber of Paris polyphylla Sm.var.polyphylla,was the highest:the average diameter of each plant was 5.30 cm,and the weight of the underground tuber was 55.83 g,and the number of new shoots was 14.53.Therefore,the test tells that it's better to plant Paris polyphylla Sm.var.polyphylla and the second and third choices are Paris polyphylla var.yunnanensis,Paris mairei Leveille respectively.
