Abstract: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
