The invention provides a two-stage cultivation method for Paris polyphylla var. yunnanensis(Franch.)hand.-mazz.. The method comprises three parts, i.e. high-quality seedling raising, commercial Paris polyphylla var. yunnanensis(Franch.)hand.-mazz. cultivation and field management, wherein the high-quality seedling raising step comprises seed germination and seed seedling raising, seeds are timely applied with a leaf fertilizer and topdressed with farm manure after germinating, water management is reinforced, and seedlings are transplanted after being cultivated for 3 to 4 years; the commercial Paris polyphylla var. yunnanensis(Franch.)hand.-mazz. cultivation step comprises land selection and preparation, the three to four-year-old seed seedlings are transplanted according to seedling size grades after being tumbled in November to December, the number of large seedlings (equal to or heavier than 10 grams) is 20,000 to 250,000, and the number of small seedlings (5 to 10 grams) is 250,000 to 30,000; after the transplanted seedlings survive, the leaf fertilizer is topdressed in a vigorous growth period, farm manure is timely topdressed after sprout tumble in winter, and a Paris polyphylla var. yunnanensis(Franch.)hand.-mazz. medicinal material can be harvested after 4 to 5 years. According to the method, the investment cost is effectively shared, the investment cycle is reasonably divided, Paris polyphylla var. yunnanensis(Franch.)hand.-mazz. seedling propagation and commercial medicinal material cultivation are normalized and specialized, and the healthy and rapid development of the industry is promoted.
