[Objective]To provide theoretical basis for cultivation techniques of winter potato, the effects of different cultivation models and sowing depth on soil water, temperature and yield were studied. [Method] Favorita and Lishu No. 6 were taken as material. Three treatments of no-covering, rice straw and black film mulching as well as four sowing depths of 5 cm, 10 cm, 15 cm and 20 cm were set. The soil water, temperature, phenological periods, yield and other agronomic traits were measured. [Result] The soil temperatures of rice straw and black film mulching were 1.9 higher than no-covering method, the highest of soil water content were at 5 - 10 cm soil layers of black film mulching in seeding time, plant growth time and tuber enlargement time. The growth period of two varieties were the shortest under no-covering and lice straw treatments. The agronomic traits, yield (57.2, 36.3 t/hm2) and economic benefits of Lishu No. 6 and Favorita were showed surpassingly by sowing depth of 10 cm and 15 cm under black film mulching. [Conclusion]The optimum sowing depth of two varieties were 10 cm and 15 cm under black film mulching treatments. The results could provide scientific reference for the reasonable selection and application of cultivation methods on winter potato production in Guangxi. [ABSTRACT FROM AUTHOR]
