Abstract: The aim was to study the cultivation models of winter- planting potato and the potato variety suitability of‘Dianqianyu No.23’in Guizhou. In the experiment,‘Dianqianyu No.23’of Pre-basic seed was used to study the difference in the characteristics and yield of winter- planting potato on the four mulches cultivation models. The results showed that compared with the control, these models with four mulches could make potato emergence earlier 2-15 days and raised soil temperature 0.41-2.35℃of land than others, the growth period shortened by 4-10 days. By surveying seedling rate and seeding stage, the tillage of the arched shed was the best. By surveying yield, character and the commercial potato rate, the tillage with straw covering was the best in all treatments. The yield of the tillage with straw covering has increased by 20.3%. The potato variety‘Dianqianyu No.23’and the tillage with straw covering should be widespread applied in Libo County.
