摘 要：[Objectives]To find a sustainable production model for potato at low latitude plateau in winter in Yunnan Province.[Methods]Xuanshu 2 potato variety was tested in prefectures of Yunnan *** covering experiment was conducted in two trials(open field experiment and green house potted experiment).Impacts of three cultivation factors were analyzed:(i)three cultivation models(T1,T2 and T3),(ii)planting density(T1,T2 and T3),(iii)soil covering(T1,T2,T3,T4)on plant growth,and yield production.[Results]The soil moisture content,temperature,roots growth,stems development,leaf area index,and number-weight of tubers per plant and per plot(g)have significantly increased with commercial yield average of 45 t/ha.[Conclusions]The combination of this method with modern agriculture mechanization should be further popularized and applied in large scale planting in regions with climatic conditions similar winter season in Yunnan Province,so as to make contribution to the satisfaction of the world population potato consumption.
