Abstract: To compare the effect on potato yield and farming income by different cultivation methods,tests were conducted from Winter 2008 to Spring 2009.At the same time,indices of potato yield were also investigated.The results showed that,as compared to the conventional cultivation,the straw core cultivation method significantly increased the proportion of large tubers,or the yield.By using this method,the production per hm2 increased 15.4%,the output value increased 15.4%,the profit increased 18.0%,and resistance to Late Blight(Phytophthora infestansis)also improved as compared to the control.
