| Abstract: | The fertilizer effect on a virus-free vegetable potato cultivar,Xuanshu No.3,was studied through "3414" experiment.The results showed that the optimum N,P2O5,and K2O application dose were 200.6,129.3,and 215.3 kg/hm2 respectively in high fertility soils,under this condition,the yield of the potato cultivar could reach 10 777.1 kg/hm2 The optimum application dose of N,P2O5,and K2O in meddle fertility soils were 192.9,183.8,and 83.6 kg/hm2 respectively;and in low fertility soil were 74.1,87.0,and 29.1 kg/hm2 respectively;and the corresponding yields were 13 713.0 kg/hm2 and 9 070.8 kg/hm2 respectively. |
