摘要
在甘薯主产区的灰赤沙土、灰黄泥沙土、赤沙土3个土壤类型设置5个点进行"3414"试验,结果表明:对甘薯产量影响为氮﹥钾﹥磷;每667 m2施N 13.26 kg、P2O54.28 kg、K2O17.39 kg时甘薯产量最高,为1 859.38 kg;每667 m2施N 12.80 kg、P2O54.11 kg、K2O 16.71 kg时经济效益最佳,产量为1858.04 kg。
A ＂3414＂ design trial was conducted at five spots of three soil types i.e. grey-red sand soil, grey - yellow sand field and red sand soil in main producing area of sweet potato. The results showed that effects of N, P and K on yield of sweet potato were N 〉 K 〉 P. When fertilizing N 13.26 kg, P/O5 4.28 kg, and KzO 17.39 kg per 667 m：, the yield of sweet potato got the maximum of 1859.38 kg. And the best economic yield of 1858.04 kg was realized with fertilizer-applying rates N 12.80 kg, P205 4.11 kg, and K20 16.71 kg per 667 mz.
