摘　　要：通过对甘薯品种龙薯35号进行“3414”肥效试验,结果表明施肥可提高龙薯35号的产量。该品种对钾肥需求量较大,其中产量和氮磷钾施肥量之间呈显著回归关系,建议种植该品种施肥量N为84.9 kg/hm^(2),P_(2)O_(5)为61.8 kg/hm^(2),K_(2)O为258 kg/hm^(2),可获得最佳经济产量。"3414"fertilizer efficiency test of sweet potato variety Longshu 35 showed that fertilization could improve the yield.This variety had a large demand for potassium fertilizer,and there was a significant regression relationship between yield and nitrogen,phosphorus and potassium application.It was recommended to apply amount N of 84.9 kg/hm^(2),P_(2)O_(5) of 61.8 kg/hm^(2) and K_(2)O of 258 kg/hm^(2),the best economic yield could be obtained.
