摘　　要：为改善甘薯品质、提高产量和增加无公害甘薯的上市率,通过肥料的"3414"田间肥效试验来确定鲜食甘薯的最佳施肥量和配比。试验结果:中产地667 m2N、P2O5、K2O最佳施肥量分别为10、7、13.5 kg,低产地为6.5、13.62、12.62 kg。The optimum fertilization amount and the formula are confirmed by ＂3414＂ field trail for improving sweet potato quality, increasing the yield and the listed rate of non-pollution sweet potato. The results show that： the optimum fertilization amounts of N, P205, K20 per 667 m2 are 10, 7, 13.5 kg in mid-yield fields, 6.5, 13.62, 12.62 kg in low-yield fields.
