| 摘 要： | 为探讨浅山区甘薯种植农户经常施用的薯类专用肥效果,确定专用肥用量,以西瓜红为材料,研究了大田条件下,肥料配比N：P2O5：K2O为15:10:18的薯类专用肥不同用量(Z0:0,Z1:225,Z2:450,Z3:675kg/hm2)对甘薯产量及土壤养分的影响。结果表明：处理Z2产量最高,为44715kg/ hm2,比Z0增产44.6%。在试验条件下,薯类专用肥的最佳用量为450 kg/hm2。

| Abstract: | In order to investigate the effect of potato specialized fertilizer commonly used by farmers in shallow mountainous areas for sweet potato cultivation, determine the amount of specialized fertilizer, watermelon red was used as a material to study the effects of different amounts of potato specialized fertilizer (Z0:0, Z1:225, Z2:450, Z3:675kg/hm2) with a fertilizer ratio of N: P2O5: K2O of 15:10:18 on sweet potato yield and soil nutrients under field conditions. The results showed that the yield of treatment Z2 was the highest, at 44715kg/hm2, which increased by 44.6% compared to Z0. Under experimental conditions, the optimal dosage of potato specific fertilizer is 450 kg/hm2. |
