摘要：

为了给芝麻的生产提供施肥的理论依据，采用“3414”测土配方试验设计，通过不同的NPK配比了解群体的生育变化并进行群体的产量比较，从中筛选出最佳产量和氮磷钾配比，从理论上阐述对芝麻的影响。结果表明，土壤供氮磷钾量分别为N 82.95 kg/hm2、P2O5 30.75 kg/hm2、K2O 69.15 kg/hm2；肥料利用率分别为N 13.46%、P2O5 19.34%、K2O 23.56%。由此得出，氮磷钾配施为N 120 kg/hm2、P2O5 45 kg/hm2和K2O 120 kg/hm2能获得最高的经济产量和效益。

Abstract:

"3414" soil protocol was used in this experiment. Comparing the yield for different sesame population under different ratio of nitrogen, phosphorus, and potassium, and selecting the best ratio for nitrogen, phosphorus, and potassium for the optimal yield, in this way, the theoretical basis of fertilization are offered for the production of sesame in the future. The amount of nitrogen, phosphorus, and potassium from soil were N 82.95 kg/hm2, P2O5 30.75 kg/hm2, and K2O 69.15 kg/hm2. The utilization rate of fertilizer were N 13.46%, P2O5 19.34%, and K2O 23.56%; Sesame were at the maximum economic yield and efficiency when fertilizer N was 120 kg/hm2, P2O5 was 45 kg/hm2 and K2O was 120 kg/hm2.
