摘要： 为探讨黑芝麻新品种‘赣芝8号’在红壤旱地上的合理氮肥用量，笔者研究了6种氮肥用量(0、60、90、120、150、180 kg/hm2 N)下‘赣芝8号’的产量、植株性状、氮肥农学利用率。结果表明，不同施氮量对芝麻产量影响显著。在所有处理中均以N120的产量、单株蒴数、每蒴粒数最高，其产量高达 1172.22 kg/hm2。而N0处理表现最差，其产量仅为672.78 kg/hm2。收获指数与产量的表现不一，与N0相比，N60、N90、N120、N150、N180的收获指数分别增加了15.99%、14.91%、38.82%、25.68%、17.07%，其中以N90处理的收获指数最高。在氮农学效率方面，表现出N120处理较高，为4.16 kg/kg。通过方程拟合发现，‘赣芝8号’获得高产的合理施氮范围在80~120 kg/hm2之间。

Abstract: In order to explore the effects of different N (nitrogen) application amounts on the growth and yield of ‘Ganzhi 8’, a new variety of black sesame, the author researched the yield, plant character and NUE (nitrogen using efficiency) of ‘Ganzhi 8’ under 6 N application amounts (0, 60, 90, 120, 150, 180 kg/hm2 N). The results showed that N application amounts had significant influence on the yield of sesame. In all treatments, N120 had the highest yield, capsule number of single plant and grain number of single capsule, and the yield was 1172.22 kg/hm2. N0 was the worst of all treatments, and the yield was only 672.78 kg/hm2. HI (harvest index) was not consistent with the yield, compared with N0, HI (harvest index) of N60, N90, N120, N150 and N180 were increased by 15.99%, 14.91%, 38.82%, 25.68% and 17.07%, HI of N90 was the highest. Meanwhile, the NUE of N120 was better than that of the others, the NUE of N120 was 4.16 kg/kg. Through equation fitting, the reasonable range of N fertilizer application amount was 80-120 kg/hm2.
