摘要：

通过田间试验研究了氮肥、氮磷肥配施以及缓/控释肥料对国芝二号和郑芝95-8产量、干物质积累和叶绿素含量的影响，试验结果表明：施肥能显著提高芝麻产量，使国芝二号增产9.90%~41.97%，郑芝98-3增产16.00%~42.03%；施用缓/控释肥料处理产量均最高，分别为1695.20kg/hm2和1394.40kg/hm2。施肥使芝麻的千粒重增率分别为13.10%~31.80%和25.47%~29.59%。施用氮肥平均增产12.95%，磷肥平均增产5.86%，缓/控释肥料与等养分量的常规化肥相比平均增产18.90%。施肥能使芝麻株高、叶片数、叶绿素含量、株蒴数、蒴粒数和干物质积累增加，促进了芝麻的生长发育。

Abstract:

In this paper, field experiment was conducted to study the effects of nitrogen fertilizer, nitrogen and phosphorus fertilizer, and slow/controlled release fertilizers on the yield, dry matter accumulation and chlorophyll content of Guozhi2 and Zhengzhi95-8, the results showed that fertilization can significantly increase the yield of sesame, the increase rate is 9.90~41.97% with Guozhi2 and Zhengzhi95-8 is 16.00%~42.03%. The yield of CRF is the highest, and there are 1695.20kg/hm2 and 1394.40 kg/hm2 respectively. Fertilization increased 1000-grains weight of sesame, the increase rate were 13.10%~31.80% and 25.47%~29.59%. Nitrogen fertilizer increased yield by 12.95% averagely, phosphorus fertilizer is 5.86%, and slow/controlled release fertilizers is 18.90%, compared to conventional chemical fertilizer with equivalence nutrient content. Fertilization could also improve sesame plant height, leaf number, chlorophyll content, capsules per plant, seeds per capsules and dry matter accumulation, and promoted the growth and development of sesame.
