| 摘 要： | 为了探索辽宁地区的栽培管理技术，本试验以‘辽芝7 号’为试材，采用随机区组设计，设4 个播期和6 个种植密度处理，调查生育期、产量构成因子及产量。结果表明：不同播期对芝麻的生育进程和生育期均有影响，随着播期的延迟，缩短了从出苗到现蕾的营养生长时间和开花期，生育期相应缩短。不同播期、不同种植密度对产量影响均达到极显著水平，对产量构成因子中的单株蒴果数影响显著，对蒴粒数和千粒重影响不显著，但随着播期延迟和种植密度增加，蒴粒数和千粒重均呈下降趋势。综上，在北方一年一熟制春播区的辽宁芝麻种植区适宜5月10—20日播种，种植密度为15万~22.5万株/hm2。

Effect of Sowing Date and Planting Density on Characters and Yield of Sesame |
| |
| Abstract: | To explore the cultivation technology of sesame in Liaoning,‘Liaozhi 7’was used as the material, and a random block experiment was conducted with 4 sowing dates and 6 planting densities. The growth period, yield composition factor and yield were investigated. The results showed that different sowing dates affected the growth process and growth period of sesame. The vegetative growth time from seedling to squaring stage and the flowering period were shortened along with the delaying of the sowing date, and the growth period was also shortened. Different sowing dates and planting densities affected yield significantly, for the yield factors, the effect on the number of capsule per plant was significant, while that on capsule number and 1000- grain weight was not significant. With the delaying of sowing date and the increase of density, the number of capsule grains and the weight of 1000 grains decreased. All together, in spring sowing areas of Liaoning, the suitable sowing date is May 10 to 20, and the optimum density is 15.0×104-22.5×104 seedlings/hm2. |
