摘  要：
在江西红壤旱地研究了播期和密度对秋芝麻农艺性状、经济性状、产量及品质的影响。结果表明:播期对芝麻株高、主茎果轴长和单株干物质重有显著的影响,其中7月1日播种的株高最高,单株干物质重最重;种植密度对始蒴部位和主茎果轴长有显著的影响,随着密度的增加,始蒴部位有升高的趋势,而主茎果轴长有缩短的趋势;播期对芝麻单株蒴果数和产量均有显著的影响,提早播种有利于单株蒴果数和产量的提高;密度和播期对芝麻含油量的影响不显著;最适宜的播期和密度组合为7月10日播种、种植密度45.0万株/hm2,在此条件下,芝麻产量最高,达1147.5kg/hm2。

摘  要：
The effects of different sowing dates and planting densities on the agronomic traits,economic characters,yield and quality of autumn sesame in the red-soil dryland of Jiangxi province were studied.The results indicated that sowing date had significant effects on the plant height,fruit-axis length on main stem,and single-plant dry matter weight of sesame; sesame had the highest plant height and the biggest single-plant dry matter weight when it was sown on July 1st.Planting density had significant effects on the position of initial capsule,and fruit-axis length on main stem of sesame; when planting density increased,the position of initial capsule revealed a rising trend,and the fruit-axis length on main stem showed a shortening tendency.Sowing date had significant effects on both the number of capsules per plant and the yield of sesame,and earlier sowing date was beneficial to the increase in the number of capsules per plant and the yield.Both planting density and sowing date had no significant influence on the oil content in sesame.The optimum sowing date and planting density were July 10 th and 450000 plant/hm2,respectively; under this combined condition,the yield of sesame was the highest,being 1147.5kg /hm2.
