| 摘 要： | 研究了不同种植密度条件下黑芝麻干物质积累与产量间的关系,结果表明:在南昌地区中等肥力水平和秋种条件下,随着种植密度的增加,黑芝麻赣芝9号的株高增加,最低结蒴部位升高,茎粗缩小,单株蒴果数减少。单位面积干物质积累量与产量间呈正相关关系。最佳种植密度为22.5万株/hm2。

| Abstract: | The relationship between the dry matter accumulation and yield of black sesame Ganzhi No.9 under different planting densities was studied.The results showed that： under the conditions of medium fertility level and autumn planting in Nanchang area,when the planting density of black sesame increased,the plant height and the lowest capsule part were enhanced,and the stem diameter and the number of capsules per plant were reduced.There was positive correlation between dry matter accumulation per unit area and yield.The best planting density was 225 thousand plants per hectare. |
