播种期和种植密度对夏芝麻产量的影响

Effect of Sowing Period and Planting Density on Yield of Sesame

以豫芝10号芝麻品种为试验材料,探索了不同播种期和种植密度对夏芝麻产量的影响。结果表明,播种期和种植密度对籽粒产量有较大影响。适宜的播种期为5月下旬至6月上旬;在砂姜黑土中等肥力下,适宜种植密度为15.0万～16.5万株/hm^2,可获得籽粒单产1350～1500 kg/hm^2。

Sesame variety of Yu Zhi No.10 was adopted to study the effect of different sowing period and planting density on sesame yield.The results showed that there was a remarkable yield response of sesame to sowing stage and planting density.The suitable sowing period was in the end of May to the first ten day of June.And the proper planting density was from 150000 to 165 000 per hectare,achieving the higher yield of 1350 to 1500 kg/hm^2.
