| 中文摘要: |
| 研究以杂交油菜新品种润普丰为试验材料，以沣油737为对照，设置7个密度梯度，从农艺性状、产量及品质三个性状来探索品种的适宜种植密度。结果表明，密度对这三个性状均有不同程度的影响，其中对产量影响最大，在31.5万株/hm2密度处理下产量最高，达3 619.35 kg/hm2，较同密度下对照品种增产8.31%。综合三个性状分析，在27~36万株/hm2密度处理下能够获得农艺性状结构合理，产量较高，菜籽品质较好的植株。因此,陕西汉中地区润普丰的直播适宜密度应该在27~36万株/hm2之间。 |
| 英文摘要: |
| This study used the new hybrid rapeseed variety ‘Runpufeng’ as the test variety, with ‘Fengyou 737’ as the control variety, and established seven planting density gradients to determine the optimal density by evaluating agronomic traits, yield, and seed quality. The results showed that planting density affected all three traits to varying degrees, with the greatest impact on yield. The highest yield was obtained at 315,000 plants/hm2, reaching 3,619.35 kg/hm2, which was 8.31% higher than that of the control variety at the same density. A comprehensive assessment of the three traits indicated that a density range of 270,000–360,000 plants/hm2 produced plants with a reasonable agronomic structure, relatively high yield, and good seed quality. Therefore, for direct seeding in the Hanzhong region of Shaanxi Province, the suitable planting density for ‘Runpufeng’ is 270,000–360,000 plants/hm2. |
