- 摘要:
- 通过不同食用向日葵品种、不同密度的试验，探索同一品种的产量、经济性状、籽粒性状在不同密度条件下的变化趋势。结果表明：密度在28 500~49 500株·hm-2，随着密度的增加产量呈递增趋势；籽粒的长、宽、百粒重随密度的增大呈递减趋势；品种和密度互作间差异显著。SH909和巴葵138品种均在密度为49 500株·hm-2时产量、结实率表现最高，密度在28 500株·hm-2籽粒性状表现最好。
- Abstract:
- Different confectionery sunflower varieties and different density test were conducted to explore the output of the same species，economic traits，seed traits under different density trend．The results showed that when the density between 28 500 and 49 500 plant··hm-2，and the yield increased with the density increasing；the length and wide of grain and 100-seed weight were decreased with the density increasing；there was significant difference in interaction of variety and density.the yield and the performance of SH909 and Pakistan Kwai 138 were all the highest at 49 500 plant· hm-2，when the density at 28 500 plant ·hm-2，seed traits were the best.
