- 摘要:
- 以16个油葵新品种为试材，采用随机区组设计，研究了各油葵品种的产量以及农艺性状间的关系。结果表明：CN2007产量最高，达4 954.17 kg/hm2，比CK1增产48.07%，比CK2增产80.70%，与CK1和CK2均存在显著性差异，建议进一步进行生产试验；CN2032次之，产量达4 295.83 kg/hm2，推荐作为搭配品种；经过油葵主要农艺性状的相关分析表明，对油葵产量影响最大的因素是盘径、株高和叶片数，盘粒重、结实率、花盘粒数、百粒重和茎粗对产量也是正向影响；因此，在高产品种的选择上要注意选择产量和盘径、株高、叶片数、盘粒重、结实率都高的品种。
- Abstract:
- Taking 16 oil sunflower new cultivars as experimental materials,using a randomized complete block design,the relationship of yield and agronomic characters of each spring oil sunflower were studied.The results showed that the highest yield was CN2007 with 4 954.17 kg/hm2,compared with the CK1,increased by 48.07%,and higher by 80.70% than that of CK2,it showed a significant correlation with the CK1 and CK2,so it recommended for further production test,followed by CN2032,the yield reached 4 295.83 kg/hm2,recommended as a match varieties;agronomic traits of oil sunflower after correlation analysis showed that the main influence factors of yield was the disk diameter,plant height and leaf number,disc weigh,seed setting rate,the number of disk seed,hundred grain weight and stem diameter on yield was positive effect.Therefore,choosing the high yield varieties should pay attention to select the yield and the disk diameter,plant height,leaf number,disc weigh and seed setting rate were high varieties.
