摘要:
为了寻求新葵4号、新葵6号、新葵7号3个品种及其种植适宜密度，在2009年设置了4种密度水平的2因素裂区试验。结果表明：供试各品种所要求的最适密度不同，否则产量和出仁率降低，千粒重变小；油葵是喜光作物，但各品种之间对光能的利用率是不相同的。新葵4号、新葵6号、新葵7号分别以69 450、61 200～72 450和49 500株·hm-2光能利用率最高。
Abstract:
Xinkui No.4，Xinkui No.6，Xinkui No.7 were three main spring sowing oilseed sunflower hybrids which are now grown in large scale in production in Xinjiang region．A two factors split plot experiment was carried out that contained the three varieties and four densities level to study the three hybrids and find the suitable planting density．The results indicated that the three varieties required different optimum density，otherwise the yield and kernel ratio in seed would be lower and 1000-seed weight would be smaller．Although sunflower was a photosensitive crop，there was different utilization of light energy among varieties．The maximum utilization of light energy of Xinkui No.4，Xinkui No.6 and Xinkui No.7 was obtained when the density was 69 450 plant?hm-2，61 200～72 450 plant·hm-2and 49500 plant·hm-2，respectively．
