摘　　要：合理密植是提高作物产量的一项有效措施。试验采用裂区试验方法排列,对5个密度下3个油葵杂交种产量及株高、茎粗、盘径、百粒质量、籽仁率进行方差分析。结果表明,品种、密度以及品种和密度二者交互作用对油葵产量、株高、茎粗、盘径、百粒质量、籽仁率6个性状的影响均显著,而品种对产量、株高、百粒质量、籽仁率的影响要大于密度及品种和密度的交互作用;3个油葵杂交种产量、籽仁率随着密度的增加都呈现先增加后降低的趋势,株高随着密度的增加而增加,茎粗、盘径、百粒质量随着密度的增加而降低。临葵4号和S606明显优于BW667,生产中密度应分别选择7.50万、6.75万株/hm2。建议生产中,选择优良品种的同时选择适合的密度,即良种配良法,以达到提高油葵产量和生产效益的目的。Reasonable close planting is an effective measure to increase crop yield.The experiment was arranged by two factor split zone test,the yield,plant height,stem diameter,disc diameter,hundred grain quality and seed kernel rate of three oil sunflower hybrids under five densities were analyzed.The results showed that variety,density and the interaction of variety×density had significant effects on the yield,plant height,stem diameter,disc diameter,hundred grain quality and seed kernel rate of oil sunflower.The effects of variety on yield,plant height,hundred grain quality and seed kernel rate were greater than density and the interaction of variety×density.In the experiment,the yield and seed kernel rate of three oil sunflower hybrids all showed a trend of increasing first and then decreasing with the increase of density,the plant height increased with the increase of density,and the stem diameter,disc diameter and hundred grain quality decreased with the increase of density.Linkui 4 and S606 were obviously better than BW667,and 75000 plants/hm2 and 67500 plants/hm2 should be selected.It is suggested that in the production,it is necessary to select the best varieties first,and meanwhile select the appropriate density,that is,the combination of the best varieties and the best method,which can increase the yield of oil sunflower and improve the production efficiency.
