[目的]在高密度栽培条件下，研究向日葵二比空栽培模式不同种植密度之间产量的差异。[方法]该研究以常规单垄单作栽培模式为对照，比较二比空栽培模式的不同种植密度对向日葵植株性状、产量构成因素及产量的影响。[结果]试验结果表明，在相同密度条件下，二比空栽培模式产量高于常规栽培模式，且适度降低种植密度可进一步提高向日葵产量。种植行株距为60 cm×52 cm 时，二比空栽培模式较常规栽培模式增产6%左右，植株性状、产量构成因素均优于常规栽培模式，是最适宜的栽培密度。[结论]该研究揭示了向日葵二比空栽培模式增产增效的理论依据，为建立向日葵高产栽培技术体系提供技术支持。

Objective]To compare the difference in yield of sunflowers under different planting densities of empty every two rows solid permeation cultivation under the condition of high density cultivation. [Method]Using the conventional single ridge cultivation as a control, to study the effects of various planting densities of empty every two rows solid permeation cultivation on the plant characters, yield and yield components of sunflower. [Result]The yield of empty every two rows solid permeation cultivation was higher than that of the control under the same planting density, and moderate decrease of planting density could further improve the yield of sunflower. When the row and plant space was 60 and 52 cm, the cultivation pattern of empty every two rows improved the sunflower yield by 6%, and the plant characters and yield components were much better compared with those of the normal cultivation pattern. So it was the most appropriate cultivation density. [Conclusion]The study reveals the theoretical basis of the yield and efficiency increasing of the empty every two rows solid permeation culti-vation model, it provides a technological support for research of sunflower's high-yielding cultivation technology.
