Along with the dwarfing of the newly bred cultivars and innovation of the farming system, the planting density of the multiple cropping oil sunflower has been on a trend of increase in the production. The results of the study of the dense planting cultivation showed that the proper dense planting could increase the values of the related groups' physiological parameters closely related to the yield, was conducive to the synthesis and accumulation of the photosynthetic products and was good for the increase of production. The production investigation and cultivation practices shows that the dense planting cultivation of the multiple cropping sunflower is feasible, and the key points of the dense planting cultivation technology has formed.
