The rapeseed, as the second oilseed crop in China, is an important source of edible oil. Reasonable planting density can improve rapeseed production efficiency, and indirectly increase farmers’ the production enthusiasm of planting rapeseed. To gain a more comprehensive understanding of the study on effect of rapeseed yield to planting density, this article reviews the effect on planting density to yield in rapeseed, including the influences of the interaction between cultivation factors (variety, sowing period, and fertilization), the impact of plant density to lodging resistance and growth and development (biological characteristics, agronomic characteristics, yield traits, and quality tracts), and planting density and the relationship between light and planting density, are reviewed. The lodging resistance of oilseed rape and population yield of different rape varieties can be improved by choosing the appropriate sowing date and fertilizer application, and give full play to the rational utilization of resources and the maximization of benefits. The oilseed rape can make rational use of light and nutrients, which is conducive to dry matter accumulation and yield improvement, with proper planting density. This review will provide a theoretical basis and practical support for rapeseed planting, management, and mechanized production. |
