Ningza No.21, a new hybrid rapeseed cultivar, was used as the test mate-rial in this study. The common planting models in large-scale production （3 trans-planting models and 2 direct-seeding models） were adopted. Based on the high-yield cultivation, the yield and economic benefits of different planting models were investi-gated. ln addition, the labor costs, agricultural production materials costs and agri-cultural machinery costs of different planting model were analyzed to explore the low-costs and high-economic benefits planting model. The results showed the yields of the 5 planting models were al relatively high with average yield of 3 282.30 kg/hm2, ranging from 2 899.50 to 3 642.00 kg/hm2. Although the average yield and output value of transplanting models were higher than that of direct-seedling models by 429.25 kg/hm2 and 2 189.18 yuan/hm2 respectively, the production costs of trans-planting models were higher than that of direct-seedling model by 2 098.81 yuan/hm2 and the economic benefits were basical y equal. Among the costs of rapeseed pro-duction, the labor costs accounted for more than 60%. ln the labor costs, the har-vesting labor costs represented about 50%. Therefore, under current production con-ditions, the direct seeding and mechanized harvesting should be adopted in the rapeseed production to reduce production costs and improve economic benefits.
