Abstract: In order to obtain the high-yielding cultivation model of the multi-branched rapeseed（Brassica napus L.） line YF368-2, it was studied that the effect of planting density of the line on yield and number of branches. Within the range of density of 8 820~79 410 plants/hm², the number of primary effective branches decreased successively with the increase of density, while the yield increased first, then decreased, then increased. Results show that in the higher fertility rice stubble field yield can be up to 4 350 kg/hm² that can reach or exceed the traditional high yield cultivation model by means of seedling in late August and early September, spraying 15% paclobutrazol（50 g to water 50 kg） during the four-leaf phase, transplanting in early October and transplanting density with around 48 030 plants/hm² This model is not only high yield but also seed-saving, labor-saving, time-saving and high efficiency etc.
