A new hybrid rape variety Yiyou 21 with high-quality,low erucic and low glucosimolate was used as experimental material. Through sowing period(X1),planting density(X2) and nitrogen rate(X3),two orthogonal design experiment was carried out. Under the transplanting mode,the factors had significant influences on the yield of Yiyou 21,and the order was nitrogen rate sowing period planting density,indicating that in the actual production of Yiyou 21,we should control nitrogen rate and sowing period. The interaction effect between sowing period and planting density was the highest and reached a significant level. Under the condition of sufficient water and fertilizer,the highest yield of Yiyou 21 was found in late-sowing and high-density,early-sowing and low-density can also get high yield,but the lowest yield was found in late-sowing and low-density. Under certain cultivation management measures,the best sowing period,planting density and nitrogen rate for the yield of Yiyou 21 more than 2 860 kg/hm2 were as follows :September 25 th ~29 th,92 839-104 399 plants/hm2 and 215.8-242.8 kg/hm2.
