Abstract: An experiment was made to optimize cultivation of the rape Hanyou 9（ Brassica napus）,and a quadratic orthogonal rotation combination design with 5 factors including sowing date,density,supplement of nitrogen,supplement of phosphorus,supplement of potash was arranged to observe the effect of the factors on the yield of Hanyou 9. The results showed that the 5 factors gave different effect on the yield of Hanyou 9 in the order of supplement of nitrogen ＞ potash ＞ sowing date ＞ phosphorus ＞ density. Analysis of the relationship between the factors and yield showed that the rape yielded the highest when treated with nitrogen fertilizer at a rate of 167. 85 kg·hm^-2,with phosphorus fertilizer at a rate of 96. 6 kg·hm^-2,or with potash fertilizer at a rate of 75. 6 kg·hm^-2,or in the sowing date of September 11,or with the density of 12. 30 ten thousand plants·hm^-2. Computer simulation revealed that 93 optimal sets of cultural patterns gave rapeseed yield ≥3 150 kg·hm^-2,with their cultural measures being that the rape is planted at the density of 11. 70-12. 30 ten thousand plants·hm^-2,and applied with fertilizer of nitrogen at a rate of 174-186 kg·hm^-2,phosphorus at 85. 95-94. 05 kg·hm^-2,and potash at 84. 90-95. 10 kg·hm^-2.
