Ren Tingbo et al (Guizhou Institute of Oil Crop ,Sinan,Guizhou 565109)  
Study results showed:there were very significance different effect of row width,planting density,interact of row and planting density on rape variety--Youyan No.9 yield,there were no significance difference between fertilizations.10.87% of yield was increased in the planting density from 12×10 4 plant/hm 2to 9×10 4?plant/hm 2;5.71%,in width-narrow to equal row.In the planting density of 12×10 4?plant/hm 2 with equal row,the yield increased by 12.30%.High-yielding cultivation measures of Youyan No.9 were:the planting density was 12×10 4plant/hm 2,width-narrow row planting was used, the amount of nitrogen fertilizer was 270?kg/hm 2;P 2O 5,180 kg/hm 2;K 2O,225 kg/hm 2 and B,22.5 kg/hm 2,and the highest yield reaches to 3?738.90 kg/hm 2.
