| Abstract: | To reduce the investment of labor force and increase the efficiency of rapeseed production,a mathematical model about yield and planting factors for Qianyou 22 was constructed.To obtain yield over 180 kg/667m2 in Guiyang at low density,the best planting models of hybrid rapeseed Qianyou 22 were that amount of N was in the range of 18.13~21.66 kg /667m2,suitable sowing time was September 14~September 20,and suitable planting density was 3 453~3 940 plants/667m2. |
