Abstract: In order to improve quality of rape seed sowing in Beijing area，experiment of rape seed sowing machine under two kinds of tillage and land-leveling methods of driving rake and stubble rotary cultivator was carried out.Results showed that，compared with driving rake，stubble rotary cultivator had better operation quality，with high operation efficiency and good performance，but a little more fuel consumption.Considering seed quality of rape planter，driving rake tillage was more suitable for rape planter，under set operation conditions of planter，seed homogeneity variation coefficient of driving rake tillage was 25.5% lower than stubble rotary cultivator，consistency variation coefficient of seed quantity was 1.3% lower，seed quantity was 0.45 kg/hm2 higher，and operating speed was 0.09 hm2/h lower.
