不同耕整地机械对油菜播种机适应性试验

为了提高北京地区油菜播种质量，参照相关标准，开展了驱动耙和灭茬旋耕机2种耕整地方式下的油菜播种机试验。结果表明:与驱动耙对比，灭茬旋耕机的作业质量好，作业效率高，性能较优，但油耗稍大。综合考虑油菜播种机的播种质量发现，驱动耙耕作方式更适合油菜播种机，在播种机设定的作业条件下，驱动耙耕整地后播种机的播种均匀性变异系数比灭茬旋耕机低25.5%，各行播种量一致性变异系数低1.3%，同时用种量高0.45 kg/hm2，作业速度低0.09 hm2/h。 

Adaptability Test of Different Tillage and Soil Preparation Machines to Rape Planter

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.
