为了提高玉米齐苗率，本文采用不同的播种深度和排种节律，对玉米的齐苗率进行了研究，结果表明，不同品种之间齐苗率存在差异，在试验区间范围内，采用6cm 播种深度，排种节律采用211或2111，补偿齐苗率可以达到93%以上，其中先玉335补偿齐苗率可达100%。采用4.5cm 播种深度，排种节律采用211，所有品种的补偿齐苗率均可达90%以上。

In order to improve the seedling emergence rate of maize,the different depth of sowing and seeding rhythm were studied in this paper. The results show that emergence rate differences were obvious among different varieties. In the test range,compensation emergence rate can reach more than 93% in depth of seeding with 6cm,seeding rhythm with 211 or 2111,of which Xianyu 335 compensation emergence rate rises up to 100% . In the depth of seeding with 4. 5cm,seeding rhythm with 211,all varieties of compensation emergence rate can reach 90% .
