玉米增产作为缓解粮食危机的重要因素，已经越来越受到社会的关注。为此，以北方干旱地区玉米覆膜密植的增产新农艺要求为设计条件，针对现有机具在种植过程中存在成本过高、操作复杂甚至漏播重播等问题，利用PRO/E进行建模设计并进行试验。结果表明：本机器结构紧凑，成本低廉，操作简单，各项性能指标符合农艺的覆膜密植要求。

he increase production of corn is paid more attention now because it is important to relieve the food crisis .The research is based on agricultural requirements which corns are planted with film mulching and closely in the northern arid region , because there are many drawbacks which are expensive and complex on the machines which we have now .Some machines even have the drawbacks that missing seed and multi-seed in the seeding process .The machine was designed by PRO/E and then it was experimented in the field .Experiments show that: the design of covering film planting ma-chine is cheap and it is easy to manipulate .According to the result which was measured , the machine is met the agricul-tural requirements which corns are planted with film mulching and closely .
