摘　　要：玉米是我国的重要粮食作物,提高玉米单产对保证粮食安全具有重要的现实意义。定向播种是指种子在播种的过程中,在一定外力的作用下干预种子方向的一种播种方式。它通过合理排列作物叶片,改善作物田间的光照和通风情况,更好地利用光能,并可以增加种植密度,达到提高单产的目的。在分析我国作物定向播种的历史、现状及机械化定向作业发展的前提下,分析了玉米机械化定向播种的技术难点和解决对策,为实现玉米机械化定向播种技术提供了依据,对促进玉米的高产和稳产具有重要的意义。Corn is one of the most important food crops.It is of great realistic significance to ensure the food security by increasing the output of each stalk.Oriented seeding is a seeding method that the direction of the seeds is interposed by external force during seeding.In this manner,the plant leaves are arrayed reasonably;the illumination of plants is improved as well as the farm is well-ventilated;the luminous energy is used fully and planting density is raised.For these reasons,the yield is increased.In this paper the history and current situation of oriented seeding and direction mechanization in our country are analyzed.In this precondition,the technique difficulty and solutions are discussed.The basis of corn mechanization oriented seeding technology is provided in this paper and it is important to promote high yield and dependable crop of corn.
