玉米是喜温喜光作物，增加光照可以提高产量。目前高产地块种植密度增加，结果叶片相互交错、重叠，不利于光合作用。如果定向栽培，使互生的叶片一头朝东，一头朝西，从日出到日落充分接受光照，充分进行光合作用。我们可在幼苗期用自制的转向器将南北向的苗子搬成东西向，即 Corn is a hi-temperature light crop, increasing light can increase production. At present, the planting density of high-yield plots increases, resulting in staggered and overlapping leaves, which is not conducive to photosynthesis. If directed cultivation, so that the leaves of each other toward the east east, west, from sunrise to sunset full illumination, full photosynthesis. We can use the home-made steering gear in the seedling stage to move the north-south seedlings east-west
