摘　　要：对玉米(Zea mays L.)新品种华玉11、郧单20采用集成高产栽培技术,宽行距90 cm,以利于快速通风散湿;幼苗定向移栽,通过提高群体植株叶片光照总面积有效提高光合效率;采用单穴双株栽植方式,有效提高种植密度;在植株7~9叶期化调矮化处理,有效促植株健壮生长而防倒伏、倒折发生。结果表明,科学采用育苗定向移栽、宽行增光透风、单穴双株增密、化调矮化防倒等栽培技术集成模式,能有效提高玉米单产水平。The high yield cultivation techniques in the new corn(Zea mays L.) varieties Huayu 11 and Yundan 20 were applied. The wide row spacing was 90 cm, which was adopted to facilitated rapid ventilation and moisture distribution. Directional transplanting of seedlings can effectively improve the photosynthetic efficiency by increasing the total light area of the leaves of group plants.The single-point double-plant planting mode is adopted, and the planting density is effectively improved. In the 7~9 leaf period, the plant can be effectively promoted to grow robustly and prevent falling down. The results shows that, the integrated mode of cultivation techniques can effectively improve the yield of maize per unit area, such as directional transplanting, increasing light and air permeability by wide row, dobule plants in one point to increase planting density, chemical-regulated-dwarfing technology to prevent falling down and so on.
