| 摘 要： | 为了确保国家粮食安全,粮食总产量需要不断增加,而在增产中玉米的增产潜力最大,且玉米是八五三农场的主要农作物之一,因此,分析了八五三农场玉米生产中存在的问题,主要有：品种选用不当,生育期偏短;品种退化;种植密度偏高;品种过于单一,缺乏高产潜力品种;环保施肥欠缺,底肥中氮肥占比例过高,钾肥用量比例较低,总施肥量略显不足;基本不施农家肥;缺乏田间管理。并对此提出应选择耐密、半耐密高光效及稀植型高产品种;采用适当的种植密度;增施肥料,配方施肥;施用有机肥料促进玉米增产;采用种衣剂拌种等技术防治病虫害,加强田间管理;加强农业科技培训;建立玉米高产高效综合配套栽培技术模式进行推广等解决对策,为玉米增产提供理论指导。 |

| Abstract: | For the sake of ensuring the safe production of grain in the country,it is need to continuously increase the total grain yield.while the yield increasing potentialities of maize is the biggest,and maize is one of the main crops at 853 farm,therefore,the problems existing in the 853farm were analyzed.They were:improper variety selection,short growth period;variety degeneration;higher planting density;lack of high yield potential varieties;lack of environmental protection fertilization,higher proportion of ni... |
