摘要 以郑单958和先玉335等耐密植品种在辽宁地区成功推广的典型案例,对辽宁省玉米品种及推广提出了一些看法。认为:随着生产力水平的提高,特别是土壤肥力、田间管理水平和机械化程度的提高,耐密植品种将成为辽宁省玉米生产的发展方向;栽培技术不能与之配套是当前一些优秀品种未能大面积推广的严重障碍;粮食市场的引导和拉动对优质耐密植品种的推广起到了不可忽视的作用;高质量的种子是优良品种大面积推广的有利保障;技术知识的普及、观念的转变和得力的推广措施为这些品种的成功推广创造了有利条件。 According to successful spreading example of density hybrids such as zhengdan 958 and xianyu 335, this paper put forward some views on maize hybrids and spreading of hybrids in Liaoning province. As productivity level rise, especially the improvement of soil fertility,field management and mechanization de- gree, density-planting hybrids would be the main trend of maize production in Liaoning province. The serious problem of some hybrids could not spread widely was that there was no relevant cultivation supporting measures to these hybrids. The stimulate measures of grain market had a great effect on the spreading of high quality and density maize hybrids. It was an effective guarantee for high quality maize hybrids to spread widely. The popular of technology,change of idea,right-hand of spreading measures created favorable conditions for successful spreading of these hybrids.
