央视网消息（焦点访谈）："春争日，夏争时"，说的是春季播种需争分夺秒，而夏季田间管理更需精准把握每一刻。夏粮收完紧跟着就是夏种， 也就是播种秋粮。除了南方双季稻7月中旬开始播栽之外，截至目前，全国夏播基本结束。眼下，全国粮食主产区土壤墒情适宜，秋粮作物苗情长 势总体较好。提单产、稳面积是我们当前农业政策的核心目标之一，主攻方向是集成推广良田良种良机良法，实施粮食单产提升工程。记者调查 发现，今年各地都在夏播中为提高单产，因地制宜优化粮食种植结构，为推动稳粮增油做了不少工作。现在，就一起去看看夏播中的新变化。 7月12日清早，湖南常德鼎城区镇德桥镇的一边稻田正在收割早稻，平整土地，另一边稻田插秧机正在移栽晚稻秧苗，机器轰鸣，白鹭盘旋。鼎城 区是全国产粮大县，今年当地计划晚稻种植面积63.1万亩，全区晚稻优质稻品种覆盖率达95%以上。镇德桥镇晚稻栽插后持续高温天气较多，在这 里正推广"桃优香占""玉针香""扬泰优128"等水稻品种。 湖南常德鼎城区镇德桥镇农业综合服务中心技术员周伦文："我们这里移栽晚稻的时候温度较高，选用了比较抗高温的品种，为避开后期出现寒露 风，选用了生育期比较适中的品种，同时根据市场需求，推 ...
