晚播小麦遇寒潮，德州种粮大户和农技人员出招应对 麦田盖上"保温被" 今年德州冬小麦普遍播期晚、出苗晚，田间管理尤为关键。几天前的一场寒潮与降雪，给小麦的保 温保墒、促弱转壮带来了一些新问题，德州种粮大户和农技人员及时出招应对。 日前，在武城县武城镇南北官庄村种粮大户刘凯的麦地里，工人分工协作，正有条不紊地为小麦幼 苗铺设地膜，一派繁忙的冬管景象。"铺地膜的作用首先是保墒，能锁住田间水分，能提高地温，地温 能提高到1～3℃。"刘凯介绍。 在这个老把式看来，提高地温促使小麦春节前有效分蘖很重要。对于晚播小麦来说，这个时候的寒 潮不利于麦苗生长。刘凯说，现在麦苗虽然出了，但还是"一根针"的状态。要想来年产量有保障，春节 前分蘖，提高亩穗数很关键。"而相比来年春天分蘖，春节前分蘖更能长出有效蘖。" 刘凯从自己种的100亩小麦中，选出苗情较弱的23亩，组织人工全部铺上了地膜。"总成本大约在 100元/亩。地膜加人工，每亩80元左右；明年3月份'练苗'时还需要一次打孔放风，每亩要20元左 右。"刘凯说。 这是刘凯第一次尝试小麦地膜覆盖栽培技术，他坦言："为麦田盖层'保温被'，也是抱着试验的心 态。"他有自己的考量：自己种 ...
