可供灾后改种补种的作物种类虽然多，但田间管理的复杂性和难度不容忽视。由于不是在正常季节播 栽，应采取一些超常规技术手段：早种早管，促进作物早生快发；增加作物群体密度，补充个体生长量 不足的缺陷；管理上以促为主，在短期内使作物有较大的生长量。收获后应加强产销对接，减少农民损 失。 （作者为全国农业技术推广服务中心粮食处高级农艺师，本报记者郁静娴采访整理） 一般来说，受淹超过3天，对产量影响较大或绝收地块，要及时进行改种补种，这也是最有效的救灾措 施之一。对因泥沙冲压一时难以恢复的地块，要尽快清除田间垃圾沙石，深翻耕地，因地制宜进行改种 补种，力争做到不空田、不荒田。 改种补种时，要根据当地温光条件来选择作物。以黄淮海地区为例，7月上旬前，通常改种鲜食玉米、 甘薯、糜子、荞麦、绿豆等作物，尽可能选择短生育期、中早熟或极早熟品种；7月中旬前，改种鲜食 玉米需注意足墒播种，改种荞麦要适当加大播种量和播深；7月下旬后，补种露地蔬菜等短生育期作 物，如小白菜、菠菜、香草、苋菜、竹叶菜等，等雨带水播种，确保正常出苗。 7月以来，大范围集中降雨以及台风"桦加沙"等带来强风雨天气，对农业生产影响较大。9月初，财政部 会同农业农 ...
