中新社辽宁彰武11月4日电 题：辽宁彰武"麦豆轮作"：麦浪固沙 豆香富农 作者 王涵 禹瑞斋 深秋时节，辽宁省阜新市彰武县的田间恢复了平静。收割后的作物根茬整齐地伫立在褐色土壤之上，与 远处泛着白光的沙地形成强烈反差，这是当地持续推进沙化耕地治理的生动写照。 彰武县地处科尔沁沙地南缘，历史上是辽宁沙化最严重的区域之一。每年春秋两季，大风如期而至，全 县96.07万亩沙化耕地曾是主要风沙源。作为新中国治沙的起点，彰武县与风沙的博弈从未停止。 自2023年起，彰武县开始探索在沙化耕地上进行"麦豆两茬"的轮种模式，即在同一年内，先后在同一片 土地上播种麦子和大豆。这一尝试既有效遏制了风沙侵蚀，又实现了土地"一年两收"，让农民收入实实 在在得到提升。 这一轮种模式的成功离不开精准的时序安排。通过液体地膜等技术，当地将春小麦的播种提前至3月 初，这使得麦苗在4月风沙最猛烈时已能守护地表，待7月收获后立即播种大豆，其根瘤菌的固氮作用和 根茬又为秋冬表土提供了坚实屏障，形成"春护土、秋固沙"的生态防护网。 "经过多年推行麦豆轮作、有机肥还田等措施，土色从黄白转为浅褐，这个变化来之不易。"彰武县农业 发展服务中心技术部副部长 ...
