近日，在甘肃省定西市安定区鲁家沟镇的凤城湖养殖基地，6万只人工养殖的中华绒螯蟹蟹黄正肥，收 获时节随之而至。 作为当地特色养殖项目，鲁家沟镇依托"引洮工程"水资源和冷凉气候条件，采用优质蟹苗繁育，以大 豆、玉米等天然饲料进行科学饲养，养殖的大闸蟹达到高品质标准。 在特色养殖业助力乡村振兴的同时，定西市同步推进生态建设，绘就绿色发展新图景。 初冬时节，当地抢抓秋冬季苗木扎根的黄金窗口期，动员干部群众、志愿者及林草专业团队进行植树造 林活动。 自2021年定西市开展大规模国土绿化行动，即"绿满陇中"行动实施以来，当地以黄河流域生态保护和高 质量发展为核心，统筹推进"三北"工程、水土流失综合治理等重点项目，坚持"适地适树"原则，优选侧 柏、油松等耐旱固碳树种，构建多层次生态防护体系。 近年来，湖南省常德市鼎城区因地制宜，大力推广秸秆还田、离田收储模式，探索农业废弃物资源化利 用新路径。当地种粮大户李建红承包了200亩水稻，今年，他在自家的旋耕机后面加装了埋茬设备，直 接将秸秆粉碎还田。 综合新华社记者报道 湖南省双峰县杏子铺镇双源村到江口村的溪口路提质升级后，成为带动乡村产业发展，带火乡村旅游的 致富路、产业路。 ...

笔者日前在工作中发现一个奇怪的问题：一边是大量秸秆堆放在田埂、水渠边，另一边，生物质电厂却 面临"吃不饱"的问题，难以获得稳定的原料供应，这背后的原因何在？ 素有"中国小麦第一县"之称的河南省滑县，每年秸秆产量稳定在200万吨以上。每年"三夏""秋收"时 节，各级政府部门都将秸秆禁烧作为重中之重的工作来抓，实行网格化管理，不间断巡查值守。 其实，解铃还须系铃人，真正要把好事做好，还须共同整合资源。对生物质能源企业来说，必须把收储 问题解决好，拉长秸秆收储运的链条，生产之前多调研，和农民多沟通，看农民欢迎哪种收储方式，然 后从自身做起，多为农民着想。 当然，秸秆由于自身的物理特性，密度小、体积大、分布松散，存储受场地及季节性影响大，这些问题 都应该在预案里有明确的解决办法。今年秋收季节阴雨连绵，农民收秋受到很大影响，更给秸秆收储带 来不便。面对这一困境，滑县已经开始积极探索秸秆综合利用的新路径。今年以来，滑县就重点支持了 标准化秸秆收储中心建设、秸秆离田、农机具购置、秸秆饲料化项目。 田间堆积如山的秸秆与生物质电厂"吃不饱"之间的矛盾，折射出农业废弃物资源化利用之路仍充满挑 战。在滑县的探索中，我们看到了解决问 ...
