吉林:“金色粮仓”扎根黑土地

"按照梨树模式种地,村里黑土地地力恢复了,玉米亩产2000多斤,每亩纯收入在1200元以上,大家觉 得生活越来越有奔头。"合作社成员、村民马云秋告诉记者。 用卢伟的话说,这几年黑土地质量越来越高,合作社成员的收入也是"芝麻开花节节高"。他介绍,合作 社成员从最初的6户发展到目前的180户左右,自有和托管(流转)的土地共有9000多亩,种植玉米加上 农机服务,户均年收入达七八万元。 而在十多年前,吉林包括梨树县在内的很多地方黑土地地力开始下滑。由于大量使用化肥,土壤中的有 机质越来越少,土壤板结的情况越来越严重,下雨后很容易形成内涝。农民们逐渐发现,即便用再多的 化肥,玉米产量也大不如前,这让他们忧心忡忡。 对此,四平、松原等地开始大面积尝试玉米秸秆覆盖免耕种植方式,逐步形成了梨树模式。由此,黑土 地地力逐步恢复,粮食产量稳中有升。以松原市前郭县为例,在该县525万余亩耕地中,黑土地面积达 430万余亩,大部分采用玉米秸秆覆盖免耕种植,结合水肥一体化等技术,玉米亩均产量达到2600斤以 上。 "黑土地保护来得太及时了!"卢伟感慨道,随着地力逐步恢复,稳定高产的玉米让村民们收入可观,长 远发展有了保障。 "要认真 ...

【新华社】黑龙江:让“沟碎地”变回“整块田”
Xin Hua She· 2025-07-30 00:33
盛夏的东北平原,沃野千里,绿浪翻滚。在黑龙江省海伦市前进镇光荣村,玉米田集中连片,郁郁 葱葱。难以想象,一年前这里还被一条深达1.5米、损毁10亩耕地的侵蚀沟割裂成两块。 "你看,脚下的土地就是曾经的沟壑,如今已平整如初,老百姓特别高兴。"中国科学院东北地理与 农业生态研究所副研究员郭明明站在田间,话语中透着自豪,"科技让'沟碎地'变回'整块田',不仅沟消 失了,而且这块土地几乎不会再受侵蚀。" 水土流失,是黑土地"变薄、变瘦、变硬"的重要诱因之一。大规模开发导致森林、草地等天然屏障 消失,土壤裸露。一场暴雨过后,表层黑土被冲刷,沟道不断扩张,威胁粮食生产安全。 "几年前光荣村受几十条侵蚀沟影响,3.2%的耕地被损毁。"中国科学院东北地理与农业生态研究所 教授张兴义说,"侵蚀沟不仅蚕食良田,更将地块切割得支离破碎,阻碍大农机作业,影响农业现代 化。" "黑土地保护要在利用中保护,既要多种粮,又要保生态。"张兴义说,东北黑土区侵蚀沟治理遵 循"三个优先"原则,优先治理耕地中的侵蚀沟,优先采用填埋复垦技术恢复耕地完整,优先推广植被为 主的柔性治理技术。 一项项"量身定制"的治沟技术展现出强大效能。坡度陡的沟岸,用 ...
