中新网三沙8月18日电 题:在南海看见森林——我国南海岛礁生态环保建设取得显著成效 作者 何铁城 贺跃民 张大禹 航行在祖国南海,座座岛礁上郁郁葱葱的森林,像一颗颗墨绿色的明珠,点缀着翠绿色的礁盘,令人心 驰神往。经过一茬茬官兵的辛勤努力,曾经被称为海上戈壁的南海岛礁已全部完成绿化覆盖,以"绿色 岛礁、生态岛礁"为建设目标的珊瑚岛礁可持续发展取得亮眼的成绩。 这是2025年6月29日在南海某岛礁拍摄到的画面,礁上茂密的绿色植被取代了原本白茫茫的礁砂,与周 边蔚蓝色海面形成鲜明对比。 张大禹 摄 "树是岛礁的生命",这是岛礁官兵挂在嘴边的名言,也是刻进他们心头的理念。南海岛礁常年高温、高 湿、高盐,加上珊瑚砂养分少,缺少有机质土壤,一般植物很难存活。官兵们接力探索改良土壤,筛选 出草海桐、木麻黄等耐高温、抗大风、适应南海气候的植物,找到了凤凰木、长春花特色植物的种植维 护方法,岛礁平均植被覆盖率达46%。 在某岛礁,官兵培育的植物种类已达120余种,植被覆盖率超过90%,成片的木麻黄林、抗风桐林、大 叶榄仁树林鳞次栉比地分布在各个角落,林下土壤表层出现了落叶和枯草形成的腐殖质,乔、灌、草衔 接互补的森林植物群落 ...

盛夏的清晨,在河南省新乡市新乡县小冀镇高标准农田里,河南农业大学科技小院指导老师赵亚南在玉 米地里,俯身注视着一条条黑色滴灌带。"轻按这个开关,水肥混合液就能顺着滴灌带精准送到玉米根 部。"赵亚南一边向种粮大户李绍林演示操作,一边叮嘱道:"现在玉米正处在抽雄关键期,水肥要喂得 及时又精准。" 田间的滴灌带如同密布的"毛细血管",每隔30厘米就有个针眼大的小孔,晶莹的水滴裹挟着养分缓缓渗 出,沿着土壤缝隙渗入玉米根系。李绍林流转的500余亩地里,玉米、大豆错落生长,滴灌系统正有条 不紊地作业。"往年大水漫灌,不仅费水,高温天气还容易让根部受涝。现在用这浅埋滴灌,在设备全 部开启的情况下3天就能把所有地浇一遍,而且能节省一半的用水量。"李绍林扒开土层说,"你看这墒 情,玉米肯定能长好。" 在新乡县,滴灌技术只是抗旱保苗的利器之一。沿着人民胜利渠畔的田埂前行,只见黄河水顺着新修缮 的支渠分流到翟坡镇农田。种粮户郑纪昌站在渠边,看着水流漫过干裂的田垄。"前两天玉米叶子卷得 像麻花,引黄河水浇了两天,现在你再看这叶片,又挺又绿!"郑纪昌指着自家玉米地说,"往年靠井 灌,电费成本高不说,遇上旱情还得排队。现在河灌加井灌, ...
