央视网消息：位于淮河岸边的安徽省阜南县蒙洼蓄洪区，曾经饱受水患困扰。近年来，当地依托水资源和地理环境，把水患变成水利，引 导村民在蓄洪区的低洼地里发展起了芡实、莲藕、水生蔬菜等适应性产业。这段时间，这里的4000多亩芡实陆续开始采摘。 记者在阜南县老观乡康湖村的一处芡实种植基地，硕大的芡实叶把水塘铺得满满当当，大大小小的芡实叶如同一个个绿色的圆盘，仿佛为 田野铺上了绿色地毯。 这个芡实种植基地总面积有4000多亩，以前是以种植小麦水稻为主。但是因为地处蒙洼蓄洪区，地势低洼，过去水患频发，容易积水，种 植小麦水稻时时常受到涝害影响，产量不高。顺应自然规律，近年来，当地通过调整农业种植结构，大力发展适应性农业，因地制宜发展适合 在低洼地种植的作物。比如说芡实，它是一种水生植物，营养价值高，市场需求旺盛。像记者现在所在的这个芡实种植基地，亩产可达600斤 左右，每年亩均产值6000多元，而且采收期也带动村民的劳务收入显著增长，部分群众通过流转土地和务工实现人均年增收3万多元。变水患 为水利，变对抗为适应，曾经被水患困扰的土地现在成了人们的"致富田"。 草木葱郁的长江公园、错落有致的休闲景观、充满活力的骑行步道……如 ...
