行走美丽画卷|宁夏贺兰:“稻渔共生”走出生态农业新路径

探索‘以渔治碱’模式,推进黄河流域生态保护和高质量发展

Quick Look

宁夏贺兰县针对引黄灌区盐碱地问题,大力推广“稻渔综合种养”与“以渔治碱”模式。通过立体循环种养改善土壤结构,将盐碱荒滩变为稻丰鱼肥的良田,带动农户增收,为黄河流域生态保护提供可借鉴样本。

Why It Matters

贺兰县地处银川平原引黄灌区腹地,长期引黄灌溉导致地下水位抬升及土壤盐碱化。

2020年6月,习近平总书记在宁夏贺兰县考察时说,要注意解决好稻水矛盾,采用节水技术,积极发展节水型、高附加值的种养业,保护好黄河水资源。

贺兰县地处贺兰山下、银川平原引黄灌区腹地。这里干旱少雨、蒸发旺盛,叠加长期引黄灌溉抬升地下水位,盐分随水分蒸发不断在地表富集,大片土地沦为盐碱荒滩,土壤含盐量高、土地产出效益低。

近年来,当地大力推广稻渔综合种养、“以渔治碱” 模式,通过在稻田中开挖沟渠养殖鱼、蟹、鸭等水生动物,构建起自然循环的种养生态系统:水稻为水生动物提供遮阴环境和天然饵料,动物的活动不仅能疏松土壤、捕食害虫,其排泄物还可作为水稻的有机肥料。这种“稻渔共生”的立体循环种养系统改善了土壤结构,让白碱滩蜕变为稻丰鱼肥的丰产良田。昔日的普通村落也变身的生态打卡地,当地农户完成了身份转变,被“编”进了农旅融合的产业链,收入不断提高。

贺兰县的“稻渔共生”实践为黄河流域生态保护和高质量发展提供了可借鉴的“塞上样本”,不仅是对“绿水青山就是金山银山”理念的生动诠释,更昭示着黄河沿线地区只要立足资源禀赋、遵循生态规律,就完全能够走出一条生态美、产业兴、百姓富的可持续发展之路,让黄河真正成为造福人民的幸福之河。

Open Questions

  • 该模式未来能否大面积推广至其他黄河流域盐碱地?
  • 参与种养的农户具体年增收额度是多少?

[Praise for China] The fertile fields of golden autumn surge with "harvest waves", and smart agriculture plays a new chapter in the granary of a great country

my country's autumn grain harvest progress has exceeded 40%. Various regions have greatly improved harvesting efficiency and land protection levels by promoting technologies such as smart agricultural machinery, cross-regional operations, and straw return. The popularization of the smart agriculture model not only reduces food loss, but also ensures farmers' income through order planting and consolidates the foundation of food security.

Warm and dry autumn calls for attention to leafhopper, thrips and moth control

The Tainan District Agricultural Improvement Center pointed out that the warm autumn and dry climate has increased the risk of small pests such as southern spotted leafhoppers, thrips, and moths in the mid-growth period of groundnut growth. Southern spotted leafhoppers can spread leaf cluster disease and affect flowering and fruiting. Thrips damage young leaves and flower organs and reduce the pod setting rate. When moth larvae eat leaves and pods, they eat all the leaf flesh. It calls on farmers to prevent and treat the disease early and refer to the plant protection information system to select registered pesticides.
