（原标题：科技让种植规模挣脱人力束缚（念念有余）） 谈及耕地种植规模，新疆伊犁一位种植大户测算过，一个员工最高能打理1600亩耕地，这一规模的上 限，是当前滴灌技术条件下，单人管理的合理阈值。 这与我儿时记忆中彻夜守水浇地的农耕场景，形成了跨越时代的强烈对比。种植规模的提升，核心是管 理能力的突破，而现代化器械与智能软件，正是这场变革的关键推手。 儿时的农耕记忆，满是劳累的窘迫。那会儿浇地全靠拖拉机带动水泵，水管铺展、水量调控全凭人力， 为了不错过灌溉时机，大人常常要在田埂上守整夜，收放几十米长的水管时，弯腰弓背拉扯半天，累得 直不起腰。再往前追溯，更原始的桔槔吊水方式，一人一天忙活下来，也浇不了一亩地。彼时的种植规 模，完全被人力绑定，"人均两亩"几乎是绕不开的天花板。即便是后来有了简单机械，漫灌模式下的沟 垄易坍塌、水资源跑冒滴漏等问题，仍让种植规模难以突破，普通农户能管好十亩地，就已是相当不错 的水平。 以前每逢采棉花季节，往新疆去的火车上坐满了采棉工，采棉工的数量直接决定了可管理面积。当地政 府每年都要费力找采棉工，政府机关和学生每年都要下田地采棉花。如今随着采棉机普及，这一场景成 为历史。 一位长期 ...

节水从来不只是应对资源短缺的权宜之计，而是关乎可持续发展的持久命题。 20世纪70年代后期，中国开始把厉行节约用水作为一项基本国策。几十年来，节约用水不仅是贴在墙上 的宣传标语，也培育出一个体量庞大的市场。 根据水利部发布的最新消息，中国节水产业蓬勃发展，农业、工业、城镇生活、非常规水等领域涌现出 一批龙头企业，各地新建成多个节水产业园区，相关产业市场规模估算超过7600亿元。 节水产业的发展，源于中国水资源短缺的客观压力。 中国水资源时空分布不均，加上人口众多，因此，人均水资源占有量远低于全球平均水平，这样的形势 决定了中国必须走节水之路。 近年来，中国出台《国家节水行动方案》，将节水纳入地方考核体系，不断促使节水从理念转化为行 动。日渐成熟完善的机制，进一步打开了节水产业的发展空间。 在日常生活中，节水同样发生在大街小巷。在不少城市，智慧水务系统改变了传统的供水模式。通过成 千上万个智能水表传回的数据，调度中心可以精准感知整座城市的用水脉搏。在"智慧大脑"加持下，一 旦有供水管道发生泄漏，系统会立即发出提醒，维修人员可以直奔现场，减少不必要的水资源浪费。 节水，也不断催生出新的商业模式。合同节水管理的应用 ...
