针对我国肥料农药高施低效的关键问题，以天然黏土为基础材料，建立了基于纳米网捕的化肥农药迁移阻控方法，研制出控失化肥和控失农药***并实现产业化。迄今，技术累计推广约2 亿亩，创造显著的经济、社会和生态效益，为我国肥料农药双减提供有效科技支撑，对于推进农业高质量发展和乡村振兴两大战略具有重要意义。

To solve the problem of “high usage and low efficiency” of fertilizer and pesticide, a novel approach to control fertilizer and pesticide migration based on nanonetworks was established. Then loss-control fertilizer and loss-control pesticide were developed and industrialized. Until now, they have been applied for 0.1 billion mu, showing huge economic, social and ecological effects. This work provides an effective approach to decrease amounts of fertilizer and pesticide, presenting significance on two strategies of agriculture high-quality development and rural revitalization.
