●四川是全国13个粮食主产省份之一和油菜第一大省，"减肥"压力大 ●四川启动的绿色种养循环农业试点，重点是向有机物要肥料、向技术要质量、向机制要作为 ●科学施肥是四川农业"减肥"的主要方式，不再单纯追求量的减少，转而聚焦效的提升 每亩地的化肥用量，比10年前减少2斤，但德阳市中江县种粮大户常滔说，这个施用量并不影响粮 食产量。 截至2024年，四川化肥用量已连续8年减少。同期，全省粮食产量却一路攀升——2020年，时隔20 年再次迈上700亿斤台阶，此后一直稳定在700亿斤以上。去年，四川粮食总产量达到726.8亿斤，创历 史新高。 连续多年的"减肥"不减产之下，四川农业的"减肥术"初见成效。 两难考题 面临推动农业绿色发展和保障粮食安全双重使命 此外，在农业绿色发展背景下，农产品消费端从"吃饱"到"吃好"的导向更加明显，而以化肥为主的 投入品施用量，成为衡量农业绿色化水平和农产品品质的重要指标。 难做的原因只有一个，就是农产品稳产增产的压力。近年来，我国不断鲜明重粮政策导向。2020年 以来，四川陆续启动粮食安全党政同责考核、同步提升种粮补贴标准，剑指粮食播面稳字当头、粮食产 量稳中求进，助力端牢"中国饭碗 ...
