对话张福锁院士:土壤问题造成每亩每年100公斤粮食隐形损失
Xin Jing Bao· 2025-07-28 05:39
"人们关注土地的粮食产出,关注化肥、农药,但很少有人了解,土壤环境的不合理,使得每亩地每年 损失100公斤粮食,而我们的目标,是夺回这100公斤,并且让地越种越肥。"中国农业大学教授、中国 工程院院士张福锁团队首次将"植物-土壤反馈"理论引入农田生态系统,并揭示土壤"越种越好"的反馈 机制,该成果发表于《科学(Science)》杂志。近日,新京报记者对话张福锁,解读藏在土壤深处的 秘密。 化肥农药,不是洪水猛兽 新京报:能否介绍一下这项研究的初衷? 张福锁:土壤为人类提供了95%以上的食物,是人类生存所必需的食物与营养来源。人民群众对美好生 活的向往,首先就会体现在吃饭问题上,也就是从吃得饱向吃得好、吃得营养健康转变,只有健康的土 壤才能生产出优质健康的食物。但是对土壤的关注不足,使得土壤质量下降,形成了"投入越来越多, 地越种越馋,资源效率越来越低,作物品质和环境生态越来越差"的恶性循环。造成这种现象的根源在 于,当前的作物管理以产量为主要目标,长期忽视了农田管理措施对土壤的反馈效应,即"遗产效应", 导致土壤负反馈不断加大,正反馈缩小,土壤"遗产"不断缩减或者被耗竭,严重威胁耕地质量和农业可 持续发展。 ...
