近年来,由于我国农业生产坚持高投入、高产出的模式,耕地长期高强度、超负荷利用,导致土壤肥率下降,耕地质量退化,粮食产量和农产品供应面临挑战。加上化肥、农药等农资产品过量低效利用,以及工业“三废”无序排放,导致农田土壤综合质量退化,污染问题日益凸现,显现出退化、干旱、酸化、水土流失、结构不良等问题,对生态环境、食品安全、人体健康已经构成了严重威胁。专家指出,对农田土壤综合治理势在必行,让土壤恢复活力刻不容缓。为此,本刊从本期开始,开辟“让土壤恢复活力”专栏,从不同侧面介绍土壤恢复活力的观点、方式和方法,以引起人们的关注,并加入到土壤恢复活力队伍中来。欢迎有关人
In recent years, due to our country's agricultural production adhering to the mode of high investment and high output, the long-term intensive and overloaded utilization of cultivated land leads to the decline of soil fertility, the degradation of cultivated land quality, and the challenges of grain yield and agricultural product supply. Coupled with the excessive and inefficient use of agricultural and sideline products such as chemical fertilizers and pesticides, as well as the industrial “three wastes” of unordered emissions, the comprehensive quality of farmland has been degraded. The pollution problems have become increasingly prominent, showing degradation, drought, acidification, soil erosion, poor structure And other issues, on the ecological environment, food safety, human health has posed a serious threat. Experts point out that comprehensive management of farmland soil is imperative, so that the soil rejuvenate without delay. To this end, this issue from the beginning of this issue, open up “Let the soil revitalize ” column, from different aspects of the viewpoints, methods and methods of soil rejuvenation to attract people's attention and to join the soil to restore vitality team .
