长期以来,我国农业都是以高投入、高产出的模式进行生产,耕地长期高强度、超负荷利用,导致土壤肥力下降,耕地质量退化,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。下面是我国相关部门,以及专家老师对耕地土壤状况的调查研究报告内容。 For a long time, China’s agriculture is produced in a high-input and high-output mode. The long-term high-intensity and over-utilized cultivated land leads to the decline of soil fertility and the degradation of cultivated land. Coupled with the excessive and inefficient use of agricultural products such as fertilizers and pesticides , And the disorderly discharge of industrial wastes have led to the degradation of the comprehensive quality of farmland soils and the pollution problem has become increasingly prominent. The following is the relevant departments of our country, as well as experts and teachers on the state of arable land survey report.
