编者按目前,我国耕地退化面积已占耕地总面积的40%以上。据专家分析,我国耕地退化主要有两大原因:一方面是中国耕地基础地力后劲不足。另一方面则是土地污染加重的问题越发严重,包括工业废物污染以及农资投入品的污染。尽管造成耕地退化的原因众多,但不可否认,农资产品的过量投入是造成耕地退化的一个重要因素。有资料显示,我国总体化肥用量接近峰值,将来会迎来肥料零增长时代,零增长时代的到来对肥料技术研发、服务机制提升都提出了新的要求。众所周知,耕地
Editor’s note At present, China’s cultivated land degradation area has accounted for more than 40% of the total cultivated area. According to expert analysis, there are two main reasons for the degradation of cultivated land in our country: on the one hand, insufficient stamina on the basis of China’s arable land. On the other hand, the problem of aggravated land pollution is aggravated, including pollution of industrial waste and pollution of agricultural inputs. Although there are many reasons for the degradation of arable land, it is undeniable that over-investment in agricultural products is an important factor contributing to the degradation of cultivated land. Data show that the amount of fertilizer in China is close to the peak in the future will usher in zero-growth era of fertilizer, zero-growth era of fertilizer technology research and development, service mechanisms have raised new requirements. As we all know, cultivated land
