根据农业部土壤养分监测分析可知,当前全国耕地质量明显下降,其中耕地土壤有机质含量偏低,平均仅1.8%,旱地仅为1%左右,与欧美等发达国家的地力水平差距较大。施肥不当是主要原因,必须引起重视。长期以来,技术与物资脱节,化肥产、供、施畸形发展,施肥技术落后,施肥比例严重失调,出现“三重三轻”现象,即重化肥,轻有机肥;重氮肥,轻
According to the Ministry of Agriculture soil nutrient monitoring and analysis shows that the current national quality of cultivated land decreased significantly, of which farmland soil organic matter content is low, an average of only 1.8%, dry land is only about 1%, with Europe and the United States and other developed countries a greater gap between the level of geotechnical. Improper fertilization is the main reason that must be taken seriously. For a long time, the technology and materials are out of line with each other. The development of fertilizers production, supply and application of deformities has lagged behind and the fertilization technology has lagged behind. The proportion of fertilizers is seriously imbalanced, resulting in the phenomenon of heavy and chemical fertilizers and light organic fertilizers.
