业内人士分析 ,我国化肥产业存在十大结构问题 :(1)磷少、钾缺、氮饱和。进口二元、三元肥以补磷、钾的缺口 ,又进一步加重了氮饱和程度。(2 )低浓度的、对生态有影响的化肥占一半以上 ,早就进入了淘汰期。(3)通用肥多 ,专用肥少 ,生物肥、生化有机肥更少 ,不适应生态农业产业 According to industry analysts, there are ten major structural problems in the fertilizer industry in China: (1) Phosphorus deficiency, potassium deficiency, and nitrogen saturation. Imports of binary and tertiary fertilizers to make up for the gap between phosphorus and potassium have further increased the level of nitrogen saturation. (2) Less than half of the chemical fertilizers that affect the ecology have already entered the elimination phase. (3) General fertilizer, less special fertilizer, less bio-fertilizer and biochemical organic fertilizer, not suitable for ecological agriculture industry
