土壤缺钾是导致我国农作物产量偏低、口质不高的主要原因。也是造成土壤板结的主要原因。长期以来,由于我国能用于生产钾肥的钾矿资源缺乏,钾肥长期依赖进口。到90年代中期,我国在利用丰富的不溶性钾矿生产钾镁肥的技术方面有了重大突破,其成果也列入了国家级星火计划重点... Potassium deficiency in the soil is the main reason for the low yield of Chinese crops and the low quality of the Chinese population. It is also the main reason for soil compaction. For a long time, due to the lack of potash resources in China for potash production, potash fertilizer has long been imported. By the mid-1990s, China made major breakthroughs in the technology of using abundant insoluble potassium to produce potassium and magnesium fertilizers, and its achievements have also been listed in the key points of the state-level Spark Program.
