摘要
从钾元素的生物化学方面阐述了其重要性。描述了成都平原土壤钾含量特征 ,通过与全国土壤平均值及地壳克位值含量比较后得出低钾结论 ,并对成都平原土壤低钾含量的原因进行了分析 ,针对性地提出了改善土壤含钾量低的措施 ,为本区农业可持续发展 。
This paper emphasized the importance of potassium element as viewed from the aspect of biochemistry. The potassium element in the soil of Chengdu plain was characterized by low content compared with the average value of nationwide soil and with the Clarke value. The reason of low content potassium in the Chengdu plain soil was analyzed.In order to improved the low content of potassium in soil, we put forward some measures which are of significance in the sustainable development and improvement of output and quality of agriculture in Chengdu plain.
