通过对１８３个土样分析。结果表明，我省山区主要稻田土壤钾素贮量一般较为丰富，但有效钾含量偏低，全钾、缓效钾等二种形态钾在不同土壤粒径上分布不尽相同，研究结果为通过耕作措施，促进钾素活化，提供依据。
Through 183 soil samples analysis. The results showed that the paddy soil in the mountainous areas of our province was generally rich in potassium reserves, but the available potassium content was low. The distributions of potassium, potassium and slow potassium in different soil particle sizes varied. The results were as follows: Tillage measures to promote activation of potassium provide the basis.
