作者于1984—1986年对不同母质的77个土样进行了一系列理化分析,并采用放射性~(86)Rb 示踪原子法研究钾在土壤中移动和固定。结果表明:我省石灰性土壤钾的含量丰富,供钾能力强,土壤速钾含量与有机质,缓效钾,粘粒含量之间相关密切。土壤质地,水分状况对钾的移动,固定有明显的影响。 In 1984-1986, a series of physical and chemical analyzes were carried out on 77 soil samples from different parent materials. The radioactive ~ (86) Rb tracer atomic method was used to study the movement and fixation of potassium in soils. The results showed that the potassium content of calcareous soil in our province is rich, and potassium supply is strong. There is a close correlation between the content of potassium in soil and the content of organic matter, slow-acting potassium and clay. Soil texture, water status of the movement of potassium, fixed obvious impact.
