初步探讨了消煮时间、沸腾时间对土壤缓效钾测定结果的影响程度及其规律,确定了最佳沸腾时间为3 .5 ～4 .5 分钟,同时掌握了相同条件下,消煮5 分钟与10 分钟土壤缓效钾测值间的相互关系。
The effects of boiling time and boil time on the results of soil slow-acting potassium determination were discussed preliminarily. The optimum boiling time was 3.5 ~ 4.5 minutes, and under the same conditions, And the 10-minute soil slow-acting potassium correlation.
