土壤吸湿水测定方法的改进

以土壤吸水湿水常规测定方法为依据，设置新的烘干温度和时间组合。对不同类型土壤样品进行重复试验，其测定结果与常规方法比较，具有测定时间缩短，测定数据重现性好，节能降耗等特点。适于生产、科研批量样品的测定，以及各层次农林院校土壤学课程教学应用。

The Improvement on the Determining Method of Hygroscopic Water of the Soil

Based on the conventional determining methods of the hygroseopic water of the soil, the new stoving temperatures and time combination were set up in the study.It has been shown that this new determining method had the following characteristics as shorter determining time,better repeatabelity of the determining data as well as economizing on resources & reduing consumption after the repeat tests on various types of soil samples and the comparison between the deternined results and the conventional methods, so it would fit well both the determination of batch samples in production and scientific research and the courses of soil socience in various universites and colleges.
