| 摘要: |
| 土壤水溶性盐的含量与组成随制备浸出液的水土比例不同而异,对含石膏的盐渍土测定结果的影响尤为显著。为了正确反映田间水溶性盐的实际状况,作者进行了三种不同水土比例制备浸出液的对比试验。结果表明,适宜水土比为1:1,其测出的盐分含量与饱和泥浆法按近,且操作简便、快速,在我国一般土化分析实验室均可采用。 |

| SELECTION OF THE SUITABLE SOIL/WATER RATIO FOR TESTING OF SOLUBLE SALTS IN GYPSIFEROUS SOIL |
|
|
|
| Abstract: |
| In order to select the suitable soil/water ratio for testing the soluble salts in gypsiferous soil,the comparative tests were studied.The result showed: 1.The amount of soil soluble salts varies with the different soil/water ra- tios. 2.1:1 soil/water ratio is suitable for the determination of the soil soluble salts in gypsiferous soil.It is more simple and rapid than those of the saturated extraction. |
| Key words: soil/water ratio soluble salts gypsiferous soil saturated extraction |
