| 1. | Investigation and analysis of the salt content in the soil of road shoulder in yingkou area 营口地区公路路肩土壤含盐量的调查与分析 |
| 2. | Study on the correlation of soil salt content with electric conductivity and soil water content 土壤含盐量与土壤电导率及水分含量关系的试验研究 |
| 3. | The results made clear that soil salt increased after saline water infiltration and decreased after fresh water infiltration 结果表明,不同轮灌条件下,土壤含盐量随灌溉咸水而增加,随淡水灌溉而降低。 |
| 4. | The result of path coefficient analysis is that the factor affect net photosynthetic rate of h . ammodendron mostly is soil salt contents 通径分析结果表明,对退化梭梭净光合速率影响最大的生境因子是土壤含盐量。 |
| 5. | The inferred water quality , soil salinity and hydrogeologic units are quite consistent with what is said in the hydrogeologic reconnaissance report 所推断的水质和土壤含盐量与大的水文地质单元和1 : 20万水文地质普查报告都吻合得很好,且细节更为清楚。 |
| 6. | The sensor in the paper has also with the character . in order to ensure the interferefering factor , the examination of the temperature effect , the earth kind , the saline earth are done in the paper 为了确定传感器在输出时的干扰因素,分别做了温度对传感器输出的影响、土壤种类对传感器输出的影响、土壤含盐量对传感器输出的影响等试验。 |
| 7. | The results indicated that even if there was different at initial soil condition , such as initial moisture content and initial salt content , salt content in soil profile and sar at top soil increased greatly after the high salinity water infiltrated 结果表明尽管土壤初始条件存在差异,但灌高矿化度水后,土壤含盐量和溶液浓度总体增加,且土壤剖面特别是表层的sar明显增大。 |
| 8. | The results were as follows : 1 . on the basis of saline water infiltration , the characteristics of movement of soil water and salt under different cumulative infiltration were studied . the results indicated that when the salinity of the infiltration water was 3g / l , the top soil was desalinized and salt accumulated at the wetting front 通过对不同入渗水量下土壤水盐运移规律的室内模拟试验研究,结果表明利用矿化度为3g l水入渗后,土壤从上至下逐渐脱盐,上层土壤含盐量略低于土壤初始含盐量,中间土层基本保持土壤初始含盐量值,但湿润锋附近发生突变,含盐量达最大值。 |
