| 1. | Salinity refers to the total concentration of salts present in the soil solution . 含盐量是指土壤溶液中所存在的盐类的总浓度。 |
| 2. | Drainage water analyses may not indicate the composition of soil solutions accurately . 排水分析不能正确地反映土壤溶液的组成。 |
| 3. | Determination of oxygen content in forest soil solution 森林土壤溶液中氧含量的测定 |
| 4. | The extent of infection is controlled not by the phosphorus concentration in the soil solution but the phosphorus content of plant 植物所吸收的磷以聚磷酸盐的形式在菌丝中运输效率高 |
| 5. | Acidity and inorganic nitrogen concentrations in soil solution in short - term response to n addition in subtropical forests 鼎湖山森林土壤渗透水酸度和无机氮含量对模拟氮沉降增加的早期响应 |
| 6. | The mineral elements from the soil that are usable by the plant must be dissolved in the soil solution before they can be taken into the root 土壤中可供植物利用的矿物成分,必须溶解在土壤中才能被根部吸收。 |
| 7. | Most research results indicated that temperature has the effects on concentrations of dissolved organic matter in soil solution and on composition of soil organic p 大多数研究结果显示,温度对土壤溶液中的溶解态有机质和土壤有机磷组分有较大的影响。 |
| 8. | In tropical and sub - tropical area , soil solution contains large amount of hydroxy - fe ions . these hydroxy - fe ions may react with montmorillonite in soils to form fe - oxyhydioxide - monuiiorillonite complexes 它们可以和负电性的土壤矿物?蒙脱石作用生成低聚合羟基铁?蒙脱石复合体。 |
| 9. | Ions ( mainly refering to ca2 ' , mg2 * and ncv et al . , which have higher concentration in soil solution ) in rape rhizosphere with no re and appropriate dose re treatments moved mainly via a diffusion process up to a 3mm distance from the central compartment ( c . c ) , and mainly by mass 油菜对照和低浓度稀土处理距根表3mm以内离子(主要指ca 》 、 no 。 w等在土壤溶液中浓度较大的离子)迁移以扩散方式为主, 3mm以外的区域则以质流方式为主。 |
| 10. | Equilibrium distribution of an ion between soil solution and solid phase was described by a distribution coefficient , k . the k was a ratio of cs and c1 and a conditional equilibrium constant , which cs and c were quantity of k in solid and solution phase respectively 随水吸力增大,固相钾离子( cs )比率下降,液相钾离子比率逐渐增加,分配系数k减小。在水吸力约为1 . 5 10 ~ 5pa时,四种土壤钾离子在固液相间的分配达到稳定,分配系数为最小。 |
