根系吸收 meaning in Chinese
radicular system absorption
Examples
- During the day water loss by transpiration exceeds water absorption by the roots, and leaf water potential decline .
白天蒸腾作用散失的水分超过根系吸收的水分，因而叶子的水势就下降。 - Effect of root absorption properties of tea plant on pesticide residues in tea
茶树根系吸收对茶叶中农药残留的影响 - It is absorbed by plant roots as the potassium ion , k + , and in plants is the most abundant cation in the cell sap
以钾离子k +的形式通过根系吸收，在植物中是细胞液里最丰富的阳离子。 - In the course of intensive evaporation , the convergent zero flux potentials may occur at depths where the main roots of most plants develop . what ' s more , the capacity of flowing water at the depth is not zero , and it equals to the water absorbed by the root of the plants
在蒸发强烈的季节，主要植被根系发育的主要地段往往形成收敛型零通量面，水分向这些地带汇集，汇集的水量接近根系吸收的水量。 - In field study , the expenment on nitrogen transport and transformation in soils with different irrigation ( with both ground water and sewage effluent ) and fertilization levels has been conducted . with considenng the n - uptake , nitrification and demtrification processes , a model for describing no2 - - n transport and transformation in unsaturated soil has been applied . results show that , the n03 + - n accumulating in soil is contributed more by fertilization but lees by irrigation with sewage effluent , and the model can be used to simulate no3 - - n transport in soils
在室外进行了不同清污水灌水量与施肥条件下氮素迁移转化试验，同时进行了考虑根系吸收，硝化和反硝化的田间非饱和no _ 3 ~ - ? n迁移转化模型的数值模拟，研究结果表明与施肥相比，污水灌溉对土壤中no _ 3 ~ - ? n累积的贡献较小，所建立模型可用于模拟no _ 3 ~ - ? n在土壤中的迁移。
