查询词典 wilting point

At permanent wilting point the water pote- ntial of the soil is equal to or lower than the water potential of the plant.

在永久萎蔫点，土壤中潜在的水势等于或低于植物细胞的水势。

The lower limit of water availability is thus determined by the physiology of the plant species and is known as the permanent wilting point – the soil water content at which plants wilt and are unable to recover.

因此可利用水的下限是由植物物种的生理特性所决定的，被称为永久萎蔫点——土壤水含量在这个点上，植物枯死，不能恢复。

The relation between the wilting point with the soil physics characters as clay content,organic matter content and the salt content have been studied based on the experiments in field.

基于清徐大田土壤试验研究了土壤的凋萎系数与其土壤物理性粘粒含量、有机质含量以及土壤全盐含量之间的关系。

Less than 5% of the total water retained in WASRNF is non-freezing water which is equivalent to water which is inferior to permanent wilting point of soil, and difficult for plant use.

保水缓释氮肥的结合水占5％以下，其相当于土壤吸湿水，是植物难利用水。

Permanent wilting point The point at which soil has dried to the extent that plants can no longer remove the remaining water held on the soil particles,and begin to wilt and will not recover,even if moved to a cool,dark place,unless more water is added to the soil.

永久萎蔫点：指土壤干旱的程度足以引起植物不再能从土壤中吸收水分，开始凋萎，即使是将其移到阴凉、黑暗的地方，也不能再次恢复，除非给土壤中添加更多的水。

For gully cliff, soil moisture was close to wilting point, which was the driest soil in a gully watershed.

The permanent wilting point is reached when the plant has wilted to a point where it will not recover, even if more water is added, because the cells have plasmolyzed.

当植物的萎蔫达到一定程度就不可以再复原，这一极限被称为永久萎蔫点。超过此极限，补充再多水分也不能被吸收，因为已经胞质浓缩已经到达质壁分离的程度。

Planted vegetation, especially more than 20 years old planted trees and planted grasses consumed much more soil water than vegetation in natural restoration, and the soil water content in 200-500cm soil layers was almost near to wilting point.
