soil water stress的意思|示意

The growth of root was restrained and activity of root decreased under severe water stress ( water content of soil is 35% the content of field holding water).

但重度水分胁迫（土壤含水量为田间持水量的35％）抑制根系的生长，根系活力下降；

Water stress can decrease the availability of soil nutrients.

水分亏缺可使土壤养分的有效性降低。

Pore water pressure in soil will change the effective stress of the soil;

孔隙水压力会改变土体中的有效应力；

Soil water-stress led by longer drought in summer could also influence soil respiration rate obviously.

长时期夏季干旱造成的土壤水分胁迫也明显影响土壤呼吸速率；

Experimental results show the typical characteristics of soil liquefaction: excess static pore-water pressure increases, effective stress decreases, and volumetric strain increment increases.

试验结果验证了砂土液化典型特征：超静孔隙水压升高，有效应力降低，体积压缩积累增大。

The effects of soil water stress on membrane protective system and membrane lipid peroxidation in 3-year-old Taxus media cv.

以引种栽培的3年生曼地亚红豆杉为材料，研究了土壤水分胁迫对叶片膜保护系统和膜脂过氧化作用的影响。
