Ideas about exploitation and utilization of saline soil resources 厚垫料肉鸡粪改良滨海盐土的研究
The permeability of saline soils is studied in laboratory 摘要对含盐土的渗透系数进行了室内试验研究。
In the same way , the defiled mind is cleansed through the proper technique 使用盐土、 ?水、牛粪干与适当的人力。
Many have a succulent growth form with swollen stems or leaves 有很多种类的盐土植物具有肥厚的茎叶,属于肉质植物。
Effects of phosphorus fertilizer application on the distribution of inorganic phosphorus fractions in a marine saline soil 施磷对滨海盐土无机磷组分的动态影响
Effects of coastal saline soils with different fertility on plant growth and development as well as physiological characteristics in cotton 不同肥力滨海盐土对棉花生长发育和生理特性的影响
The factors causing soil salinization include natural factors such as climate , hydrological and geological conditions , and human - made factors , such as irrigation patterns and cultivating system 盐渍化土壤类型主要为典型盐土、沼泽盐土、碱化盐土和干旱盐土。
Halophytes are adapted to obtain water from soil water with a higher osmotic pressure than normal soil water , so they need to be able to accumulate a high concentration of salts in their root cells 盐土植物的渗透压高于土壤,这样就可以从土壤中吸收水分,所以它们的根细胞中积累了高浓度的盐分。
Because of the evaporation , dissolved salt is brought to cumulate at the ground surface and the root zone when the ground water is above the critical level . then the saline soil is formed 超过临界深度的地下水,在蒸发作用下,将盐分带至地表或根系分布层累积下来,形成盐渍化土壤或盐土、碱土。
