查询词典 cations

Soils from the study sites show the typical characteristics of an Andisol, being strongly acidic, with fewer exchangeable cations, a low base saturation, and an accumulation of soil organic matter with Al-compounds which are recalcitrant to decomposition. Therefore, the effects of vegetation types on the contents of SOM, TC, TN, and CEC were not significant.

In different degree of saline and alkali conditions controlled in lab or under field, contents as followed were determined: the absorption, transportation and distribution of major cations Na~+, K~+, Ca~(2+and Mg~(2+) in indicator plant; organic solute, and antioxidase activities, including superoxide dismutase, catalase and peroxidase POD characteristics of individual, population and community of the plant. Responses of the indicator plant to environment from physiological to community aspects were systemically discussed in this document.(1 Vegetional characteristics and edaphic indicators including bare patch index, dry biomass, percent cover by perennial plants, growth indicators of Leymus chinensis, soil organic matter and pH were sensitive to saline-alkali grassland degeneration.

运用室内控制和野外试验相结合的方法，调查和测定在不同土壤盐碱条件、不同季节里，主要元素Na~+、K~+、Ca~(2+)、Mg~(2+)在植物体内吸收、运输和分布的变化状况；研究不同土壤离子浓度下，指示植物体内渗透调节物质——脯氨酸和糖类、超氧化物歧化酶、过氧化物酶和过氧化氢酶活性等指标的变化响应情况；研究不同盐碱梯度下，植物个体、种群、群落的特征；系统的从生理生态角度探讨指示植物对盐碱环境的响应：(1)植被特征指标：裸地指数、生物量、多年生植物覆盖率；羊草生长状况指标：土壤有机质含量、pH可作为松嫩平原退化评价的指标。
