盐渍土

Salt tolerance of Suaeda salsa and its soil ameliorating effect on coastal saline soil was studied through a brine soaking experiment.

试验研究了碱蓬的耐盐能力及其对滨海盐渍土的改良效果。

The research proved that Tamarix chinensis was a kind of plant with significant salt tolerance capability and it had remarkable effects on the improvement of coastal saline soil.

结论］柽柳是一种耐盐能力很强的盐生植物，对滨海盐渍土具有明显的改良作用。

Though the comparison between the experimental group and the control group, it was proved that planting Tamarix chinensis on the saline soil not only could increase the number of the soil micro-organisms, but also could increase the volume of air, the content of organic matter, and lower the pH value, increase in ornamental.

通过将实验组与对照组的比较，分析得出在滨海盐渍土上栽植柽柳不但可增加土壤中微生物的含量，而且可增加土壤中的空气和有机质的含量，提高土壤颗粒的贮水能力，还可降低土壤的pH值，增加观赏性。

Once the characteristics for surviving salty soil are known, Flowers and Yeo will try to breed the appropriate genes into all manners of crops and plants.

一旦特点，为幸存的盐渍土是众所周知的，鲜花和杨荣文将努力培育合适的基因都礼貌的庄稼和植物。

For example, it can be easily stated that this result will play a key role for distinction of saline soil and sandy soil on the satellite images due to the absorption in long spectral bands for lower soil layers of CSS.

例如，它可以很容易地指出，这一结果将起到关键作用的区别盐渍土和沙质土壤上的卫星图像，由于在长期的吸收谱带较低土层的CSS 。

Not only is the frozen-heave rate of salty soil relevant with the temperature, but also there is great linear relation with water content, soluble salt content and silt content.

冻胀率不但与温度有关，而且与含水量、易溶盐含量、粉粒含量有很好的线性关系，可用线性方程初步估算盐渍土的冻胀率。

With tabia which is composed of saline soil, lime and crushed stone as an example of backfill engineering, a series of experiments of physical and mechanical properties were carried out to investigate the compressive strength and contributing factors of tabia.

以由盐渍土、石灰、石子组成的材料对地基进行回填处理工程为例，通过一系列三合土物理力学性能实验，分析了三合土的抗压强度以及影响因素。

It is suggested that policy should be on the basis of minimum irrigation, soil mulching and straw and manure utilization, and the leading one of its measures should be to use high-salined groundwater as an accompaniment of river water, by the integration of the power-pumped-Yellow-River irrigation system and well-water irrigation system, to lower the watertable and reduce the irrigation cost. Thus the dynamic balance of salts, as well as the prevention and reclamation of salinization, will have been kept through the management of water and soil organic matter.

在此基础上结合国内外盐渍化防治及盐渍土改良利用方面的发展趋势，笔者提出应该以水盐平衡理论为指导，以节水灌溉为前提，以地面覆盖和土壤培肥为基础，以井排系统与引黄灌水系统并网，井渠混灌，降低地下水位为突破口，通过对水分和肥力的调控和管理达到对盐分的调控和管理，使盐分在土体或灌区实现动态平衡，从而达到土壤盐渍化的预防和治理。

There are thinks the double features of saline and alkaline for the formation and evolutionprocess of the salinization soils in this region,the generation intensity and scale are related withgeomorphological types,shallow water geochemical types,shallow water table and soil structureetc.,presents the quantity relationship between the salinization degree of the soils,shallow watertable and mineralization,expounds the four stage and seasonal succession features of slattransference and inversion,discuss the interaction between ions in shallow water and soils and thethe regularity of the salt transference and accumulation under freeze-thaw action.

本文在野外调查、监测及实验研究的基础上提出松嫩平原盐渍土的形成过程存在盐化与碱化双重作用，其发生强度和规模与地貌、潜水类型、径流条件、潜水水位、土壤结构有关，提取出潜水埋深、矿化度与土壤盐渍化程度关系的定量指标，以及土壤盐分迁移转化季节性变化的四个阶段及其特征。同时重点研究了潜水与土壤之间元素交互作用及冻融作用下盐分迁移和聚积规律，为土壤次生盐渍化的防治提供了理伦依据和技术支撑。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
