Salinity Changes for Long-term Irrigation of Saline Water in Saline Soil in Xinjiang

新疆盐碱地长期利用盐水灌溉土壤盐分变化

PH affected soda saline-alkali soil adsorbing fluorine, the lower the pH, the more the fluorine adsorption amount and the less desorption rate.

pH越低，氟的吸附量越大、解吸率越小。

Classification and Evaluation of the Soda-saline Soil in Daqing

大庆苏打盐渍土壤的分类与评价

The study shows that salt-water change in field dimension of soda saline soil have the following features: high-spatial variation of salt content, exist of both saline and alkaline, poor hydraulic characteristic, and weak in transfer between soil water and groundwater.

研究表明田块尺度苏打盐渍土水盐变化具有如下特征：土壤盐分含量高度空间变异性、盐化和碱化共存，水力性质极差，土壤水和地下水的转化关系非常微弱。

Taking intensely saline soil as research site object in the area consisting of soda meadow saline soil, alkalized solonchak and meadow alkali soil in the Da'an Paleochannel, the aim to wash salt away from soil by planting rice with the process of irrigating and draining.

在大安古河道苏打草甸盐化土、碱化盐土和草甸碱土复区选择试验田，通过种植水稻，借助周期性的灌水、排水过程，溶洗土壤中的盐分，达到改良盐渍土的目的。

Soil saline classification showed that halomorphic soil was a kind of severe salinized soil, chernozem soil was a kind of non-salinized soil, and meadow soil was a kind of light salinized soil.

土壤盐化分级结果为，盐碱土属重度盐化土，黑钙土属非盐化土，草甸土属轻度盐化土。

This article emphatically discussed the improvement effect of aluminum sulfate on bad physical characteristics of soda alkali-saline soil.
