摘要/Abstract

摘要： 硫氧化细菌具有氧化单质硫及硫化物，生成硫酸的特性。根据硫氧化细菌的这种生物特性，使其在盐碱土中发生生化反应，将硫磺粉氧化生成硫酸，中和盐碱土中的OH^-，从而达到改良盐碱土的目的。在实验中，土样分为吹填土、盐田土、农田土、绿化土4组，将一定体积的氧化硫硫杆菌、排硫杆菌菌液和硫磺粉加入到各土样中，每12 h观测一次土壤上清液的pH值和电导率。实验结果表明:氧化硫硫杆菌和排硫杆菌对降低土壤pH值有明显作用，使土壤pH值由7.5降低到7.2，对改良碱土有一定的作用。

关键词: 盐碱土, 硫氧化细菌, 氧化硫硫杆菌, 排硫杆菌

Abstract: The sulfur-oxidizing bacteria have a characteristic of oxidating sulfur and sulfide into sulfuric acid. With the biological characteristic of sulfur-oxidizing bacteria, sulfur is oxidized into sulfuric acid which neutralizes the OH^-, so as to achieve the purpose of improved saline-alkali soil. The authors use four types of soil experiment, such as dredger fill, salina soil, farmland soil and green soil. Put certain volume of thiobacilus thiooxidans, thiobacilus thioparus and sulfur into the soil samples, then detect the pH and conductivity of the soil supernatant fluid once per 12 hours.The result shows that the thiobacilus thiooxidans and thiobacilus thioparus have significant effect to lower the pH value of soil from 7.5 to 7.2, have effect on improving the saline-sodic soil.

Key words: saline-sodic soil, sulfur-oxidizing bacteria, thiobacilus thiooxidans, thiobacilus thioparus
