Effect of leaching on the secondary aluminum sulfate improved Sodic Soil : This study Songnen Plain region before Guo severe saline soil for the study, in the form of laboratory simulation analysis , improved after adding aluminum sulfate , and then rinsed the results were analyzed . Add aluminum sulfate were selected concentrations of 0 %, 0.2 %, 0.4 %, 0.6 %, 0.8 %, 1.0 %, 1.2% was measured , which was studied in seven cases were rinsed once , twice, three times, soil the ion concentration in the solution and the major trend , and the physical properties of the seven concentrations were measured after the addition . Integrated the test results , the following conclusions .
Rinse effectively improve the salinization of the soil . In certain amount of aluminum sulfate , the increase in the number of rinsing with a concentration of sulfate ions and anions such as chloride ion decreased significantly . Carbonate and bicarbonate have decreased significantly, but the impact of carbon dioxide in the air by the rate of decline is not fast sulfate and chloride ions , but also significantly improves the ion results of the soil, the soil is more suitable for crop growth .
Leaching significantly improve soil chemical composition role, but added to the leaching of aluminum sulfate as there are a lot of time, while in shock and so on, for the first time put into hydrocolloids aluminum sulfate , aluminum sulfate partially formed have been destroyed affected the improvement effect of aluminum sulfate to the soil . Meanwhile, rinse the shock process also destroys any original soil aggregates and micro-aggregates , rinsed several times so that the physical properties of the soil does not improve, or even have a negative effect in terms of pH value of the soil solution .
When no leaching the soil , add aluminum sulfate to effectively improve soil properties , especially for reducing soil alkalization degree , the effect is obvious. Soil pH, soil bulk density, soil particle size and other aspects of the role of soil have been improved , and the effect is obvious. Calcium and magnesium ions with the addition of aluminum sulfate was released from a certain extent, also played a role in reducing the degree of soil salinization . However, the use of aluminum sulfate improvements alone , and can not fully solve the problem of soil Songnen Plain . Increase the salt content of the soil material when there is higher due to soil salinization degree , aluminum sulfate did not improve soil salinization of the problem , and even add aluminum sulfate. Therefore , only the aluminum sulfate soil type conversion from soda type of sulfuric acid type , the problem is alleviated, but not completely resolved.
Integrated aluminum sulfate and leaching the pros and cons of these two methods improved , improved ways of combining the two , you can get both the basicity improve soil problems, but also can improve the problem of salinization of the soil , the better the improvement of soil conditions. When adding aluminum sulfate to 0.8% , leaching the soil twice , the researchers noted that the best results can be achieved .
