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.

( 4 ) Other types of non -alcoholic drinks : 0.04% -0.05 % according to the ratio of addition of sorbic acid .
In the production of sweet wines , sorbic acid is often used as a preservative in use. Sorbic acid antibacterial effect only in synergy sulfur dioxide will play a greater role . Allows the use of sorbic acid in the national standards , but should pay attention to in the course of the highest limits , not excessive . Also, pay attention to the relationship between sorbic acid and sulfur dioxide, alcohol , and to maximize the preservative sorbic acid . Sorbic acid is an unsaturated fatty acid , non-toxic , can be completely absorbed . It has a special role in the anti- yeast , a fungus inhibitor stable ; its ability to inhibit the propagation of wine yeast , is more efficient in the inhibition of the absence of air ; can inhibit the ability of the yeast fermentation of sugar without killing them. National standard ” wine ” in the provisions of GB15037-2006 the maximum allowable amount of 200mg / L, inspection agencies at all levels can be detected in the presence of sorbic acid and measured its dosage . But note that some countries do not allow the import of sorbic acid -treated wine , therefore , in the production of export products must pay attention and understand clearly . Sorbic acid resistant yeast capacity because of the presence of ethanol and greatly strengthened, but the low solubility of sorbic acid . We in the actual production process, often encounter situations using potassium sorbate . The author is in accordance with the standards prescribed amount of sorbic acid , potassium sorbate converted into dose , the wine has been filtered sterilization recommended dose of sorbic acid or potassium sorbate are listed according to the different requirements of alcohol under the table , for colleagues to use the reference .
Note that regardless of the number of doses used , sorbic acid bacteria are not resistant effect. Although it can prevent further fermentation of sweet wine , but it can not prevent contamination of wine acetic acid bacteria , lactic acid bacteria can not prevent contamination of wine . When sorbic acid disappears, the risk of bacterial contamination will be doubled , then, the wine has an unpleasant odor , similar to bay leaves greasy , because ethylene glycol has been generated . Sorbic acid in the case of only a certain concentration of ethanol in the presence of sulfur dioxide , in order to exhibit satisfactory results. It can enhance the effect of the latter , but never replace them . The solubility of sorbic acid in water is not very large, it is higher than the soluble form of potassium sorbate . 270g / L solution contains potassium sorbate 200g / L sorbic acid. Due to the low solubility of sorbic acid , when added to the wine must be careful to slowly added , with vigorous stirring , mixed thoroughly using a circulation pump . In the following conditions , sorbic acid can inhibit the activation of yeast in wine :
1 ) According to the wine ‘s alcohol content and acidity using a sufficient amount .
2 ) Wine has to be treated carefully clarified , has done an effective sterilization filter .
3 ) Mixed with wine quickly and completely .
