Effects Of Several Improvement Measures On Chemical Properties Of Soda-alkali Soil

In recent years, with the increasing in population and rapid industrial development, the ecological environment is also deteriorating seriously, the degree of soil salinization is intensified, the salinization of soil degradation has become widespread in the world. It is not only seriously affect the development of modern agriculture and animal husbandry, but also pose a serious threat to natural resources, the biosphere and the ecological environment. With the continuous expansion of saline lands area and the growing demand for food, reasonable development and utilization of saline-alkali land resources, has become an important issue facing humanity, an inevitable requirement of sustainable development of human society.This article outlines the mechanism of the occurrence and development of land salinization and saline-alkali soil at home and abroad improved technology of the status quo, on the distribution of saline-alkali soil in western Jilin Province and the improved use of research progress over the years. By pot and field experiments, respectively, black fungus Waste Material on Sodic Soil chemical properties and underground pipe laying, subsoiling and amendments on soda saline-alkali soil chemical properties. The experimentally derived conclusions are as follows:1) Ck (the absence of any treatment) compared to the different improvement measures under the conditions of the soil organic matter status improved significantly, most of the processing of organic matter content increased. At the same time, a variety of the alkalization indicators has also been significantly improved, pH, decreased exchangeable sodium content, basicity, salt-wide improvement effect. Soil cation exchange capacity also improved.2) The subsoiling not subsoiling:on the basis of different pipe depth of subsoiling for improving the results of the saline-alkali soil is not the same. The results show that soil organic matter content, soil cation exchange capacity in the pipe1.2m on the basis of subsoiling improved better. pH, exchangeable sodium and ESP, the total salt content such as salinity indicators in the buried depth of0.8m on the basis of subsoiling improved to be more obvious.3) Imposed conditioner not impose conditioner:The results of this study show that the imposed conditioner for residential soil organic matter content is higher than the improvers of the district is not imposed, but the usage does not affect the organic matter content. At the same time impose the value of the modifier of cell pH. exchangeable sodium content, basicity, salt and improver of the district imposed compared to both reduce, but improving the results under different pipe depths there are differences. Impose modifier has no effect on soil cation exchange properties.4) The subsoiling pipe and only subsoiling, but not buried contrast:The results show that subsoiling pipe with a single only subsoiling compared to soil CEC value increased, but the decline in organic matter content, pH, total salt content did not change significantly, otherthe alkalization indicator parameters such as exchangeable sodium basicity such as a marked decline.5) The subsoiling pipe, fertilization, and only deep loose, but not buried, no fertilizer compared to:The results show that subsoiling, pipe, fertilizer interaction between the organic matter tends to decrease the trend, the total salt contentinfluence and a single subsoiling not much difference, but for pH, exchangeable sodium, basicity, cation exchange capacity, the improved significantly better than a single deep loose soil.
