Industrial waste can really "save" saline depression – Mosaic texture
Luxi Chemical 2000 tons of industrial waste, agricultural pollution incidents have to stop the local relevant departments, learn from the incident, waste conducive to transform saline depressions. Luxi Chemical waste slag as acidic, while the Xixia pingjipu farm fields southwest of alkaline, just in and. From the perspective of the chemical principle is do the same for, but from the industrial point of view, prove to the local people's lives. Chemical network of the next HC-depth interpretation of your principal contradiction in Chinese reform saline What? From industrial waste may be able to find the principle of where to save the saline depression.
Saline is a salt of a set of product categories, is contained in soil salinity which affect the normal growth of crops, according to incomplete statistics, UNESCO and FAO, the world's area of saline 9.5438 million hectares, of which China is 99.13 million hectares. China alkaline earth and alkali soil formation, the majority of the total carbonate in soil, thus generally higher basicity, severe saline soil area plants almost can not survive. Saline in the use of the process, simply, can be divided into mild saline, saline and alkaline lands moderate. Light saline is its emergence, eighty seven per cent, which the following salt content in the three thousandths; heavy saline is more than six thousandths of its salt content, germination rate of less than 50%; the middle this piece is moderately saline. As science and technology development at present, should not only see the negative side, it should be seen as very valuable land resources, because there are many organisms including plants, including microorganisms that can adapt to this environment, Bingju increasingly more and more researchers are to great enthusiasm into the work of saline treatment, saline treatment will work to achieve the final victory.
Causes
Are a variety of saline-alkali soil under natural conditions in some form, its essence is mainly formed of a variety of soluble salts in the ground for horizontal and vertical re-distribution, so that salinity in the set of salt to the soil surface gradually build up. Affect the formation of saline-alkali soil factors are:
Climatic conditions: in Northeast China, Northwest, North China's arid and semi arid areas, precipitation, high evaporation, the salt dissolves easily in water accumulation in the soil surface. Summer rain and the concentration of the soluble salt with the water seepage to the lower or outflows, this is the "Desalination" season; spring surface water evaporation strong, groundwater salinity with the capillary water rise and gather in the soil surface, which is the main " back to salt "season. Northeast, north, semi-arid areas of sodic obvious "Desalination" "return salt" season, while the Northwest region, due to early precipitation little obvious seasonal variation of soil salinity.
Geographical conditions: high and low slope position on the formation of saline-alkali soil has great influence terrain will directly influence the movement of surface water and groundwater, also with the movement and accumulation of salt is closely related to the terrain view from the large, water-soluble salt with the water from the high Department moves toward low, the accumulation in low-lying areas. Saline-alkali soil mainly in the inland basins, mountain depressions and flat plains of poor drainage areas, such as the Songliao Plain. Small terrain (local area) point of view, the situation in soil salinity of terrain on the contrary, salt is often accumulate in the local office of small convex.
Soil texture and groundwater: soil texture and thickness can affect the movement of capillary water, the speed and height, in general, loamy soil capillary water rising fast, high height, sand and clay, salt accumulation were slower. Ground Water is the key to soil salinity level of water table and groundwater salinity, the size of the high water table, salinity, large, easy to salt accumulation.
The impact of river and sea water: rivers and channels to both sides of the river due to lateral seepage Ershi groundwater elevation, promote salt accumulation. Coastal areas due to sea water immersion, may form a coastal saline soil.
