Description
Technical Field
The invention relates to the technical field of environmental engineering, in particular to an organic mineral mixture and a method for improving saline-alkali soil and raising seedlings by using the same, and further relates to a method for recovering and improving the saline-alkali soil by combining biotechnology and chemical treatment technology.
Background
Along with the deterioration of ecological environment, saline-alkali soil tends to be expanded year by year, and a large amount of saline-alkali soil is widely distributed in different areas. Saline-alkali soil is mainly formed because the pH value of the soil is obviously higher than that of the neutral soil, wherein the pH value of the light saline-alkali soil is between 7 and 8, the pH value of the medium saline-alkali soil is between 8 and 9, and the pH value of the heavy saline-alkali soil exceeds 9. The higher pH in saline-alkali soil generally requires neutralization by application of acidic organic fertilizer to lower the pH. In addition, the high salt content (0.6% to 1.0%) in saline-alkali soil and the high proportion of exchangeable sodium ions (Na +) present a serious threat to plant growth, these sodium ions being mainly present in the form of compounds such as NaHCO 3、Na2CO3, naCl, etc.
One of the characteristics of saline-alkali soil is that salt migrates with the flow of moisture, i.e. "salt comes with water, salt goes with water". For example, saline-alkali soil in a certain region has a pH of 8, an organic matter content of only 0.62%, a total soluble salt content of 0.41, and a serious lack of organic matter in soil. And due to accumulation of salt, osmotic pressure of soil can be increased, so that plant root systems are difficult to absorb water. In addition, saline-alkali soil can inhibit plant growth, destroy nutrient balance, lead to root rot and inhibit normal growth of root systems.
In the aspect of improving saline-alkali soil, a fresh water drainage and irrigation technology or a physical improvement technology is generally adopted, wherein the fresh water drainage and irrigation technology is used for dissolving and removing salt and alkali in soil by utilizing fresh water irrigation, and meanwhile, drainage ditches are dug among crop rows to ensure that the groundwater level cannot rise, however, the key point of the method is that water resources are reasonably managed, and the groundwater level is prevented from rising; the physical improvement technology improves the physical property of soil by using a physical modifier, reduces the evaporation of water and prevents the return of salt, however, the method faces the problems of lack of fresh water resources, higher pH value of soil, high groundwater level, movement of saline alkali along with the water and the like. The problems of saline-alkali soil can be relieved in a short period by utilizing methods such as fresh water irrigation and drainage, soil turning and salt burning, planting saline-alkali tolerant plants and the like, however, the problems of saline-alkali soil cannot be fundamentally solved due to the fact that the saline-alkali soil is barren, lacks organic matters and is easy to harden.
