Description
Technical Field
The invention relates to a saline-alkali soil improvement method.
Background
The distribution area of the western soda saline-alkali soil in the Songnen plain is about 373 maha, and the soil is expressed as 'three high and two low' (namely high pH, high soda content, high exchangeable sodium content, low permeability and low nutrient availability). The large-area severe soda saline-alkali soil and the alkaline spot land are idle and abandoned due to the difficulty in development and utilization by conventional means or high development and utilization cost, so that the great waste of land resources is caused. In recent years, the development and utilization of soda saline-alkali soil of the soil-planting rice are improved by physical, chemical and biological means.
Chemical modification is one of the major routes to severe soda alkali, which was difficult to utilize under past production conditions. The chemical modifiers reported at present mainly comprise calcium chloride, gypsum, phosphogypsum, flue gas desulfurization gypsum, sulfuric acid, hydrochloric acid, sulfur, pyrite, aluminum sulfate and the like. The main practical production applications are gypsum modifiers such as gypsum, phosphogypsum, flue gas desulfurization gypsum and the like, and the improvement principle is that Ca in the gypsum modifiers is used2+And Mg2+Displacing Na adsorbed by soil particles+The recommended gypsum application amount for the severe soda saline-alkali soil improvement is 30 t/ha.
The key of the utilization of the soda saline-alkali soil for improving soil is to wash salt with water, inhibit the salt with water and establish a ground surface desalting layer. Due to Na+The soil grain surface adsorbability is strong, the simple field soaking-drainage process is poor in salt washing effect, multiple field soaking salt washing is required before rice transplanting and land preparation, water resource waste is large, the utilization of paddy fields of severe soda-soda lands is realized, the conventional utilization mode is to carry out chemical improvement firstly, and generally, an improver needs to be put in soil to be matched with irrigation drainage, salt washing and salt removal, the soil agglomeration process is promoted, and the soil permeability is enhanced. The soil structure is improved, the salt leaching speed is accelerated, the desalting layer is accelerated, the salt leaching effect is improved, and the severe saline-alkali soil improvement needs to be drained for 3-5 times.
The obtained research results have great significance for the development and utilization of severe soda saline-alkali soil, however, the current soil improvement-rice planting development and utilization mode still has some defects: (1) a large amount of modifying agents are required to be added for soil modification, so that the initial land development cost is too high, common farmers are difficult to bear, and finally a large amount of land is abandoned for tillage. (2) In a certain period after the modifier is applied, the saline-alkali content in water is greatly improved due to ion replacement, and the green turning and growth of rice seedlings are damaged, so that frequent field soaking and drainage, even water inflow and drainage are needed, and the great waste of water resources and soil nutrients is caused. (3) The long reaction time is needed for the establishment of the "lightening layer" after the modifier is applied, the yield and the income of the rice are low in the period, and the production enthusiasm of farmers is poor.
