Description
Technical Field
The invention relates to the technical field of saline-alkali soil improvement, in particular to a saline-alkali soil conditioner and a preparation method thereof.
Background
Saline-alkali soil is a general term for various salinized soil and alkaline soil. Saline-alkali soil is one of the serious ecological environment problems faced by global agriculture nowadays, which causes serious influence on agricultural sustainable development, and how to properly solve the problem of soil salinization is a difficult task. Because the soil body contains a large amount of saline-alkali components and has poor physicochemical properties, the growth of plants is inhibited and even can not grow. Most of soluble salts in the saline-alkali soil are sodium salts, so that the soil is sticky and heavy, the soil colloid is dispersed and emulsified, the air permeability is poor, the soil swells and is muddy when meeting water, the water loss shrinkage is hard, the germination of crop seeds and the normal development of crops are seriously influenced, in addition, the excessive sodium ions in the soil are in alkaline reaction, plant tissues are directly damaged, the root systems of the crops are also easy to rot, the nutrient conversion is influenced, and phosphate fertilizers, trace elements and the like cannot be dissolved and lose efficacy. Therefore, the salinization of the soil has great harm to crops.
The saline-alkali soil improvement is based on the principle of local adjustment and comprehensive improvement, and the saline-alkali soil is actively cultivated and fertilized while salt discharge, salt isolation and salt prevention are carried out, so that the aim of efficiently utilizing the saline-alkali soil is achieved, and at present, the domestic saline-alkali soil control technology mainly comprises the following steps: water conservancy improvement technology, physical improvement technology, chemical improvement technology, biological improvement technology and the like. At present, the measures widely used at home and abroad for treating saline-alkali soil include water conservancy improvement measures (including irrigation, drainage, silt discharge, rice planting, seepage prevention and the like), agricultural improvement measures (including land leveling, improvement and cultivation, soil dressing, fertilization, seeding, crop rotation, intercropping and interplanting and the like), biological improvement measures (including planting salt-tolerant plants and pasture grass, green manure, afforestation and the like) and chemical improvement measures (including applying improvement substances such as gypsum, phosphogypsum, calcium sulfite and the like). Under the action of physical improvement technology, the volume weight of saline-alkali soil is reduced, the porosity and permeability of soil are increased, the water movement of soil is adjusted, and the soil fertility is improved. Chemical modification techniques work by applying chemically modified materials, which mainly include: gypsum, fly ash, citric acid, black alum, phosphogypsum and the like. After the modified material is applied, the physical and chemical properties of the soil are changed, and the acidity is increased. The chemical improvement is to apply some acidic salt substances to improve the property of saline-alkali soil, reduce the pH value of the soil, increase the cation replacement capacity of the soil, reduce the salt content of the soil, enhance the activity of microorganisms and enzymes in the soil and promote the growth of plant roots. Improving the physical property of soil, increasing the granular structure of soil, coordinating the water, fertilizer and gas heat of soil and increasing the fertility of soil. The saline-alkali soil is improved by biological measures in the traditional sense, namely the saline-alkali soil is improved by plants, the method is easy to implement, and the economic benefit is obvious. The biological measures can gradually change the physical characteristics of the soil, so that the soil structure is changed, the texture becomes loose, and the air permeability and water storage capacity are enhanced.
The saline-alkali soil improvement not only relates to effectively reducing the salt content and the pH value of soil, but also relates to the problems of improving the soil structure and reasonably increasing the soil nutrients. The traditional improvement method and the product can not achieve the effect of improving the soil structure while reducing the salt content and the pH value of the soil when improving the saline-alkali soil.
