The river is divided into an outflow river and an inflow river. The area of the river basin of the outflow river injected into the ocean accounts for about 64 percent of the total area of the land in China, the river basin is often influenced by severe (heavy rain and torrential rain) weather, waterlogging disasters often occur, the areas of sandy land in the areas along the river and the lake are continuously enlarged, the soil of the sandy land is not water-retaining and low in fertility, common plants are difficult to grow, and meanwhile the sandy land is one part of important land resources in China; therefore, the problem of soil treatment of sandy soil is to be solved urgently.
The characteristics of sandy land can be mentioned from the microstructure of soil, which is composed of tiny particles, and the particles form a loose and porous system of soil, and are composed of three substances of solid, liquid and gas. The solid matter of the soil comprises two parts of mineral matters and organic matters, the mineral matters look like a framework of the soil, the organic matters look like that the muscles of the organic matters wrap the surface of the mineral matters, and the organic matters are a treasure house for plants to absorb water and nutrients. The liquid part refers to the moisture in the soil, which is kept and moved between the voids of the soil, and is the most active part in the soil, and the gas of the soil refers to the air in the soil, which is filled in those voids that are not occupied by the moisture. The sand has larger gaps, shows better permeability and is an important reason for poor water retention and water storage property. The content of organic matters in sandy soil is low, so that the sandy soil is an important reason for loose soil texture and easy water and fertilizer leakage;
at present, the treatment technology of sandy soil mainly comprises the steps of planting foreign soil, applying organic fertilizer and compound fertilizer to improve the nutrient content of the sandy soil, and changing the pH value of the soil, the contents of nitrogen, phosphorus, potassium, organic matters and humic acid by a specially prepared chemical modifier to improve the physicochemical property of the soil. However, these modifiers have a complicated structure, high investment, few material resources, and limited mass production. The process for improving the sandy soil is long in time, and the comprehensive, systematic, large-area and healthy and durable development can not be realized.
