Problems solved by technology

Some improved plants have large biomass and good salt tolerance. The aboveground part can remove a lot of salt after harvesting. Through biological improvement measures, the coverage of the soil surface can be increased, and the soil microclimate can be adjusted, thereby reducing water evaporation and inhibiting salt. At the same time, the growth of plant roots improves the soil structure and improves the effect of salt leaching. After the aboveground biomass returns to the soil, it can increase organic matter, improve soil structure and soil fertility, but biological improvement also has its limitations. Each plant It has its own range of salt tolerance, so in the process of introducing and planting salt-tolerant plants, it is necessary to select suitable plant varieties to create suitable soil water and salt conditions for the restoration of plant growth

Abstract

The invention discloses a construction method of a plant community for saline-alkali land improvement. The method includes the step: planting plants comprising arbors, shrubs and herbaceous plants according to a configuration mode. The arbors are birch-leaf pears, the shrubs are sophora viciifolia and ligustrum vicaryi, and the herbaceous plants are lance coreopsis, Indian rorippa herbs and eschscholzia californica. According to the plant community for saline-alkali land improvement constructed by the construction method, the plants are reasonably matched, the general porosity, water content,a soil pH (potential of hydrogen) value and soil salinity of a saline-alkali land soil sample can be effectively improved, and the content of Na<+> and Ca<2+> in the soil is reduced.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land management, in particular to a method for constructing plant communities for saline-alkali land improvement. Background technique [0002] Saline-alkali soil is a general term for various types of saline soil, alkaline soil, and different degrees of salinized and alkaline soil. Because the soil contains a large amount of saline-alkali components and has bad physical and chemical properties, the growth of plants is inhibited or even unable to grow. Saline-alkali soil is widely distributed in my country, and the northwest, north, northeast and coastal areas are the main distribution areas of saline-alkali soil in my country. Affected by regional climate, topography, parent material, hydrogeological and biological factors, saline-alkali soil has various types and has obvious characteristics. Seasonality, strong surface aggregation, high heterogeneity, complexity of types, and repetition of...
