Description
The technical field is as follows:
the invention belongs to the field of ecological restoration, and particularly relates to a soil microorganism basic nutrient modifying agent for coastal saline-alkali soil.
Background art:
coastal saline lands are a subset of saline-alkali soils. The salinity of the coastal saline-alkali land is mainly caused by the fact that seawater stays in the sediment forming the plain due to the combined influence of the carrying effect and the dipping effect of rivers and ocean factors such as tides and ocean waves in the process that the offshore rivers carry a large amount of sediment to form the offshore plain. In addition, the formation of coastal saline-alkali soil is dynamically increased, and the coastal saline-alkali soil is continuously silted every year, generally, the closer to the sea area, the more susceptible to the influence of seawater and tides, and the shorter the influence time from the tidal seawater, the higher the salt content of the soil of the coastal beach. Therefore, the salt content of coastal beach soil is generally from seawater, and the salt content of the soil is mainly sodium chloride. In addition, the underground water in the offshore land is influenced by natural factors such as seawater replenishment or seawater invasion, and the underground water level is generally high, the salt content is high, and the mineralization degree is high. The coastal agricultural planting is only suitable for the production of halophytes or salt-tolerant plants under the condition of improving the soil without human intervention. What is more, the coastal saline-alkali land is from coastal areas with developed economic trade and frequent traffic in China, and some coastal towns are used as coastal trade hubs, and the development of the coastal saline-alkali land has extremely important economic and ecological strategic significance. The saline-alkali soil is used as an important reserve land resource and has the greatest development potential in six types of wasteland in China. The development and utilization of coastal saline-alkali land resources have important significance for guaranteeing agricultural production in coastal areas and relieving the tension of land resource utilization in coastal developed areas.
At present, the main measures for improving the saline-alkali soil at home and abroad are hydraulic engineering and physical repair (irrigation and salt washing, drainage and desalting, soil dressing improvement), chemical and agricultural repair (paddy-upland rotation, high polymer soil improvement agent, desulfurized gypsum, fly ash, furfural residue, tailings and the like), biological repair (seed selection, introduction, genetic engineering breeding and the like for breeding saline-alkali tolerant plants and mycorrhizal fungi) and the like aiming at the characteristics of the saline-alkali soil.
