Problems solved by technology

However, these three improvers do not contain microbial agents, ignoring the problem of stubborn anti-salinity in tidal flat saline-alkali land, which is not conducive to the establishment of a long-term mechanism, and continuous addition of improvers is required to maintain orderly development of saline-alkali soil

Abstract

The invention discloses a mudflat saline and alkaline land paddy field soil improvement agent and a preparing method thereof. The improvement agent is formed by mixing a granular agent and a microbialagent and carrying out a reaction between the granular agent and the microbial agent, wherein the granular agent comprises a blocking agent, an acidity adjusting agent and an organic fertilizer. Through the preferable blocking agent and a settling agent, the soil improvement agent spontaneously conducts water and soil separation and natural settling in a saline and alkaline land plowing layer, and finally, an inertia saline and alkaline isolation interface is formed at a plow pan; the blocking agent aggregates soil salt, so that the soil salt is prevented from being aggregated on the surfacelayer. After mudflat paddy field saline and alkaline land is improved through the mudflat paddy field saline and alkaline land improvement agent, original microbiota of the soil is activated, and thevitality of the soil is recovered.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a mud flat saline-alkali land paddy field soil improver and a preparation method thereof. Background technique [0002] my country has a vast area of ​​coastal tidal flats and abundant water resources. Affected directly by seawater, saline-alkali soils are widely developed in this area; saline-alkali soils in coastal tidal flats reduce the utilization rate of land in coastal areas and restrict the development of agricultural economy. Generally, physical measures are taken for treatment, mainly in the following two ways: one is based on the water-salt operation law of "salt comes with water, salt goes with water", digging drainage ditches for low-lying areas can lead out the Excess water accumulated in the area is discharged to other places, but this method is prone to salinization; or, the introduction of external water to the area forms an aquifer at a cert...
