Embodiment 1

[0053] This embodiment provides a tidal flat saline-alkali dry field soil conditioner. The conditioner is composed of granules and microbial agents, and the granules include blocking agents, acid regulators and organic fertilizers.

[0054] The preparation method includes the following steps:

[0055] (1) Weigh and reserve according to the weight ratio of each component;

[0056] (2) Mix all the blocking agents reserved in step (1), add acid regulator and organic fertilizer after mixing uniformly, mix uniformly and react to form a mixture material, compound and granulate to obtain granules;

[0057] (3) Adding the microbial agent to the granules obtained in step (2) and mixing them evenly to obtain a tidal flat saline-alkali dry field soil conditioner.

Embodiment 2

[0059] This embodiment provides a tidal flat saline-alkali dry field soil conditioner. The conditioner is composed of granules and microbial agents in a weight ratio of 9:5, and the granules include blocking agents, acid regulators and organic fertilizers; The blocking agent includes 20 kg of fly ash and 50 kg of zeolite powder; the acid regulator includes 0.03 kg of zinc sulfate and 0.3 kg of ammonium sulfate; the organic fertilizer includes 24 kg of humic acid and 6 kg of yellow humic acid. The microorganisms contained in the microbial agent include extreme halophilic bacteria, yeast and lactic acid bacteria. The extreme halophilic bacteria is a strain of Aspergillus terreus.

[0060] The preparation method includes the following steps:

[0061] (1) Weigh and reserve according to the weight ratio of each component;

[0062] (2) Mix all the blocking agents reserved in step (1), add acid regulator and organic fertilizer after mixing uniformly, mix uniformly and react to form a mixtu...

Embodiment 3

[0066] This embodiment provides a tidal flat saline-alkali dry field soil conditioner, which is composed of granules and microbial agents in a weight ratio of 1:4, and the granules include blocking agents, acid regulators and organic fertilizers; The blocking agent includes 30 kg of fly ash and 40 kg of zeolite powder; the acid regulator includes 0.05 kg of zinc sulfate and 0.1 kg of ammonium sulfate; the organic fertilizer includes 26 kg of humic acid and 4 kg of yellow humic acid. The microorganisms contained in the microbial agent include extreme halophilic bacteria, yeast and lactic acid bacteria in a weight ratio of 7:2:5.

[0067] The preparation method includes the following steps:

[0068] (1) Weigh and reserve according to the weight ratio of each component;

[0069] (2) Mix all the blocking agents prepared in step (1), mix well, add acid regulator and organic fertilizer while stirring at room temperature 25℃, mix well and react to form a mixture, compound and granulate to ...

Abstract

The invention discloses a soil modifier for dry farmland with saline-alkali soil in mudflat areas and a preparation method of the soil modifier. The modifier is prepared by mixing a granular agent anda microbial agent for a reaction, wherein the granular agent comprises a blocking agent, an acid modifier and organic fertilizer; the blocking agent comprises fly ash and zeolite powder; the acid modifier comprises zinc sulfate and ammonium sulfate. The organic fertilizer comprises humic acid and fulvic acid. After the saline-alkali soil of the dry farmland in the mudflat areas is improved by thesoil modifier for the dry farmland with the saline-alkali soil in the mudflat areas, the original microbial population of the soil is activated, the vitality of the soil is restored, and salt and alkali cannot return to the dry farmland in next 10 years.

Description

Technical field [0001] The invention belongs to the technical field of soil improvement, and specifically relates to a tidal flat saline-alkali land and dry field soil improver and a preparation method thereof. Background technique [0002] my country has a vast area of ​​coastal beaches and abundant water resources. Directly affected by seawater, the saline-alkali soil in this area is widely developed; the saline-alkali soil along the beach reduces the utilization rate of land in coastal areas and restricts the development of agricultural economy. Generally, physical measures are taken to control, mainly the following two methods: one is based on the water and salt operation law of "salt goes with water and salt goes with water", and drainage ditches are actually excavated for low-lying areas, which can lead to The excess water accumulated in the area is discharged to other places, but this method is easy to return to salinity; or, introducing external water into the area, form...
