Embodiment 1

[0021] (1) Irradiate attapulgite (colloidal grade, 260 mesh) dry powder under gamma rays (2MeV, 30kGy) for 5 minutes to disperse attapulgite to enhance its nutrient retention;

[0022] (2) By weight, 6 parts of weathered coal (20% humic acid content) and 1 part of sodium acrylate are evenly mixed, and then added to water to make a suspension with a concentration of 50g / L. Under stirring for 20 minutes, the sodium acrylate was graft-copolymerized on the weathered coal surface. Then dry at 50 degrees Celsius and pulverize to 260 mesh to obtain weathered coal-sodium polyacrylate composite;

[0023] (3) Crush the lime to 260 mesh;

[0024] (4) Crush the carbon residue to 260 mesh;

[0025] (5) The trace element compound is mixed by 6 parts of ammonium molybdate, 16 parts of borax, and 20 parts of zinc sulfate by weight, and the fineness of the trace element compound is 260 mesh;

[0026] (6) By weight, 2 parts of attapulgite obtained in (1), 4 parts of weathered coal-sodium pol...

Embodiment 2

[0030] (1) Irradiate the dry powder of attapulgite (colloidal grade, 280 mesh) under gamma rays (3MeV, 35kGy) for 10 minutes to disperse the attapulgite to enhance its nutrient retention;

[0031] (2) By weight, uniformly mix 9 parts of weathered coal (30% humic acid content) with 2 parts of sodium acrylate, and then add it into water to make a suspension with a concentration of 80g / L. Under stirring for 30 minutes, the sodium acrylate was graft-copolymerized on the weathered coal surface. Then dry at 60 degrees Celsius and pulverize to 280 mesh to obtain weathered coal-sodium polyacrylate composite;

[0032] (3) Crush the lime to 280 mesh;

[0033] (4) Crush the carbon residue to 280 mesh;

[0034] (5) The trace element compound is mixed by weight from 7 parts of ammonium molybdate, 17 parts of borax, and 25 parts of zinc sulfate, and the fineness of the trace element compound is 280 mesh;

[0035] (6) By weight, 3 parts of attapulgite obtained in (1), 3 parts of weathered...

Embodiment 3

[0039] (1) Irradiate the dry powder of attapulgite (colloidal grade, 300 mesh) under gamma rays (4MeV, 40kGy) for 20 minutes to disperse the attapulgite to enhance its nutrient retention;

[0040] (2) By weight, uniformly mix 12 parts of weathered coal (with a humic acid content of 45%) and 3 parts of sodium acrylate, and then add it to water to form a suspension with a concentration of 100g / L. Under stirring for 40 minutes, the sodium acrylate was graft-copolymerized on the weathered coal surface. Afterwards, dry at 70 degrees Celsius and pulverize to 300 mesh to obtain weathered coal-sodium polyacrylate composite;

Abstract

The invention provides an improvement agent for improving soybean saline and alkaline land soil. The improvement agent is prepared by mixing the following components in parts by weight: 2-3 parts of attapulgite, 3-4 parts of a weathered coal-sodium polyacrylate compound, 1-2 parts of lime, 1-2 parts of carbon residues and 1-2 parts of a micro element compound. Materials such as attapulgite and sodium acrylate are modified, grafted and polymerized to achieve the effects of water retention, fertilizer maintenance, salt reduction, alkali decreasing, soil loosening and the like so as to ensure that the saline and alkaline land soil for planting soybeans can be improved and a saline and alkaline land improvement fertilizer can be prepared by adding the materials into a fertilizer. Compared with the prior art, a method provided by the invention has the advantages of low cost, rich raw materials, environmental friendliness, high efficiency and the like.

Description

technical field [0001] The invention relates to a soil functional improver and improved fertilizer for improving soybean saline-alkali land. Background technique [0002] Soil salinization has always been the main obstacle restricting the development of my country's agriculture and the improvement of comprehensive capabilities. If the control and prevention efforts are not strengthened, it will directly affect my country's agricultural production capacity and food security. The deterioration of the ecological environment caused by salinization, It will also affect the living and development space of the people in the irrigation area. Therefore, the prevention and development of saline-alkali land is an issue that cannot be ignored in the agricultural development of the irrigation area. It plays an important role in promoting the sustainable development of agriculture and ensuring food security. [0003] Soybean, as a typical crop representative in northern my country, is an ...
