Embodiment 1

[0035] The secondary saline-alkali soil conditioner for the Yellow River irrigation area is composed of the following raw materials in parts by weight:

[0036] 5 parts of fluorocarbon modified polyacrylamide;

[0037] 18 parts of desulfurization waste;

[0038] 55 parts of mixed grass powder, said mixed grass powder is made up of quinoa quinoa, prairie wormwood, old awn wheat, star grass, chingrass, and quinoa chinense;

[0039] 10 parts of composite microorganisms, the composite microorganisms are composed of Pseudomonas, Flavobacterium oryzae, Bacillus subtilis, Bacillus licheniformis, Trichoderma pseudoconii;

[0040] 28 parts organic fertilizer;

[0041] 25 parts diatomaceous earth.

[0042] Among them, N-propyl, N-hydroxyethyl perfluorooctane sulfonamide is reacted with acrylic acid to obtain N-propyl, N-hydroxyethyl perfluorooctane sulfonamide acrylate, and then copolymerized with acrylamide to obtain fluorine Carbon modified polyacrylamide.

Abstract

The invention relates to saline-alkali land soil improvement technologies, and especially relates to a Yellow River irrigation area secondary salinization land conditioner, a preparation method and application thereof. According to the invention, fluorocarbon modified polyacrylamide, desulfurization waste, mixed grass powder, a compound microorganism, an organic matter fertilizer and diatomite are mixed. The Yellow River irrigation area secondary salinization land conditioner is blended into farm manure for composting, and then the mixed manure can be applied into soil so as to effectively improve the soil structure, increase the soil moisture content, and effectively preventing soil nutrient loss.

Description

technical field [0001] The invention relates to saline-alkali soil improvement technology, in particular to a secondary saline-alkali soil conditioner for the Yellow River irrigation area, a preparation method and application thereof. Background technique [0002] Salinized soil is distributed in the arid, semi-arid and semi-humid Northwest, North China provinces and parts of Northeast China. According to the second national soil census data, the area of ​​saline-alkali land in my country is 3460hm 2 . Saline-alkali soil refers to the general designation of the soil where the accumulation of water-soluble salts (such as sodium chloride, sodium carbonate, etc.) that are harmful to crop growth exceeds a certain limit, which is harmful to the normal growth of crops. Two conditions must be met for the formation of saline-alkali land, one is arid climate and high groundwater level; the other is low-lying terrain with no drainage outlet. Groundwater contains a certain amount of...
