Abstract

The invention relates to a fertilizer for saline-alkali soil. The fertilizer is prepared from the following raw materials in parts by weight: 5-20 parts of humic acid, 0.3-1 part of microorganisms, 6-16 parts of farmyard manure, 15-40 parts of straws, totally 5-10 parts of calcium superphosphate, ferrous sulfate, coal ash, furfural residues and flue gas desulfurization gypsum, 6-14 parts of a nitrogen fertilizer, 2-4 parts of a phosphatic fertilizer and 2-3 parts of a potassic fertilizer. The invention further relates to a preparation method of the fertilizer for saline-alkali soil. The fertilizer for saline-alkali soil, which is provided by the invention, has the beneficial effects that the fertilizer for saline-alkali soil has the characteristics of being low in cost and simple in preparation method, can be used for effectively improving the condition of saline-alkali soil, reducing the content of salt of soil and the pH value and increasing the content of organic matters in soil, and is particularly suitable for being applied to the saline-alkali soil.

Description

technical field [0001] The invention relates to the technical field of agricultural chemical fertilizers, in particular to a fertilizer for saline-alkali soil and a preparation method thereof. Background technique [0002] Saline-alkali soils are lands where the soil contains excess soluble salts. Saline-alkali soil is a general term for saline soil, alkaline soil, and different degrees of salinized and alkalized soil. Among them, saline soil mainly refers to salinized soil with high chloride or sulfate content. The soil is alkaline, but the pH value is not necessarily high. Alkaline soil refers to the soil containing carbonate or heavy phosphate, the pH value is high, the soil is alkaline, the organic matter content of saline-alkali soil is small, the soil fertility is low, the physical and chemical properties are poor, and there are many anions and cations harmful to crops. Promote seedlings. [0003] my country's saline-alkali land is mainly distributed in the northeas...
