Embodiment 1

[0031] Soil improvement effect of special fertilizer for saline-alkali land greening in Daganggang West Street, Binhai New Area, Tianjin

[0032] Special fertilizer formula for greening saline-alkali land: 30% commercial organic fertilizer, 15% calcium-increasing liquid slag, 20% weathered coal, 15% biological fermentation residue, 10% desulfurized gypsum, 3% urea, 6% diammonium phosphate, and 1% zinc sulfate. The percentages are mass percentages. Among them, commercial organic fertilizers should choose commercial organic fertilizers with a mass percentage of organic matter ≥ 30%, a moisture content of ≤ 30%, and a pH ≤ 9. For weathered coal, a mass percentage of humic acid ≥ 20% and a moisture content of ≤ 30% weathered coal.

[0033] Preparation method: dry the biological fermentation residue (with a water content of 25%), crush it through a 2mm sieve, and mix it evenly with the weathered coal crushed through a 2mm sieve to obtain mixture 1; grind the calcium-increased liqu...

[0037] Example 2: Effect of special fertilizer for greening saline-alkali land in Huanghua City, Hebei Province to improve soil

[0038] Special fertilizer formula for greening saline-alkali land: 35% decomposed cow dung, 20% calcium-increasing liquid slag, 15% weathered coal, 10% biological fermentation residue, 10% desulfurized gypsum, 3% urea, 6% diammonium phosphate, and 1% zinc sulfate. The percentages are mass percentages. Among them, decomposed cow dung is selected from decomposed cow dung with a mass percentage of organic matter ≥ 30%, a moisture content of ≤ 30% and a pH ≤ 9, and a weathered coal with a mass percentage of humic acid ≥ 20% and a moisture content of ≤ 30% weathered coal.

[0039] Preparation method: dry the biological fermentation residue (with a water content of 25%), crush it through a 2mm sieve, and mix it evenly with the weathered coal crushed through a 2mm sieve to obtain mixture 1; grind the calcium-increased liquid slag for 5 minutes and pass it...

Abstract

The invention relates to a fertilizer special for saline-alkali land greening, a preparation and application method thereof. The fertilizer special for saline-alkali land greening comprises the following components by mass percentage: 20%-40% of an organic material, 15%-30% of calcium enriched liquid slag, 10%-20% of a humic acid material, 10%-20% of biological fermentation residue, 10%-20% of desulfurized gypsum, 3%-6% of a nitrogen fertilizer, 3%-6% of a phosphate fertilizer, and 0.5%-2% of zinc sulfate. The fertilizer special for saline-alkali land greening provided by the invention generally takes industrial and agricultural waste as the main raw materials, improves light and medium saline-alkali soil through physical, chemical and biological effects, effectively enhances the content of soil organic matters and nutrients, improves soil structure, increases soil aeration and water permeation capacity, prevents soil alkalization, and promotes the root growth of garden plants.

Description

technical field [0001] The invention relates to the technical field of soil fertilizers, in particular to a special fertilizer for saline-alkali land greening and its preparation and application methods. Background technique [0002] Saline-alkali land is an important type of land resources. According to statistics, the area of ​​saline-alkali land in the world is about 954 million hm 2 , the area of ​​saline-alkali land in my country is about 99.133 million hm 2 . Rational development and utilization of saline-alkali land resources is of great significance to protecting and improving the ecological environment and ensuring the sustainable development of human society. Saline-alkali soil contains more saline-alkali components, which are toxic to plants; saline-alkali soil structure is usually poor, with weak air and water permeability, which is not conducive to the growth of plant roots; saline-alkali soil has a low degree of natural maturation and poor fertility, which ca...
