Abstract

The invention belongs to the technical field of saline-alkali soil improvement and particularly relates to an improving agent and improving method for strongly saline-alkali soil quick fertilization. The improving agent is prepared from, by weight, 55-60 parts of flue gas desulfurization gypsum, 20-30 parts of magnetized fly ash, 30-40 parts of cellulose-acrylamide, 11-16 parts of humic acid, 5-9 parts of polyhydroxy phosphate ester, 20-25 parts of chitosan, 5-10 parts of calcium nitrate, 1-5 parts of N-29 methylenebis, 5-10 parts of pumice stone powder, 1-5 parts of magnesium sulfate, 1-3 parts of aluminum sulfate, 0.5-1 part of ferrous sulfate, 1-5 parts of stainless steel slag, 10-15 parts of poultry and livestock manure and 1-2 parts of biological bacterial fertilizer. The prepared improving agent is suitable for improvement of strongly saline-alkali soil, desalination is quick, improvement cost is low, and the use effect is remarkable.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali land treatment, and in particular relates to an improver for rapid fertilization of severe saline-alkali land and an improvement method thereof. Background technique [0002] Saline-alkali soil is a general term for saline soil, alkaline soil and various salinized and alkalized soils. Saline soil refers to the soil in which the soluble salt content in the soil reaches a certain level, which can cause obvious harm to the growth and development of plants. Alkaline soil refers to the soil that contains a large amount of exchangeable ions in the soil, and the amount reaches the level that can harm the growth and development of plants and change the soil properties. Soil salinization refers to the process in which the soil type gradually changes to saline-alkali soil due to the accumulation of a large amount of saline-alkali ions in the soil, and its influencing factors include natural factors a...
