Abstract

The invention belongs to the technical field of saline-alkali land treatment, and in particular relates to a special fertilizer for improving a slight saline-alkali land and a preparation method thereof. The improved fertilizer comprises the following components in parts by weight: 30 to 35 parts of flue gas desulfurization gypsum, 10 to 15 parts of citric acid residue, 1 to 5 parts of N-29 methylenebis-urea, 5 to 10 parts of vinegar dregs, 15 to 20 parts of chitosan, 5 to 10 parts of peat, 2 to 3 parts of calcium superphosphate, 0.5 to 1 part of ammonium nitrate, 11 to 14 parts of bentonite, 10 to 15 parts of livestock and fowl manure, 10 to 15 parts of leaf litter, and 1 to 5 parts of bioactivator. The improved fertilizer prepared by the invention is suitable for improvement of the slight saline-alkali land, is fast in desalination, is low in treatment cost, and has an important function on environmental control.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali land treatment, and in particular relates to a special fertilizer for mild saline-alkali land improvement and a preparation 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 and hu...
