Abstract

The invention belongs to the technical field of soil conditioning, and specifically relates to an acid soil conditioner. The acid soil conditioner comprises the following raw materials in parts by weight: 50-75 parts of dealumination red mud powder, 15-30 parts of phosphogypsum, 5-10 parts of plant ash, 5-10 parts of a calcium magnesium phosphate fertilizer, 0.5-1 part of a compound microbial agent and 10-25 parts of a cementing material. The acid soil conditioner provided by the invention has the advantages that acid soil can be conditioned in a targeted manner, in particular, a defect that nutrient elements cannot be fixed and retained in the acid soil due to eluviation can be eliminated, aluminium elements in the acid soil can be effectively fixed, and influences of aluminum toxicity onthe soil can be avoided; and meanwhile, sorely lacked potassium, magnesium and calcium in the soil are supplemented, hydrogen and aluminium are adsorbed and cured, the acidic degree of the soil is effectively reduced, soil microcirculation is reconstructed, and yield increasing and income increasing of crops are guaranteed.

Description

technical field The invention belongs to the technical field of soil improvement, and in particular relates to an acidic soil improver. Background technique The normal growth and development of plants depends on a good soil environment, but in nature, there are often various obstacles in the soil where plants grow, which limit the growth of plants. For example, there are high concentrations of salt in large areas of saline-alkali soils on the world's land surface; high concentrations of H in acidic soils + , Al 3+ , Mn 2+ and Fe 2+ etc.; excess reducing substances and Fe in flooded soil 2+ etc.; lack of sufficient available phosphorus, iron and zinc in calcareous soil. These soils with obstacles to plant growth are called adversity soils. The adversity soil is widely distributed and difficult to improve. Therefore, it has become a limiting factor for the development of agricultural production. Acidic soil is a general term for soils with low pH value, including red s...
