Acid soil conditioning improver

Abstract

The invention relates to an acid soil conditioning improver which can be used as a fertilizer to effectively condition and improve acid soil and ensure good production and high yields of crops as well. The acid soil conditioning improver comprises the following components in percentage by weight: 20-40% of bauxite tailings, 40-60% of a composted organic fertilizer and 20-40% of silicon oxide. A preparation method comprises the following steps: crushing the bauxite tailings till bauxite tailings of 200 meshes account for 80% or greater as a first mother material; mixing the first mother material with silicon oxide as a second mother material; mixing the composted organic fertilizer with the second mother material, and uniformly stirring, thereby obtaining the acid soil conditioning improverof which the pH value is 7.8-8.5. The acid soil conditioning improver is rich in raw material, low in cost, simple in preparation method, easy to produce and prepare, good in use effect, effectivelyapplicable to conditioning and improvement of acid soil, free of environment pollution, capable of ensuring crop growth, achieving high yields of crops and great in economic and social benefit.

Description

technical field [0001] The invention relates to agriculture, in particular to an acidic soil conditioner for agriculture. Background technique [0002] Agriculture is an important industry, and agricultural production is inseparable from fertilizers, including organic fertilizers and inorganic fertilizers. However, due to various reasons, the existing fertilizers are not satisfactory for conditioning and improving acidic soils to ensure high agricultural yields and harvests. [0003] Bauxite tailings are waste resources at the end of the bauxite flotation process. They have a huge stock and source. The main components are primary minerals such as illite, pyrophyllite and montmorillonite, which are rich in iron oxide and potassium oxide. Medium and trace elements such as sodium oxide, calcium oxide, and magnesium oxide are good sources of medium and trace nutrients for plants, but there is no relatively mature resource utilization plan for bauxite tailings slag fertilizer; ...
