Abstract

The invention discloses a fertilizer for improving alkaline soil, and a preparation method thereof, and relates to the technical field of soil improvement, wherein the fertilizer comprises the following raw materials by weight: 30-60 parts of calcium phosphate, 10-20 parts of ammonia water, 30-55 parts of humic acid, 15-40 parts of polyacrylate, 20-35 parts of sepiolite powder, 20-30 parts of sesbania, 15-20 parts of sweet clover, 25-35 parts of dry excrement, 35-50 parts of crop straw, 7-10 parts of a microbial bacterial liquid and 10-80 parts of distilled water. According to the invention, the fertilizer for improving alkaline soil is prepared by mixing the natural organic matters and the acidic inorganic fertilizer, so that the content of the available nutrients in soil is remarkably increased, the soil is improved, the ecological improvement is conducted on alkaline soil, the organic matters of soil can be increased, the soil texture structure and the physicochemical properties ofsoil are improved, and the fertilizer has advantages of ecological environmental protection, low cost, convenience and high efficiency; and a large amount of easily degradable components are used, sothat the degradation rate of the fertilizer in soil is increased, the soil micro-ecological environment is improved, and the soil fertility is maintained.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, in particular to a fertilizer for improving alkaline soil and a preparation method thereof. Background technique [0002] Alkaline soil refers to the soil with a pH value greater than 7, that is, the concentration of hydroxide ions in the soil solution is greater than the concentration of hydrogen ions. In practice, it refers to soil with a pH value above 7.3. Generally, it includes calcareous soil, saline soil and alkaline soil. In order to improve the soil structure of alkaline soil and reduce the alkalinity and pH value of alkaline soil, physical improvement, water conservancy improvement and biological improvement are mainly used, which can only temporarily improve alkaline soil and affect the growth and yield of crops. Not much, and although the current chemical improvement can reduce the pH value of the soil, some of them will cause heavy metals and harmful trace elements in the s...
