Abstract

The invention relates to a corn field acid soil improving fertilizer. The corn field acid soil improving fertilizer consists of an inner layer and an outer layer, wherein the inner layer is prepared from the following components in parts by weight: 5 to 15 parts of urease, 10 to 15 parts of cellulase, 10 to 15 parts of lactic acid bacteria agent and 10 to 15 parts of silicate bacterial agent; the outer layer is prepared from the following components in parts by weight: 20 to 30 parts of astragalus sinicus powder, 10 to 15 parts of quick lime, 15 to 25 parts of polyacrylamide, 5 to 15 parts of oyster shell powder, 1 to 10 parts of humic acid, 1 to 15 parts of palm oil, 1 to 5 parts of potassium polyphosphates, 10 to 20 parts of bone powder, 10 to 20 parts of phosphorite powder, 20 to 30 parts of bentonite, and 1 to 5 parts of trace elements. By adopting the corn field acid improving fertilizer, nutrients of soil are increased, and the water retention performance of land is improved.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a fertilizer for improving acidic soil of corn fields; the invention also relates to a preparation method of the fertilizer for improving acidic soil of corn fields. Background technique [0002] Acidic soil is a general term for soil with a pH value less than 7. The normal growth and development of plants depends on a good soil environment. However, in nature, there are often various obstacles in the soil where plants grow, which limit plant growth. On acidic soil A serious problem is low nutrient availability, and there are many types of nutrients involved. For example, acidic soils are generally deficient in nitrogen, phosphorus and potassium; many soils are deficient in calcium and magnesium; some soils are deficient in molybdenum. It is determined by the characteristics of acidic soil composition and climate characteristics. In acidic soil, iron and aluminum are highly active, and form insol...
