Problems solved by technology

Soil overacidity leads to soil compaction, heavy texture, soil structure damage, and poor air permeability. After soil acidification, soil biodiversity is changed, the availability of nutrients in the soil is reduced, and cations are lost, making phosphorus, potassium, and calcium , magnesium, molybdenum, boron and other nutrient elements are deficient, resulting in imbalance of soil nutrients and decreased fertility
Moreover, the decrease of soil pH value will activate toxic heavy metal elements and poison crops, resulting in poor growth and development of crops, reduced crop yield and product quality decline, while increasing the potential threat of heavy metal elements to agricultural production and ecological environment
In the prior art, although there are a variety of acidic soil improvers, the improvement effect is poor, and the application amount is relatively large. When applied together with chemical fertilizers, the fertilizer efficiency will be reduced.

Abstract

The invention discloses an acidic soil ameliorant prepared from the following raw materials by weight: 22-38 parts of chicken manure particles, 6-14 parts of hydrated lime powder, 9.8-16.5 parts of calcium lactate, 3.1 to 6.3 parts of light oxidation magnesium powder, 9.2 to 16.3 parts of attapulgite, 2 to 3 parts of plant ash, 2 to 12 parts of chitosan, 1 to 3 parts of shell powder, 1 to 5 partsof seaweed fertilizer and 5 to 10 parts of fiber liquid. The acidic soil ameliorant can effectively neutralize acid hydrogen ions in soil, restore soil fertility at the same time, significantly improve the environment of acid soil, enhance the ability of fertilizer conservation, fertilizer supply and buffer of soil, facilitate the absorption of crops, and has good market prospects and applicationvalue.

Description

technical field [0001] The invention relates to the field of soil improvement, in particular to an acidic soil improver and a preparation method thereof. Background technique [0002] Soil improvement is the process of taking corresponding physical, biological or chemical measures to improve soil properties, soil fertility, crop production, and the soil environment for human survival against the poor texture and structure of the soil. Soil acidification is a manifestation of soil degradation, which refers to a natural phenomenon in which soil acidification increases and becomes strongly acidic or extremely acidic. Low soil pH will affect the physical and chemical properties of the soil, thus indirectly affecting the growth and development of plants. Soil overacidity leads to soil compaction, heavy texture, soil structure damage, and poor air permeability. After soil acidification, soil biodiversity is changed, the availability of nutrients in the soil is reduced, and cation...
