Organic fertilizer for improving acidic soil and preparation method thereof

Abstract

The invention discloses an organic fertilizer for improving acidic soil and a preparation method thereof. The organic fertilizer for improving the acidic soil is prepared from the following raw materials in parts by mass: 90-100 parts of stonewort, 20-30 parts of sphagnum, 40-50 parts of excrements of livestock, 10-20 parts of sawdust, 10-15 parts of plant ash, 10-15 parts of crop straws and 1-5 parts of a microbial inoculants. The organic fertilizer for improving the acidic soil can greatly improve the soil and can reduce the acidity of soil; organic substances such as animal manure are matched to provide nutrients needed by crops, so that the fertility level of the soil is improved, and the activity of soil microorganisms further can be increased, and therefore, the organic fertilizer is beneficial for plant growth.

Description

technical field [0001] The invention relates to the technical field of fertilizer production, in particular to an acid soil-improving organic fertilizer using charophytes as a main ingredient and a preparation method thereof. Background technique [0002] Soil acidification is a common natural process in the process of soil formation and development. Acidic soil mainly exists in rainy temperate regions, tropical and subtropical regions. Soil acidification will cause many hazards. For example, after soil acidification, the weathering of aluminum-containing primary and secondary minerals in the soil accelerates and releases a large amount of aluminum ions, forming aluminum compounds that can be absorbed by plants. Excessive aluminum absorbed by plants will be reduced to plant products. Quality; soil acidification will also reduce cation exchange capacity and base saturation, and the loss of soil mineral nutrients will be serious; soil acidification will also enhance the fixati...

Soil acidification will cause many hazards. For example, after soil acidification, the weathering of aluminum-containing primary and secondary minerals in the soil accelerates and releases a large amount of aluminum ions, forming aluminum compounds that can be absorbed by plants. Excessive aluminum absorbed by plants will be reduced to plant products. Quality; soil acidification will also reduce cation exchange capacity and base saturation, and the loss of soil mineral nutrients will be serious; soil acidification will also enhance the fixation of phosphate and molybdate in soil, and reduce the availability of soil phosphorus and molybdenum. Lead to soil barrenness, affecting the growth and development of plants; soil acidification will also cause the activation of toxic heavy metals, affecting human health through the food chain; soil acidification will affect the activities of microorganisms, thereby affecting the decomposition of soil organic matter and the C, N, P, S cycle
