Acid soil conditioner

Abstract

The invention belongs to the field of agricultural planting, and particularly relates to an acid soil conditioner which comprises biochar, enzymes, molasses and protein raw materials. The biochar enzyme is prepared from, by weight, 85-92% of biochar, 1-2% of enzymes, 0.2-0.5% of molasses and 6-9% of protein raw materials. The preparation method comprises the following steps: uniformly mixing the biochar, the rice bran or the wheat bran, spraying the enzyme and the molasses by using a spraying method, stirring while spraying until the materials are uniformly mixed, and fermenting; the fermentation process comprises the step of fermenting for 1525 days under the conditions that the temperature is kept at 6070 DEG C and the humidity is kept at 6065%. The organic matter content of soil can beincreased; the soil microorganism growth is promoted; the microorganism total quantity is enriched; the pH of the acid soil can be effectively improved, and the pH value of the soil is adjusted; the activity of protease and urease in the soil is improved, so that the activity of the soil is enhanced, and the soil fertility is improved.

Description

technical field [0001] The invention belongs to the field of agricultural planting, and in particular relates to an acidic soil improver. Background technique [0002] Acidic soils include brick red soil protein raw materials, red soil, red soil, yellow soil, podzolite and dry red soil. The weathering and leaching effects of acidic soil are relatively strong, the iron and aluminum oxides are obviously enriched, the biomass cycle is very rapid, the soil base saturation is low, and the pH is generally in the range of 4.5 to 6.0. Not only the soil acidity is high , and low fertility levels. Soil layered aluminosilicate minerals, aluminum-containing oxides and hydroxides contain a large amount of aluminum, and soil acidification accelerates the weathering of aluminum-containing minerals in the soil and releases a large amount of aluminum ions. The concentration of soluble aluminum in the soil increases, and the toxicity of aluminum to plants increases, resulting in crop yield ...
