Acidic soil adjusting fertilizer

Abstract

The invention provides an acidic soil adjusting fertilizer. The acidic soil adjusting fertilizer is prepared from the following components by weight: 45 to 55 parts of plant ash, 10 to 25 parts of calcium powder, 8 to 12 parts of humic acid, 8 to 12 parts of modified plant straw, 4 to 6 parts of organic soil, 4 to 6 parts of bamboo charcoal, 2 to 4 parts of sawdust, 1 to 3 parts of olive residue, 2 to 4 parts of sea mud, 2 to 4 parts of calcium superphosphate, 1 to 3 parts of borax, 0.4 to 0.6 part of alpha-isolupanine, 1 to 3 parts of urea, 0.4 to 1 part of compound sodium nitrophenolate, 1 to 2 parts of tea residue, 1 to 2 parts of potassium fulvate, 0.4 to 1 part of shell powder, 1 to 2 parts of meerschaum powder, 1 to 2 parts of potassium chloride, 1 to 3 parts of modified corn starch, 0.4 to 1 part of pinecone, 1 to 2 parts of chelated magnesium, 1 to 2 parts of garlic extract and 1 to 2 parts of chinaberry extract. The acidic soil adjusting fertilizer can retain fertilizer and water and realize sustained release and controlled release, is slightly alkaline, has high biotic potassium content, is a superexcellent acidic soil amendment since common soil is slightly acidic and lacks potassium, eliminates a pollution source of a biomass power plant and better protects the ecological environment.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to an acidic soil regulating fertilizer. Background technique [0002] Soil acidification is a natural process in the process of soil formation. In my country, it is generally distributed in tropical and subtropical regions. The soil is red or yellow. Although the colors are different, the two are similar in occurrence and production and utilization. They are collectively classified under the red soil series or Aluminized soil class, the pH of most soils is less than 5.5, a large part of which is less than 5.0, even as low as 4.5 (Liu Chengjun, 2007). The low pH value and high aluminum content of acidified soil are the limiting factors for crop yield. [0003] There are two measures to reduce soil acidification: one is to use alkaline substances as amendments, such as lime, organic fertilizer, zeolite, fly ash, silicon fertilizer, etc., to reduce the acidity of the soil, impro...

Problems solved by technology

Its manifestations are as follows: one is that the soil is compacted, which deteriorates the soil quality; the other is that the effective nutrients are excessively calcified and cannot be absorbed by the crops, resulting in waste of nutrients; the third is that the aggregate structure of the soil is destroyed, so this method should not be promoted (Wang Renshan, 2006)
