Acid soil conditioner and application method thereof

Abstract

The invention belongs to the technical field of soil conditioning, and particularly relates to an acid soil conditioner and an application method thereof, and the acid soil conditioner comprises the following components in parts by weight: 30-50 parts of an acid regulating agent, 20-25 parts of a mineral source conditioner, 10-12 parts of alginic acid, 5-8 parts of organic carbon, 10-15 parts of silicon dioxide and 5-10 parts of a microbial preparation. Through cooperative use of the composite acid regulating agent, the mineral source conditioner, the microbial preparation, alginic acid, organic carbon and silicon dioxide, the pH value of soil can be rapidly increased, the stability, air permeability and water permeability of a soil structure are improved, the biological activity of the soil is increased, release of available nutrients is promoted, the antibacterial activity and stress resistance of crops are improved, and the yield of the crops is increased. And the fertilizer has relatively strong nitrogen-fixing, phosphorus-fixing and potassium-dissolving functions, effectively enhances the photosynthesis of plants, promotes the reproduction of soil microorganisms, and can greatly improve the crop yield.

Description

technical field [0001] The invention relates to the technical field of soil conditioning, in particular to an acidic soil conditioner and an application method thereof. Background technique [0002] Acidic soil refers to the soil with a pH<7 that lacks alkali metals and alkaline earth metals and absorbs a large amount of H+. The sources of acidity include: carbonic acid in rainwater, metabolites of microorganisms and plant roots, organic acids produced during the decomposition of organic matter, and ferrous sulfide. Once the sulfuric acid generated by oxidation and the decomposition of chemical fertilizers form an acidic environment, the alkaline metal ions adsorbed on the clay and humus will be replaced by H+, causing the lack of these metal ions in the soil, so the soil is acidic. [0003] Acidic soil conditioner has a significant effect on balancing the pH of the soil, especially to solve the acidification of the soil caused by long-term use of acidic fertilizers, whic...

Problems solved by technology

[0006] Aiming at the deficiencies in the prior art, the present invention provides an acidic soil conditioner and its application method, which solves the problem that although the existing acidic soil conditioner has a certain soil pH conditioning effect, its function is relatively single, and the soil acidity correction speed Slow, poor soil remediation effect and nitrogen fixation, phosphorus fixation and potassium solution effect, low yield increase, and poor overall performance
