Abstract

The invention discloses an organic improving agent for acid soil. The organic improving agent for the acid soil comprises the following components in parts by weight: 300 to 350 parts of organic ecological fertilizer, 200 to 220 parts of modified biochar, 5 to 8 parts of active oligopeptide, 15 to 18 parts of diammonium hydrogen phosphate, 4 to 5 parts of zinc sulphate, 1.5 to 2 parts of ammonium molybdate, 30 to 33 parts of a water retaining agent, 100 to 120 parts of an auxiliary agent, and 30 to 60 parts of a regulating agent. The organic improving agent for the acid soil has the beneficial effects that the improving agent can increase the content of organic matters in the soil, increase the pH value of the soil, increase the effective nutrients of the soil and improve the structure of the soil; the active oligopeptide in the improving agent can form a complex compound with free heavy metal ions in the soil; the complex compound settles to the bottom layer of the soil under a leaching action, and cannot be absorbed by root systems, so that harm is reduced; hydrogen ions are neutralized, and the content of substitutable aluminium ions in a soil solution is reduced, so that the pH value of the soil is improved fundamentally; the organic improving agent for the acid soil is a high-efficiency and safe organic improving agent for the acid soil.

Description

technical field [0001] The invention relates to the field of soil conditioners, in particular to an organic conditioner for royal acidic soil. technical background [0002] Acidic soil is a general term for soil with a pH value less than 7, including brick red soil, red soil, red soil, yellow soil and dry red soil. In the tropics and subtropics of my country, acidic soils of various red or yellow soils are widely distributed. The local temperature is high, the rainfall is large, and the annual rainfall is more than 1500 mm. The action of the soil is very strong, the cycle of biomass is very rapid, the base is highly unsaturated, the pH is generally 4.5-6.0, and iron and aluminum oxides are obviously accumulated, and the soil is acidic and lean. Soil acidification usually refers to the process of increasing hydrogen ions in the soil, or the process of soil acidity from low to high, and it is a continuous natural process. There are some natural acid formation processes in the...
