[0036] A preparation method of an acidic soil remediation agent, comprising the steps of:

[0037] (1) Preparation of modified white mud powder: Dry the white mud at 105°C for 2 hours, then place it in a horse boiling furnace and calcinate it at 650°C for 2.5 hours. During the calcination process, the main component of white mud, CaCO 3 and Ca(OH) 2 Decomposed into CaO. After the calcination is completed, cool to room temperature, and then place it in a grinder and grind for 30 minutes to obtain modified white mud powder, which is ready for use.

[0038] (2) Preparation of acid-reducing microparticles: mix 85 parts by weight of modified white clay powder prepared in step (1), 16 parts by weight of dicalcium ferrite and 20 parts by weight of water and stir evenly, place the obtained mixture in the Granulate into balls in a granulator to obtain acid-reducing granules for later use.

[0043] A preparation method of an acidic soil remediation agent, comprising the steps of:

[0044] (1) Preparation of modified white mud powder: Dry the white mud at 115°C for 1 hour, then place it in a horse boiling furnace and calcinate it at 500°C for 3 hours. During the calcination process, the main component of white mud, CaCO 3 and Ca(OH) 2 Decomposed into CaO. After the calcination is completed, cool to room temperature, and then place it in a grinder and grind for 20 minutes to obtain modified white clay powder, which is ready for use.

[0045] (2) Preparation of acid-reducing microparticles: mix 75 parts by weight of modified white mud powder prepared in step (1), 10 parts by weight of dicalcium ferrite and 15 parts by weight of water and stir evenly, place the obtained mixture in the Granulate into balls in a granulator to obtain acid-reducing granules for later use.

[0050] A preparation method of an acidic soil remediation agent, comprising the steps of:

[0051] (1) Preparation of modified white mud powder: Dry the white mud at 100°C for 3 hours, then place it in a horse boiling furnace and calcinate it at 750°C for 2 hours. During the calcination process, the main component of white mud, CaCO 3 and Ca(OH) 2 Decomposed into CaO. After the calcination is completed, cool to room temperature, and then place it in a grinder and grind for 10 minutes to obtain modified white clay powder, which is ready for use.

[0052] (2) Preparation of acid-reducing microparticles: mix 70 parts by weight of modified white clay powder prepared in step (1), 12 parts by weight of dicalcium ferrite and 20 parts by weight of water and stir evenly, place the obtained mixture in the Granulate into balls in a granulator to obtain acid-reducing granules for later use.

Abstract

The invention relates to the technical field of soil improvement, and discloses an acid soil remediation agent as well as a preparation method and application thereof. The remediation agent comprises the following components in parts by weight: 20-40 parts of microbial pellets, 50-70 parts of deacidification particles and 120-160 parts of organic fertilizer. The microbial pellets comprise a network matrix, polyglutamic acid, polygalacturonic acid, microbial powder and cellulose ether, and microorganisms in the microbial powder are attached to the network matrix. The deacidification particles comprise modified white mud, dicalcium ferrite and water, wherein the modified white mud is white mud powder containing calcium oxide as an active component. According to the acidic soil remediation agent disclosed by the invention, the deacidification particles taking the modified white mud and the dicalcium ferrite as main components can release alkaline substances for a long time to prevent secondary acidification of soil; and the microbial pellets can provide an ecological network system for long-term survival of microbial bacteria, and can continuously release the microbial bacteria and nutrients to the soil.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to an acidic soil remediation agent and its preparation method and application. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] In order to meet the huge food demand brought about by the rapid population growth, people increase food production by increasing the application of chemical fertilizers. However, excessive application of fertilizers, especially nitrogen fertilizers, will convert nitrogen fertilizers into nitrates during the decomposition process. When nitrates are lost, a large amount of calcium and magnesium ions in the soil will be taken away, thus causing so...
