Embodiment 1

[0044] Embodiment 1 basic performance detection method

[0045] Determination of sulfonation degree:

[0046] Weigh with an analytical balance and heat to dissolve to accurately prepare 0.001M CTAB solution;

[0047] Weigh 0.2g of sulfonated humic acid sample, add it into 500mL of distilled water to swell for 12 hours, then dilute to 1L;

[0048] Take 10mL sulfonated humic acid sample solution and add 30mL distilled water to dilute, and titrate with 0.001M CTAB solution;

[0049] During the titration, the conductivity was measured with a conductivity meter until the conductivity vs. CTAB solution volume curve showed an obvious turning point and terminated;

[0050] Calculate the sulfonation degree=103CV / m×100%, C is the CTAB concentration (mol / L), V is the volume (L) of the turning point CTAB, and m is the lignite sulfonated humic acid mass (g).

[0051] Surface tension measurement

[0052] Accurately prepare 1% (w / v) humic acid / sulfonated humic acid, and use SITA t-100 su...

Embodiment 2

[0058] The preparation of embodiment 2 brown coal humate potassium

[0059] Use a crusher to crush the lignite to fine particles below 15 mesh;

[0060] Add the fine particles to 0.6 times the mass of 20% H 2 O 2 In the solution, stir at 50 degrees Celsius for 30 minutes;

[0061] The obtained mixture was added to 1.5 times the mass of 1.5% KOH aqueous solution, and the stirring was continued for 30 minutes at 60 degrees Celsius;

[0062] The solid was removed by centrifugation and filtered, and concentrated HCl was added to the obtained filtrate with stirring to adjust the pH to a large amount of black precipitation;

[0063] The precipitated precipitate is filtered and dried, and the obtained filter cake is the lignite potassium humate.

[0064] In addition, upon verification by the applicant, H 2 O 2 Oxidation is not an essential step, and removing this step will reduce the yield by about 10%; in practice, this step can be chosen according to the raw material compositio...

Embodiment 3

[0065] The preparation of embodiment 3 sulfonated lignite potassium humate

[0066] Dissolve potassium lignite humate in 10 times the mass of water, add 1% mass of H 2 SO 4 and 4% mass K 2 SO 3 , and reacted for 2 hours at 50 degrees Celsius;

[0067] The solution was dried to obtain potassium sulfonated lignite humate product (1).

[0068] Use 8%H 2 SO 4 Sulfonation is carried out under similar conditions to obtain sulfonated lignite potassium humate product (2).

[0069] Use 5%K 2 SO 3 Sulfonation is carried out under similar conditions to obtain sulfonated lignite potassium humate product (3).

[0070] Use 3%H 2 SO 4 and 3%K 2 SO 3 Sulfonation is carried out under similar conditions to obtain sulfonated lignite potassium humate product (4).

Abstract

The invention relates to soil conditioners and methods. A micro-powder soil conditioner is prepared from the following components (by weight): natural peat soil, humic acid, wormcast powder, amino acid, potash fertilizer, urea and microorganism compound zymophyte powder, wherein the humic acid is sulfonated lignite humic acid, and the sulfonated lignite humic acid is prepared by sulfonating lignite humic acid. The product disclosed by the invention has a very good fusion effect with soil, is used for improving soil acid, viscosity, saline-alkali soil and other obstacle factors and increasing the content of soil organic matters, so that the soil quality and the production capacity are improved, and the product has the effect of rapidly increasing the soil organic matters and fertility.

Description

technical field [0001] The invention relates to soil improvement preparations and methods, in particular to a micropowder soil conditioner and a preparation method thereof. Background technique [0002] Soil is composed of minerals, animals and plants from weathering of rocks, organic matter produced by the decomposition of microbial residues, soil organisms (solid phase substances), water (liquid phase substances), air (gas phase substances), oxidized humus, etc. Solid matter includes soil minerals, organic matter, and nutrients obtained by microorganisms through photoinhibition and sterilization. Liquid matter mainly refers to soil moisture. Gas is the air that exists in the pores of the soil. These three types of substances in the soil constitute a contradictory unity. They are interconnected and restrict each other, provide the necessary living conditions for crops, and are the material basis of soil fertility. [0003] Soil pollution not only directly leads to the r...
