Embodiment 1

[0056] Embodiment 1, the preparation of saline-alkali soil conditioner of the present invention

[0057] Material preparation:

[0058] Ratio of main ingredients: 100g of main ingredients include 60.0-80.0g of sludge with a water content of 60.0-90.0%, 10.0-20.0g of humus, peat or farm manure (naturally decomposed livestock manure) and 10.0-30.0g of water, In addition, add 0.1-0.5g of deodorizing and sterilizing agent composed of trichloroisocyanuric acid to deodorize and sterilize the main ingredients;

[0059] Ingredients ratio: 100.0g acrylic resin modified casein or polyacrylamide and its derivatives or lignosulfonate or cellulose derivatives;

[0060] The auxiliary material is 100.0g of compound microbial bacterial agent: the weight components of various bacterial strains are as follows: 10.0-15.0 parts of anaerobic lactic acid bacteria group, 10.0-15.0 parts of aerobic yeast group, and 10.0-15.0 parts of aerobic Gram-positive actinomycete group 10.0-15.0 parts, anaerob...

Embodiment 2

[0066] Take 6000.0g of sludge with a water content of 60.0%, 1000.0g of farm manure (naturally decomposed livestock and poultry manure) and 1000.0g of water, and add 10.0g of trichloroisocyanuric acid to deodorize the main ingredients. Made into main ingredients after sterilization;

[0067] Get 400.0g acrylic resin modified casein as auxiliary material;

[0068] Lactic acid bacteria (aerobic), yeast flora (aerobic), Gram-positive actinomycetes (aerobic), filamentous bacteria of fermentation systems (aerobic), Bacillus, nitrogen-fixing bacteria, 10.0 g each of the phosphate solubilizing bacteria and the potassium solubilizing bacteria are mixed and used as ingredients.

[0069] Prepare the main ingredients, spare auxiliary ingredients and ingredients that have been made respectively.

[0070] The main ingredient is diluted with 1-2 times the weight of water for later use; the auxiliary material is diluted with 1-2 times the weight of water for later use, and the diluted auxi...

Embodiment 3

[0071] Embodiment 3, the application of saline-alkali land improvement agent of the present invention

[0072] On the land to be treated, use a sprayer to spray the filtrate obtained in Example 1 and / or Example 2 to form a mulch film. The orifice diameter on the nozzle of the sprayer is 1.0 to 1.5mm. It is necessary to maintain a certain pressure and prevent clogged.

[0073] Stepping and shoveling should be avoided within 90 days of spraying.

[0074] Generally, it is recommended to spray saline-alkali soil improver (the weight of the filtrate after the main material, auxiliary material and ingredients are mixed with water) per mu of saline-alkali land, 10.0kg ~ 30kg. After the field pilot test, the results are shown in the table below.

[0075]

[0076]

[0077] By using the saline-alkali soil improver of the invention, the total salt content of the soil is reduced by more than 80% compared with the soil without using the saline-alkali soil improver, and the soil fert...

Abstract

The invention provides a saline-alkali soil conditioner as well as preparation and an application thereof and belongs to the technical field of ecological engineering. The saline-alkali soil conditioner comprises a main material and an auxiliary material, wherein the main material comprises sludge, humus and / or farmyard manure; the auxiliary material comprises a compound microbial agent; the compound microbial agent comprises one or more of following strains: anaerobic lactic acid bacteria, aerobic yeast, aerobic Gram-positive actinomycetes, anaerobic fermentation filamentous bacterium floras, bacillus, nitrogen-fixing bacteria, phosphate solubilizing bacteria and potassium bacteria. The invention further provides a preparation method of the saline-alkali soil conditioner, a saline-alkali soil conditioning method based on the saline-alkali soil conditioner and a compound microbial agent for saline-alkali soil conditioning. Dual purposes of ecological disposal of the sludge and long-acting conditioning of saline-alkali soil can be achieved with the adoption of the saline-alkali soil conditioner and conditioning method.

Description

technical field [0001] The invention belongs to the technical field of ecological engineering, and relates to a saline-alkali soil improver and its preparation and application. Background technique [0002] Sludge is a heterogeneous body composed of organic debris, bacteria, inorganic particles, and colloids. It is commonly found in solid sediments produced during sewage treatment and sediments formed by polluted rivers all year round. The main characteristics of sludge are high water content (up to 99%), high content of organic matter, easy to rot and smell, and the particles are finer, the specific gravity is smaller, and it is in a colloidal liquid state. Sludge is difficult to achieve complete dehydration through natural sedimentation for solid-liquid separation. Sludge treatment generally achieves sludge reduction through various treatment methods such as ocean disposal, landfill, composting, drying and incineration. However, these treatment methods are still unable t...
