Problems solved by technology

[0004] 1. Disc granulation and drum granulation belong to the wet production process. The moisture content of the product after granulation is relatively high. After granulation, high-temperature drying is often used for drying. The temperature is generally around 200°C and the duration is generally 15 minutes. The above has a great impact on the number of viable bacteria; if it is dried at room temperature, it will take a long time and affect the production efficiency;
[0005] 2. Extrusion granulation belongs to the dry production process. It is granulated by high-intensity extrusion, but at the moment of high-in

Example Embodiment

[0043] Example 1

[0044] Prepare the saline-alkali soil conditioner rich in salt-tolerant microorganisms according to the following steps:

[0045] (1) Weigh the following raw materials by weight: 1 part of salt-tolerant bacteria, 1 part of sulfur-containing substances, 13 parts of potassium humate, 15 parts of decomposed livestock and poultry manure, and 20 parts of decomposed straw;

[0046] (2) fermenting the salt-tolerant bacteria to obtain a salt-tolerant bacteria fermentation broth;

[0047] (3) After crushing and mixing the sulfur-containing substances, potassium humate, decomposed livestock and poultry manure, and decomposed straw, add it into the upper hopper 11, and introduce it into the front end of the upper inner cone 22 from the upper hopper 11, and the mixture is in the upper inner cone 22. The particles are rolled and extruded into particles, which are discharged from the rear end of the upper inner cone 22 and fall into the upper outer cylinder 21. After bei...

Example Embodiment

[0052] Example 2

[0053] This embodiment is roughly the same as Embodiment 1, except that:

[0054] The saline-alkali soil conditioner rich in salt-tolerant microorganisms includes the following raw materials in parts by weight: 2 parts of salt-tolerant bacteria, 2 parts of sulfur-containing substances, 13 parts of potassium humate, 15 parts of decomposed livestock and poultry manure, and 18 parts of decomposed straw.

Example Embodiment

[0055] Example 3

[0056] This embodiment is roughly the same as Embodiment 1, except that:

[0057] The saline-alkali soil conditioner rich in salt-tolerant microorganisms includes the following raw materials in parts by weight: 3 parts of salt-tolerant bacteria, 3 parts of sulfur-containing substances, 13 parts of potassium humate, 13 parts of decomposed livestock and poultry manure, and 18 parts of decomposed straw.

Abstract

The invention discloses a saline-alkali soil conditioner rich in salt-tolerant microorganisms and a preparation method and device thereof, the conditioner comprises salt-tolerant bacteria, a sulfur-containing substance, potassium humate, decomposed livestock and poultry manure and decomposed straw, through the cooperation of multiple salt-tolerant bacteria microorganisms, the micro-ecological environment of soil can be improved, and the buffer performance of the soil is improved; according to the preparation device, the integrated layout of modifier production is achieved, the occupied space can be saved, the drying efficiency of organic particles is improved, during preparation, the granulation step and the strain inoculation step are carried out separately, high-temperature rapid drying is carried out after wet granulation, and the production efficiency is improved. The bacterial liquid is uniformly sprayed on the organic particles dried and cooled at high temperature through the bacterial liquid opposite spraying mechanism, so that the bacterial content of the modifier is ensured, and then the modifier is dried in a normal-temperature rapid air-drying manner, so that the activity of strains is ensured, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land treatment, in particular to a saline-alkali land soil conditioner rich in salt-tolerant microorganisms and a preparation method and device thereof. Background technique [0002] my country is a country with a large population, and there is a relative shortage of arable land resources, and among the limited arable land resources, the area of ​​saline-alkali land accounts for more than 10%. The high pH and salt content of saline-alkali soils affect the normal growth of crops and lead to low crop yields. Therefore, the use of reasonable methods to control saline-alkali land is related to the sustainable development of agriculture and food security in my country. At present, many saline-alkali soil conditioners have been developed on the market. Among them, the microbial saline-alkali soil improvement has a small investment, and can use the existing nutrients in the soil to improve the mic...
