Problems solved by technology

Although some of the above measures have achieved good results, most of these measures have a single improvement effect, and it is difficult to fundamentally solve the problem
At the same time, the labor force is large, the cost is high, the improvement time is long, and it is not easy to promote and apply on a large scale
[0006] my country's weathered coal resources are widely distributed and have large reserves. Many provinces have abundant coal resources. However, due to the low calorific value of weathered coal, weathered coal has not been used as a mineral resource in the past and has been allowed to be discarded.

Embodiment 1

[0027] With 2.1Kg of unactivated humic acid A and 0.87Kg of sieved green waste B, fully mix A and B. Then, add 0.0012Kg of copper sulfate oxidant and 0.0018Kg of synergist (composed of two or more adhesives such as hide glue, soybean powder, and cheese) to the mixture of A and B. Finally, put the above mixture Put it into the ball mill, adjust the rotation speed of the ball mill to 80r, and the time is 2h to generate the activated saline-alkali soil improver. The prepared saline-alkali land improving agent is bagged, measured, and stored, and can be stored for a long time, with a valid period of 5-8 years. Compared with the traditional production method of saline-alkali soil improver, this activation process can be carried out at room temperature, which can save half of the energy (traditional production methods generally require liquid heating and stirring), and this method has low requirements for reaction equipment (traditional activation method All are liquid conditions, ...

Embodiment 2

[0029] 3Kg unactivated humic acid A and 0.96Kg sieved green waste B, A and B are fully mixed. Then, add 0.002Kg of sodium hypochlorite oxidant and 0.002Kg of synergist (composed of two or more adhesives such as hide glue, soybean powder, and cheese) to the mixture of A and B. Finally, put the above mixture into In the ball mill, adjust the rotation speed of the ball mill to 90r and the time to 3h to generate the activated saline-alkali soil improver. The saline-alkali land improving agent prepared by the invention can be stored in bags, measured and put into storage for a long time, and the validity period can be 5-8 years. Compared with the traditional production method of saline-alkali soil improver, this activation process can be carried out at room temperature, which can save half of the energy (traditional production methods generally require liquid heating and stirring), and this method has low requirements for reaction equipment (traditional activation method All are l...

Embodiment 3

[0031]With 4Kg of unactivated humic acid A and 0.95Kg of sieved green waste B, fully mix A and B. Then, add 0.004Kg copper sulfate and sodium hypochlorite oxidizing agent and 0.001Kg synergist (composed of two or more adhesives such as hide glue, soybean powder, cheese casein) to the mixture of A and B Finally, the above-mentioned mixture Put it into a ball mill, adjust the rotation speed of the ball mill to 120r, and the time to 4h to generate the activated saline-alkali soil improver. The activated saline-alkali soil improver produced is bagged, measured, and put into storage. It can be stored for a long time, and the validity period can be 5-8 years. Compared with the traditional production method of saline-alkali soil improver, this activation process can be carried out at room temperature, which can save half of the energy (traditional production methods generally require liquid heating and stirring), and this method has low requirements for reaction equipment (traditiona...

Abstract

The invention relates to a multifunctional saline and alkaline land modifier and a preparation method thereof. The preparation method comprises the following steps of sufficiently blending an unactivated humic acid A, a green waste B screened by a 100-mesh sieve, an oxidant C and a decomposer D, putting the mixture in a ball grinding mill, setting the rotating speed of the ball grinding mill to be 80 to 120 r and the ball milling time to be 2 to 4 h, and thus obtaining the multifunctional saline and alkaline land modifier. The modifier is a multifunctional modifier, and can serve as a base fertilizer applied in one time, so that the labor force is saved, the physical and chemical properties of soil are improved, salt is restrained and water is retained, the modifier can be a soil modifier and can also serve as a water-retaining agent, and besides, the yield of crops can be increased.

Description

[0001] (1) Technical field [0002] The invention relates to a multifunctional saline soil improvement agent and a preparation method thereof, belonging to the technical field of saline soil improvement. [0003] (2) Background technology [0004] Saline-alkali land is a common name for saline soil, including saline soil, salinized soil, alkaline soil and alkaline soil. It means that the soil surface contains a large amount of soluble salts such as sodium chloride and sodium carbonate. It promotes the closure of plant stomata and increases the osmotic pressure of the soil solution, hinders the growth of plants, causes physiological drought in plants, causes plants to dehydrate and die, and has great harm to agricultural production. Soil is an important part of the soil ecosystem and the material basis for human survival. However, with the development of industry, the continuous expansion of irrigated land and facility cultivation area, seawater intrusion into the seashore and ...
