Problems solved by technology

The impurity removal process will consume a large amount of external energy and materials, and will produce a large amount of environmental pollutants such as waste water, waste acid, organic solvents, and waste residues with high salt content, which will cause harm to the environment.
These problems have led to a large amount of low-grade attapulgite being piled up in the open air. Under the conditions of wind, sun, and rainfall, it will be blown away by the wind or lost to the surrounding environment by rain, which not only causes a waste of resources, but also causes damage to the surrounding environment. harm

preparation example Construction

[0034] The preparation method of potassium conditioner is:

[0035] After the low-grade attapulgite is pulverized, the above-prepared crop straw charcoal and the low-grade attapulgite are uniformly mixed in a weight ratio of 1:0.1-1:0.3 to obtain a potassium conditioner.

[0036] Among them, the low-grade attapulgite is naturally occurring or abandoned attapulgite tailings after physical beneficiation, and the attapulgite content is 20-50% by weight.

[0037] The particle size of the pulverized low-grade attapulgite is 0.1-8mm.

[0038] When in use, sprinkle the potassium conditioner on the surface of the acidic soil in organic agriculture at an application rate of 300-500kg / mu, and plow to fully mix the potassium conditioner with the field soil. It can regulate the potassium content in organic agricultural acidic soil: increase the potassium content of organic agricultural acidic soil; reduce the potassium leaching loss of organic agricultural acidic soil; it can also increase...

Embodiment 1

[0040] Example 1 Preparation of Peanut Straw Charcoal

[0041] Fill the whole plant of peanut stalks after natural air-drying (a small amount of root system on the peanut stalks does not need to be removed) into the carbonization furnace, step on it while loading, cover the furnace cover after filling, and insert a thermometer through the small hole in the center of the furnace cover The progress of the pyrolysis process can be controlled by changing the temperature. The peanut straw was ignited through the furnace door below the carbonization furnace, and the furnace door was closed after burning for 5 minutes, so that the peanut straw was pyrolyzed in the carbonization furnace by itself. During the pyrolysis process, the anaerobic environment and pyrolysis temperature of the carbonization furnace are maintained by controlling the air intake. In this embodiment, the pyrolysis temperature is controlled at 350° C., and the pyrolysis process is completed when no smoke is genera...

Embodiment 2

[0042] Example 2 Preparation of corn stalk charcoal

[0043] Use a guillotine to cut the naturally air-dried corn stalks into stalks of ≤20cm, fill the straws into the carbonization furnace, step on them while loading them, cover the furnace cover after filling, and insert them through the small hole in the center of the furnace cover A thermometer is used to control the progress of the pyrolysis process through temperature changes. The corn stalks were ignited through the furnace door below the carbonization furnace, and the furnace door was closed after burning for 5 minutes, so that the corn stalks were pyrolyzed in the carbonization furnace. During the pyrolysis process, the anaerobic environment and pyrolysis temperature of the carbonization furnace are maintained by controlling the air intake. In this embodiment, the pyrolysis temperature is controlled at 400° C., and the pyrolysis process is completed when no smoke is generated. After the pyrolysis is completed, all t...

Abstract

The invention provides an organic agricultural acidic soil potassium conditioner. The active ingredients of the organic agricultural acidic soil potassium conditioner are crop straw charcoal and low-grade attapulgite. The weight ratio of the crop straw charcoal to the low-grade attapulgite is 1:0.1-0.3. The potassium conditioner prepared by the present invention not only realizes the resource utilization of crop straw and low-grade attapulgite, but also utilizes the synergistic effect between crop straw charcoal and low-grade attapulgite to regulate potassium and acidity in organic agricultural acidic soil. Improvement and calcium and magnesium fertility enhancements open up new avenues. It can be said that the potassium conditioner in the present invention is a high-efficiency acidic soil conditioner with both potassium conditioning and soil improvement.

Description

technical field [0001] The invention relates to an acidic soil potassium conditioner for organic agriculture. Background technique [0002] Potassium is one of the three essential elements for plant growth. It plays an important role in physiological processes such as plant growth, development, metabolism, and stress resistance. It is also a quality element that plays an extremely important role in ensuring crop quality. A large area of ​​acidic soil is distributed in the tropical and subtropical regions south of the Yangtze River in my country. Due to the influence of pedogenesis, the potassium content of acidic soil is generally low. Due to the intensive planting of cultivated land in our country for many years and people's lack of attention to the supplement of potassium fertilizer in farmland, potassium deficiency has generally appeared in acidic soils. In some areas, potassium-deficient soil has accounted for more than 70% of the total cultivated land area. Organic agr...
