Problems solved by technology

[0003] Soil problems also include soil compaction, acidification and other issues. Soil conditioners can be used to improve and improve the soil. The existing soil conditioners have poor improvement effects, and usually only one soil conditioner can solve one soil problem. Solve multiple problems at the same time
Moreover, in the process of improving the soil, the soil conditioner is used in large amounts, the treatment cost is high and the repair time is long, which is easy to cause pollution transfer

preparation example Construction

[0044] Such as figure 1 Shown, according to the preparation method of the acidic soil conditioner of the second aspect embodiment of the present invention, comprises the following steps:

[0045] Step S10, drying and pulverizing the potassium feldspar, dolomite and quicklime respectively, and mixing them uniformly;

[0046] Step S20, calcining the homogeneously mixed material at high temperature, and cooling with high-pressure air after the calcination;

[0047] Step S30, adding bamboo charcoal particles, weathered coal and dispersant to pulverize and mix evenly;

[0048] Step S40, heating and stirring the uniformly mixed material;

[0049] Step S50, after cooling to room temperature, add water retaining agent, humate, calcium magnesium phosphate fertilizer and ammonium borate, add ethanol and adjust the pH to 6-8, and stir evenly within the range of 20-30°C;

[0050] Step S60, after centrifuging, filtering, drying and pulverizing, adding emulsifier and solidifying agent to...

Embodiment 1

[0065] First, 20 parts of potassium feldspar, 10 parts of dolomite and 5 parts of quicklime were dried and pulverized, and mixed uniformly. After the uniformly mixed materials were passed through a 40-mesh sieve, they were calcined at 950°C at a high temperature. cold.

[0066] Then, take out the mixed material, add 5 parts of bamboo charcoal particles, 5 parts of weathered coal and 2 parts of dispersant, and further pulverize to improve the mixing uniformity.

[0067] Next, the homogeneously mixed material was stirred while being heated at 70°C.

[0068] Secondly, after cooling the material to room temperature, add 3 parts of water-retaining agent, 5 parts of humate, 1 part of calcium magnesium phosphate fertilizer and 1 part of ammonium borate, add ethanol and adjust the pH to 6-8, and mechanically Stir well.

[0069] Finally, after centrifugation, filtration, drying and crushing, 5 parts of emulsifier and 3 parts of curing agent are added to make granules or powder to obt...

Embodiment 2

[0071] First, 30 parts of potassium feldspar, 15 parts of dolomite, and 20 parts of quicklime were dried and pulverized, and then mixed uniformly. After the uniformly mixed materials were passed through a 40-mesh sieve, they were calcined at 950°C at a high temperature. cold.

[0072] Next, take out the mixed material and add 10 parts of bamboo charcoal particles, 10 parts of weathered coal and 5 parts of dispersant, and further pulverize to improve the mixing uniformity.

[0073] Next, the homogeneously mixed material was stirred while being heated at 70°C.

[0074] Secondly, after cooling the material to room temperature, add 5 parts of water-retaining agent, 10 parts of humate, 2 parts of calcium magnesium phosphate fertilizer and 2 parts of ammonium borate, add ethanol and adjust the pH to 6-8, and mechanically Stir well.

[0075] Finally, after centrifugation, filtration, drying and pulverization, 10 parts of emulsifier and 5 parts of curing agent are added to make gran...

Abstract

The invention provides an acid soil conditioner, a preparation method and a soil improvement method of the acid soil conditioner. The acid soil conditioner comprises, by weight, 20-30 parts of potassium feldspar, 10-15 parts of dolomite, 5-20 parts of quicklime, 5-10 parts of weathered coal, 5-10 parts of bamboo charcoal particles, 5-10 parts of humate, 1-2 parts of calcium-magnesium-phosphate fertilizer, 1-2 parts of ammonium borate, 2-5 parts of dispersing agent, 3-5 parts of water-retaining agent, 5-10 parts of emulsifier and 3-5 parts of curing agent. By means of the acid soil conditioner,the acid soil can be adjusted, heavy metal is adsorbed, the gas permeability and water-retaining property of soil are improved, and resources are saved.

Description

technical field [0001] The invention relates to the technical field of soil fertilizers, more specifically, to an acidic soil conditioner, a preparation method thereof, and a soil improvement method. Background technique [0002] With the development of industry, soil pollution is becoming more and more serious, which not only affects the yield and quality of crops, but also endangers human health. People pay more and more attention to the problem of soil pollution. [0003] Soil problems also include soil compaction, acidification and other issues. Soil conditioners can be used to improve and improve the soil. The existing soil conditioners have poor improvement effects, and usually only one soil conditioner can solve one soil problem. Solve multiple problems at the same time. Moreover, in the process of improving the soil, the soil conditioner is used in large quantities, the treatment cost is high and the repair time is long, which is easy to cause pollution transfer. ...
