preparation example Construction

[0061] A preparation method of a soil conditioner, which comprises the following raw material components by weight:

[0062]

[0063] The pH value of this formula reaches 11, and the use of this formula can increase the pH value of the soil. The soil is acidified due to the long-term excessive use of chemical fertilizers and the impact of acid rain. The acidification of the soil leads to a series of problems in the soil, such as the destruction of the soil structure, soil compaction, low utilization rate of soil nutrients, and increase of harmful substances in the soil. The use of this formula can increase the pH value of the soil and increase the yield of crops. Moreover, the increase of pH value can passivate heavy metals such as chromium and nickel in the soil, reduce the activity, and the heavy metals in the free state can be absorbed by bacteria, thereby reducing the absorption of heavy metals by crops and improving the quality of crops.

[0064] And by screening the ...

Embodiment approach

[0068] As a preferred embodiment, it includes the following raw material components in parts by weight:

[0069]

[0070] As a preferred embodiment, it includes the following steps:

[0071] Step 1, screening, purifying, and expanding the culture of bacteria in the surface sludge in the septic tank to obtain the culture solution of the septic tank sludge strain;

[0072] Step 2, centrifuging the septic tank sludge bacterial strain culture solution, drying and pulverizing, and passing through a 200-mesh sieve to obtain septic tank sludge bacterial powder;

[0073] Step 3, put septic tank sludge powder, oyster shell powder, dolomite powder, biochar, vegetable leaf powder, limestone particles and vermicompost powder into a granulator according to the weight ratio, mix and granulate to obtain the desired soil conditioner.

[0074] As a kind of preferred embodiment, the screening method of the bacterial classification in the surface layer sludge in the septic tank comprises th...

Abstract

The invention discloses a preparation method and a preparation device of a soil conditioner, and belongs to the technical field of soil improvement, wherein the method comprises the steps: screening, culturing, separating, drying and crushing strains in sludge on the surface layer of a septic tank to obtain septic tank sludge bacterial powder; and finally, mixing and granulating 20-30 parts by weight of septic tank sludge bacterial powder, 10-20 parts by weight of oyster shell powder, 5-12 parts by weight of dolomite powder, 5-10 parts by weight of charcoal, 25-30 parts by weight of vegetable leaf powder, 5-10 parts by weight of limestone particles and 5-10 parts by weight of wormcast powder. The device comprises a culture solution amplification culture device, a centrifugal separator and a stirring granulator, the stirring granulator is provided with a stirring chamber, a discharge port and a disc cutter, and the disc cutter is arranged on the outer wall of the stirring chamber in a sleeving mode. The soil conditioner has the beneficial effects that the pH value of the soil conditioner reaches 11, the pH value of soil can be increased, various problems caused by soil acidification are solved, and the crop yield is increased. And the pH value is increased, so that chromium, nickel and other heavy metals in the soil are passivated, the activity is reduced, and the heavy metal absorption of crops is reduced.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a method for preparing a soil conditioner and a preparation device thereof. Background technique [0002] Acidic soil is a general term for soil with a pH value less than 7. It is mostly distributed in tropical and subtropical regions of my country, and is often caused by environmental (rainwater and air) pollution, self-poisoning, and unreasonable farming patterns. Acidic soil is the most typical and widespread obstacle soil in my country. Its existence seriously affects the growth of plants, leading to a series of problems, such as the destruction of soil structure, soil compaction, low utilization rate of soil nutrients, and increase of harmful substances in the soil. In particular, soil acidification can stimulate the activity of heavy metal elements in the soil, which not only affects the growth of crops, but also endangers the health of humans or animals through the...
