Embodiment 1

[0025] (1) The raw materials are put into the co-heating furnace according to the ratio of fresh chicken manure 70: ironmaking blast furnace steel slag powder 10: diatomite 10: boron mud 10 for co-heating;

[0026] (2) Spray 10% potassium hydroxide aqueous solution, the ratio of 10% potassium hydroxide aqueous solution is 5, spray once every 15 minutes, and finish spraying 5 times of one component;

[0027] (3) The internal temperature of the co-heating furnace is adjusted to 200-280°C, and the co-heating time is controlled at 45 minutes for low-temperature carbonization;

[0028] (4) Place and cool the material;

[0029] (5) Sieving the material;

[0030] (6) Pack the materials.

Embodiment 2

[0032] (1) The raw materials are put into the co-heating furnace according to the ratio of fresh chicken manure 70: ironmaking blast furnace steel slag powder 10: diatomite 10: boron mud 10 for co-heating;

[0033] (2) Spray 10% potassium hydroxide aqueous solution, the ratio of 10% potassium hydroxide aqueous solution is 5, spray once every 15 minutes, and finish spraying 5 times of one component;

[0034] (3) The internal temperature of the co-heating furnace is adjusted to 280-350°C, and the co-heating time is controlled at 60 minutes for low-temperature carbonization;

[0035] (4) Place and cool the material;

[0036] (5) Sieving the material;

[0037] (6) Pack the materials.

[0038] Due to the relatively high water content of the raw materials, the auger is used to convey the raw materials after they are mixed, which has an auxiliary effect on the uniform mixing of the raw materials.

[0039] In actual production, it is found that when the temperature is lower than 20...

Abstract

The technical scheme provided by the invention is as follows: the formula of the conditioner for improving the acid soil by chicken manure production comprises fresh chicken manure, ironmaking blast furnace steel slag powder, diatomite, boric sludge and a 10% potassium hydroxide aqueous solution; the method comprises the following steps: (1) raw material mixing: mixing raw materials in proportion; (2) co-heating: putting the raw materials into a co-heating furnace for co-heating, and carrying out low-temperature carbonization; (3) cooling; (4) screening; and (5) packaging. The invention has the following advantages: the two-way neutralization is carried out simultaneously from two directions of active acid and latent acid, and the main effect is to neutralize soil active acid in the early stage and stabilize soil gleying acid in the later stage. The soil PH value is mildly balanced, so that crop growth is facilitated, and continuous cropping and continuous cropping growth obstacles of crops are relieved; in addition, the fresh chicken manure, the diatomite and the bentonite can play a very good heat transfer role in the co-heating process to ensure that the raw materials are uniformly heated, and meanwhile, certain explosion-proof and flame-retardant roles are achieved, so that the production safety can be ensured to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a formula and method for producing improved acidic soil conditioner by using chicken manure. Background technique [0002] The widespread acidification of farmland soil in China is very serious. According to the official announcement of the state, the area of ​​cultivated land in my country is 1.86 billion mu, of which the area of ​​soil acidification is more than 200 million mu, which does not include the area of ​​soil acidification within our growing facility agriculture. From the 1980s to the new century, the average pH value of farmland soil across the country dropped by 0.5 units. The soil that was mainly neutral in the 1980s has basically become acidic or medium-strong acidic soil, that is to say General acidification. [0003] There are two main types of soil acidification: [0004] Active acid: [0005] Active acid is a direct reflection of the concentration...
