Embodiment 1

[0039] In the production and drying process of the fertilizer factory, the main fuel of the boiler is sugar factory filter mud and bagasse. 1T of fuel is combined with 100Kg of shells for heating. After testing, the ash discharged after combustion is passed through a screening machine with an aperture of 1mm. Sieve, the sieve is repeatedly crushed, so that most of the sieve can pass through the sieve, and the undersieve is tested after being stirred evenly. It can be known that the calcium content is 13.8%, the potassium content is 4.21%, and the pH is 8.52. Get ashes.

[0040]The wood bran in the sawmill controls the moisture within 20%, directly presses it into rods, and then sends it to the carbonization machine for carbonization at 500°C. After the charcoal is formed, the charcoal is taken out for crushing and sieving. The sieve is 1mm in diameter. Repeat crushing and sieving until all the oversize passes through the 1mm sieve.

Sieve, the sieve is repeatedly crushed, so that most of the sieve can pass through the sieve, and the undersieve is evenly stirred and tested. It can be known that the calcium content is 23.3%, the potassium content is 3.31%, and the pH is 9.98. Get ashes.

[0047] After the straw is dried and crushed, it is pressed into rods, and then sent to the carbonization machine for carbonization at 300°C. After the charcoal is formed, the charcoal is taken out for crushing and sieving. , until the sieve all through the 2mm sieve.

[0053] In the production and drying process of the fertilizer factory, the main fuel of the boiler is sugar factory filter mud and bagasse. 1T of fuel is used together with 300Kg of shells for combustion and heating. After testing, the ash discharged after combustion is passed through a screening machine with an aperture of 1mm. Sieve, the sieve is repeatedly crushed, so that most of the sieve can pass through the sieve, and the undersieve is tested after being stirred evenly. It can be known that the calcium content is 32%, the potassium content is 3.86%, and the pH is 8.75. Get ashes.

[0054] Wood scraps are dried and crushed, pressed into rods, and then sent to a carbonization machine for carbonization at 600°C. After charcoal is formed, the charcoal is taken out for crushing and sieving. The sieve is 1mm in diameter, and the crushing and sifting are repeated continuously. Sieve until all the sieves pass through a 3mm sieve.

Abstract

The invention discloses a soil conditioner and a preparation method thereof. The soil conditioner is prepared by mixing boiler ash, a carbon material, a plant vinegar liquid, waste molasses and water according to a mass ratio of 30-80:20-50:0.5-2:0.5-2:12-27. Water is used to adjust the total water content to 15-30% and assist reduction of flying of dusts. The soil conditioner saves energy and mineral product resources, realizes shell waste treatment and soil heavy metal passivation treatment, almost realizes zero discharge of ashes, effectively passivates soil metals and recovers the microbial ecology, has crop growth promotion and disease prevention effects, and realizes changing of wastes into valuables.

Description

【Technical field】 [0001] The invention relates to a soil conditioning agent and a preparation method thereof, belonging to the technical field of soil conditioning. 【Background technique】 [0002] After shellfish seafood is processed and consumed by humans, there are often a large number of shells left, which have already caused a load on the environment under the condition of slow digestion under natural conditions. From the perspective of environmental protection, garbage is just waste that has been put in the wrong place. Shells contain a lot of calcium and become alkaline after calcination. If shells can be processed to turn waste into treasure, it will be a good outlet for waste. [0003] The soil in southern China is generally acidic, especially over the years when a large amount of acidic fertilizers have been used. The acidity of the soil has exceeded the weak acid range that most crops prefer, and even some soils have reached strong acidity, which has a great impact...
