Embodiment 1

[0037] The high-sulfur coal gangue used as the main raw material in this embodiment was collected from a coal mine affiliated to Shanxi Tongmei Group, which produces high-sulfur coal. The basic properties of high-sulfur coal gangue are as follows: SiO 2 24.56%, Al 2 o 3 18.53%, SO 3 3.27%, CaO 2.12%, Fe 2 o 3 3.92%, MgO 0.43%, K 2 O 0.36%, NaO 0.33%, P 2 o 5 0.85%, MnO 0.071%, pH4.76, organic matter 34.5%.

[0038] First use a crusher to crush the high-sulfur coal gangue into small pieces below 50mm, then use a high-efficiency crusher to grind it, pass it through a 200-mesh sieve, and treat it with ultrasonic waves at a frequency of 60KHz for 30 minutes.

[0039] Preparation of Thiobacillus thiooxidans bacteria liquid: culture medium: (NH 4 ) 2 SO 4 0.2g, KH 2 PO 4 3g, Elemental S 10g, MgSO 4 ·7H 2 O 0.5g, CaCl 2 2H 2 O 0.25g, trace element solution 5ml, pH=2.4, distilled water 1000ml. Culture conditions: 30°C, 120r / min constant temperature shaker. Cu...

Embodiment 2

[0061] The high-sulfur coal gangue used as the main raw material in this embodiment is collected from a coal mine affiliated to Shanxi Lu'an Group, which produces high-sulfur coal. The basic properties of high-sulfur coal gangue are as follows: SiO 2 27.12%, Al 2 o 3 17.21%, SO 3 4.12%, CaO 2.52%, Fe 2 o 3 3.55%, MgO 0.35%, K 2 O 0.32%, NaO 0.31%, P 2 o 5 0.65%, MnO 0.056%, pH4.45, organic matter 36.9%.

[0062] First use a crusher to crush the high-sulfur coal gangue into small pieces below 50mm, then use a high-efficiency crusher to grind it, pass it through a 200-mesh sieve, and treat it with ultrasonic waves at a frequency of 60KHz for 30 minutes.

[0063] Get 40 parts by volume of the Thiobacillus thiooxidans bacterium liquid cultivated in Example 1, and mix with 40 parts by volume of the mixed bacterium liquid cultivated in Example 1 to become a composite microbial bacterium liquid. Adjust the concentration of the compound microbial solution to not less tha...

Abstract

The invention discloses a saline-alkali soil biological improved fertilizer based on high-sulfur gangue. The saline-alkali soil biological improved fertilizer is prepared from the following components in parts by weight: 50-60 parts of high-sulfur gangue microbial fermentation product, 20-30 parts of compost cow manure or chicken manure, 1-2 parts of citric acid, 1-2 parts of oxalic acid, 2-4 parts of urea, 2-4 parts of ammonium sulfate, 2-4 parts of monoammonium phosphate, 1-3 parts of potassium sulphate, 2-5 parts of ferrous sulfate, 1-2 parts of zinc sulfate, 1-2 parts of manganese sulfate and 1-10 parts of bentonite, wherein the high-sulfur gangue microbial fermentation product is a product obtained by performing activating treatment on the high-sulfur gangue by a compound microorganism bacterium solution composed of thiobacillus thiooxidans, bacillus subtilis, bacillus megatherium, bacillus mucilaginosus and enterococcus faecalis. The resource utilization of the high-sulfur gangue is realized, the improvement of the inland saline land can be promoted, the crop yield can be increased and the entironment can be improved.

Description

technical field [0001] The invention relates to a biologically improved fertilizer for saline-alkali land, in particular to a special biologically improved fertilizer suitable for use in inland saline-alkali land in my country, and a preparation method for the biologically improved fertilizer. Background technique [0002] Coal gangue is solid waste generated during coal production and cleaning, and its main component is SiO 2 and Al 2 o 3 , also contains varying amounts of Fe 2 o 3 , CaO, MgO, K 2 O.P 2 o 5 , SO 3 And trace elements such as Fe, Mn, Cu, Zn, and a certain amount of humic acid. The emission of coal gangue is equivalent to about 10% of coal production. my country emits nearly 100 million tons of coal gangue every year. At present, it has accumulated more than 3 billion tons of coal gangue, covering an area of ​​about 12,000 hectares. It is currently the industry with the largest emission in my country. one of solid waste. A large amount of coal gangue ...
