Problems solved by technology

[0007] The existing fertilizer injection technology focuses more on the growth of fruit trees, but lacks attention to economic tree species such as poplar, and there is no precedent for using black liquor waste as fertilizer, so further research is needed

Embodiment 1

[0038] Lower the temperature of the black liquor to 30°C, add Saccharomyces cerevisiae AS 2.23, the amount of which is 1 / 30 of the volume of the black liquor, mix well, store at room temperature for 5 days, and acidify the black liquor to a pH value of 9.0, at this time The color of anaerobic black liquor is brownish-yellow and has a sweet smell;

[0039] Separating the bottom sludge of the anaerobic black liquor, slowly and evenly adding 92% sulfuric acid to the supernatant liquid, stirring while adding the acid, until the pH value of the black liquor is 6, and obtaining the acidified anaerobic black liquor;

[0040] Divide the acidified anaerobic black liquor into two parts and put them into the enamel reaction kettle respectively. One part is added with 25% ammonia water. The amount of ammonia water is 5 times the solid content of the anaerobic black liquor. At 2.5Mpa, the amount of compressed air is 10L / min, the reaction time is 3 hours, and then concentrated H 2 SO 4 Ad...

Embodiment 2

[0052] Lower the temperature of the black liquor to 35°C, add Saccharomyces cerevisiae AS 2.24, the amount of which is 1 / 25 of the volume of the black liquor, mix well, store at room temperature for 8 days, and acidify the black liquor to a pH of 8.5. The color of anaerobic black liquor is brownish-yellow and has a sweet smell;

[0053] Separating the bottom sludge of the anaerobic black liquor, slowly and evenly adding 95% sulfuric acid to the supernatant liquid, stirring while adding acid, until the pH value of the black liquor is 7, to obtain acidified anaerobic black liquor;

[0054] Divide the acidified anaerobic black liquor into two equal parts and put them into the enamel reaction kettle respectively. Add 10% ammonia water to one part. The amount of ammonia water is 5 times the solid content of the anaerobic black liquor. At 3.0Mpa, the amount of compressed air is 8L / min, the reaction time is 2.5 hours, then add concentrated H 2 SO 4 Adjust the pH value of the reacti...

Embodiment 3

[0066] Lower the temperature of the black liquor to 45°C, add Saccharomyces cerevisiae AS 2.240, the amount of which is 1 / 20 of the volume of the black liquor, mix well, store at room temperature for 6 days, and acidify the black liquor to a pH of 8. The color of anaerobic black liquor is brownish-yellow and has a sweet smell;

[0067] Separating the bottom sludge of the anaerobic black liquor, slowly and evenly adding 98% sulfuric acid to the supernatant liquid, stirring while adding acid, until the pH value of the black liquor is 6.5, to obtain acidified anaerobic black liquor;

[0068] Divide the acidified anaerobic black liquor into two equal parts and put them into the enamel reaction kettle respectively. Add 30% ammonia water to one part. The amount of ammonia water is 4 times the solid content of the anaerobic black liquor. At 3.2Mpa, the amount of compressed air is 5L / min, the reaction time is 2 hours, and then add concentrated H 2 SO 4 Adjust the pH value of the rea...

Abstract

The invention refers to a method which using stew plasm liquor to prepare poplar nutrient injection, belonging to fertilizer technique realm. The method mentioned above containing anaerobic acidfy of stew plasm liquor, part acidify anaerobic black liquor going by ammonization reation, nitridation and getting filter liquor after filtration, combining the two parts filter and concentration to get mother liquid, getting prodects by adding nutritious components after hydroperoxide reaction. Using this method dealing with staw plasme black liquor, transferring the getted filtrate to fertilizer for use, getting rid of staw plasme black liquor and changing waster into treasure at the same time; meanwhile, applying the getted nutrient injection to growth of poplar cellulose, solveing the traditional fertilization's disadvantages of slow effect, single nutrient, the using effect is different from the plants' hormones of chemosynthesis, especially about triploid Chinese white poplar, the tree-trunk becoming thick quickly after use it, hasing good economic benefit and environment benefit.

Description

technical field [0001] The invention relates to a method for preparing poplar nutrient injection with straw pulp black liquor, belonging to the technical field of fertilizers. Background technique [0002] The traditional fertilization method uses soil fertilization, which has many defects, such as large amount of fertilizer used in soil fertilization, nutrients are often fixed by the soil, leached and lost by rainwater, prone to volatilization and inactivation of elements, and low fertilizer utilization rate. Deficiencies such as iron deficiency are less effective; thus, the trunk injection technique was created. [0003] The trunk injection technology originated from the pesticide injection theory proposed in Japan's "Internal Treatment of Plants" in 1926. It mainly aimed at the low-use pesticide pest control technology for woody plants that was proposed because of the high cost of chemical pesticides at that time. After the 1970s, it was gradually used for the treatment ...
