Embodiment 1

[0030] Take alkaline straw pulp black liquor, lower the temperature of the black liquor to 30°C, add Saccharomyces cerevisiae AS 2.23 strains, the amount of which is 1 / 20 of the black liquor volume, mix evenly, store at room temperature for 8 days, and make the black liquor The solution is acidified to a pH value of 9.0, and the obtained brown-yellow anaerobic black liquor has a sweet smell; then, 92% sulfuric acid is uniformly and slowly added to the anaerobic black liquor, and the process of adding is fully stirred until the pH of the black liquor The value is 7.0; under normal pressure, slowly add 65% nitric acid solution with 2% black liquor solid content into the black liquor, stir, raise the temperature to 70°C and keep it for 1 hour, then slowly add 10 65% nitric acid solution with black liquor solid content, boiled for 2 hours. During the addition of nitric acid solution, the NO produced 2 Absorb in time with lye. After the nitration reaction is finished, filter with...

Embodiment 2

[0034] Take alkaline straw pulp black liquor, lower the temperature of the black liquor to 35°C, add Saccharomyces cerevisiae AS 2.24 strain, the amount of the incorporation is 1 / 25 of the black liquor volume, mix evenly, store at room temperature for 5 days, and make the black liquor The solution is acidified to a pH value of 8.0 to obtain brownish-yellow anaerobic black liquor with a sweet smell; then, 95% sulfuric acid is evenly and slowly added to the anaerobic black liquor, and the process of adding is fully stirred until the pH of the black liquor The value is 6.0; under normal pressure, slowly add 60% nitric acid solution with 3% black liquor solid content into the black liquor, stir, raise the temperature to 70°C and keep it for 0.5 hours, then slowly add 5 60% nitric acid solution with black liquor solid content, boiled for 2 hours. During the addition of nitric acid solution, the NO produced 2 Absorb in time with lye. After the nitration reaction is finished, filte...

Embodiment 3

[0038] Take soda straw pulp black liquor, lower the temperature of the black liquor to 45°C, add S. The solution is acidified to a pH value of 85, and the obtained brown-yellow anaerobic black liquor has a sweet smell; then, 98% sulfuric acid is uniformly and slowly added to the anaerobic black liquor, and the process of adding is fully stirred until the pH of the black liquor is The value is 6.5; under normal pressure, slowly add 65% nitric acid solution with 5% black liquor solid content into the black liquor, stir, raise the temperature to 70°C and keep it for 1 hour, then slowly add 8 65% nitric acid solution with black liquor solid content, boiled for 2 hours. During the addition of nitric acid solution, the NO produced 2 Absorb in time with lye. After the nitration reaction is finished, filter with a sieve, and dry the filtrate to obtain a powder for use.

[0039] Take soda straw pulp black liquor to acidify lignin, add 4 times the weight of water, stir, make the mixt...

Abstract

This invention relates to an apple tree nutrient injection and the method for making the same, belonging to the fertilizer technology field. The acidity of the said apple tree nutrient injection is usually pH 2-3, and the procedures comprise: treat the black liquor by biochemistry process to produce the powder, use the filter liquor of lignin and iron chelate as the mother liquid, dissolve the saccharose, urea, ZnSO4 and borax in this mother liquid, mix this liquid with the above powder to produce the product. This invention processes the straw pulp black liquor and lignin, with a lot of consumption of straw pulp black liquor and lignin, to transform them to be usable fertilizer, which greatly decrease the pollution, resulting economical and environmental benefits. Besides, the produced fertilizer is used by direct injection, which avoids the disadvantages of low fertilizer utilization coefficient and environmental pollution brought by the traditional fertilizer application method, and overcomes the problems of low effective time and single nutrient of the traditional fertilizer.

Description

technical field [0001] The invention relates to an apple tree nutrient injection and a preparation method thereof, belonging to the technical field of fertilizers. Background technique [0002] Fruit trees are perennial woody plants with strong branch skeletons and the characteristics of storing nutrients. The root system of fruit trees is well developed, and the distribution is deep and wide. Once they have been planted for many years, they will selectively absorb nutrients from the same soil for a long time, which will easily lead to insufficient supply of soil nutrients, and physiological obstacles such as nutritional disorders and deficiencies. Therefore, carrying out fertilization management to fruit trees is one of important links in fruit tree cultivation. [0003] The traditional method of fertilizing fruit trees adopts soil fertilization and foliar spray fertilizer. These fertilization methods have many defects, such as soil fertilization with a large amount of fer...
