Problems solved by technology

[0003]At present, most manufacturers in the world mainly use chemical hydrolysis to produce seaweed fertilizer. The biggest disadvantage of this method is that strong alkali and high temperature will destroy the activity of seaweed endogenous substances, making the Many nutrients are damaged, and the effect of use is not good

Embodiment 1

[0026] The specific preparation method of foliar fertilizer is as follows: 1) Select 500g of macroalgae from which miscellaneous algae and foreign matter have been removed, wash it, and grind and homogenize it in 4000g of sulfuric acid solution with pH4 to obtain the seaweed homogenate raw material; 2) Seaweed homogenate raw material Mix with distilled water, cellulase and pectinase at a mass ratio of 1:5:0.01:0.01 and stir evenly, then heat in a water bath at 40°C for 4 hours; then heat up to 80°C for 30 minutes to obtain an enzymolysis mixture; 3) Filter the enzymolysis mixture after cooling, wash the filter residue twice, combine the filtrate, centrifuge at 5000r / min for 15min, and take the supernatant; 4) Ultrasonic degrade the supernatant under the condition of 150-250w -20min, sonicate into intermittent work, and cycle according to the way of working for 1s and 1s; 5) Concentrate the ultrasonically treated supernatant to 1 / 4 of the original volume by vacuum distillati...

Embodiment 2

[0028] The specific preparation method of foliar fertilizer is as follows: 1) Select 500g of Sargassum sargassum from which miscellaneous algae and foreign matter have been removed, wash, grind and homogenize in 4500g of nitric acid solution of pH2 to obtain seaweed homogenate raw material; 2) seaweed homogenate raw material Mix with distilled water, cellulase and pectinase at a mass ratio of 1:7:0.02:0.02 and stir evenly, then heat in a water bath at 43°C for 3 hours; then raise the temperature to 80°C for 40 minutes to obtain an enzymolysis mixture; 3) Filter the enzymolysis mixture after cooling, wash the filter residue twice, combine the filtrate, centrifuge at 5000r / min for 18min, and take the supernatant; 4) Ultrasonicate the supernatant under the condition of 150-250w for 15 -20min, sonicate into intermittent work, and cycle according to the way of working for 1s and 1s; 5) Distill and concentrate the ultrasonically treated supernatant to 1 / 5 of the original volume,...

Embodiment 3

[0030] The specific preparation method of foliar fertilizer is as follows: 1) Select 500g of Ascophyllum nodosum from which miscellaneous algae and foreign matter have been removed, wash it, and grind and homogenize it in 5000g of acetic acid solution of pH3 to obtain the seaweed homogenate raw material; 2) Homogenize the seaweed Mix the raw materials with distilled water, cellulase and pectinase at a mass ratio of 1:6.5:0.015:0.015 and stir evenly, then heat in a water bath at 45°C for 2.5h; then raise the temperature to 80°C for 50min to obtain the enzymolysis mixture 3) Filter the enzymolysis mixture after cooling, wash the filter residue twice, combine the filtrate, centrifuge at 5000r / min for 20min, and take the supernatant; 4) Ultrasonicate the supernatant under the condition of power of 150-250w Degrade for 15-20min, sonicate into intermittent work, and cycle according to the way of working for 1s and 1s; 5) Distill and concentrate the ultrasonically treated supern...

Abstract

The invention discloses a method for preparing an active algae extract foliar fertilizer. The method comprises the following steps: using natural algae as a raw material, grinding in a dilute acid solution with PH2-4 and homogenating; then, adding cellulase and pectinase to carry out enzymolysis, centrifuging collected filtrate to remove non-soluble impurities, carrying ultrasonic degrading to obtain small-molecular substances , subsequently concentrating, regulating the PH value to 5.0-7.0, inoculating pre-cultured probiotic bacteria, conventionally fermenting, and using fermented pulp as the active algae extract foliar fertilizer. The foliar fertilizer has endogenous plant growth substances, such as plant auxin, cytokinin and gibberellin, has protein amino acids capable of being directly absorbed and used by plants as nutrients, other certain free amino acids, peptides, nucleotides and the like, and has algae polyphenols, flavonoid compounds, terpenoid compounds and the like. The plant resilience, such as drought resistance, cold resistance and disease and insect resistance can be enhanced under the condition of improving the yield.

Description

technical field [0001] The invention relates to a method for preparing fertilizer, in particular to a method for preparing active seaweed extract liquid foliar fertilizer. Background technique [0002] With the development of modern agriculture, all kinds of high-quality and high-efficiency new fertilizers are constantly emerging. Seaweed fertilizer, as a rookie of new fertilizers, will soon become the new favorite of the market once it appears. Seaweed fertilizer has comprehensive nutrition, unique efficacy, natural pollution-free characteristics and The extremely high cost performance has led to rapid development, and is known as the fourth-generation fertilizer after organic fertilizers, chemical fertilizers, and biological fertilizers. The biggest advantage of seaweed liquid foliar fertilizers is the diversity of active ingredients in the product, and all of them can be absorbed and utilized by plants. [0003] At present, most manufacturers in the world mainly use chem...
