Problems solved by technology

However, most of the applications of alginic acid in agriculture exist in the form of liquid fertilizers, because in high temperature, high pressure, and high salinity environments, macromolecular seaweed polysaccharides will be damaged to a certain extent, resulting in invalidation or inactivation of active ingredients.
Although the active ingredients of seaweed have many benefits in agriculture, such as increasing production, resisting stress, promoting growth, removing soil compaction, and reducing salinization, but due to its inability to withstand high temperature and high pressure, its addition in fertilizer production is subject to many restrictions. It has not been widely developed and effectively used in our country

Embodiment 1

[0046] The high-tower compound fertilizer added with seaweed enzymolysis dry powder, the formula is as follows:

[0047] 60 kg of seaweed enzymatic hydrolysis dry powder; 230 kg of 72% monoammonium phosphate, 340 kg of 36% ammonium nitrate, 70 kg of 20.5% ammonium sulfate, 290 kg of 52% Manham potassium sulfate, 5 kg of mineral source potassium fulvic acid, 35 kg % Zinc sulfate monohydrate 5 kg.

[0048] Among them, the dry seaweed enzymatic hydrolysis powder is prepared by jointly enzymatically decomposing Ascophyllum nodosum with cellulase, pectinase and alginate lyase; in the seaweed enzymatic hydrolysis dry powder, the purity of alginic acid is ≥ 6.5%;

[0049] Ammonium nitrate is N32-P4, which is purchased from the market;

[0050] Manham potassium sulfate is K52, CI is less than 2%, purchased from the market;

[0051] Monoammonium phosphate is N12-P60, purchased from the market;

[0052] Ammonium sulfate is N20.5, purchased from the market;

[0053] Potassium fulvic ...

Embodiment 2

[0075] Seaweed enzymolysis dry powder, the preparation method is as follows:

[0076] Pretreatment: Dry the imported Ascophyllum nodosum from Northern Ireland, cut it at high speed, and then grind it into powder, soak the Ascophyllum nodosum powder in water to fully absorb water and swell;

[0077] Enzymolysis treatment: add cellulase, pectinase, and alginate lyase to the pretreated Ascophyllum nodosum powder in sequence, and perform enzymolysis at 42°C and pH 6.0 for 24 hours to obtain Ascophyllum nodosum enzymolysis solution; The amount of cellulase, pectinase and alginase lyase added is 3‰ of the total weight of the enzymolysis material; the dosage ratio of cellulase, pectinase and alginase is 1.1:0.9:1.

[0078] Post-processing: filter the Ascophyllum nodosum enzymatic solution to remove the residue, then adjust the filtrate to pH 7.2-7.5 with potassium carbonate, filter, continue to remove the precipitates such as calcium carbonate produced by the acid-base reaction, and ...

Abstract

The invention discloses a seaweed enzymolysis dry-powder added high-column compounded fertilizer. The compounded fertilizer comprises seaweed enzymolysis dry-powder, monoammonium phosphate, ammonium nitrate-phosphorus, ammonium sulfate, Mannheim potassium sulfate, mineral-sourced potassium fulvate and zinc sulfate monohydrate, wherein the seaweed enzymolysis dry-powder is prepared through subjecting ascophyllum nodosum to enzymolysis jointly by cellulase, pectinase and alginate lyase. The compounded fertilizer disclosed by the invention is rich in high-concentration nitrogen-phosphorus-potassium and high-activity seaweed effective ingredients and has compound effects of three kinds of fertilizers, i.e., organic fertilizers, microbial fertilizers and trace-element fertilizers. The inventionfurther discloses a preparation method for the seaweed enzymolysis dry-powder added high-column compounded fertilizer. The seaweed enzymolysis dry-powder is prepared through carrying out joint enzymolysis by employing special combined enzymes, is high in effective active ingredient content and low in salt content and can be applied to strong-base, high-temperature and high-pressure environments,and thus, the range of application of the compounded fertilizer is enlarged; and a preparation process of the high-column compounded fertilizer is optimized, the stability is good, and the prepared product is complete in effect.

Description

technical field [0001] The invention relates to the technical field of high-tower compound fertilizer production, in particular to a formula component of high-tower compound fertilizer added with seaweed enzymolysis dry powder and a preparation process thereof. Background technique [0002] Seaweed is a low-level photosynthetic nutrient plant that grows in the ocean and is the original producer of marine organic matter. In addition to the nutrients that land plants have, seaweed also contains iodine, potassium, magnesium, manganese, and titanium that many land plants cannot match. and other trace elements, as well as seaweed polysaccharides, mannitol, etc. Relevant studies have shown that seaweed has more than 66 active ingredients and active substances, which can provide crops with various nutrients, amino acids, polysaccharides, vitamins, and cytokinins. It can help plants establish a strong root system, improve their absorption and utilization of soil nutrients, water an...
