Problems solved by technology

[0002] The development of existing chemical fertilizers is mostly aimed at slow-release and long-acting effects, while ignoring the promotion of crop growth and stress resistance
Moreover, the existing chemical fertilizers often contain a large amount of industrial raw materials, which will lead to a large amount of residues in the soil after use, making the original fragile soil ecological environment worse, soil compaction and acidification are becoming more and more serious, and the balance of soil structure is broken. The permeability is severely damaged, resulting in frequent occurrence of various diseases caused by soil problems

preparation example Construction

[0035] A second aspect of the present disclosure provides a method for preparing high-tower compound fertilizer, the method comprising the following steps:

[0036]S1. Elevating urea and potassium sulfate to the first-level melting tank at the top of the tower for the first stirring to obtain the first slurry;

[0037] S2. Lift the industrial monoammonium and amino acid chelated calcium to the secondary melting tank at the top of the tower to obtain the first mixture; overflow the first slurry into the secondary melting tank to be mixed with the first mixing material performing a second stirring to obtain a second slurry;

[0038] S3, overflowing the second slurry to the tertiary melting tank for the third stirring, and then adding laver extract to obtain the third slurry;

[0039] S4. Perform high-pressure spray granulation after homogenizing and emulsifying the third slurry.

[0040] According to the second aspect of the present disclosure, in step S1, the conditions of th...

Embodiment 1

[0053] The preparation method of the laver extract in this example is as follows: crush fresh laver, add cellulase and protease to enzymatic hydrolysis for 4 hours to obtain laver enzymatic hydrolyzate; centrifuge and dehydrate the laver enzymatic hydrolyzate treatment to obtain laver enzymatic hydrolysis concentrate, wherein the centrifugation conditions are as follows: the freshly broken laver is enzymolyzed at room temperature for 5 hours, centrifuged at 1600r / min for 5-10min, the sieve aperture is 0.29nm, dehydrated The conditions include: passing the centrifuged enzymatic laver liquid through a nano-molecular sieve membrane, and centrifuging at a speed of 750r / min for 6 minutes; adding an equal mass of vegetable amino acids to the laver enzymatic hydrolysis concentrate to prepare a concentrated laver extract with a dry matter of 60%. Liquid, in which plant-based amino acids are industrially processed high-molecular amino acids imported from Norway.

[0054] Lift 315kg of ...

Embodiment 2

[0057] The preparation method of the high-tower compound fertilizer in this embodiment is the same as in Example 1, the difference is that the laver extract added in the preparation process is 17kg, industrial monoammonium is 255kg, potassium sulfate is 105kg, urea is 306kg, diphosphate Potassium hydrogen is 374kg and amino acid chelated calcium is 17kg.

Abstract

The invention relates to a high-tower compound fertilizer. The high-tower compound fertilizer contains a laver extract, industrial monoammonium, potassium sulfate, urea, monopotassium phosphate and amino acid chelated calcium. The high-tower compound fertilizer provided by the invention is friendly to the soil environment, has long-acting slow release property, can remarkably promote the root growth of crops on one hand, and can provide the stress resistance of the crops on the other hand.

Description

technical field [0001] The application relates to the field of special new fertilizers, in particular to a high-tower compound fertilizer and its preparation process. Background technique [0002] Most of the existing chemical fertilizers are developed for the purpose of slow-release and long-acting effects, while ignoring the promotion of crop growth and stress resistance. Moreover, the existing chemical fertilizers often contain a large amount of industrial raw materials, which will lead to a large amount of residues in the soil after use, making the original fragile soil ecological environment worse, soil compaction and acidification are becoming more and more serious, and the balance of soil structure is broken. The permeability is severely damaged, resulting in frequent occurrence of various diseases caused by soil problems. [0003] Therefore, there is an urgent need for a new compound fertilizer that is friendly to the soil environment and can promote the growth and ...
