Embodiment 1

[0039]

[0040] The raw material seaweed extract obtaining method:

[0041] 1) Mechanically grind the fresh seaweed into a slurry mixture to achieve physical wall breaking;

[0042] 2) Add 3 kg of cellulase to the 997 kg slurry mixture obtained in step 1), and perform enzymatic hydrolysis at 40°C for 3 hours under stirring, so as to achieve enzymatic hydrolysis and wall breaking;

[0043] 3) Add 2 kg of alginate lyase to 1,000 kg of enzymatic hydrolysis solution obtained in step 2), and perform enzymatic hydrolysis at 50°C for 4 hours under stirring, so as to realize the conversion of alginate from large molecules to small molecules;

[0044] 4) The mixture obtained in step 3) is cooled to normal temperature, centrifuged at 3000-4000 rpm for 30 minutes, and then the supernatant is spray-dried, or the suspension is directly spray-dried at a high temperature of 150-175°C without centrifugation.

Abstract

The invention provides an algin high-power compound fertilizer which is characterized by comprising the following components in percentage by weight: 0.5-5% of seaweed extract, 0.075-0.75% of alginic acid, 0.005-0.05% of seaweed polysaccharide, 5-40% of urea, 5-20% of ammonium sulfate, 5-40% of ammonium dihydrogen phosphate, 5-50% of potassium sulfate, 5-20% of calcium-magnesium mineral powder and 1-2% of trace element. The invention also provides a preparation method of the algin high-power compound fertilizer. The algin high-power compound fertilizer provided by the invention can meet the needs of the crop on various nutrients, and also has the characteristics of high technological content, uniform nutrient, good water solubility, wide application range and the like.

Description

technical field [0001] The invention belongs to the field of compound fertilizers. Specifically, the present invention relates to an alginous high-tower compound fertilizer and a preparation method thereof. Background technique [0002] Fertilizer is an indispensable means of production in agriculture and an important means to ensure agricultural production. In my country, a big country that uses 7% of the world's arable land to feed 22% of the world's population, the application of chemical fertilizers is particularly important. However, the current chemical fertilizer industry in my country has problems such as flooding the market with inferior fertilizers, unreasonable industrial structure, and mostly relying on imports of high-quality fertilizers. Therefore, the development of chemical fertilizers still cannot meet the needs of agricultural development. [0003] At present, the field has gradually begun to use high-tower granulation technology to produce high-quality c...
