Embodiment 1

[0036] A preparation method of ascophyllum leaf algae slag organic granular fertilizer, comprising the following steps:

[0037] (1) Preparation of powdery ascophyllum slag

[0038] A Soak the granular Ascophyllum nodosum dregs after the alginate has been extracted, soak them in water, the amount of water added is 30 times the weight of the granular Ascophyllum nodosum residues, then filter the soaked Ascophyllum nodosum dregs, and then perform mechanical crushing Grinding to obtain the crushed Ascophyllum nodosum residue.

[0039] B. Add water to the pulverized Ascophyllum nodosum dregs obtained in step A and mix evenly. The amount of water added is 12 times of the weight of Ascophyllum nodosum to obtain a mixed slurry of Ascophyllum nodosum residue.

[0040] C. Add a compound enzyme preparation to the mixed slurry of Ascophyllum nodosum obtained in step B, stir evenly, and then perform an enzymatic hydrolysis treatment at 45°C for 8 hours to obtain an enzymatic hydrolysis s...

Abstract

The invention discloses a preparation method of Ascophyllum nodosum residue organic granular fertilizer. The Ascophyllum nodosum residue organic granular fertilizer is prepared from the following components: in parts by weight, 200-300 parts of Ascophyllum nodosum residues, 15-30 parts of oyster powder, 2-5 parts of Bacillus subtilis powder, 1.5-3 parts of Phaeophyta nitrogen-fixing bacteria powder, 20-40 parts of potassium dihydrogen phosphate and 10-30 parts of ammonium sulfate. According to the method, waste residues generated by a seaweed processing enterprise are adopted as raw materials,so that the resources are recycled, and the problems of resource waste and a low utilization value of the Ascophyllum nodosum residues are solved; and through the coordination effect among the components, the prepared organic granular fertilizer has a long release cycle of nutrients and a slow release effect on crops, and is capable of loosening and improving soil, increasing organic matter in the soil, improving the disease resistance of the crops and promoting the healthy growth of the crops.

Description

technical field [0001] The invention belongs to the technical field of fertilizer processing, and in particular relates to a method for preparing organic granular fertilizer from ascophyllum leaf residue. Background technique [0002] The ocean area accounts for 71% of the total area of ​​the earth. It is a huge treasure house of resources, providing us with rich biological resources, drug resources and food resources, including rich seaweed resources, including brown algae, red algae, and green algae. . So far, seaweed has shown huge economic value and development potential in the fields and scope of food, medicine, feed, cosmetics, fertilizer, medical dressing and bioenergy. However, in the process of comprehensive processing and utilization of seaweed, due to the limitations of existing technical conditions, many nutrients in seaweed cannot be completely extracted, and seaweed residue still contains rich nutrients, such as betaine, mannitol, Fucoidan, phenolic compounds...
