[0053] (1) Preparation of seaweed residue
[0054] A. Crushing and grinding the seaweed, adding water to the crushed seaweed slurry and mixing evenly, the amount of water added is 10 times the weight of the seaweed;
[0055] B. Add a compound enzyme preparation to the mixed slurry obtained in step A, stir evenly and enzymatically treat it at 40° C. for 4 hours, and the dosage of the compound enzyme preparation is 2% of the weight of the seaweed;
[0056] C, centrifuging the enzymolysis solution obtained in step B, and removing the supernatant to obtain the residue;
[0057] D, mixing and fermenting the residue obtained in step C with the biological starter, the quality of the biological starter is 0.5% of the residue quality;
[0058] Aerobic fermentation: when the pile temperature rises to 50°C, turn the pile in time to increase air permeability and lose water, and ferment for 15 days until the temperature in the pile no longer rises; anaerobic fermentation: after aerobic fe...

Abstract
The invention discloses a preparation method of a seaweed biological composite fertilizer. The preparation method of the seaweed biological composite fertilizer comprises the steps of preparing seaweed slag; preparing bacillus thuringiensis powder; and uniformly mixing the seaweed slag with the bacillus thuringiensis powder to obtain the seaweed biological composite fertilizer. The seaweed biological composite fertilizer comprises 300-600 parts by weight of the seaweed slag and 50-200 parts by weight of the bacillus thuringiensis powder. The prepared seaweed biological composite fertilizer ishigh in content of toxalbumin and high in Chinese chive maggot killing activity, does not have sick insect eggs, and has good effect of preventing and controlling Chinese chive maggots, and the application amount of chemical pesticides is reduced effectively. The seaweed biological composite fertilizer contains high content of active substances, is high in nutrient, can be decomposed by microorganisms in soil and can be absorbed and utilized by fragrant-flowered garlics, meanwhile, soil can be loosened, rooting and growth of the fragrant-flowered garlics can be promoted remarkably, nutrition required for growth is provided, the quality of the fragrant-flowered garlics is improved, the seaweed biological composite fertilizer is safe and healthful, environmental protection and zero pollutionis realized, and the seaweed biological composite fertilizer has quite good development prospect.
Description
technical field [0001] The invention relates to the technical field of fertilizer processing, in particular to a preparation method of seaweed biological compound fertilizer. Background technique [0002] my country has a long coastline, a large area of shallow sea, and rich marine resources. There are about 800 species of seaweed that have been recorded, among which large species such as brown algae, red algae, green algae and a small amount of blue algae are economically valuable. So far, seaweed has shown great development potential and economic value in the fields and scope of food, marine medicine, animal feed, organic fertilizer, cosmetics and bioenergy. During the processing and utilization of seaweed, especially after extracting mannitol, alginate, iodine and other substances, due to the limitation of the existing process conditions, these components cannot be completely extracted, and the remaining part remains in the waste seaweed residue . Therefore, these sea...
