The invention discloses a composite seaweed
fertilizer and a preparation method thereof. The composite seaweed
fertilizer comprises raw materials and auxiliary materials. The
fertilizer is prepared from the following
raw material components in parts by weight: 7-9 parts of seaweed, 5-7 parts of
algae residues, 6-8 parts of microalgae residues, 4-6 parts of
ascophyllum nodosum, 1-3 parts of
Ecklonia kurome, 4-6 parts of
kelp, 3-5 parts of gulfweed, 2-4 parts of Chewangzao, 2-4 parts of desert
algae, 2-4 parts of Rhodomelaceae, 3-5 parts of
fucus, 1-3 parts of enteromorpha, 1-3 parts of
Ulva lactuca, 3-5 parts of Kappaphycus, 3-5 parts of
brown algae, 2-4 parts of citrus peel residues, 1-3 parts of
zeolite, 4-6 parts of shells and 4-6 parts of
urea. According to the composite seaweed fertilizer and the preparation method thereof, compared with an
organic fertilizer, thec omposite seaweed fertilizer use
algae as main
raw material, the cost can be effectively reduced, the environment optimization effect can be achieved, the manufacturing method changes a traditional
evaporation and concentration process,
energy consumption is reduced, and through the processes of
drying, cooling, reacting, fermenting and the like, the composite seaweed fertilizer has the advantages that various nutrients in the algae are fully used, the cost is conveniently reduced, the application range of the seaweed fertilizer is widened, the environment is effectively protected and the like.
