Seaweed fertilizers is an efficient,green
and new type of fertilizer.The main raw
materials,which consist of plentiful
nutriments and some speical bio-chemical
components,are economic algae in the sea.In
addition to the nutriments of land
plants,the fertilizer also has some
beneficial elements and microelements such
as iodine,K,Mg,Mn and Ti.The all exist in
algae as organic matters so they are not
easily to be oxidized.That means that they
can be absorbed and used more efficient than
inorganic elements by plants.The fertilizer
has plenty of active materials,such as
seaweed amylose,poly-
hydroxybenzene,phytohormone.These active
materials take part in the transport of
organic and inorganic matters in
plants,enhance the absorption of nutriments
by plants,improve the photosynthesis of
plants,enhance the growth of root
system,meliorate cell division and
elongation,at the sames time.The crude
amylose can enhance gas permeability of soil
and conserve soil water.In this way,the
fertilizer can avoid forming stiff
sil,modulate soil air and conserve soil
moisture.
