The invention relates to the field of
plant cultivation media, and particularly provides a degradable foam composition for
seedling raising or flower arrangement. The degradable foam composition for
seedling raising or flower arrangement is prepared from the following raw materials:
phenol and polyformaldehyde in a
mole ratio of 1:(1.4-2.5), water (24mL for every mole of
phenol),
urea (accounting for 10-25 wt% of the
phenol), pulp board (accounting for 6-15 wt% of the phenol),
starch (accounting for 6-15 wt% of the phenol), and 10 wt%
polyvinyl alcohol (accounting for 2-15 wt% of the phenol). The invention also provides a preparation method and application of the degradable foam composition for
seedling raising or flower arrangement. The
reaction speed of the preparation method is greatly higher than that of the traditional method, and no
wastewater is generated in the whole process. The free
formaldehyde content and
free phenol content of the prepared product are lower than the
national standard, so the product is completely harmless; and the seedling raising container or flower mud prepared from the degradable foam composition is suitable for demands of plants for physical properties of the
nutrient and medium.
