The invention relates to the technical field of ecological restoration, specifically to a preparation method for
peat moss propagules used for peatland restoration. The preparation method comprises the following steps: collecting
peat moss with capsula from a field, carrying out cleaning, separating
peat moss capsula from plants, disinfecting the capsula with ethyl
alcohol, carrying out crushing so as to prepare a
spore suspension used as sexual peat moss propagules,
cutting the plants into segments, carrying out disinfection with
sodium hypochlorite so as to obtain disinfected
plant segmentsused as asexual peat moss propagules, mixing the peat moss propagules with a
liquid culture medium and
sodium alginate under stirring so as to obtain a uniform
viscous liquid, then dropwise adding theviscous liquid into a
calcium chloride solution, and carrying out hardening treatment so as to form gel particles of the peat moss propagules. The above-mentioned particles are spread into a to-be-restored peatland, and after field planting of the particles, reintroduction of
vegetation in the process of peatland restoration is completed. The preparation method provided by the invention achievesthe following advantages:
nutrition and protection are supplied for the peat moss propagules in a field environment by utilization of a gel; the
survival rate of the peat moss propagules is improved;the peat moss propagules have strong adaptability and can be extensively applied to various degraded peatlands; meanwhile, the used gel is easy to be degraded, and has little influence on the peatland.
