The invention mainly relates to the technical field of planting and discloses a special substrate for
seedling of celeries. The special substrate is prepared from the following raw materials: straws, sheep
manure, pig
manure, fallen leaves,
saw dust,
bagasse, waste vegetable leaves,
sericulture leftovers,
plant ash,
vermiculite,
perlite, EM
bacteria and prolonium
iodide. The special substrate is balanced in
nutrition and is favorable for absorption of seeds, so that the
celery seeds germinate 2-3 days in advance, the
germination rate is 84.7%, and the planting efficiency of the celeries is obviously improved; the straws, the sheep
manure, the pig manure, the fallen leaves, the
saw dust and the
bagasse are smashed and then are transplanted into the EM
bacteria for high-temperature
fermentation, so that the multiplication of thalli is promoted, and the
fermentation time is shortened; the waste vegetable leaves, the
sericulture leftovers and the
plant ash are added, and then the temperature is lowered for
continuous fermentation, so that the accumulation of
extracellular metabolites is promoted, the absorption of the seeds is facilitated, embryos are stimulated to grow, and the germinating time of the seeds is shortened.
