The invention relates to the technical field of agricultural microorganisms, and discloses a preparation method and application of high-concentration
spore liquid of
Ceriporia lacerata. The preparation method comprises the following steps: culturing hyphae by seeds, and culturing in a
fermentation tank to form
fermentation tank mycelia; upon completion of
fermentation, pretreating
fermentation broth, adding a filter aid, uniformly stirring to obtain pretreated fermentation liquor, then feeding the pretreated fermentation liquor into a plate-and-frame
filter press for filtering, discarding filtrate,
drying and dehydrating an obtained
filter cake to obtain
solid mycelia, and then adding a
spore protective agent, uniformly stirring and mixing to obtain a
mycelium diluent, and finally subpackaging and hermetically storing the
mycelium diluent to obtain the high-concentration
spore liquid of the
Ceriporia lacerata, which is convenient to store, capable of reducing the storage and
transportation cost and more beneficial to field spraying and use. When mycelia are obtained from fermentation liquor, a filter aid is added,
solid mycelia are obtained through
drying and
dehydration, and
mycelium autolysis caused by excessive accumulation of the mycelia can be avoided.
