The invention relates to a
pheretima bombycis farm, and belongs to the technical field of
earthworm breeding. The problem that
earthworm suffocation death is caused by cross
contamination of pathogenic microorganisms and unsmooth drainage due to mixing of functional areas of a traditional farm is solved. The
layout of the farm is specifically as follows: a
raw material pretreatment and
storage area provided with a
fermentation tank is arranged in the upwind direction of
a site entrance; a core breeding
production area is arranged in the center of the field, the interior of the core breeding
production area is divided into an
earthworm breeding area, a breeding area and a fattening area according to breeding stages, and mechanical channels are arranged in the areas and are of a
ridge type structure; arranging an annular
drainage ditch along the boundary of the field, and communicating the furrow with the annular
drainage ditch by gradient; a finished product treatment and
storage area containing an airing field is arranged in the downwind direction of the field exit; an isolation belt is arranged on the periphery, a management and auxiliary area containing a tool room is arranged at an entrance, and a
feces treatment area containing a
sedimentation tank is arranged in the downwind direction; the hardened main road is connected with all the functional areas, and the
branch is communicated with the breeding district. According to the scheme,
pollution source isolation and efficient drainage are achieved, and the method is mainly used for improving the earthworm
survival rate and breeding benefits.
