The invention belongs to the technical field of producing and
processing of agricultural industries, and relates to an
earthworm breeding method through a photovoltaic facility (a photovoltaic multi-span
greenhouse). The
earthworm breeding method comprises the following steps: preparing a field, preparing a feed, preparing an appliance,
stocking earthworms, managing feeding and harvesting the earthworms. According to the invention, agricultural wastes,
landscaping wastes and
feces of
livestock and poultries are fermented in a mixed manner and used as an
earthworm feeding substrate; therefore, the problems of resource waste and environmental
pollution are solved; furthermore, an abundant and reasonable carbon-to-
nitrogen ratio and the like in the feed can be ensured; the
production rate and the growth quality of the earthworms are increased; the feeding substrate is sufficiently fermented by adding EM bacterial solution in a composting process; therefore, breeding of harmful
bacteria can be effectively inhibited; the number of beneficial bacterial colonies is increased; the
disease resistance of the earthworms is enhanced; the earthworms grow rapidly and are high in reproductive rate; the output rate of the earthworms is about 9.2 kg / cm; a
seedling bed is arranged over an earthworm breeding
bed in a bridging manner; breeding and planting are combined in a three-dimensional manner; the space is sufficiently utilized; the comprehensive cost is low; by utilizing a
solar energy photoelectric
integrated technology, a proper growth environment is provided for the earthworms and crops through an automatic
intelligent control system, and therefore,
energy consumption can be saved.
