+++ Abstract +++
This paper reviews the history of vermiculture, indicating it is an
important component of macro-agriculture. Earthworms seem to be the
missing link of ecological agriculture in China.
Earthworms can treat large amounts of organic garbage, livestock
manure and poultry droppings and turn them into premium organic
fertilizers, and thus could greatly improve the ecological environment
in rural areas to restore the fertility of the soil because humus only
exists in earthworm feces and castings compared with other
fertilizers. Earthworms can supply quality animal protein for feed and
even for human consumption, and offer the best raw materials for
biochemical and pharmaceutical industries. As industries and
agriculture develop and urban construction is booming, the discharge
of wastewater and sewage soars and wastewater treatment plants are set
up everywhere around cities; stabilizing the sludge presents a big
challenge and earthworms could play an important role in facing this
challenge. Vermiculture should be oriented to stabilize sludge and
organic wastes in circulation economy, for it is an approach to
sustainable agriculture and a measure in promoting organic farming so
as to break technical barriers of production in international trade.
It should be supported by policies under the guidance of scientific
development viewpoint and be put into whole circulation economy as a
means of protecting the environment, maintaining ecological balance,
and fully utilizing resources. However, it should be combined with
other technologies such as EC (electro-coagulation), EH (energized
hydrolyser), and especially EM (effective microorganisms). We should
promote courtyard earthworm composting as well as large-scale
vermiculture, which should be mechanized and automated.
