Earthworm screening plant

Technical Field

The utility model relates to an earthworm screening plant belongs to earthworm cultivation technical field.

Background

The Lumbricus contains high protein 50-65% of dry weight, and 18-20 kinds of amino acids, wherein more than 10 kinds are necessary for fowl and livestock. Therefore, the earthworm is an animal protein additive feed, and has obvious effect of improving the yield of poultry, livestock and fish. Earthworm contains earthworm extract, various amino acids, vitamins and the like, has the functions of relieving fever, calming, relieving asthma, reducing blood pressure, promoting urination and the like, and is taken as a medicine from old times.

Earthworms have great capability of swallowing soil and organic substances, so that the earthworms are utilized to treat urban organic garbage at present, protect the environment, prevent pollution, turn harm into benefit and inhibit public nuisance. The countries build factories for breeding earthworms, breed earthworms, treat waste materials and produce organic fertilizers. The earthworms have the capacity of gathering some heavy metals (cadmium, lead, zinc and the like) in the soil, and can collect the earthworms to treat the soil polluted by the heavy metals, thereby achieving the purpose of reducing pollution. The processed earthworms can be used for making food, and the earthworms are used for making biscuits, bread and the like abroad.

Because the earthworms have multiple purposes and benefits, the earthworms are promoted to be bred into hot topics, and the earthworm breeding by using the urban organic garbage or the sludge can also play a role in protecting the environment. Currently, earthworm breeding is mainly realized through a box-type breeding bed, a pool-type breeding bed and a groove-type breeding bed. The earthworms can produce wormcast in the cultivation process, and after the cultivation is mature, the earthworms and the wormcast need to be separated to obtain the earthworms.

There is currently no good screening device.
