Description
Technical Field
The invention belongs to the technical field of agricultural cultivation, and relates to a method for industrially cultivating earthworms in a facility greenhouse.
Background
Earthworm is also known as earthworm, a terrestrial invertebrate of the oligochaeta of Annelida. At present, more than 3000 kinds of earthworms exist in the world, and more than 200 kinds of earthworms exist in China. The earthworms include, as lumbricus, Pheretima aspergillum (E.Perrier), Pheretima vulgaris Chen, Pheretima giganteum-leimi (Michaelsen), and Pheretima pectificans pictoria Michaelsen.
The earthworm is rich in nutrition, has high artificial breeding yield, and can be used as high-protein food and feed. Meanwhile, the earthworms are cold in nature and salty in taste, and can clear heat and relieve convulsion, dredge collaterals, relieve asthma and promote urination; has effects in lowering blood pressure, relieving cough, tranquilizing mind, relieving fever, resisting cancer, and enhancing immunity; it can be used for treating hyperpyrexia, unconsciousness, epilepsy, dermatoses, cough and asthma due to lung heat, burn, scald, bronchial asthma, and hypertension. At present, the application of the earthworms in clinic is accepted by extensive researchers, and the development and research of the earthworms as medicines can obtain great economic value and benefit all mankind.
Furthermore, earthworms can decompose organic substances by taking, digesting, excreting (earthworm feces), excreting (mucus), digging holes and other activities, create good conditions for the growth and reproduction of soil microorganisms, play a special role in material circulation, biodiversity and other aspects, contribute to the material circulation and energy transfer in the soil process, are one of soil invertebrate groups (mainly earthworms, mites and ants) which have important influence on a plurality of processes determining the soil fertility, and are called "ecosystem engineers". Earthworms are currently used in many countries to treat domestic waste, organic waste and to purify sewage.
The traditional earthworm breeding method comprises a pot breeding method, a box basket breeding method, a pond breeding method, an earth furrow breeding method, a garbage breeding method, a ground trough breeding method, a rack type breeding method and the like, and the earthworm breeding in a greenhouse (especially for medicinal earthworms) is not reported. Songdahu proposed a method for breeding earthworms in the earth ditches (civil soldiers in the southwest, 1997,36), but could not solve the problem of purity reduction of the earthworms caused by hybridization of medicinal earthworm species and other earthworm species, and could not guarantee the earthworm capture efficiency. The defects of the traditional earthworm breeding method are mainly reflected in that: (1) the purity of earthworm species (especially medicinal earthworms) cannot be guaranteed; (2) the earthworm breeding yield difference is large, for example, the traditional red earthworms (Daping No. two and the like) have high yield but relatively low medicinal value, and the yield and the quality of the earthworms cannot be guaranteed by adopting a basin breeding method and a box basket breeding method; (3) the traditional method has low earthworm capture efficiency, wastes time and labor; and (4) earthworms (especially medicinal earthworms) are very sensitive to environmental factors, the traditional culture method is separated from the natural growth environment of the earthworms, the uncontrollable growth of the earthworms has too many influencing factors, and the defects of low earthworm yield, high death rate and the like exist.
