Problems solved by technology

Song Dalu proposed the method of cultivating earthworms in soil ditches ("Southwest Militia", 1997, 36), but it could not solve the problem of the decrease in the purity of earthworm strains caused by the hybridization of medicinal earthworm varieties with other earthworm varieties, and at the same time, it could not guarantee the capture efficiency of earthworms
The defects of traditional earthworm breeding methods are mainly reflected in: (1) the purity of earthworm species (especially medicinal earthworms) cannot be guaranteed; (2) the output of earthworm culture varies greatly, such as the traditional red earthworm (Daping No. 2, etc.) has a higher yield However, the medicinal value is relatively low, and the yield and quality of earthworms cannot be guaranteed by the pot culture method and the cage rearing method; (3) The traditional method of earthworm capture is inefficient, time-consuming and laborious; (4) Earthworms (especially medicinal earthworms) It is very sensitive to environmental factors. The traditional existing breeding methods are separated from the natural growth environment of earthworms. There are too many factors affecting the growth of earthworms that are uncontrollable, and there are disadvantages such as low earthworm yield and high mortality.

Embodiment 1

[0112] 50kg of soil and 6kg of earthworm breeding material are rotted and stirred to prepare the mixture, and watered to keep the humidity of the soil at 65%, and packed into a mesh bag. The size of the mesh bag is 50cm*50cm*80cm, and the mesh size in the mesh bag is 50 mesh.

[0113] Dig ditches and ridges in the facility farmland, and the soil humidity in the facility farmland is 50%. The distance between ridges is 4m, and 4 inter-ridge furrows are opened per mu. The depth of the inter-ridge furrows is 60cm, and the width of the inter-ridge furrows is 0.65m. A mesh bag is placed in every meter of ditch between the ridges, the seal of the mesh bag is knotted, and the top of the mesh bag is exposed outside the ditch between the ridges and is 10 cm above the farmland level.

[0114] Put 1.2kg earthworm seedlings into each net bag again, add 0.55L water again, allow earthworms to moisten and facilitate it to drill into the soil quickly, then cover the net bag with a shading objec...

Embodiment 2

[0117] 50kg of soil and 4.5kg of earthworm breeding material were rotted and stirred to prepare the mixture, watered and kept moist, so that the humidity of the soil was controlled at 60%, and packed into a mesh bag. The size of the mesh bag is 50cm*50cm*80cm, and the mesh size in the mesh bag is 60 mesh.

[0118] Ditching and ridges are made in the farmland of the facility greenhouse, and the humidity of the soil in the farmland is 45%. The distance between the ridges is 4m, and 4 inter-ridge furrows are opened per mu. The depth of the inter-ridge furrows is 55cm, and the width of the inter-ridge furrows is 0.7m. A mesh bag is placed in every meter of ditch between the ridges, the seal of the mesh bag is knotted, and the top of the mesh bag is exposed outside the ditch between the ridges and is 10 cm above the farmland level.

[0119] Put 1.1kg earthworm seedlings into each mesh bag again, add 0.50L water again, let the earthworms moisten and facilitate it to drill into the ...

Embodiment 3

[0124] The earthworms obtained in Example 1 are classified, weighed, and the interval ratio after collection, and it is found that each earthworm with more than 6 grams accounts for 14%, and each earthworm with 5-6 grams accounts for 23%, and each 4-5 grams Earthworms accounted for 37%, each 3-4 grams of earthworms accounted for 16%, each 2-3 grams of earthworms accounted for 10%, the specific results are shown in Table 1. Among them, more than 90% meet the harvesting requirement of medicinal earthworms ≥ 2.5 g / piece.

Abstract

The invention provides a method for industrialized cultivation of earthworms in a facility greenhouse. Ditches and ridges are dug in the farmland of the facility greenhouse, and at least one net bag is arranged in the ditch between the ridges, and the mixture of soil and earthworm breeding material is installed in the net bag , and then put the earthworm seedlings into the net bag and put in the earthworm breeding material for cultivation. The industrial cultivation method of earthworms in a facility greenhouse provided by the invention has a high yield in the farmland of a facility greenhouse, can be harvested 4-5 times / year, has high benefit, is convenient for harvesting, and has high purity (earthworms cannot naturally hybridize. ), low earthworm escape rate and other advantages.

Description

technical field [0001] The invention belongs to the technical field of agricultural breeding, and relates to a factory-like breeding method for earthworms in facility greenhouses. Background technique [0002] Earthworms, also known as earthworms, are terrestrial invertebrates of the phylum Oligochaeta. At present, there are more than 3,000 species of earthworms in the world, and more than 200 species in my country. Among them, earthworms, as the giant worms, include Pheretima aspergilium (E.Perrier), Pheretima vulgaris Chen, Pheretimaguil-lelmi (Michaelsen), Pheretima pectinifera Michalsen, etc. Variety. [0003] Earthworms are rich in nutrition and high in artificial breeding, and can be used as high-protein food and feed. At the same time, earthworms are cold in nature and salty in taste, can clear away heat and calm convulsions, dredge collaterals, relieve asthma, and diuresis; they have the effects of lowering blood pressure, relieving cough, calming and antipyretic,...
