Method for cultivating earthworms

Abstract

The invention provides a method for cultivating earthworms. The method comprises the steps that first, a base box body is sequentially filled with river stones, gravel and silver sand, an earthworm cultivation box is placed on the base box body, organic waste mixtures are arranged in the earthworm cultivation box, then earthworm seedlings are put into the earthworm cultivation box, after the earthworms are cultivated for 30 days, organic waste mixtures are continuously added into the earthworm cultivation box until the earthworm cultivation box is filled with the organic waste mixtures; earthworm cultivation boxes are continuously placed on the earthworm cultivation box filled with the organic waste mixtures, after the earthworm cultivation box at the top layer is filled with the organic waste mixtures, the earthworm cultivation box at the bottom layer is drawn out, and the earthworm cultivation box is placed back to the top layer after earthworm cast in the earthworm cultivation box is cleaned away to achieve circulation cultivation. The method for cultivating the earthworms has the advantages that the facts that earthworms are bred from generation to generation, are inbred and are in variety degeneration are avoided, and breed conservation and reproduction of the earthworms can be better achieved. Adult earthworms are harvested conveniently, the living and incubation environment of the earthworms is not damaged, the incubation rate is guaranteed, and the method is suitable for earthworm industrial large-scale cultivation.

Description

technical field

[0001] The invention relates to a method for cultivating earthworms. Background technique

[0002] Earthworms are annelids that grow in the soil. They are rich in protein and can be used as medicine. At present, earthworms are generally cultivated in earthworm breeding boxes. When harvesting, earthworms and vermicompost need to be taken out together and then separated, thus seriously destroying the living environment of earthworms and affecting the hatching of earthworm cocoons. Many young earthworms and earthworm cocoons are difficult to separate, resulting in low earthworm output; and earthworms are often fed together from generation to generation, and reproduce in modern times, resulting in racial degradation, which is not conducive to the conservation and reproduction of earthworms.

[0029] Embodiment 1 (breeding with earthworms)

[0030] 1.1. Adopt a three-dimensional multi-layered earthworm breeding bed composed of a base box body 1 with a height of 30 cm and a bottom surface with drainage holes 101, and 4 earthworm breeding boxes 2 with a height of 20 cm stacked on the base box body 1. The bottom of the culture box 2 has a sieve hole with a diameter of 0.5cm; first fill the base box with river stones, crushed stones and fine sand successively and fill up to form a river stone layer, a crushed stone layer and a fine sand layer. The heights of the stone layer and the fine sand layer are 15cm, 10cm, and 5cm respectively, among which, the diameter of the river stone is 4cm-5cm, and the diameter of the crushed stone is 2cm-3cm;
