Method for cultivating earthworms for experiment

Abstract

The invention discloses a method for cultivating earthworms for experiment, belonging to the technical field of cultivating special animals. The method comprises the following steps of: paving a layer of sponge in a cultivating box, spraying water until the sponge is wet; putting the sponge layer into a cultivating bed which is paved by soil and bait into layers according to different proportions, wherein the height of the cultivating bed is 18-25cm; when cultivating pheretima guillelmi, controlling pH of the soil within 6-7, placing the bait which accounts for 0.5-1% by weight of the soil at 1-2cm of the surface of the soil, controlling water content of the cultivating bed within 50-70%, putting the earthworms in the cultivating bed; when cultivating eisenia foetida, controlling pH of the soil within 6-7, placing the bait which accounts for 1-2% by weight of the soil on the top of the soil, controlling water content of the cultivating bed within 40-80%, wherein the cultivation is carried out under the condition of illumination. The method is simple in operation, and capable of effectively improving survival and activity of the earthworms, and the conditions are easy to control.

Description

technical field [0001] The invention relates to a method for cultivating earthworms, in particular to a method for cultivating earthworms for experiments. Background technique [0002] Earthworm is a hermaphroditic, heterogeneous scavenging soil animal. It has the physiological characteristics of wide appetite, large food intake and the ability to secrete various enzymes in the body to decompose protein, fat, carbohydrates and cellulose. Organic waste is decomposed and transformed through the mechanical friction of the gizzard and the biochemical action in the intestinal tract. Earthworms are rich in edible and medicinal value. In the United States and Japan, refined earthworms have been used to bake biscuits, bread and meat substitutes (Xu Bin et al., 2010). The Chinese medicinal name of earthworms is Dilong, which can treat asthma, jaundice, typhoid fever and gum ulcers (Xu Bin et al., 2010). [0003] The test methods for acute toxicity of earthworms are included in the...

Problems solved by technology

At present, there are not many studies on the breeding methods of experimental earthworms.

In the literature related to earthworm breeding methods, the breeding method introduced in "Technical Key Points of Earthworm Culture" ("Jiangxi Animal Husbandry and Veterinary Journal", 2004) is not strictly controlled, which may easily cause obvious individual differences among earthworms and poor parallelism, which will affect the experimental results. make an impact

In addition, in "Research on the Laboratory Feeding Method of Earthworms" ("Food Research and Development" Magazine, 2010), it introduced the method of feeding in boxes and baskets and making fermented feed at the same time. The method is complicated to operate, and the process of fermented feed will also affect the Influenced by the laboratory environment
