目前,适于人工养殖并且已获成功的水蚯蚓有:苏氏尾鳃蚓、霍甫水丝蚓。这些水蚯蚓生活在淹水情况下的水田和水沟边,能长期生活在缺氧的有水层的土层中,如生活在水田的尾鳃蚓,在淹水情况下,能在耕作层活动。在稻田里放养水蚯蚓,能大大促进水稻的生长和发育,使水稻产量增加一倍,据广东省博罗县农科所试验,放养苏氏尾鳃蚓 At present, the earthworms that are suitable for artificial breeding and have been successful are the gill worms and the earthworms Hook. These water earthworms live in paddy fields and ditches under flooded conditions and can live long-term in hypoxic aquiferous soil layers, such as the gill epidermis living in the paddy fields. Under flooding conditions, activity. The stocking of water earthworms in the rice fields can greatly promote the growth and development of rice and double the output of rice. According to the experiment by Boluo County, Guangdong Province,
