The invention provides a trace element adding method for promoting the growth of leeches and aims to provide a breeding method capable of obviously increasing the mass of leech bodies, enhancing the immunity and increasing economic benefits on the basis of an existing leech breeding technology. Compared with existing bred leeches, the leeches bred by means of the method have the advantages that the mass is increased by about 30.02%, and the death rate is reduced by 25%. According to incomplete statistics, compared with existing leech breeding, the method has the advantages that the dry weightof the leeches bred by means of the method can be increased by about 40.03 kg per mu, and the economic benefits are increased by about 40,000 yuan per mu according to the current market price of 1,000yuan/kg. 本发明提供一种促进蚂蟥生长的微量元素添加方法。本发明目的在现有蚂蟥养殖技术基础上提供一种能显著提高蚂蟥体质量，增强免疫力，增加经济效益的养殖方法。采用本发明方法养殖蚂蟥，可比现有养殖蚂蟥体质量提高约30.02％，死亡率降低25％。与现有蚂蟥养殖相比，不完全统计，采用本发明方法养殖蚂蟥每亩可增加蚂蟥干重约40.03公斤，按照目前市场价1000元/kg计，每亩增加经济效益约4.00万元。
