Abstract

The invention discloses a leech high-density stereoscopic cultivation method. The leech high-density stereoscopic cultivation method includes the following steps: arranging cultivation net cages, arranging cultivation media, putting in seedlings, putting in feeds, managing water quality and carrying out inter-cultivation outside the net cages. According to the leech high-density stereoscopic cultivation method, the cultivation density and the survival rate of leeches are greatly improved, and the yield is improved. By means of the existing leech cultivating technology, the dried leech products per mu is about 40kg, after the leech high-density stereoscopic cultivation method is adopted, the dried leech products per mu can reach about 50kg, and the yield is improved by 25%. The feeds (apple snails and field snails) and the leeches are inter-cultivated, the use rate of soil source is improved, meanwhile, lemna minor or water hyacinth planted on the water surface can meet the growth requirements of the apple snails and the field snails, two purposes are achieved, the use rate of the feeds is improved, the production cost is saved, and the economic benefits are improved.

Description

technical field [0001] The invention belongs to the technical field of leech cultivation, and in particular relates to a method for high-density three-dimensional cultivation of leeches. Background technique [0002] Leech, commonly known as leeches, is the collective name of the animal phylum Hirudophylum in the upper link of animal classification. It grows and reproduces in inland freshwater waters. It is a traditional special medicinal aquatic animal in my country. After its dried products are processed, they are used as medicine in traditional Chinese medicine. , blood stasis, amenorrhea, bruises and other effects, especially for the preparation of Chinese patent medicines for the treatment of cardiovascular and cerebrovascular diseases. In recent years, with the continuous deepening and development of medical research on leeches, the medicinal value has been gradually reflected. It has become one of the most popular Chinese herbal medicines in the world, and has broad app...
