High-yield density cultivating technology for leeches

The invention provides a high-yield density cultivating technology for leeches and aims to provide a leech cultivating density with higher mu yield than the current mu yield and good economic benefit on the basis of the conventional cultivating technology. When the cultivating density disclosed by the invention is selected, the mu yield can be increased by 22.7 percent compared with the conventional cultivating density. On the premise of not increasing the intensive cultivating area of leeches, the economic benefit of leech cultivating is increased. By adopting the technology, the mu yield of a dry leech product can be increased by about 40 kilograms, and the economic benefit per mu is increased by about 28-32 thousand yuan counted by the current price on market of 800 yuan/kilogram.
