介绍水蛭放养的季节选择:

　　Introduce leeches grazing season of choice:

　　月平均气温南方14℃，北方13℃，均可视为可以放养水蛭的季节，最理想的是水温稳定在18℃以上的季节。

　　14 ℃ month average temperature in the south, the north 13 ℃, all can as a can of grazing leeches season, the ideal is the season of water temperature stability above 18 ℃.

　　For as far as possible to extend the time of leeches growth raised, satisfy the requirement of temperature and the basic conditions, strive for early delivery, and management, in the delivery of the skills to see results.

　　Middle of the south in early April or put in the breeding, to 19 months late ignore the mid-november leeches before hibernation, the range of feeding time can reach 7 months, if put in the time delay, the breeding of leech time will be extended;

　　北方如果在5月份进行放养，到10月份水蛭进入冬眠前，也有5个月的饲养时间，要延长当年的饲养时间；

　　If kept in May, north to the front of the leeches into hibernation in October, also have five months of feeding time, to extend the breeding time;

　　Is the best way to solve the premise of seedlings, take from numerous ways to solve the source of goods leeches miao, if artificial breeding methods to improve the temperature, break the leech hibernate behaviour, needs high technology and capital investment.
