How to keep water well

Leech is commonly known as leech, and its dried body is a valuable medicine. Modern medicine is mainly used for the extraction of hirudin and has a high medical value. The main varieties of medicine leeches are: Japanese doctor's ampoules, broiled golden ray rakes, wide-body gold ray lice, and burdock roots. Among them, the wide-body gold wire has the largest body shape and gentle temperament, and is the best breed for artificial breeding. The leeches have a strong vitality and they have traces in areas where the environment is suitable. In our country, they are mainly produced in lakes and river valleys between 32-38 degrees north latitude. This area is most suitable for the growth of otters. The water feed is miscellaneous and grows fast. It can be cultured if it is reformed in a small fish pond. Some low-altitude farmland and lakeshore beaches that meet the requirements can also be cultivated. Artificially excavated leeches have lower requirements for ponds than fish ponds and less earth excavation. It is very important to choose the site for the first time. It is necessary to choose a sheltered, sun-drenched, convenient drainage and irrigation facility. The pool is 1.8 meters high and the water depth is 1 meter. The area should be determined according to the amount of feeding. Generally, 6 to 10 thousand larvae can be stocked per mu of water. The pool is located diagonally at the inlet and outlet. In order to facilitate the habitat and spawning of otters, some irregular stones or twigs can be placed at the bottom of the cistern, and 5 to 8 soil platforms above the level of 20 cm should be built in the pool, about 1 meter per platform. The pool pool should also be set aside to escape the ditch, made of bricks, with a ditch width of 12 cm and a height of 8 cm. When it rains, use a dense net to stop or sprinkle some lime in the ditch to prevent escape. The mink breeding cycle is a year and a half. The largest individual can reach 65 grams, and the average is about 35-50 grams. The mu yield can reach more than 100 kilograms. According to the current market conditions we understand, Anhui Shengzhou herbal medicine market water è›­ (clear water) 155-165 yuan / kg (October 15th). Mink breeding is an emerging breeding industry. At present, there are not many people who are truly proficient in mink breeding techniques. Whether it is indoor breeding or outdoor simulation of natural farming, due to some irresponsible misleading propaganda and incorrect technical guidance, many people have failed to breed. Therefore, it is necessary to solve the problems of breeding techniques and market sales before breeding.
