Video of leech culture technology

Leech culture is the use of wild leeches and other creatures that have been domesticated by human beings. at present, there are the physiological functions of wild leeches such as money wide-body leeches and phenanthrene leeches, which can transform feed and other organisms into biological energy through artificial breeding and breeding. in order to obtain the body of leeches and the production of biological products such as medicinal materials. It is a very important part of material exchange between human beings and nature. Leech culture is not only a new thing in modern agriculture, but also an important way to develop traditional Chinese medicine.

Marsh and bog culture

Marshes and bogs are rich in aquatic plants, rich in organic matter and humus, and rich in plankton and aquatic plants. Therefore, as long as fences are built to prevent escape and prevent natural enemies. The investment cost of this model is low, and it is troublesome to manage and fish.

Rice field intercropping

As the main activity places of leeches, digging ditches and sliding ditches in rice fields are generally excavated in the shape of "well" and "ten", which can be divided into two types: trench type and mud pond type. The gully is required to be evenly distributed and extend in all directions, which is conducive to the growth and foraging of leeches, with a width of 0.4 meters and a water depth of 0.3-0.5 meters, and the area of the gully accounts for about 10% of the total area. Mud ponds are dug inside the rice fields, and the mud ponds are connected with the ditches in the rice fields. The width and depth of the ditches are about 0.4 meters and 0.5-0.6 meters, accounting for about 15% of the rice field area. Pay attention to the harm to leeches caused by pesticide application in rice fields. Generally choose high-efficiency and low-toxic pesticides, and do not use chemical fertilizers, it is better to use animal manure, which is not only conducive to a good harvest of rice, but also a good feed for leeches.

Cement pond culture

Build a cement pool of about 20 square meters, 3 meters wide, 7 meters long, 1 meter to 1.2 meters high and 0.5 meters deep. Water plants and other plants need to be put into the outdoor cement pool for leeches to inhabit. The newly built cement pool can not immediately put seed leeches, and the alkaline substances (Portland cement, calcium hydroxide, etc.) in the newly built cement pond can not be put into seedlings until they are desalinated for 20 days. After the overall environmental conditions of the culture pond tend to the overall balance of the food chain, the amount of seed can be gradually increased, generally 100 per square meter.

Standardized intensive breeding

It is suggested that the pond should be 90 meters long, 7-8 meters wide, 1.2-1.5 meters deep, 0.5-0.6 meters deep, build soil habitat 0.3 meters above the water surface, plant aquatic plants for shade and sunscreen, and use 40-mesh polyethylene mesh to prevent escape. Generally, 2000 leeches are planted per mu of water.
