Problems solved by technology

However, most of them are cultivated in the wild in a natural environment, and the breeding time is relatively long, and the predators continue to eat them during the growth process.
The high temperature in summer and the severe cold in winter have caused the production of leeches to be unable to effectively increase. At present, leeches are generally cultivated in ponds and pits, which occupy a large area and are not suitable for family garden cultivation.
There were also many invention patents before, but they were not practical. The leech bait died seriously, the water was polluted, it was difficult for young leeches to find food, the growth was slow, and even if they did not grow, they naturally became emaciated to death. Rise, pharmaceutical companies purchase at high prices, patients buy medicines at high prices, resulting in a vicious circle

[0025] Preparation of underground water source: Drill an underground well with a water output of 30-100 cubic meters per day. Selection of drying ponds: Excavated in January, a rectangular pond with a width of 6 meters, a length of 50 meters and a depth of 2.3 meters, A, B, C, D, E, F ( image 3 ), the ponds are all paved with plastic film, the main purpose is to avoid water turbidity in the later stage, plant aquatic plants in nutrient pots in ponds B, C, D, E, and F, the height of the overflow pipe at the mouth of F pond is 2 meters, and the height of the overflow pipe at the mouth of AB, BC, CD , DE, and EF ending misplaced pipelines are connected.

[0026] Breeding leech bait pond preparation: Excavation G, H, I, J, K pond mouth ( Figure 4 ), 6 meters in width, 50 meters in length, and 2.3 meters in depth. After the ponds are dug, 100 mesh anti-escape nets will be placed around them, and more than 50% of the area of ​​aquatic plants will be planted in each pond after ent...

Description

technical field [0001] The invention relates to leech cultivation, in particular to a garden-style three-dimensional cultivation method for leeches. Background technique [0002] Leeches are traditional Chinese medicinal materials, and they are the main raw materials for treating stroke, hemiplegia, hypertension, amenorrhea, and cardiovascular and cerebrovascular diseases. The environment where leeches grow is polluted by pesticides, chemical plant sewage, and domestic garbage. Due to the serious shortage of leeches, leech farming has developed rapidly in my country in the past 20 years. However, most of them are cultivated in the wild in a natural environment, and the breeding time is relatively long, and the predators continue to eat them during the growth process. The high temperature in summer and the severe cold in winter have resulted in the inability to effectively increase the production of leeches. At present, leeches are generally cultivated in ponds, which occupy ...
