Embodiment 1
[0011] On March 18, 2008, the species was selected, and the leeches were biennials with strong body and obvious genitalia as the kind of leeches, and 10,000 kinds of leeches were selected; Throw in a spawning pool of 100 square meters, feed 100kg of snails 2 days after planting, keep the water level in the spawning pool at a depth of 30cm, collect cocoon eggs manually 10 days after spawning, and divide them into two batches, with an interval of seven days between the two batches. 16,000 cocoon eggs were obtained for the first time, and 14,000 cocoon eggs were obtained in the second batch. Put the cocoon eggs into the incubator, spread a layer of wet soil 1.5cm on the bottom of the square incubator, then put the cocoon eggs on the wet soil, cover After putting on the cloth, cover the cloth with a layer of 2cm thick wet soil. There are holes around the incubator to keep enough air in the box; the indoor temperature is kept at 20°C and the humidity is 70°C. Half of the first batch...
