Method for high-density green ecological culture of blood-sucking leeches
The invention relates to a method for high-density industrial culture of blood-sucking leeches, which belongs to the technical field of artificial culture of the blood-sucking leeches. The culture method cultures commercial leeches artificially by the steps of selecting a place, building a pond, putting leech seeds into the pond, feeding the leech seeds, preparing cocoon producing beds, producing cocoons and hatching the cocoons, culturing young leeches, living through the winter and the like, and achieves recirculation culture by the steps of producing the cocoons and hatching the cocoons. In the culture process, when the reproduction rate of the cultured leeches goes down after three generations of close breeding, the cultured leeches are mated with wild leeches to achieve the aim of the rejuvenescence of parent leeches. The culture method solves the problems that the changes of the natural environment and the increment of pollutant sources make naturally-growing leech sources decrease day by day and the gradually expanded market demand cannot be satisfied. The culture method for culturing the leeches has less investment but high production. The input of 100 kilograms of the leeches can yield 200 kilograms of the commercial leeches. The culture method can culture the leeches not only by building large vinyl tunnels and ponds, but also by using rural homesteads, yards or vacant houses for building the ponds, and has good economic benefits.

The invention relates to a drought-resistant sweet potato variety rapid breeding method, and relates to the technical field of hybridization breeding. The breeding method comprises the following steps: F1 generation hybrid true seeds are obtained through directional crossing or polycrossing; drought resistance screening and identification are carried out; and rapid propagation and breeding are carried out. According to the invention, the F1 generation true seeds are obtained through the method of directional crossing or polycrossing, such that the probability of a salinity-tolerant variety in the offspring is greatly increased. The salinity-tolerant sweet potato line identification is put to a first round (a technical prejudice is overcome because first-round selection is carried out according to yield and quality level), such that the inclusion of a salinity-tolerant single plant in the hybrid offspring is ensured to a maximal extent, and materials without salinity tolerance is rejected. Therefore, the selected single plants are greatly reduced, and field identification work load is substantially reduced. A remote multi-site yield comparison test can be completed in one time, and breeding time is shortened by 2-3 years. The method also has the advantages of high accuracy, low blindness, and high efficiency.
