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.

Indoor-outdoor multi-crops polyculture method for shrimp, soft-shelled turtle and fish

An indoor-outdoor multi-crops polyculture method for shrimp, soft-shelled turtle and fish includes building an upper greenhouse culture pond and a lower outdoor intensive culture pond, and using a transfer pipe to communicate the upper greenhouse culture pond and the lower outdoor intensive culture pond; throwing desalted giant tiger prawn in the upper greenhouse culture pond in mid-March, and keeping water temperature at 25 DEG C; pouring water into the lower outdoor intensive culture pond prior to throwing in silver carp, bighead carp and Chinese soft-shelled turtle for breeding in early May; after seedlings grow to about 5cm 50-60 days after culture of the giant tiger prawn in the upper greenhouse culture pond, transferring young shrimps in the upper greenhouse culture pond into the lower outdoor intensive culture pond for breeding through the transfer pipe, harvesting first crop from late June to early July; and harvesting the silver carp, the bighead carp and the Chinese soft-shelled turtle in November to December after continuous three-crop culture of the giant tiger prawn. The indoor-outdoor multi-crops polyculture method for shrimp, soft-shelled turtle and fish breaks through the bottleneck of existing culture production and benefit.

Culture method of meat rabbit

The invention relates to a culture method of meat rabbits. The culture method comprises the following steps: (1) making a rabbit hutch: enabling the ground height in the rabbit hutch to be 20-30cm from the ground outside the rabbit hutch, dividing the rabbit hutch into small rooms with the length being 70-80cm and the width being 60-70cm, and arranging feces supporting plates in the small rooms, wherein a door of the rabbit hutch is woody; (2) performing daily management: maintaining the temperature in the rabbit hutch to be 10-30 DEG C; simultaneously, paying attention to ventilation and air change in the hutch so as to reduce the stimulation of ammonia gas generated by feces on the rabbits; feeding each rabbit one piece of oxytetracycline once in every 2-3 months to prevent occurrence of cold and pneumonia, wherein feedstuff comprises concentrated food and forages, the feeding at high-temperature period is avoided, the preferred feeding is twice per day, i.e., in the morning and the evening, drinking water is supplied sufficiently, and a little amount of salt iodine tincture is added into the drinking water. The culture method is simple, the requirement for equipment is low, the illness rate is obviously reduced, the meat quality of the rabbits is good, and the taste is good, so that the culture method is especially suitable for large-scale culture in rural areas, especially the areas with hard conditions.

Drought-resistant sweet potato variety rapid breeding method

InactiveCN105010127AIncrease the selection rateFast identification methodPlant genotype modificationBiotechnologyGenetic stock
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.
