Embodiment
The invention discloses a kind of Cyclemys trifasciata hatching method, adopt this hatching m can effectively improve hatchability, and can rationally control the sex ratio of hatching young tortoise, the quantitative proportion of female and male young tortoise is rationalized, this Cyclemys trifasciata hatching method comprises following operation sequence:
(1), get the raw materials ready: small water turtle was got river sand, clay ready and is uniformly mixed into sandy soil between the expected date of childbirth, inserted uncovered casing or perisporium and had in the casing of ventilation hole stand-by through the sun sterilization of being exposed to the sun;
(2), collect fertilized egg: small water turtle was laid eggs back 24 hours in, selects fertilized egg and it is imbedded in the sandy soil with the degree of depth at a certain distance, casing was moved to indoor;
Incubation condition: casing indoor air humidity of living in remains on 80%～90%, the water content of sandy soil is controlled at 6%～8% in the casing, if the male larger proportion that accounts in the young tortoise that need hatch, then the sandy soil temperature is controlled at 25 ℃～27 ℃, if female tortoise accounts for larger proportion in the young tortoise that need hatch, then the sandy soil temperature is controlled at 29.2 ℃～29.8 ℃.
(3), regularly check: checked every 2～3 days and once to hatch situation, find that bad ovum in time removes.
During practical operation, need the sandy soil on small water turtle is laid eggs preceding scarifying, the spawning ground of being exposed to the sun, in case of necessity it is carried out disinfection, sandy soil humidity is pinched agglomerating, promptly diffusing being advisable of loosing one's grip with hand.Need careful procuratorial work every day to wait to produce small water turtle and spawning ground between the expected date of childbirth at small water turtle.Then get casing ready when the vestige of finding to lay eggs, casing can be bubble chamber, carton or plastic box, and the neglecting fertilized egg quantity greatly of casing and deciding generally selects the length and width height to be respectively 40～80 centimetres, 40～80 centimetres, 40～60 centimetres casing.The casing that is used to hatch can be uncovered casing, also can be the casing that perisporium has ventilation hole.In casing, put into the sandy soil after the sun is exposed to the sun sterilization of 15～30 centimetres of thickness, laid eggs back 24 hours at small water turtle, adopt the method for light-illuminating tell fertilized egg and with its collection, imbed in the sandy soil, when with light-illuminating tortoise ovum, if ovum central authorities' adularescent annulus or hickie then are fertilized egg.
During hatching, the moist degree of sandy soil and air humidity directly influence the embryonic development of fertilized egg, air humidity is excessive, the sandy soil water content is too high, cause the fertilized egg necrosis that suffocates easily, air humidity is too small, the sandy soil water content is low, then fertilized egg easily " is dried up " downright badly because of the moisture excessive evaporation, therefore the humidity of sandy soil is controlled at 6%～8%, casing environmental air humidity remains on 80%～90%, helps embryo's normal development of fertilized egg most.Temperature plays an important role in hatching process, and the height of temperature influences the length of embryonic development speed, incubation period and the sex of young tortoise.Generally speaking, in 22～33 ℃ of scopes, the high more embryonic development of the temperature time faster, that hatch is shorter, otherwise then the embryonic development time slow, hatching heals long.Therefore, when being controlled at the sandy soil temperature in 25 ℃～27 ℃ scopes, can make the most of young tortoise that hatches be male, when being controlled at the sandy soil temperature in 29.2 ℃～29.8 ℃ scopes, can make the most of young tortoise that hatches be female.
Sandy soil thickness is advisable with 15～30 centimetres in the casing, in order to ensure that sandy soil have air permeability and good and water binding capacity concurrently, the mixed proportion of river sand and clay is 0.8: 1～1: 0.8 in the sandy soil, this ratio helps making sandy soil to keep suitable humidity and air circulation, fertilized egg is hatched in suitable environment, effectively improve hatchability.Fertilized egg is imbedded to cross in the sandy soil and is occurred fertilized egg suffocating deeply easily, imbedded the shallow influence that changed by ambient temperature and damp condition, therefore the degree of depth imbedded in the sandy soil of fertilized egg is advisable with 8～14 centimetres, and this depth bounds can better ensure that fertilized egg hatches in the condition of constant temperature and humidity.The spacing of fertilized egg should be at 2～5 centimetres, and this distance range had both given fertilized egg enough incubation spaces, keep each fertilized egg not interact, and ensured the uniformity of incubation condition again.The particle diameter of river sand is 0.3～1.0 millimeter in the sandy soil, the particle diameter of clay is 0.05～0.2 millimeter, particle diameter is that 0.3～1.0 millimeter river sand can make sandy soil keep air permeability and good, and particle diameter is that 0.05～0.2 millimeter clay then makes sandy soil have water binding capacity preferably, plays the constant temperature and humidity effect.Certainly, can also join in sandy soil in case of necessity that particle diameter is arranged is 0.3～0.7 millimeter vermiculite, it mainly acts on and is sandy soil are played insulation effect, also has the effect of mould fungus inhibition growth, virus killing in addition, ensures that fertilized egg is not infected.
