Soft-shelled turtle hatching method and special incubator

Abstract

The invention relates to a soft-shelled turtle hatching method, which comprises the following steps of: (1) stacking fertilized soft-shelled turtle eggs layer by layer on the surface of a sand layer of a hatching tray in an incubator, wherein the thickness of the sand layer is 2 to 3 centimeters, and the water content of the sand layer is 7 to 8 percent; (2) covering a sand layer with the thickness of 2 to 3 centimeters and the water content of 7 to 8 percent on the soft-shelled turtle eggs; and (3) after the steps (1) and (2) are finished, regulating the temperature in the incubator to be 33 to 34 DEG C, keeping the relative humidity of air at 85 to 88 percent, ventilating for 1 to 2 hours at noon of every day in the hatching process, and finishing hatching of the soft-shelled turtle eggs after 43 to 45 days. The hatching method is simple and feasible; the special incubator is scientific and reasonable in design and convenient to operate; and manpower is greatly saved, the hatching cost is reduced, the survival rate of soft-shelled turtle fries is improved, and economic benefits of an enterprise are increased.

Description

technical field [0001] The invention belongs to the field of soft-shelled turtle breeding, in particular to a soft-shelled turtle hatching method and a special hatching box thereof. Background technique [0002] Soft-shelled turtle, also known as "turtle", is not only a delicacy on the table, but also a valuable tonic because of its delicious meat, rich nutrition and high protein content. Not only that, all parts of the soft-shelled turtle can be used as medicine, which has the functions of nourishing yin and clearing heat, opening the liver and benefiting harmony, breaking knots, softening and relieving stasis, etc. The blood of soft-shelled turtles also has the effect of treating anemia, lung disease, heart disease, asthma and neurasthenia , is even more precious. [0003] In the soft-shelled turtle breeding process, hatching is a very critical step. The hatching process not only affects the survival rate of the seedlings, but also relates to the system and body shape of ...

AI Technical Summary

Problems solved by technology

[0004] In the incubator during the hatching process, multiple hatching trays are placed on the frame-type support, and a layer of sand is placed in each hatching tray. The soft-shelled turtle eggs are buried in the sand layer, and the hatching of soft-shelled turtle eggs is completed by controlling various parameters. , these incubators have a simple structure and are easily affected by the external environment. All control parameters are manually detected and adjusted. Therefore, it is difficult to control the temperature and humidity of the soft-shelled turtle hatching in an ideal state, resulting in a longer incubation period and a lower hatching survival rate. , and the sand in the incubator contains more bacteria and viruses, even if the soft-shelled turtle eggs hatch out, they will be infected and easily die. The above two reasons lead to the hatching survival rate of soft-shelled turtle eggs is only 50-60%, which leads to the economic loss of farmers. loss
