Choose turtles that have a complete appearance, no disease, no deformity, bright body surface, and strong constitution. The female 1.5 kilogram or more and the male 0.5 kilogram or more will be selected as brood turtles. The single greenhouse pool should be 1050 square meters, the pool depth should be 0.8 meters, and the pool water depth should be 0.5 meters. The vertical pool wall of the outer pool should be 500The greenhouse should have a brick-concrete structure, with smooth pool walls, and an overflow outlet 0.2 meters above the upper edge of the pool wall. The pool must be equipped with aeration equipment. The outer pool is usually surrounded by brick walls or cement boards. The outer pool is usually surrounded by brick walls or cement boards. The surface must be smooth and solid, and should be 0.4 meters above the ground and buried underground(1) Collection of fertilized eggs 24 hours after the eggs are laid, start collecting after the bright area (clear and translucent area in the center of the turtle embryo) appears. Fertilized eggs should be large, shiny, and have an obvious fertilization point. (3) The incubation substrate is laid on the bottom of the incubator with river sand (washed and disinfected) with a particle size of 0.50.8(5) The air humidity is generally controlled at around 80% (the difference between dryness and humidity is 2℃), and the moisture content of the matrix river sand is 7%After the turtle hatchlings hatch, they are very young and cannot be put into the pond immediately. They should be temporarily raised in clear water in smooth ceramic or plastic basins for 1224 hours. The fallen umbilical cord should be removed in time. After the umbilical cord shrinks, the turtle hatchlings can be placed in the turtle breeding tank for cultivation. (1) The hatchlings are temporarily raised in the greenhouse for 3040 days, with a density of 80 turtles2)防病消毒干池消毒:每亩(1亩=667平方米)用生石灰75千克或漂白粉8 mg / liter, and the soaking time is 15 ~ 30 minutes. Saprolegnia: You can use 0.4%0.5% of salt and baking soda mixture poured into the whole pool or 3040 mgWhite spot disease: You can apply cephalosporin ointment to the affected area or take Houttuynia cordata, isatis root, honeysuckle, wild chrysanthemum, etc., 60g per kilogram of body weight for / days, and use 3(4) stocking density specification58g/ only, stocking density is 800.150.2 meters, and the water needs to be changed 1 times 1520 days.When the specifications are 200 grams/, the stocking density is 30/ square meters, and the daily feeding amount is about 2%5.Fishing and transportation
