By using white earth to cultivate turtles, the turtle's living environment is spacious, and there is good light and sufficient conditions for dissolved oxygen in the water. When the food is widely used, it can be eaten freely. The physiological habits of the turtle are satisfied and the growth rate is accelerated. Haining City Haining City, Zhejiang Province Leading House amphibious reptile animal research institute, in Pak Pak Tin stocking turtles and snapping turtles, and achieved significant economic benefits. The techniques for using aquatic turtles from Pak Tin are described as follows:
I. Facilities in Baitian
Select water source conditions are good, can discharge irrigation, flood water is not flooded fields, drought is not water shortage fields. Around the field, turtles were required to establish anti-escape facilities, and water inlets and outlets were barbed or plastic mesh bars. Field excavation of "Tian"-shaped ditch for turtle activity and wintering. The side ditch is shallow and narrow; the middle ditch is deep, wide, and the side ditch is 1.2m wide and 0.8m deep; the middle ditch bottom is 2m wide; the ditch is 3m wide and 1.5m deep; the ditch area accounts for 20% of the land area. Tian Zhongjian builds a spawning beach in the north-south direction. It is 5 meters long and 1 meter wide at the top. It is above the normal water level and has a certain slope. It is convenient for turtles to go ashore.
Second, the turtle's stocking
1. Species selection: Snapping turtles, colorful turtles can be bred into commercial turtles that year, other species can choose yellow-throated turtles, tortoises and so on.
2. Stocking specifications: The turtle stocking specifications are in the range of 150-200 grams. According to the experience of the leading museum of amphibians and reptiles in Haining City, Zhejiang Province, this specification has been cultivated for 6 months. The colorful turtle can reach 500 grams and the snapping turtle can reach 1000 to 1500 grams.
3. The time and quantity of stocking: After transplanting and survival, you can stock up to 300 to 500 per mu. If you want to breed hatchlings, you can add 50 to 60 turtles. Snapping turtles are stocked with 50 to 100 acres and require that the stocked turtle be even in size to facilitate the growth and development of the turtle.
4. Livestock stocking: In order to allow turtles to eat freely, with little or no artificial feed, mu can be used for 4,000 to 5,000 snails, 7,000 to 8,000 mud, 4000 to 6,000 fresh shrimps, and turtles can be used to grow water. Floating lotuses, field flats, etc. are used for feeding turtles, snails, clams, and shrimps, and are also white organic fertilizers.
Third, field management
1. Feeding or supplementary feeding should be fixed, timed, quantitative, and qualitative.
2. Water quality Water temperature has a great influence on the growth and development of turtles. Attention should be paid to observe water quality and change water in a timely manner. Pay attention to controlling the water level, and adjust the water temperature and high temperature to increase the water level. Do not use the water in the fields to irrigate the fields.
3. Pay attention to preventing escape, leaking, preventing poisoning and preventing the harm of snakes, rats, birds, insects, etc., and insist on daily field inspections to strengthen guards.
4. Live replenishment in time.
5. Pest control measures for pests and diseases in cultivated white fields: Use biological control as much as possible, use less pesticides, and prohibit the use of pesticides such as buprofezin, imidacloprid, chrysanthemum pesticides, methamidophos, 1605, omethoate, carbofuran, etc. When using a hand sprayer, a spray nozzle with an orifice of 0.7 mm must be used. At the same time, the upper part of the plant should be sprayed to reduce the amount of liquid that falls into the water. Spraying should be carried out after the dew is dry on a sunny day. In case of improper application of pesticides and excessively high concentration of pesticides, the “running horse water†should be quickly filled to ease the reduction of phytotoxicity.
