Feeding soft-shelled turtles with green feeds has a low investment cost and considerable benefits, and it is widely used in rural areas. By using green feed to raise the snails and then raising the soft-shelled turtle, the green feed can be converted into animal feed to meet the dietary requirements of the turtle. The commonly used snails are snails, which have high nutritional value, rapid reproduction, and high yield. They can provide sufficient feed for turtles for a long time and promote the growth of soft-shelled turtles. The turtle eats snails that are 45 days old, weigh about 20 grams, and live under the water. Feeding soft-shelled turtles with green feed should note the following:
1. In addition to knowing the basic techniques of turtle culture, it is necessary to master the high-yielding culture techniques of A. sinensis. If the yield of snails is low, the conversion rate of green fodder will be reduced, and turtles will not be able to obtain high yields.
2. Be sure to choose green snails feeding snails. According to local observations, the green fodder preferred by the snails was alpinia, water hyacinth, water hyacinth, cabbage, leeks, cabbage, eggplant, wax gourd, white melon, pumpkin, peanut vine, and steamed bread, and the concentrate had rice bran and corn. Powder, bran, peanut cake and so on.
3. Each time a turtle is put into a snail, there is a process of spawning and hatching due to snails, so in the first month, other turtle feed must still be fed.
4. Snails should not be used for nursery turtles because they have low foraging ability and are difficult to use. To raise the baby turtles, the juvenile snails must be removed and the snails must be removed and chopped into the food dish before they can be used effectively.
5. Snails are more sensitive to dissolved oxygen in water. The higher the dissolved oxygen in water, the better the growth. When the water solubility is less than 3.5 mg per liter, it will not be consumed, and it will die if it drops to 1.5 mg. Therefore, aquaculture ponds can best drain and drain. If the static water tank should be changed frequently, it is best to install oxygen equipment. The pH of the water is neutral, and it is also possible to put appropriate amount of earthworm, squid, or tilapia in the culture pond to allow them to consume feces and microorganisms of the soft-shelled turtle and snails to purify the water.
Another point that needs to be reminded to the farmers is that they have been listed as China's 16 species of biological invasive species and must be guarded against escape. In the future, if turtles are not raised, the snails and eggs must be completely killed to avoid damage to rice and other economic crops.

The main features:
1)Ideal cold light effects
Using the new LED cold light source, ensure energy saving and environmental protection and long service life up to 80,000hours and more.
The temperature increase of surgeon`s head below 1â„ƒ. LED do not engender infrared ray and ultraviolet radiation, without the temperature
rise and tissue damage caused by halogen shadowless light, also it can accelerate the wound healing after surgery, and without Radiation pollution.
With color temperature constant and soft, LED is very close to the sunshine.
1) Excellent shadowless effect
Lamp with the most scientific radian and Multi point light source design, ensure better uniform illuminance. When the lamps are partially occluded,
also can achieve perfect shadowless effect.Lamp panel radius of gyration â‰¥182cm, the lamp can be pulled to vertical floor, convenient to any angle illumination.
2) Excellent deep lighting
It is based on modularize method by Computer Aided Design, focused to irradiating with more beams of LED. It produces the deep lighting which beams
more than 1200cm,the illumination of center up to 180,000Lux or more, and offer the color temperature that can be adjusted from 3700K to 5000K which
is close to sunshine. Absolutely, it really reflects the color of human tissue and satisfied by all kinds of operating light needs.
3) Advanced control system
The use of liquid crystal display button control, to meet the needs of the medical staff of different patients with the brightness of the operation.
It offers illuminance memory function.
It does not effect using when a single circuit or one bulb is broken.
4) Universal suspension system
Rotating arm, a new type of alloy material is made of eight edge type.
Balanced system using imported arm module, more than 5 group universal joints, every cantilever must has more than 3 joints which can be rotated in 360Â°,
The structure is light, easy to manipulate, accurate positioning, can provide the maximum range of regulation.The equipped with fatigue correcting unit and
fix position hand handle device, easy to fix position after long time use.
5) Modern laminar lamp
The thickest part of lamp-chimney is not more than 10cm.
The lamp-chimney is made of ABS, The handle on the central of lamp can be detachable, can take high temperature (â‰¤ 134Â°C) sterilization treatment,
easily adjust, flexible fixed.
