You can choose a plastic basin with smooth inner wall, with a height above 15 cm and a diameter above 45 cm. Built-in feeding soil can be directly cultivated. Eggs can also hatch in pots, and hatched larvae can be raised in pots according to their size. Potted plants are suitable for small-scale farming, with less investment, convenient operation and flexible movement. The disadvantage is that the temperature and humidity are difficult to control and the output benefit is low.

2, cylinder maintenance

Tank culture is generally suitable for non-heating or micro-heating culture. Tiles and pots with smooth inner walls shall be selected, the height of which shall not exceed 1 m, and half or part of them shall be buried underground. Feeding soil can be placed 40-50 cm thick, and the hibernation period of Eupolyphaga sinensis can be shortened when the temperature is 0-20 degrees in spring and autumn. Its advantages are stable underground temperature and humidity balance, good growth, long service life and good output quality of soft-shelled turtle. Disadvantages are long cycle, low yield per unit area and easy to be destroyed by rats.

3. Pond culture

Planar pond culture is the predecessor of three-dimensional greenhouse pond culture. Build a 40-45cm high square pool with bricks on the indoor concrete floor, leaving a walkway of1m. The pool is built on both sides or completely built indoors, and planks are laid for walking operation. At the same time, stick 6-8 cm wide glass strips on the upper edge of the surrounding inner wall (thick film can be used instead of glass strips) to prevent water turtles from escaping. Can be heated for cultivation, doors and windows and surrounding walls should be sealed to prevent rats and ants. The advantages are: good growth of insects, convenient management and less investment. Disadvantages are long cycle and low utilization rate per unit area.

4. Stereoscopic pond culture

What we advocate is a more advanced greenhouse three-dimensional farming model. Its advantages are one-time investment, years of benefit, fast output and high efficiency. However, the investment is large, and it costs about 5,000 yuan to build a three-dimensional aquaculture pond with a square meter of/kloc-0. Farmers should determine the breeding form according to their own conditions.

In the process of artificial culture of Eupolyphaga Seu Steleophaga, heating culture can shorten the growth cycle of Eupolyphaga Seu Steleophaga by two thirds. Although heating increases the cost of farming, it is insignificant compared with the income. Stereoscopic pond culture needs more heating. Because the three-dimensional cultivated Eupolyphaga sinensis is not deeply buried, in the cold winter months, Eupolyphaga sinensis can't stand the surrounding cold and dies. The specific requirements and practices of three-dimensional pond culture are:

First, the house. The house where the health pool is built does not leak, and the surrounding walls are intact and flat. If the terrain is low, ditches can be dug outside the enclosure for drainage. Generally, the height of a house is more than 2.6 meters, the width is about 3.6 meters and the length is 8- 12 meters. If the original doors and windows are not in the center of the aisle, they should be changed to the center, with the width not exceeding 1 m, the window height not exceeding 1.5 m and the door height not exceeding 2 m.

Second, the wall. Mud brick, red brick and cement brick wall can be used, but one side should be painted with cement mortar. After leaving doors and windows at both ends of the house, two partition walls are built with vertical bricks, and the gap between walls is 5- 10 cm. When building a partition wall, build a top brick at regular intervals to resist the original old wall to prevent the partition wall from collapsing. There is only a partition wall and perlite in the empty layer. In this state, the house of Eupolyphaga sinensis is warm in winter and cool in summer, and it is like a basement all year round, which can ensure the normal growth of Eupolyphaga sinensis all year round.

Third, the pool body. After the partition wall is completed, a 1 m walkway will be reserved according to the remaining area in the house. Design the size of the feeding pond plate (the size of the pond plate should not be too large, generally around 1 m2), and the thickness of the feeding pond plate is 3-3.5 cm. After the size is determined, it will be poured with reinforced concrete, and 4 mm steel bars will be selected. After the pool board is poured and maintained, the three-dimensional pool can be built. Each floor has 3 vertical bricks (about 40 cm high). After the first floor is built, paint the interior wall, and then you can lay another layer of billiards board. It can be built with 6-7 floors and capped at the top. Spread grass or other thermal insulation materials in the gap between the pit top and the roof. Leave an operation window of 19-20 cm on one side of the tunnel. Last week, the operation window was pasted with hard plastic paper about 4 cm from the protruding pit to prevent the ground beetle from escaping (note that glass strips cannot be used here, which will scratch the arm during the operation). After the pit house is built, the surrounding rooms should be painted and filled with gaps to prevent rats and ants from entering.

Fourth, heating facilities. Brick 1-2 ground fire dragon is built in the breeding room. It is more suitable to use honeycomb coal or raw coal for heating. The ground fire dragon is set on a plane, and the heat source rises slowly from bottom to top. Even if the furnace goes out for several hours, there is still residual heat on the ground fire dragon. The combustion furnace can be arranged outdoors or indoors. There should be a cover on the indoor stove to prevent gas leakage. Exhaust gas after combustion is discharged to the outside.

There are many ways to keep warm, so we should adjust measures to local conditions. Here are some common heating methods.

1 is an electric heating method: it is more convenient and easier to operate with an electric stove or heater. It is best to use a humidification heater. You can put a pot on the electric stove to boil water to increase the humidity of the air. Electricity is pollution-free, but the cost is high. Attention should be paid to the safety of electricity, which is generally used when the temperature of hatching eggs is not enough in winter.

2. It is a heating mode of coal stove: ordinary coal stove is equipped with pipes to dissipate heat, and at the same time, exhaust gas is discharged to the outside. The exhaust pipe dissipates heat quickly, which will cause the temperature to rise and fall when heating, and the pipeline is easy to be damaged. The leakage of damaged waste gas is easy to cause gas poisoning of operators. In winter, the doors and windows are closed, and the oxygen burned by the coal stove should be supplemented. This method has the advantages of small investment, convenience, flexibility and rich practical experience, and has been adopted by some family farmers.

3. It is the method of ground fire dragon heating: there are 1-2 brick ground fire dragons in the feeding room. It is more suitable to use honeycomb coal or raw coal for heating. The fire dragon is set at the ground level, and the heat source rises slowly from bottom to top. Even if the fire dragon goes out for several hours, there is still residual heat. The combustion furnace can be arranged outdoors or indoors. Cover should be set on the indoor stove to prevent gas leakage.

4. It is a steam pipeline heating method: large-scale farms with conditions can use boilers to burn steam and pipeline it to the cellar for heating. The one-time investment is large and can be used for many years. The hot water produced by the boiler can be used for brewing feed, scalding insects and so on. Adding a switch to humidify the pit room is really a win-win situation. Its investment is large and small farmers can't adopt it.

There are many ways of heating, so we should adjust measures to local conditions. There is only one purpose, that is, to increase the temperature of the pond in winter, shorten the growth cycle of Eupolyphaga sinensis and improve economic benefits.
