Today, we advocate a more advanced three-dimensional culture mode in greenhouse. Its advantages are one-time investment, multi-year income, fast output and high efficiency. However, the investment is large, and it will cost about 2000-3000 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, or they can build several layers of shelves with ironwood materials and put them in plastic pots for breeding. However, due to the high humidity in the feeding room, the ironwood material is easy to rust and rot, and its service life is not long.

The house where the health pool is built should not leak, and the surrounding walls should be intact, even if the top is flat. If the terrain is low, you can dig a ditch of 0.5-0.8 meters around the house for drainage. The height of the house is generally more than 2.6 meters, and the original doors and windows are not moved as much as possible in the middle of the aisle. If the doors and windows are too large, they should be smaller, the width should not exceed 1m, the window height should not exceed 1.5m, and the door height should not exceed 2m. Leave doors and windows around the interior wall, and build a partition wall with vertical bricks, with a distance of 5- 10 cm from the original wall. Use top bricks to build partition walls against the original old walls at intervals to prevent the partition walls from collapsing. One side of the partition is painted. The function of partition wall is to keep warm and moist. In this state, Eupolyphaga house is warm in winter and cool in summer, and it is like a basement all year round, which is of great significance to cultivate Eupolyphaga.

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 pit plate (the size of the pit plate should not be too large, generally around 1 m2), and pay attention to leave a gap of 5- 10 cm on both sides. The thickness of the feed pit 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 pit plate is poured and maintained, the three-dimensional pit pool can be built. There are three vertical bricks on each floor (about 40 cm high), and a layer of back inner wall is built. After painting, another layer of pit board can be laid, which can be capped with 6-7 layers. Grass or other thermal insulation materials are laid in the gap between the pit top and the roof. Leave an operation window of 19-20cm on one side of the tunnel. Last week, the surgical window was glued with hard plastic paper about 4 cm protruding from the pit to prevent Eupolyphaga from escaping. (Note that you can't use glass strips here, as the glass strips will scratch your arms during operation. After the pit house is built, paint the surrounding rooms and fill in the holes to prevent rats and ants from entering.
