1. Shrimp farming in a greenhouse requires heat preservation, and the water temperature in the greenhouse must be kept above 20°C during the coldest time. It is best to use a double-layer membrane for the greenhouse. It is best not to use film on the sides, but to use color steel plates with insulation materials. The height should not exceed three meters. Since the span of this kind of greenhouse is relatively large, the span of a greenhouse like Yang Huixi's has already reached 24 meters. Therefore, while considering the good thermal insulation effect, you should also consider the issue of load-bearing. The scaffolding can choose a wooden structure or a rigid frame structure according to the conditions.

2. The greenhouse adopts this arched structure. According to the principle of mechanics, this arched structure has better bearing capacity. Especially in the north where there is more rain and snow, the arched structure is easy to clean up the rain and snow. It can guarantee the use of the greenhouse for many years. Each pond can be designed as a two-meter structure, so that the span of each arch is only 12 meters, which greatly increases the sturdiness of the greenhouse.

3. Using greenhouses to raise shrimp can increase the density of shrimp stocking. Generally, the density of shrimp stocking in greenhouses can reach 120,000 to 150,000 per mu, which is three times the original stocking density of pond culture.
