How to build a breeding shed

The construction method of the breeding greenhouse is as follows:

1. Take the construction of plastic breeding greenhouse as an example. Generally, the span of greenhouse is 6- 12m, the bay is about 4m, and the eaves are 3-4m high. But the width of greenhouse is different with different ventilation types.

2. Generally, in a naturally ventilated multi-span greenhouse, when the side window and the roof window are used together, the maximum width of the greenhouse should generally be within 50m, preferably around 30m. However, the maximum width of mechanical ventilation multi-span greenhouse is generally expanded to 60m, and it is appropriate to limit it to about 50m, and the length is generally within100 m.

3. Hot-dip galvanized steel pipes are usually used as the main load-bearing structure in plastic greenhouses. However, due to the light weight of the plastic greenhouse, its top has weak ability to resist wind and snow, so it needs proper support to maintain the stability of the whole greenhouse.

How to prevent wind and water in breeding greenhouses?

1. Excavation of drainage ditch

Before the typhoon comes, vegetable farmers must pay attention to check whether the drainage ditches around the shed are unblocked and clean them in time to prevent rainwater from pouring into the shed. If there is no drainage ditch, it is necessary to set it up quickly. We can dig a ditch 30 cm wide and 40 cm deep in front of the shed.

2. Keep the shutter.

Except for the exposed part, the head of the shutter should also be coated with antirust paint, and the part that is easy to penetrate into the internal water should be wrapped in advance. It is best to apply antirust paint first, and then wrap it with film and non-woven fabric. In addition, the outside of the supporting rod of the rolling shutter door should be painted with antirust paint, and the top of the auxiliary rod should be sealed to prevent rainwater from entering and avoid danger in future use.

Step 3 protect the insulation quilt

When a typhoon comes, the insulation quilt is easily blown open by the wind or blown off the roof of the shed, and easily soaked by rain. Vegetable farmers should wrap a film on the outermost surface of the insulation quilt to ensure that there are no holes in the film to prevent moisture from entering the insulation quilt.
