In areas with many birds, nylon mesh bags can be used for bagging cards, which can prevent bird damage, but does not affect fruit coloring. It is also suitable for small vineyards or garden grapes. Vineyard, the method is to first add a support grid made of No. 8 to No. 10 iron wires vertically and horizontally on the surface of the grape rack at 0.75 to 1.0 meters.
A special grape bird-proof net made of nylon wire is laid on the mesh frame. The periphery of the mesh frame hangs down from the ground and is compacted with soil to prevent birds from flying into the future.
Since most of the birds are in the dark and chaotic, polyethylene mesh should be used, black or green PE mesh should not be used. The wire mesh mainly made of pe or nylon material has a small mesh, which effectively isolates the birds from escaping into the net and stealing the fruit.
This is the principle that the anti-bird net can prevent birds. The mesh of the bird-proof net is translucent, and the standard bird-proof net is colored because birds are wary of red, yellow, blue and other color contrasts. After the equipment, a red light or blue light appears above the field of the device, which makes the birds dare not approach, and can play a bird-proof effect without harming the birds, which is truly environmentally friendly and useful. Use blue or red anti-bird nets in plain areas.
The anti-bird net is mainly to intimidate the bird on the color, and the intention at the end is to make the bird not dare to approach the orchard and scare it thousands of miles away.
In terms of color, try to choose bright colors, which can attract the attention of the birds. Under the blowing of the gentle wind, the birds will naturally dare not care. Standard bird-proof nets are generally made of polyethylene mesh, but nowadays people choose different colors of bird-proof nets to keep birds away from the orchard.
