Depending on the size of the local bird, such as small individual birds such as sparrows, 3 cm mesh anti-bird nets can be selected; for large individual birds such as magpies and turtle doves, 4.5 cm mesh anti-birds can be selected network. Anti-bird nets generally have a wire diameter of 0.25 mm. The net length is purchased according to the actual orchard size. The length of Internet products in the market is about 100 to 150 meters long and about 25 meters wide. It is better to cover the entire orchard.
When installing the anti-bird nets for fruit trees, a bracket must be laid first. The bracket can be purchased as a finished bracket or welded with galvanized pipe or triangular iron. The buried part should be welded with a cross to prevent lodging. An iron ring is welded on the top of each bracket, and the wires are connected to each bracket. After the support is laid, it should be strong and durable, and the height should be about 1.5 meters higher than the height of the fruit tree to facilitate ventilation and light transmission. The density of the bracket is generally 5 meters in length and 5 meters in width. The density of scaffolds increases or decreases depending on the row spacing of the plant and the size of the orchard. The denser the better, but the denser the higher the cost. Bird-proof nets with corresponding widths can be purchased by width to save materials.
Fruit tree anti-bird nets must be erected three-dimensionally. The net in the upper part of the tree crown is called sky net. The sky net is worn on the drawn wire on the top of the bracket. Pay attention to the junction to be tight and leave no gaps. The outer net of the canopy is called the side net, and the junction of the side net should be tight, the length should reach the ground without leaving any gaps. The sky net and the side net are closely connected to prevent birds from entering the orchard.
The bird-proof nets for fruit trees are only used to prevent birds from harming fruit fruits. Generally, the birds-proof nets are installed when the birds start to peck 7 to 10 days before the fruit matures. After the fruits are completely harvested, they can be removed and stored. Field exposure ages and affects service life.
Fruit tree anti-bird nets were inspected at any time after installation, and any damage was found and repaired in time. After the fruit is harvested, carefully remove the fruit tree anti-bird net and roll it up. Pack it and store it in a cool and dry place. When the fruit matures in the next year, it can be used for 3 to 5 years.
