In the application of fruit tree bird prevention nets, special attention should be paid to these points!


At present, more than 98% of orchards have suffered from bird damage, and the annual economic loss caused by bird damage is as high as 700 million yuan. Scientists have found through years of research that birds have a certain sense of color, especially blue, orange-red and yellow. Therefore, on the basis of this research, the researchers invented a wire mesh made of polyethylene as the basic material, which covered the whole orchard and used it for apples, grapes, peaches, pears, cherries and other fruits, and achieved good results. Effect.
1. Color selection Generally, it is recommended to use yellow anti-bird nets in mountainous areas, and blue and orange-red anti-bird nets in plains. Birds in the above shades do not dare to approach, which can not only prevent birds from pecking fruits, but also prevent birds from hitting the nets. Anti-bird effect is obvious. It is recommended not to use transparent wire mesh in production. This type of mesh does not have a repelling effect, and birds are easy to hit the mesh.
2. The selection of mesh and net length depends on the size of the local bird. For example, small individual birds such as sparrows are mainly used, and 3 cm mesh bird-proof nets can be used; for example, magpies, turtledoves and other larger individual birds are the main ones. Optional 4.5cm mesh bird net. The bird-proof net generally has a wire diameter of 0.25 mm. The net length is purchased according to the actual orchard size. Most of the online products in the market are 100 to 150 meters long and 25 meters wide, so as to cover the entire orchard.
3. Selection of bracket height and density When installing the fruit tree anti-bird net, first lay the bracket. The bracket can be purchased as a finished bracket, or it can be welded by galvanized pipe, triangle iron, etc. The buried part should be welded with a cross to resist lodging. An iron ring is welded on the top of each bracket, and each bracket is connected with iron wire. After the bracket is laid, it should be firm and durable, and the height should be about 1.5 meters higher than the height of the fruit tree, so as 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 the support should be appropriately increased or decreased depending on the row spacing of the seed plants and the size of the orchard. The denser the better, but the higher the cost. Bird-proof nets of corresponding widths can be purchased according to the width to save materials.
Fourth, the erection of sky nets and side nets Fruit tree bird-proof nets should be erected three-dimensionally. The net on the upper part of the canopy is called the sky net. The sky net is worn on the iron wire drawn 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. The junction of the side net should be tight and 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 and causing damage.
5. The installation time is determined. The fruit tree anti-bird net is only used to prevent birds from harming the fruit and fruit. Generally, the fruit tree bird-proof net is installed 7 to 10 days before the fruit matures when the birds begin to peck and damage the fruit, and the fruit can be taken after the fruit is completely harvested. It can be stored under the condition to prevent aging from exposure in the field and affect the service life.
6. Maintenance and preservation of fruit tree bird-proof nets After installation, fruit tree bird-proof nets should be checked at any time, and any damages are found to be repaired in time. After the fruit is harvested, carefully remove the bird-proof net from the fruit tree and roll it up, pack it and store it in a cool and dry place. It can be used again when the fruit is ripe in the next year, generally it can be used for 3 to 5 years. The original text is transferred from the Agricultural Science and Technology Network
