Even a double-layer paper bag covered with apples is difficult to prevent the damage of birds. Birds can pierce the paper bag and eat the fruit. During the coloring period after the apples are picked from the bag, the colors are bright and fragrant, and more birds will be attracted to eat the fruits.
According to experience, the damage to birds of fruit, bagged apple orchards is more serious than non-bag apple orchards, light fruits are more severe than shaded sunny slopes;
On the one hand, birds eat and damage fruits, and on the other hand, most birds are also important natural enemies of orchard and farmland pests. In one study, it was found that birds can eat up to 98 percent of codling moth larvae.
Therefore, while preventing and controlling bird damage, we must also pay attention to protecting these birds. It is recommended that orchards in various places adopt the following bird repelling methods according to their own conditions and local conditions:
Install bird nets.
The anti-bird net is suitable for both large-area orchards and small-area orchards. Due to the poor ability of birds to distinguish between light and color, white and red materials can be used, so that the birds can clearly see the net and retreat automatically.
In areas where hail occurs frequently, adjusting the size of the mesh and combining the anti-hail net with the anti-bird net is a good measure to get twice the result with half the effort.
