Preventing or mitigating the activities of birds in the vineyards is the most fundamental measure to prevent bird damage in vineyards. Currently, the bird-proof measures that are suitable for use in vineyards include: 1. Ears bagging. Ear bagging is the easiest way to prevent bird damage, and it also prevents the influence of pests, pesticides, and dust on the ear. However, larger birds such as gray magpies and crows are often able to break through paper bags to feed grapes. Therefore, good quality and tough paper bags must be used. Nylon mesh bags can be used for bagging in areas where there are many birds. This will not only prevent bird damage but will not affect fruit coloring. 2. Set up an anti-bird net. Firstly, a supporting net rack with 8-10-gauge wire mesh is added horizontally at 0.75-1m above the surface of the grapevine. A special bird net made of nylon yarn is laid on the net rack, and the ground is lowered around the perimeter of the grid and earth pressure is applied. In fact, to prevent birds from flying in from the side. Since most birds have poor resolution of dark colors, white nylon nets should be used as much as possible. Black or green nylon nets should not be used. In areas where hail is frequent, adjusting the size of the grid and combining the flood prevention net with the anti-bird net is a good measure to do more with less. 3. Add an isolation network. Prefabricated barbed wire and nylon nets shall be provided on air inlets, outlets, vents, and vents of raisins to prevent birds from entering. 4. Improve cultivation methods. In areas where there is frequent bird damage, proper conservation of leaves, cover of the ear, and attention to the health conditions around the orchard can also significantly reduce the occurrence of bird damage. frozen cutted swimming crab Delicious Swimming Crab,Fresh Delicious Swimming Crab,Frozen Cutted Swimming Crab,Fresh Frozen Cutted Swimming Crab Zhoushan Junwei Aquatic Products Co., Ltd. , https://www.junweiaquatic-intl.com
