In recent years, the species and population of birds have increased dramatically; at the same time, with the strengthening of orchard management, the quality of fruits has increased, and the appearance of variegated, sweet, early-maturing and late-maturing new varieties has also enhanced the allure of birds. Especially exposed fruits are more vulnerable to birds. After the fruit is eaten and damaged by the bird, the wounds are scarred, the residual fruits are everywhere, the value of the commodity is completely lost, and the pests and diseases are further damaged. The harm of birds has reached the point of non-governance.
Here are five simple and effective methods of bird repellent:
1, fruit 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. But birds with large mouths, such as gray magpies and crows, can often break through paper bags to feed on fruits. Then those birds with small mouths, such as sparrows, add to the snow, and fruits that have been eaten are extremely prone to insect pests in the area. Therefore, we must use good quality, tough paper bags. Nylon wire 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, but it is relatively costly. At the same time, bagging can only be effective for grapes, apples, pears, etc., and it is not suitable for cherries, blueberries, etc.
2. Set up an anti-bird net
Anti-bird nets are applicable to large-scale orchards as well as small-scale orchards. In the mountainous orchards, it is best to use yellow anti-bird nets, and in the plains, red anti-bird nets are used. These are mountainous and plain birds. The two most feared colors. In regions 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. However, the average cost per acre of the anti-bird net is relatively large, and its service life is short. Every year after fruit harvesting, it must be collected and used. It is also more time consuming, and it is prone to ageing and bursting due to exposure to the hot sun and strong winds, especially at the beginning of this year. Anti-bird nets are damaged due to the collapse of heavy snow, and the loss is very high.
3. Add an isolation network
For certain fruits such as dried raisins, air inlets, vents, and vents, appropriate specifications of barbed wire and nylon mesh are set in advance to prevent birds from entering.
4, improve the 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.
5. According to the actual experience of fruit growers, hanging some discs in the orchard, red flags, can also play a good driving effect.
