In recent years, the number of species and populations of birds has increased sharply. At the same time, with the strengthening of orchard management, the quality of fruits has improved, and new varieties with bright colors, sweet taste, early maturity and late maturity have continuously appeared, which has also enhanced the temptation to birds. Especially exposed fruits are more vulnerable to bird attack. After the fruit is pecked and damaged by birds, the scars and residual fruits are everywhere, completely losing the commodity value, and causing further damage by diseases and insect pests. Bird damage has reached the point where it must be controlled. Here are five simple and effective ways to repel birds:
1. Fruit bagging
Fruit bags are the easiest way to prevent bird damage, and at the same time prevent the impact of pests, pesticides, dust, etc. on fruits. However, birds with big mouths such as magpies and crows can often peck through paper bags to eat fruits, and then those birds with small mouths such as sparrows will make things worse, and the fruits that have been eaten are extremely prone to pests and diseases in the area. Therefore, we must use good quality, tough and strong paper bags. Nylon wire mesh bags can be used for bagging in areas with many birds, which can not only prevent bird damage, but also not affect the color of the fruit, but the relative cost is relatively high. At the same time, bagging is only effective for grapes, apples, pears, etc., but not suitable for cherries, blueberries, etc.
2. Set up anti-bird nets
Anti-bird nets are suitable for both large-area orchards and small-area orchards. It is best to use yellow anti-bird nets in mountainous orchards, and red anti-bird nets in plain areas. These are the birds in mountainous areas and plains. The two most feared colors. In areas where hail occurs frequently, adjusting the size of the grid and combining the anti-hail net with the anti-bird net is a good measure to get twice the result with half the effort. However, the average cost per mu of bird-proof nets is high, and the service life is short. The fruit must be put away after harvesting every year, which is labor-intensive, and it is easy to age and crack when exposed to the hot sun and strong wind.
3. Improve cultivation methods
In areas where bird damage often occurs, properly retain more leaves, cover the fruit, and pay attention to the sanitary conditions around the orchard, which can also significantly reduce the occurrence of bird damage.
4. Other measures
According to the practical experience of fruit farmers, hanging some old CDs and small red flags in the orchard can also play a very good driving effect.
