Orchard repelling four measures

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 increased the temptation 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 Fruit ear bagging is the simplest way to prevent birds and birds, 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. Establishment of anti-bird nets The 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 plains use red anti-bird nets. The mountains and plains are the two most feared birds. 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. Each year, the fruit must be harvested after it is harvested, which is relatively time consuming. It is also prone to ageing and bursting when exposed to the sun and the wind.
3. To improve the cultivation method In the common areas of bird damage, appropriate retention of leaves, cover the ear, and pay attention to the health conditions around the orchard, can also significantly reduce the incidence of bird damage.
4. Other measures According to the actual experience of fruit growers, hanging some discs in the orchard, red flags, can also play a good driving effect.
