In summer and autumn, many fruits begin to mature. The harvest of fruits is hopeful for fruit growers. However, these fruits also attract various birds such as magpies, crows, sparrows, and pasqueflowers. They use sound, vision, physics, chemistry and other methods. Therefore, preventing or reducing bird activities in the orchard in advance is the most fundamental measure to prevent bird damage in the orchard. 1. Erection of anti-bird nets Anti-bird nets are not only suitable for large orchards, but also for small orchards. Due to the poor ability of birds to recognize light colors, the use of white and red materials allows the birds to clearly see the net and automatically retreat. In areas with frequent hail, adjusting the size of the grid and combining the anti-hail net with the anti-bird net is a good measure with half the effort. However, the cost of anti-bird nets is relatively high, and the average cost per mu increases by about 300 yuan. 2. The artificial bird-repellent birds pecking the fruit more severely in the early morning, noon, and dusk. Fruit growers can arrive at the orchard before this time and drive the birds out of the garden in time. However, the birds that are driven out of the park may come back again. Therefore, check and drive again after 15 minutes, and drive 3 to 5 times in each period. This method is more labor-intensive and suitable for orchards close to home and small planting areas. 3. Acoustic bird repellent Record the sound of firecrackers, eagles, and percussions with a tape recorder, and play loudly from time to time. You can also buy a professional intelligent voice bird repeller. Sound facilities should be placed around the orchard and at the entrance of birds to use wind direction and echo to increase the effectiveness of sound control facilities. Fourth, bird repellents have been used to repel birds in the past two years, and some areas have begun to use intelligent voice bird repellents. The intelligent voice bird repelling system can continuously and effectively achieve wide-area bird repelling in orchards, farmlands, and fish ponds. The maximum effective area can reach 3.3 hectares (50 acres). It has been successfully applied to cherries, medlars, and grapes. , Pears, apples, bayberry, millet and other crops, the effect of repelling birds is better. 5. Reflective film to drive birds The ground is covered with reflective film or the tree is hung with waste CDs. The reflected light can make the birds not dare to approach the fruit tree in a short time, and it is also conducive to the coloring of the fruit. 6. The main ingredient of chemical bird repellent is natural flavors. Hanging the bird repellent on an apple tree or spray diluted with water can slowly and persistently release a fragrance gas that affects the central nervous system of birds, making the birds produce A strong sense of discomfort and reluctance to approach the fruit tree or fly directly away from the orchard. The bird repellent can effectively drive away the birds, is green and environmentally friendly, and harmless to humans and animals. Remember to use the bird repellent produced by the regular manufacturer. 7. Mothballs to drive birds mainly use the special smell of mothballs to drive away birds. Generally, the smell of mothballs can last for about 15 days, which can prevent birds from approaching the fruit during this time. Choose high-quality mothballs with strong smell and hang them in the higher places of the fruit trees. Choose high-quality mothballs. Determine the quantity according to the size of the orchard. Wrap the mothballs into small packets with gauze, and place 3 to 4 capsules in each packet. When fruits such as pears, pears and grapes are about to mature, or after bagging the fruit to remove the fruit bag, hang it on the top of the tree. Generally, hang 1~2 bags per fruit tree to prevent bird damage. Disclaimer: Some articles on this website are transferred from the Internet.
