In the summer and autumn, many fruits begin to mature. The harvest of fruits is hopeful for fruit growers, but these fruits also attract various birds such as magpies, crows, sparrows, and pasqueflowers, using sound, visual, physical, and chemical methods. Therefore, preventing or reducing the activities of birds in the orchard in advance is the most fundamental measure to prevent bird damage in the orchard.
this are not only suitable for large-area orchards, but also for small-area orchards. Because birds have poor ability to recognize light colors, it is best to use white and red materials so that the birds can see clearly that there is a net and automatically retreat.

Record the sound of firecrackers, eagles, and percussions with a tape recorder, and play them at high volume 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.
In the past two years, 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, grapes, pears, apples, etc. On bayberry, millet and other crops, the effect of repelling birds is better.
Cover the orchard ground with reflective film or hang old discs on the trees. The reflected light can make the birds not dare to approach the fruit trees in a short time, and it is also conducive to the coloring of the fruit.
Hanging the bird repellent on the apple tree or spraying diluted with water can slowly and persistently release a kind of fragrance gas that affects the central nervous system of birds and make the birds produce Strong sense of discomfort and reluctance to approach the fruit tree or fly directly away from 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, grapes and so on 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 packets per fruit tree to achieve the purpose of preventing bird damage.
