Spring planting and autumn harvest, autumn is the season of fragrant fruits, but also the season when birds start to destroy the orchard. Soon to be ripe fruits emit a tempting sweet smell, the whole orchard is like a big perfume bottle with a lot of fragrance, birds gather ready to go, salivating waiting for the arrival of the ripening period, in one fell swoop.
Since ancient times, agricultural production has been struggling with birds, especially on a large scale. For example: an acre of crops is easier to control bird damage, sitting on the ground from time to time knocking the washing basin, put a cannonball can scare away birds, over and over again, really can not get a bamboo pole shouting rushed into the flock of birds is also very effective. What about ten acres, a hundred acres, thousands of acres?
There are several good methods for repelling birds in crops, including shape repelling method, sound and light repelling method, taste repelling method, color repelling method, protective net repelling method, and specialized bird repelling device repelling method.
1. Shape driving method: The most common method is the scarecrow driving birds. Crops are afraid of birds, but the birds are most afraid of humans. They pass through the air and find delicious food in the field. They just want to dive straight down, and when they see someone in the field, they quickly turn around and evacuate. However, birds also have intelligence. Although they are very low, they find that the scarecrow always stands there and does not pose a threat to them, which makes it easy for them to lose their effectiveness, I have even seen scenes where some timid birds are still resting on the shoulders of the scarecrow.
2. Sound and optical drive driving method: The sound of driving away birds or other sounds that birds fear can be played in the field through recording equipment, which can indeed have some effects, and even farmers can make them out of broken glass; Wind chimes", Hanging in the field with a clanging sound also has a certain effect on driving away birds. Some people purchase reflective tapes, CDs, etc., and use the characteristic of constantly shaking the reflection in the sunlight to stimulate the eyes and scare the hearts of birds, so they naturally dare not approach.
3. Flavor bird repellent method: Some bird repellents sold in the market today, such as various components such as cinnamamide and camphor oil, as well as their mixtures, are safe for birds and do not cause harm to birds. They have become a favorite in the bird repellent market for a while. However, the shelf life is too short, and the effective one is one week. To solve this problem, the concentration and usage of bird repellents can only be increased, And these have caused a significant increase in costs, which is difficult for farmers to accept.
4. Color bird repellent method: Many birds are afraid of red, especially for seeds sown in the field. By coating them with seed coating agents (most of which have a red warning color), the problem of bird damage can be reduced.
5. Protective net bird repelling method: This is not called bird repelling, it should be considered as bird prevention. Although it is bulky, it is very effective. In some economically valuable fruits and vegetables, growers generally choose the method of protecting crops with protective nets. Although the cost is high, it is once and for all, saving a lot of trivial work, and can devote all the energy freed up to field management.
