There are many birds common in the vineyards. In the south,, bald-headed puffins and other birds have a greater influence on grapes. In the north, sparrows and grey magpies are the most important birds that harm grapes. Vineyard bird hazards mainly refer to the loss of yield or quality caused by eating and pecking fruit, while the damage of pecking fruit is conducive to the reproduction of pathogens, making many normal fruits vulnerable. At the same time, birds peck at young shoots, petals, buds and trample on grafted branches in the spring, causing huge economic losses to fruit tree production. Here are some of the prevention and control measures for bird injuries that I hope will help you.
1. Fruit spike bagging
Bagging is one of the easiest ways to prevent birds, pests, pesticides, dust, etc. from affecting the fruit. Nylon mesh bags can be used for bagging in areas with more birds, as larger birds such as grey birds and crows can usually peck at paper bags for grapes. Nylon mesh bagging not only prevents bird infestations, but also does not affect fruit coloring.
2. Scarecrow drives birds
Placed scarecrows in the garden, birds have good vision and are more sensitive to the presence of natural enemies.
Disadvantages: Scarecrow has a long history, birds have long been accustomed to it, no longer afraid, if you want to completely expel birds, you must make the scarecrow more realistic.
3. Sound bird repellent
The sound of high-decibel firecrackers, eagles, knocks and the angry sounds of predators are recorded with a tape recorder, and repeatedly played in large volumes in the orchard to disperse the birds at any time, paying attention to changing them every once in a while.
4. Pull the bird repellent belt
This control method has been applied to farmers in Binchuan New Town, Qiaodian and other places. The advantages of this method: low cost, saving manpower and time; after the wind blows, the sound is larger, and the free manual bird repellent effect is better. Birds do not react visually as well as to sound, so visual bird repellents are best used in combination with sound repellents for better control.
5. Use reflective film to drive birds
Laying reflective film in the open space between rows, hanging colored reflective strips or waste discs and other items that reflect light in areas where bird infestation is more serious, can stimulate the vision of harmful birds, so that they no longer dare to approach, and play the purpose of driving birds.
6. Rack anti-bird net
Bird net is a very effective bird control tool, compared to other bird control tools, it does not harm birds, and the effect is good, cost-effective. When using anti-bird nets, we should pay attention to the choice of mesh holes, different birds are suitable for different mesh sizes, and attention should be paid to specifications when choosing anti-bird nets. The establishment of a protective net in the fruit ripening season can prevent bird infestation, and in the fruit tree growth season, it can also prevent strong convective weather hazards such as hail and wind, and can even play a role in sunburn and insect prevention, which is a lot of measures.
Disadvantages: Anti-bird NetEase aging, but also need to consume a certain amount of man-hours of maintenance.
7. Artificial bird repellent
Usually, birds are more frequent in the early morning, noon, and dusk. Fruit grower friends can rush to the orchard for artificial bird driving during these three periods. This is a more time-consuming and laborious measure, because the birds that are driven will come back. It is more suitable for close and small orchards.
It is important to remember that birds are protected as an important part of nature, and are also friends of humans, an important part of the natural ecosystem on which humans live.
