The anti bird net is suitable for both large and small orchards. It is better to use yellow net in mountainous area and red net in plain area. In areas with frequent hail, the grid size should be adjusted and the hail and bird prevention nets should be combined. However, the cost of bird proof net is high, and its service life is short. The fruit must be collected every year after harvest, which is labor-intensive. Moreover, it is easy to be aged and cracked by the hot sun and wind and rain erosion.
