- Abstract:
- This study aimed at the airflow variation of an orchard on reclaimed land from riverbed in the East Rift Valley of Eastern Taiwan. The experimental site was a sugar apple orchard with area of 32 000 m2 and reclaimed from the riverbed of Luye River, located in Luye Hsiang, Taitung Hsien, Taiwan, near to southern East Rift Valley. The anemometers with 2.5 m and 6 m height above ground surface were set on the observational tower which had been set in middle side of the experimental orchard from November, 2007 to January, 2010. The mean height of sugar apple tree canopy was 2.2 m and the age was over 5 years. The results had summarized as, the hourly mean wind speed was close to zero twice a day, and it could be easily to distinguish the wind field variation of daytime (7:00 am—7:00 pm) and 8:00 pm—6:00 am). The north strong breeze inlet the southern East Rift valley could result in the wind speed in apparent increasing tendency with one hour, then the wind speed above fruit tree canopy with 0.3 m height was over 3.8 m/s. The strong breeze continually swayed the fruitage would result in the frictional damage and that was harmful for fruit tree growth.
