Ezperimental Research on Sprinkler Irrigation Evaporation and Drift Losses in Arid Sandstorm Regions
Base on experiment and analysis on sprinkler irrigation evaporation and drift losses(SIEDL) in Gansu province, the author drew some conclusions: (1)when average wind speed was during the range of 0～3.4m/s, the SIEDL was 5.6%～15.6%; (2)the main influence factor on the SIEDL was the average wind speed, then was the average temperature, the last one was the average relative humidity;(3)when the average wind speed was below 4.7m/s, the spray water utilization coefficient could get to upward of 0.8, which could satisfy the water need of the crop. The experimental results accorded with the mostly domestic and overseas research works, and also accorded with the 《Technical Standard for Sprinkler Irrigation Engineering》.
