	%X Repeated additions of the unfertilized bacteria led to
increase the activity of Nitrogen-fixing bacteria in the root zone with
drip irrigation system compared to traditional manual vaccination to
increase the proportion of Nitrogen from 29% to 64%, and the
efficiency of adding Nitrogen fertilizer did not exceed 9.5% while
dropped to 4%, due to the amount of fertilizer added was not exceed
20kg N/h, and the second was the existence of a large amount of
available Nitrogen in the soil by fixation, while the efficiency of
irrigation system between 2.08 to 2.26 kg/m3.
