Abstract
The effects of different nitrogen forms on absorption and distribution of urea in peach were studied under bag-coated controlled release condition using the 15N trace technique.The results showed that the utilization rate of 15N was 13.81%,10.92%,15.53% and 15.78% respectively in four different treatments which were urea alone(T1),urea mixed with nitrate(T2),urea mixed with ammonia nitrogen(T3) and the mixed fertilizer of urea,nitrate and ammonia nitrogen at the ratio of 1∶1∶1(T4).The utilization rate of urea nitrogen could be increased significantly by T3 and T4 treatments,but decreased by T2 treatment.The distribution of 15N was higher in leaves than the other organs,accounting for over 60% of the total absorption.The rank of others was rootstrunksbranches.The total nitrogen absorption was the highest when urea mixed with ammonium nitrogen,but its apparent growth amount was lower than that of urea mixed with nitrate.
