飘移损失-
然而，与地面灌溉相比，喷灌过程中存在冠层截留和蒸发飘移损失，导致喷灌水的损失和水量的重新分配。
However , compared with surface irrigation , the water was intercepted by canopy , evaporation and excursion and causes the water loss and distribution during sprinkler irrigation .

喷灌的水分飘移蒸发损失可达总水量的20%～25%。
Floating and evaporation loss of sprinkler irrigation water could reach 20 ~ 25 % of the total .
