摘　　要：基于盆栽试验,研究了不同深度滴灌对植株膜伤害和抗氧化酶的影响。结果表明,自然干旱和2/3土层灌水处理叶片丙二醛和抗氧化酶活性较高,植株受旱;2/3土层供水、1/3土层供水和表层供水叶片丙二醛和抗氧化酶活性较自然干旱低,植株生长较好;同一处理灌水根区域的根系抗氧化酶活性较低。适宜苹果幼苗生长的灌水处理为表层供水和1/3土层供水。Based on pot experiments, the effects of drip irrigation in different depths on the membrane injury and antioxidase system were studied. The results showed that： the malondialdehyde content and the antioxidant enzymes aelivity in the treatments of drought and two-thirds of soil water supply drip irrigation were higher than other treatments,which were not conductive to the growth of plant. So, surface drip irrigation and a third soil water supply were more adaptable to young apple trees.
