摘要(Abstract)：

以3 a生分根盆栽嘎拉苹果为试材,研究了不同根域交替灌溉不同水量对树体生长和水分利用效率的影响。结果表明,灌水量调控了苹果新梢二次生长的发生、生长时间和速率,每一根域每次灌水量为500 mL时,仅4/4根域灌水处理的新梢出现二次生长;灌水量为750 mL时,2/4、3/4和4/4根域灌水处理的新梢均出现二次生长;灌水量为1 000 mL时,1/4、2/4、3/4和4/4处理的新梢均有二次生长,其二次生长随着灌水根域的增多而时间提早,生长速率加快。每一根域灌水量相同时,植株主干、枝条、叶片、根系和总生物量随灌水根域增多而提高,750 mL与1 000mL根域灌水处理差异不显著。植株的水分利用效率随灌水根域的增多而降低。从确保树体正常生长和提高树体水分利用效率综合分析,2/4根域每次灌水750 mL为最佳灌溉方案。
