摘　　要：在大田相对自然状态下,对赣南脐橙进行了不同生长时期的非充分灌溉试验研究,结果表明:土壤水分过高或过低,均不利于赣南脐橙的生长发育及产量和品质的提高;赣南脐橙在萌芽期、枝梢生长期、开花期和果实生长期的最适土壤含水量分别为10.6%、10.6%、7.1%～10.6%和10.6%～14.1%,相当于田间持水量的41.7%、41.7%、28.0%～41.7%和41.7%～55.5%。Under the condition of close to the field,deficient irrigation experiments on navel orange in south of Jiangxi at different stages of its growth and development were conducted.The results showed that both high and low soil water content were unhelpful for the growth and development,yield and fruit quality of navel orange;the preferred soil water content in the period of germination,shoot growth,flowering and fruit growth was 10.6%,10.6%,7.1%～10.6% and 10.6%～14.1% respectively,which was equivalent to the field water-holding capacity 41.7%,41.7%,28.0%～41.7% and 41.7%～55.5% respectively.
