研究以南洋杉(Araucaria cunninghamii)为对象，以水培植株消毒液与生根诱导营养液为变量，研究其对南洋杉水培生根的影响，旨在探索出南洋杉水培诱导技术，为南洋杉的水培创新与出口应用等提供理论支撑与实践指导。试验分消毒与诱导水培生根两部分，并测定对比其生长量(平均新根数、生根率、水培根诱导率、新根平均长度、株高增长量等)。结果表明：南洋杉根系表面消毒的最佳方法为0.5%高锰酸钾处理20～30 min，或70%酒精浸泡60 s；水培根诱导的最佳培养液为观叶植物营养液+IBA 0.5 mg/L，或观叶植物营养液+NAA 0.5 mg/L。

In order to explore the hydroponics induction technology and provide theoretical support and practice guidance for hydroponics innovation and export ofAraucaria cunninghamii, the effects of disinfectant and rooting induction nutrition liquid on rooting ofA. Cunninghamiiwere studied. Experiment was divided into two parts as disinfection and hydroponics rooting induction. The mass growth average such as average number of new roots, rooting rate, hydroponics rooting induction rate, average length of new roots, plant height increment etc. were measured and compared. Results showed that: the optimal method of root surface sterilization forA. cunninghamiiwas soaking the roots in 0.5% Potassium Permanganate for 20~ 30 min or 70% alcohol for 60 s; the best hydroponics rooting induction liquid was foliage plant nutrient liquid plus IBA 0.5 mg/L, or foliage plant nutrient liquid plus NAA 0.5 mg/L.
