摘　　要：采用静置水培法,使用4种不同的营养液配方,并以清水培养和椰糠基质栽培为对照,对巴西香蕉苗进行生长比较试验。结果表明:在香蕉苗增加的生物量方面,BXM配方(巴西木植物营养液)处理与椰糠栽培的差异不显著,但与日本园试配方、Hoagland植物营养液配方、1/2 MS培养基营养元素配方和清水培养的差异显著;在株高和叶面积方面,均以椰糠栽培的最大,BXM配方处理的居次,接下来依次是Hoagland植物营养液配方、日本园试配方、1/2 MS培养基配方和清水培养。综上所述,在这4种营养液配方中,BXM配方是巴西香蕉苗生长的最适营养液配方。In order to study water culture techniques, growths of the banana （Musa AAA cavendish subgroup cv. Brazil） plantlets under the static culture and substrate culture were ＇compared. Four nutrient solutions including Hoagland solution, Murashige and Skoog （1/2MS） solution, BXM solution and RSYY solution were used to culture banana plantlets, which grew in tap water or in substrate culture （pearlite as substrate）. The data showed that banana plantlets grew well in the four tested nutrient solutions, and there was a significant increase in biomass of the banana plantlets grew in static nutrient solution over that in tap water. Among the four nutrient solutions, the biomass of the banana plantlets that grew in BXM solution was next to that in substrate （pearlite） culture, and was significantly more than that in Hoagland solution, 1/2MS solution and RSYY solution. The indexes such as plant height and leaf area of banana plantlets that grew in BXM solution were largest among the four nutrient solutions, and then that grew in Hoagland solution, RSYY solution and MS solution reduced in turn. In conclusion, the banana plantlets grew best in BXM solution among the four nutrient solutions. So BXM solution is suggested, when growing banana plantlets in water culture.
