Chinese. 以红茶花凤仙（Impatiensbalsamina）为材料，研究水培和不同配方基质对红茶花凤仙生长发育指标的影响，以便为其无土栽培提供科学依据。试验设置4个处理，分别为1:1、2:1、1:2体积比的椰糠：泥炭组合和水培，培养至3周、6周、9周时测定生长和开花数据。结果表明，1:2的椰糠:泥炭处理有利于叶数、开花数、叶重、茎重、花重、株重的增加；水培有利于株高和根重的增加，但是不利于开花；1:1和2:1的椰糠:泥炭组合的营养生长差，开花在4个处理中均处于中等水平。

In order to provide the scientific basis for its soilless culture, the effects of hydroponics and different stromas on growth and development of Impatiens balsamina were studied. The experiment was conducted in four different formulas: coconut husk: peat volume combinations of 1:1, 2:1 and 1:2and hydroponics. The growth and bloom of I. balsamina were determined after three, six and nine weeks. The result showed that coconut husk: peat volume combination of 1:2 was favorable for the leaf number, flower number, leaf weight, stem weight, flower weight and plant weight of I. balsamina, whereas hydroponics was favorable for its plant height and root weight, but was not for its bloom. The growth of I. balsamina was poor at stromas with coconut husk: peat volume combinations of 1:1 and 2:1, and their blooming abilities were medium among the four formulas.
