摘要：以茶花Camellia japonica3个品种黑魔法C.japonica‘Black Magic’,新查理斯顿小姐C.japonica‘Miss Charleston Variegated’,大海伦C.japonica‘Helen Bower’的2年生扦插苗为试材,将珍珠岩、泥炭、椰糠、河沙、腐熟木屑和煤渣等按不同体积比配制成7个栽培基质配方,以菜园土为对照,研究不同基质配方对山茶生长及生理特性的影响,结合基质理化性质分析,筛选茶花最佳栽培基质配方。结果表明,在珍珠岩∶泥炭=2∶1的基质上栽培的茶花品种株高、地径和冠幅等分别比对照高34.3%～42.9%,17.2%～26.0%,11.3%～32.9%;根系活力、叶片的可溶性糖和叶绿素质量分数最高值分别为133.90mg·g-1·h-1,22.7g·kg-1和2.48mg·g-1,均显著高于对照;其容重、总孔隙度、电导率和盐基交换量分别为0.20g·mL-1,73.00%,67mS·m-1和81.2cmol·kg-1,均符合无土栽培要求,有效矿质养分质量分数较高,因此,可以作为茶花无土栽培基质应用推广。
This experiment was conducted to select the optimnm medium formula for a culture of Camellia japonica. Formulas were mixed with seven volume proportions of perlite, peat, coir fiber, sand, decomposed sawdust, and coal cinders. Bare soil was used as a control, and 2-year-old cuttings of C. japonica seedlings（＇Black Magic＇, ＇Miss Charleston Variegated＇ and ＇Helen Bower＇ ） were chosen as the planting material. In terms of plant height, trunk diameter, crown breadth, leaf width, root activity, leaf chlorophyll content, and soluble carbohydrate content, the results showed that perlite ： peat = 2 ： 1 was the best media formula for this soil-less culture. Compared with bare soil, C. japonica in the best media had greater plant height （34.3% - 42.9%）, trunk diameter （17.2% - 26.0%）, and crown breadth （11.3% - 32.9% ）. In addition, chlorophyll content, root activity, and the soluble carbohydrate content were significantly（P〈0.05） better than the control with maximums of 2.48 mg·g^-1 133.90 mg·g^-1·h^-1, and 22.7 g·kg^-1, respectively. Also, physical and chemical properties, such as volume-weight（0.20 g·mL^-1）, porosity （73.00%）, electric conductivity value （67 mS· m^-1）, and salt-base exchange （81.2 cmol·kg^-1） were suitable for C. japonica cultivation.
