摘要: 采用发达国家已经大量应用的潮水式(Ebb&Flow)底面灌施营养液栽培系统,以盆栽杜鹃
品种‘Mission Bell’作为试材,筛选出适合杜鹃盆花无土栽培 基质配方。混有草炭的M1(体积比:草炭土3+蛭石3+珍珠岩3)、M2(草炭土3+蛭石3+砻糠3)和M4(草炭土2+蛭石2+珍珠岩2+著糠2+腐叶土2)基质配方栽培的植株表现较好,尤以M1处理,即‘草炭土3+蛭石3+珍珠岩3’的等量配方为最优,而椰壳并不适合盆栽杜鹃的植株生长。土壤的理化分析和植物体分析结果表明,营养液灌溉处理后基质的pH值基本相同,但EC值的增幅很大,是由封闭系统内营养液中盐分累积所致;盆内基质中的矿质营养元素和阳离子交换量也明显增加;植物体的营养元素含量水平普遍较高,非常符合杜鹃类植物的生长条件与特殊需求。

Abstract: The experiment concerned the 3 years.old plants of pot azalea (Rhododendron simsii ‘Mission Bell’)were designed as 30 replicates to conduct studies on media formula with hydroponics.In terms of plant height and width,leaf length and width,fresh and dry mass,root development and leaf chlorophyll content(SCDSV),the results indicated that M 1(Peat moss 3+Vermiculite 3+Perlite 3 by volume)formula was the best media for soilless culture of pot azalea plants.the medium formula containing coconut was
not suitable for soilless azalea culture. By analyzing physical and chemical properties of different media formu1a before and after subirrigation with Sonneveld nutrient was found that pH values tended to 5 and
EC values increased a lots as a result of salt accumulation in media at a closed system of hydroponics:all the contents of total N, available P,K,Ca, Mg,and CEC in 5 media form ula increased as wel1. Finally,contents of macronutrients and concentrations of micronutrient in plants of ‘Mission Bell’were almost around the optimal levels of plant growth.
