1、不同基质对盆栽杜鹃花生长的影响张杰黄里华顾海燕张春英上海植物园/上海城市植物资源幵发应用工程技术研宄中心上海市园林科学规划研究院/上海城市困难立地绿化工程技术研宄中心为废弃物在杜鹃花栽培基质中的循环利用提供技术依据，对降低生产成本和废弃物资源化循环利用方面有重大意义。用有机基质枯枝落叶发酵产品、草炭、松树皮、椰糠和无机基质珍珠岩、黄沙、原土等材料配成9种栽培基质，测定在不同配比栽培基质屮杜鹃花的生长指标(株高、冠幅、分枝数、叶面积、叶绿素)，并进行方差分析。结果表明，A3、么基质株高较好，冠幅、分枝数最优，株型丰满，叶绿素含量高，
2、叶面积大，植株生长势健壮，整体生长指标优良。综合各项指标分析，草炭:椰糠:枯枝落叶:珍珠岩=6:3:3:1和草炭:枯枝落叶:黄沙=2:2:1配比的栽培基质较适合于盆栽杜鹃花的生长。关键词：杜鹃花;栽培基质;生长指标;通信地址300231上海市龙吴路1111号上海植物园科研中心，Tel:021-54363369-1012,R-mail:496494237@qq.como通信地址400231上海市龙吴路1111号上海植物园科研中心，Tel:021-54363369-1056，。基金：上海市科学技术委员会“科技创新行动计划”农业领域科研
