摘　　要：在大棚内立体设施中 ,设置无土基质配方即 :砂 +砂、谷壳 +砂、树叶 +砂、锯末 +砂 4种处理 ,每基质分上、中、下布置 3个小区 ,研究 4种不同基质对半夏 (Pinelliaternate)主要农艺性状的影响。结果表明 :不同基质对半夏株高、珠芽及块茎鲜重的影响表现出显著或极显著差异 ;花序高度和百粒重存在量的不同。树叶 +砂配方有利于半夏植株、珠芽的生长 ,便于繁殖 ;锯末 +砂配方对增加半夏块茎鲜重最为适宜 ,有利于半夏产量的提高。The effects of different soilless media on principal agronomic traits of Pinellia ternate planted in vertical installations in greenhouse were researched. The soilless media used in the experiments were listed below: sand+ sand, husk+ sand, tree leaf+ sand, and sawdust+ sand. The four soilless media were regarded as four treatments, and every treatment was arranged to three small areas that were set vertically, i.e. upper, middle, and low layer. Results showed that the different treatments had significant influences (p<0.05) or extremely significant influences (p<0.01) on plant height, bulbil weight, and tuber weight. There were quantitative differences of plant inflorescence and hundred kernel weight. Tree leaf + sand medium could promote growth of stem and bulbil of P.ternate,promoting reproduction, and sawdust + sand medium was the most suitable for increase in fresh weight of tuber, promoting tuber yield of P.ternate.
