摘要
以美国泛美公司的大红品种（梦幻3113）为材料，研究了我国多年经验模式和美国维生模式下矮牵牛穴盘苗生长状况。结果表明，维生模式下穴盘苗生长发育比经验模式发育提前2片叶左右，生物量为经验模式的3～5倍，根系干重、根长和根系活力均显著高于国产栽培方式，但叶片光合速率和叶绿素含量在同一苗期无显著差异。2种栽培模式造成植株体内的大量元素含量差畀显著，基质内的养分供应是造成不同栽培模式下矮牵牛穴盘苗生长发育差异的直接原因。
The cultivation models were studied with petunia plug seedlings（Dreams 3113）. The result showed, the plug in the SPEEDLING model grow about two leaves ahead of the traditional model, and it＇s biornass is about 3 to 5 times more than the latter. The root dry weight, length and the root vitality are higher than that of the traditional modol , but there is no signal difference between them in the same development term. The nutrients in the substrate is the main reason that cause the difference between two cultural models.
