摘要: 研究了生长介质中起始肥料对一品红生长的影响和一品红不同部位矿质养分含量。结果表明:
速效肥比缓效肥更有利于一品红生长并提高品质,速效肥中供试的两种NO3--N与NH4+-N比例对一品红生长影响不大。绿色叶片矿质养分含量,除Fe和Mn较高外,与国外推荐的养分诊断指标相一致,说明目前国外推荐的一品红养分诊断部位适合于绿色叶片。

关键词: 一品红, 起始肥料, 生长介质, 矿质元素

Abstract: This study examined the efects of various start fertilizers on poinsettia growth and nutritional status in different portions of poinsettia.Results of the study show more favorable growth and higher quality of poinsettia grown in fast-release-fertilizer (FRF) than in slow-release-fertilizer (SRF).The ratio of NO3--N
and NH4+-N in FRF did not significantly affect the growth of poinsettia. Concentrations of N,P,K,Ca,Mg, Cu and Zn in green leaves were comparable to the recommended standards while Fe and Mn concentrations exceeded the levels.

Key words: Poinsettia(Euphorbia pulcherrima Willd), Start fertilizer, Growing medium, Mineral element
