在冬春季节露地切花菊（Chrysanthemum morifolium Ramat．）栽培中，采用黑色地膜和反光地膜覆盖菊花垄，分别对营养生长期，生殖生长期及开花期切花菊主要观赏性状进行了测定，并就黑色地膜和反光地膜对菊花生长发育的影响进行了分析．结果表明，覆盖反光地膜对营养生长期、生殖生长期和开花期切花菊的株高、茎粗、花头质量、黄叶数量等主要观赏性状有显著（ P＜0.05）的提升作用，而黑色地膜则影响不明显．覆盖反光地膜有利于切花菊生产．%The black film and reflective film were used to mulch the ridge in open field of cut Chrysanthe-mum morifolium Ramat.production during winter to spring .The ornamental characteristics of cut chrys-anthemum in vegetative , reproductive periods and at flowering stage were investigated in order to study the effects of black film and reflective film mulching on the growth and development of chrysanthemum . The results showed that film mulching improved the ornamental characteristics of cut chrysanthemum such as plant height , shoot diameter , flower weight and number of yellow leave significantly ( P<0.05 ) , but the impact of black film isn't obvious .Reflective film mulching benefited the production of cut chrysan-themum.
