盆栽白鹤芋无土栽培技术研究.pdf

液浓度以2%o的质量分数、间隔15天施用一次肥料、搞底给液法时叶绿素含量最大。从白鹤芋的初花花期及花生长指标结果可以看出,白鹤芋的初花期与总叶面积有密切关系,在开花前期,总叶面积越大的处理组合初花期越早,说明白鹤芋生长到一定生长量后才开始开花,加快营养生长可促使白鹤芋提前开花。在营养液的使用中,采用本试验中的配比水平3:N:P:K:Ca:Mg:S=::::1:1、质量分数2%o、采用浇灌基质法、间隔15天施用一次肥料有助于自鹤芋花梗花苞质量的提高。[关键词]prehensivetechniquesincludingoptimumillumination,temperature,humidity,substrate,—year—,whichweresubstrate,ratioofnutritionelement,concentrationofnutrition,,humidityandilluminationweretested;Theheightofseeding,totalareasofleaves,numbersofleaves,photosyntheticrateandthecontentofchlorophyllweretestedinearlierseedlingsperiod,’,’m。’·m’2·s’-29℃,andtheappropriatehumiditywas60-80%.,use30%overshadowinthe3-5month,maduse70%overshadowandwinddrumtodecreasestemperature,‘andilluminationinlaterseedingstageandearlierbloomstage,:1perliteishelpfultotheheightofsee
