不同基质对郁金香切花主要性状的影响

目的]探索栽培基质对郁金香切花主要外观品质的影响。方法]以菜园土、草炭及珍珠岩等基质为试材,按单一或不同比例进行混合配制成7种栽培基质,研究不同栽培基质对郁金香切花茎高、茎粗及花朵纵径等主要性状的影响。结果]在菜园土∶草炭=1∶1基质中郁金香花茎最长、茎最粗,分别达53.78和0.95 cm,在菜园土∶珍珠岩∶草炭=1∶1∶1的基质中郁金香花朵纵径最长,为7.91 cm。结论]在7种栽培基质中,以菜园土∶草碳土=1∶1为栽培基质较好,可以在连云港市推广使用。

Effects of Different Substrates on Main Characters of Tulipa gesneriana

Objective]In order to investigate the effects of different substrates on main characters of Tulipa gesneriana.Method] Tested sub-strates materials such as garden soil ,peat and perlite were mixed into seven kinds of culture substrates by single substrate or several substrates in different proportions.Furthermore,the effects of seven culture substrates on main characters including stem height ,stem diameter and floral longi-tudinal diameter of Tulipa gesneriana were studied. Result] The results showed that Tulipa gesneriana cultivated in garden soil ∶peat =1∶1 got the maximums of stem height(53.78 cm) and stem diameter(0.95 cm),and cultivated in garden soil ∶perlite∶peat =1∶1∶1 got the longest flo-ral longitudinal diameter(7.91 cm).Conclusion] Comprehensive analysis results suggest that the mixed substrate(soil∶peat=1∶1) is the opti-mal growing medium for Tulipa gesneriana cultivation,and can be widely used in Lianyungang.
