摘要
通过对杨凌地区15a杂种马褂木的生长情况、观赏性、健康状况等因素调查,同时用多年来杨凌地区普遍栽植的七叶树、栾树作为对照,比较分析了杂种马褂木的适生性。结果表明:从前15a树木生长速度上看,杂种马褂木无论是直径、树高,还是冠幅、冠高,均是最大的,其次是栾树,第三是七叶树;从树木观赏性综合评价来看,杂种马褂木最受人们喜爱,得分数明显高于栾树和七叶树;从抗性表现来看,杂种马褂木健康性最好,几乎无病虫害,无冻裂和日灼现象,亦有极强的吸附二氧化硫、抗风、抗粉尘能力。相对而言七叶树病虫害较多,抗日灼能力较差。因此,杨凌地区乃至关中地区在今后的城乡绿化中可以适当扩大杂种马褂木的栽植规模。
By researching on hybrid tulip tree's growth,ornamentals and health condition and comparing with Koelreuteria paniculata and Horse chestnut in Yangling area,the adaptability of hybrid tulip tree gets comprehensively analyzed.The results showed that seeing from the past 15 years growing speed of those three trees,Liriodendron chinense×L.tulipifera ranks first no matter on diameter,height or crown span and crown height,Koelreuteria paniculata second and Horse chestnut the last.The ornamentals evaluation indicates that Liriodendron chinense×L, tulipifera was highly welcomed.The resistance ability investigation demonstrates that Liriodendron chinense×L. tulipifera owns the best health condition,nearly no insects or disease,frost crack or sun burn,at the same time it's able to greatly absorb sulfur dioxide,resists wind and stive,which Koelreuteria paniculata doesn't do well in.As the consequence,Liriodendron chinense×L.tulipifera growth should be expanded in Yangling for afforest purpose.
