摘要
通过对北京地区7种野生景天对温度、水分、光照条件的适应性研究,表明野生景天在试验地能够完成发芽、展叶、开花、结实的生长发育过程;能通过扦插及分株方法繁殖;能忍耐的土壤最低含水量为3.7%～4.1%;耐42.2℃极端高温及-16.4℃的极端低温;能够在全光照及郁闭度为0.7的林下正常生长;绿期240～260d,是北京地区园林绿化的优良野生地被植物.
After the adjustability versus temperature moisture and sun＇s rays of 7 kinds of wild Sedum L. has been researched in Beijing area. This paper shows that, the wild Sedum L. can accomplish the upgrowth course of germinating, leaves open-outing, blossoming and fruiting in proving ground, can be bred via cutting and plant divided, can endure 3.7%-4.1% the lowest moisture, can endure 42.2℃ of the extremely highest the environment 240 to 260 days. temperature and -16.4℃ of the extremely lowest temperature, can grow normally under of complete sunlight or 0.7 canopy destiny, can last out green color for the period from They are excellent wild landscape plants for ground cover in Beijing area.
