火棘性喜光照。适应于大肥、大水,忌涝。能在温带亚热带气候条件下露地越冬。但其根系只能在短时间内承受低温(0℃以下),因而冬季易出现因根系受冻造成植株死亡。冻害当时表现并不明显,在开春后就会出现皮层内形成死亡,新芽枯萎,枝条缩水现象。冬季,因植物的生长处于相对休眠状态,水份的蒸腾量大大减少,如浇水过多,大量水份积在盆内,随着气温的变化,易造成盆内结冰,使植物死亡。因 Pyracantha hi light photo. Adapt to fat, flood, avoid floods. Can wintry in the temperate subtropical climate. However, its roots can only withstand low temperature (below 0 ℃) in a short time, so winter is easy to cause death due to freezing of roots. Frost damage was not obvious at that time, after the spring cortex will appear in the formation of death, withered sprouts, shrunken branches. Winter, due to plant growth in relative dormancy, greatly reduce the amount of water transpiration, such as excessive watering, a large amount of water plot in the basin, with the temperature changes, easy to cause the basin freezing, the plant died. because
