由于君子兰自身的生长特性,在南方正常生长时间较短。从育苗到成兰时间长一些是正常的,但南方夏季高温、高湿、干热风,还有一个温度高、湿度大、温差小、时间长的湿热霉变期,容易造成君子兰烂根、烂叶、抹头及发生病虫害等。而冬季又有一个较长的“零下”湿冷阶段,无暖气设施,若不注意保暖,君子兰极易发生冻伤、夹箭、不上箭、来年春夏烂叶烂心等问题。君子兰的生长环境和数量多少以人居环境而定。引发君子兰生病的病菌来源一是土壤,二是叶面感染,三是病株传 Clivia has its own growth characteristics and its normal growth time in the south is short. From the nursery to Cheng Lan a long time is normal, but the South summer high temperature, high humidity, dry hot air, there is a high temperature, humidity, temperature difference, a long period of hot and humid mildew, likely to cause the clivia rotten roots, rotten Leaves, wiping head and pests and diseases occur. In winter there is a longer “zero” wet and cold phase, no heating facilities, if you do not pay attention to keep warm, clivia prone to frostbite, clip arrows, not on the arrow, the next spring and summer rotten rotten and so on. Clivia growth of the environment and how much the number of living environment may be. First, the source of pathogens causing Clivia is soil, the second is foliar infection, and the third is disease transmission
