症状:斑点诊断:斑点可分多种:有细小而规则的,大而不规则的,也有湿而带疱的或者干燥而凹陷的,每种都影响叶的生长。很可能是栽培不得法引起,也可能是细菌或病毒感染的结果。小而扁平、略呈圆形的棕色斑点是最普遍的一种,常常因浇水或喷雾不当而引起。
Symptoms: Spots Diagnostic: Spots can be divided into multiple types: small and regular, large and irregular, also wet and blistery or dry and sunken, each affecting leaf growth. It is likely that the cultivation is not lawful, it may be the result of bacterial or viral infection. Small, flat, slightly rounded brown spots are one of the most common and often result from improper watering or spraying.
