盆栽花木萎蔫的原因及防治

植物失水,细胞不能维持正常紧张所表现的症状叫做萎蔫。由于植物在吸收水的同时也在散失水(如蒸腾),当土壤的水势低于某一数值时,这种水的吸收和散失就不能平衡,散失的水分将多于吸收的水分,植物将失去膨压而发生萎蔫。此时若减少水的散失,水分又可达到新的平衡,因此植物膨压恢复,萎蔫现象消失。从光照、干旱、涝渍、温度、土壤、施肥和病虫害防治等方面来阐述导致盆栽花木萎蔫的原因,并提出相应的防治策落。

Potted Flowers Wilt Cause and Prevention

Plant water loss,cells are unable to maintain normal nervous symptoms exhibited by called wilting.Since the plant in absorbing water is also a loss of water (such as transpiration),when the soil water potential is lower than a certain value,the water absorption and dissipation can not balance,loss of water will be more than absorption of water,plants will lose turgor and wilted.If the reduction of loss of water,the water can reach a new equilibrium,therefore it is the plant of turgor pressure recovery,wilting phenomenon disappears.The author from the light,drought,waterlogging,temperature,soil,fertilization,pest control and so on to elaborate the cause of potted flowers and trees wilted,reason,and put forward the corresponding control strategy to fall.
