健壮的杜鹃花,叶呈翠绿或墨绿色。如果叶色逐渐由绿转黄变白,同时叶片变小,叶缘向背后卷曲,很可能是由于莳养不当造成根部损伤引起的。杜鹃花喜肥,但忌施浓肥和未经发酵的生肥。如施肥过勤过浓,或施入生肥,就会灼伤根系。杜鹃花喜湿润,但忌积水和只湿表土的“跑马水”。如长期处于偏干或偏湿状态下,都会损伤根系。若发现上述叶色变化,可及时更换盆土,去除烂根,促发新根。
Sturdy azaleas, the leaves are green or dark green. If the leaf color gradually turns green from yellow to white, while the leaves become smaller, the curl edge to the back curly, it is likely due to improper maintenance caused by root damage. Azaleas like fat, but avoid fertilizers and unfermented fat. If too much fertilizer over fertilization, or into the fat, it will burn roots. Rhododendron hi moist, but avoid wet and wet topsoil “Happy Valley.” If long-term in the partial dry or partial wet state, will damage the root system. If you find the leaf color changes, timely replacement basin soil, remove rotten roots, promote new roots.
