浇水是花木管理的重要环节,也是花木种植成败的关键。浇水过多、过勤,会使植株根系缺氧产生呼吸困难,代谢功能降低,吸水肥能力减弱,导致窒息烂根,叶子发黄,甚至死亡。浇水过少,根部吸收的水分少于叶面蒸发量,易引起植株生理缺水,植株的正常的生理活动受阻,严重者造成萎蔫枯死。浇水的时间及浇水的方式方法不妥,也会影响植株的生长速度和开花效果。因此,科学浇水十分重要。 Watering is an important part of the management of flowers and trees, but also the key to the success of flowers and trees. Watering too much, too often, will plant roots hypoxia dyspnea, reduced metabolic function, decreased ability to absorb water, leading to suffocation rotten roots, yellow leaves, and even death. Watering is too small, the root absorbs less moisture than the leaf surface evaporation, easy to cause plant physiological water shortage, the normal physiological activity of the plant blocked, resulting in serious wilting dead. Watering time and watering method is not proper, will also affect the plant growth rate and flowering effect. Therefore, scientific watering is very important.
