盆栽花卉浇水过多，使土壤长期处于水分饱和状态，土中的空气被水占有，外部空气也不能进入，因而造成土壤缺氧，花卉的根系呼吸作用受到阻碍，生理功能降低ly根系吸水、吸肥能力减弱。同时，由于土壤缺乏氧气，土中具有分解有机物功能的好气性细菌正常活动也受到阻碍，影响矿? Potted flowers too much water, so that the soil is saturated with water for a long time, the air in the soil is occupied by water, outside air can not enter, resulting in soil hypoxia, flower root respiration is hindered, physiological functions reduce ly roots absorb water, Absorption capacity weakened. At the same time, due to the lack of oxygen in the soil, the normal activity of aerobic bacteria with the function of decomposing organic matter in the soil is also hindered, affecting the ore?
