问:为什么浇水过多花卉会死亡? 山东袁晨答:这是因为浇水过多,使土壤长期处于水分饱和状态,土中空气被水代替,外部空气也不能进入,造成土壤缺氧,根的呼吸作用受阻,生理功能降低,根系吸水吸肥能力受阻。同时由于土壤缺氧,土中具有分解有机物功能的好气性细菌正常活动受阻,影 Q: Why flowers too much water will die? Shandong Yuan Chen A: This is because too much water, so that the soil is saturated with water for a long time, the soil air is replaced by water, outside air can not enter, resulting in soil hypoxia, The respiration of the root is blocked, the physiological function is reduced, and the ability of the root system to absorb water and absorb fat is blocked. At the same time due to soil hypoxia, the soil has the function of decomposing organic matter of aerobic bacteria blocked the normal activities,
