大部分植物重量的85％-95％都是由水组成的,这些水几乎都是从土壤或基质中获得,因此合理灌溉是使植物健康生长的基本条件之一。缺水和过量灌溉对植物具有同等的危害。植物在湿度不佳的基质中长期生长,根系就不能健康生长。根系不能健康生长将导致植物发黄凋萎,叶片顶部和边缘变成褐色,叶片坠落、枝条死亡。
85% -95% of the weight of most plants consists of water, almost all of which is derived from soils or matrices. Therefore, proper irrigation is one of the basic conditions for the healthy growth of plants. Water scarcity and excessive irrigation have the same harm to plants. Long-term plant growth in poorly-conditioned matrices does not allow healthy root growth. The inability of healthy roots to grow will result in yellowing of the plants, browning of the top and margins of the leaves, the fall of the leaves and the death of the shoots.
