浇花用的水,应当是洁净、中性的软水,但一般情况下我们只能利用自然水源,即河塘水、自来水等,这些水浇花通常并不很好,如有些水混浊、含有氯气、碱性过大等,这就有必要对水质加以改良。下面介绍几种常用的处理方法:净化河塘中的水,往往含有大量的泥沙及有机杂质颗粒而显得混浊,用这样的水浇灌花卉,会污染枝叶,破坏土壤的通气性,阻塞毛细孔道,影响根系的呼吸,因此必须作净化处理。最简单的净化方法是将待处理水置于大缸中,加入少量明矾[ALK(SO_4)_2·12H_2O]并充分搅动,溶解后,静置一段时间,水中的杂质就会形成絮状沉淀积于缸底,上层的澄清液即可用来浇花。活化井水、泉水、自来水等不宜直接用来浇花,这是由于这些水源的温
Water used for watering flowers should be clean, neutral soft water, but under normal circumstances we can only use natural water, that is, river water, tap water, etc., these watering flowers are usually not very good, if some water turbidity contains Chlorine, alkaline too large, it is necessary to improve the water quality. Here are some common methods of treatment: purifying water in rivers and lakes, often containing large amounts of sediment and organic impurities particles appear turbid, watering flowers with such water will pollute the branches and leaves, damage the soil aeration, blocking the capillary channel , Affect the respiratory root, it must be purified. The simplest purification method is to place the water to be treated in a vat. Add a small amount of alum [ALK (SO_4) _2 · 12H_2O] and stir it thoroughly. After standing for a period of time, the impurities in the water will form a flocculent sediment At the bottom of the cylinder, the supernatant can be used for watering the upper layer. Activate well water, spring water, tap water, etc. should not be used directly to water the flowers, which is due to the temperature of these water sources
