用水以选用凉开水为宜。因为自来水煮沸后,里面的氯气会挥发干净,腐酸细菌被杀灭,有害矿物质也大都沉淀淘汰,水分子结构的排列近似于植物细胞内水分子的结构顺序,提高了水的活性,因而容易被插枝吸收。在不需要任何生根激素和不加入营养物质的情况下,插枝生根良好。水养过程中可每隔4～5天换一次水。容器宜选用口小底大的容器。因为口小的容器可以借助药棉固定插枝,使插枝下端伤口悬挂于容器水中央,有利于新生根系充分舒展。同时塞好药棉后可使插枝中部处于湿度较大的水气环境中,既减少插枝水分蒸发,又使水气通过皮孔内渗,利于插枝所带绿叶的保 Water to use cold water is appropriate. Because the tap water after boiling, the inside of the volatile chlorine will be clean, humic acid bacteria are killed, most of the harmful minerals are precipitated out, the arrangement of water molecules close to the structural order of water molecules in plant cells, increasing water activity, and thus Easily absorbed by cuttings. In the absence of any rooting hormone and without the addition of nutrients, cuttings rooting well. Watering process can be changed every 4 to 5 days water. Container should be used big mouth small mouth container. Because the mouth of the small container can be fixed with cotton wool cuttings, cuttings at the bottom of the wound hanging in the water container is conducive to the full rejuvenation of the root system. At the same time stuffed cotton can make the middle of the cuttings in the humidity of the water vapor environment, not only reduce the evaporation of cuttings, but also to make water vapor through the perforation of the skin, which will help cuttings with green leaves
