水是花卉细胞的主要组成部分,也是花卉进行光合作用的主要原料之一。活的花卉鲜重的75～90％是水分。土壤中的营养物质,只有溶解于水时才能被花卉吸收。总之,没有水,花卉就无法生存。花卉需要的水分,主要依靠根毛从土壤中吸收,再传到花卉体内各个部位,供生长发育的需要。花卉对水的需要量和它的原产地水分条件有关。原产于热带的花卉需水量较多,原产干旱地区的需水量较少。叶子大、质地柔软、光滑无毛的花卉需水量多;叶子小、质地硬
Water is a major component of flower cells and one of the major raw materials for photosynthesis of flowers. 75 ~ 90% of fresh flowers are fresh water. Soil nutrients, only when dissolved in water can be absorbed by the flowers. In short, flowers can not survive without water. The water that the flower needs, mainly relies on root hair to absorb from the soil, and then spread to various parts of the flower body for the needs of growth and development. Flower water demand and its origin of water conditions. Originated in the tropical flowers require more water, arid areas of origin demand less water. Large leaves, soft texture, smooth hairless flowers require more water; leaves small, hard texture
