鲜花虽不能永存,但可设法使其延寿。请诸君一试。1.水中剪切法:所有的植物,在它的根茎里均排列着密密麻麻海绵状的吸水小孔,虽不能与人身动静脉相比,也有类似的功能。植物的生长均要靠它(小孔)来输送水分和养料。当我们拿过一枝花枝,根据所需长短,剪去多余部分时,空气就会乘虚进入根茎小孔。当你再把花枝插入水中,小孔中的输送小 Although flowers can not last forever, they can try to extend their life. Please try it. 1. Water shear method: All plants, which are arranged in its rhizome dense spongy sponge-like pores, although not with human arteriovenous, also have similar functions. Plant growth depends on it (holes) to transport moisture and nutrients. When we take a flowering branch, according to the required length, cut off the excess part, the air will take advantage of access to rhizome holes. When you put the flowering branches into the water, the small hole in the delivery
