美国科罗拉多(Colorado)州和爱达荷(Idaho)州的一些植物生理学家和农业工程师,将测量植物气孔的技术和电子技术结合起来,形成一套由电脑控制的灌溉系统。原理是植物根据细胞膨压的变化,向灌溉系统发出需水的信号,相联结的水泵就开始浇灌。这种情形正如同孩子啼哭要水喝一样。气孔测量计钳在植物的叶子上,一个很敏感的电极与之相连。关于植物细胞 Some plant physiologists and agricultural engineers in the states of Colorado and Idaho, in the United States, combined the technique of measuring stomata with electronics to create a computer-controlled irrigation system. The principle is the plant according to the changes in cell turgor, issued to the irrigation system water demand signals, the associated pump began to irrigate. This situation is just like children cry to drink the same water. Stomatometers clamp the leaves of plants and a very sensitive electrode is attached to them. About plant cells
