在春季和夏季，在户外销售区域的集装箱厂维持适当的水。在大众营销领域，员工对各种环境条件下植物的水需求不知情。植物经常受到严重压力，并在所有质量下降。开发了一个系统，以在户外销售区域自动灌溉集装箱设备。该系统是在大学中开发的受控水位（CWT）灌溉系统的修改。肯塔基州（U.K.）。销售区域由2个架子组成，每个架子长2.44米，宽0.28米。槽由5厘米直径的管材构造，具有1/4槽;它附着在架子的背面。毛细管的一侧放在架子上，悬浮在含水的槽中。 Two systems were used to maintain the level of water in the trough. One was a small float valve installed in a 10-cm PVC pipe which was attached to the 5-cm PVC pipe. The float was adjusted to maintain the water in the trough 2 cm below the top of the shelf. The water reservoir consisted of a 20-cm diameter PVC pipe, 1.22 m long that held 70 L of water. A second system maintained a constant water level in the trough using Torricellian tube principle. The water reservoir was the same as above except it was tightly sealed so no air could leak from the system. The water table was maintained 2 cm below the bench surface by rotating a hole in small cap. A variety of plants in containers, ranging from 10 cm to 5 L pots were maintained without water stress, in a greenhouse environment as well in an outdoor environment for several weeks.
