智能農場扎根于韓國地下

山西太原 史 婕

韓國一家公司在一條廢棄的公路隧道內經營著該國最大的室內“智能農場”。在這里，不是太陽而是LED燈照耀在多層垂直架上。

The South Korean company NextOn is operating an indoor “smart farm”inside a former road tunnel（隧道）.

The farm produces fruits and vegetables hydroponically（用水培法），which means the plants do not grow in the ground.Instead，they grow on vertical equipment that provides a continuous flow of water.Indoor farms use artificial light instead of sunlight.

But what makes the farm even more unusual is the fact that it sits inside a huge tunnel originally built for a highway butclosed downa couple of years later.NextOn took over the tunnel and turned it into a high-tech farm.

NextOn officials say the tunnel environmentpermitsideal conditions for an indoor farm.It keeps a steady temperature of between 10 and 22 degrees Celsius.The tunnel is also completely dark，making it easier to provide exactly the right amount of artificial light.The farming system can produce more than 60 different kinds of fruits and vegetables which are healthier since harmful chemicals are not necessary to prevent large insect invasions （入侵）.

In South Korea，indoor vertical farming is seen as a possible solution to crop damagerelated toextreme weather that could get worse due to climate change.According to farming experts， high-tech farms， also used in Dubai and Israel，could be a good way to deal with problems many countries including South Korea are facing with： weather， decreasing farmland and fewer agricultural workers.

It can be difficult， though， for smart farmers to make a profit because of the high cost of building and operating.But NextOn cut its building costs in half by using the former tunnel and developing its own lighting and water systems.These technologies reduced water and energy use and the need for workers.Sensors（傳感器）also measure things such as temperature，humidity（濕度）， light and air quality.This way the crops will cost less than other organic（有機的）vegetables grown today.
