水池之上
There are actually many kinds of farming. It can be done on big farms in the country, in someone’s backyard, or even in a balcony garden. Farming can be done on water, which is called aquaponics.
Aquaponics is very interesting because farmers make a pond for fish like tilapia to live in. On top of the water are special shelves where plants grow, so the plants are not in dirt. Instead, they sit in a plant bed made of little rocks. Their roots grow down into the water that has been pumped out of the pond. This water feeds the plants because it is full of fish poop and extra fish food. Then, the water is pumped back into the pond. This method works so well that plants are ready to eat much sooner than those grown in regular dirt gardens.
農耕事實上有很多種。農耕可以在鄉下的大農場完成、在某人的後院, 甚至是陽台的花園都能夠實行的。農耕可在水裡進行,稱為水耕養殖。
水耕養殖是一件非常有趣的事,因為農夫造一口池塘給吳郭魚這類的魚居住。在水的上方有些特別的擱板讓植物在上面生長,因此植物不是長在土裡,而是棲息在小石頭堆成的植床裡。它們的根往下長,向下深入到池塘抽出的水裡。池裡的水提供植物所需的養分,因為裡面充滿魚糞便和額外的魚食。然後,這些水又灌回到原本的池塘裡。這個方法非常的有效,讓植物比在一般土園生長的植物還要快可以食用。
