Grow plants without soil美國農(nóng)民玩起了“魚糞種菜”

朱欣

蔬菜不生長在土中，而在水中栽培，你想象過嗎？ 一個漂亮的玻璃魚缸，一棵綠油油的水培植物，再來幾條活潑的小魚，生態(tài)水培技術(shù)你也可以擁有。

早在幾年前，美國的一位女士竟然就開始在家中建造這樣的生態(tài)水培系統(tǒng)了，讓我們一起來看看她都做了什么吧！

文本解說

美國的一位女士開始在家中建造生態(tài)水培系統(tǒng)，這個系統(tǒng)不僅不會對環(huán)境造成污染，還可以節(jié)約資源。

Aquaponics（魚菜共生技術(shù)） is the idea of producing vegetables and fish in the same closed system. It combines aquaculture（水產(chǎn)養(yǎng)殖）， or fish farming， with hydroponics（水培）， a way to grow plants without soil. Supporters see aquaponics as a way to increase world food supplies and reduce climate change， groundwater pollution and overfishing.

Ms Bernstein grew plants in water with a chemical fertilizer for years. Then she discovered she could use waste water from fish to grow organic vegetables and fruit.

“Honestly， I was very skeptical and just couldn't believe that something as simple as fish waste could become a complete fertilizer. So I had to actually see a system that was in a friend's basement. But when I did， it changed my life.” That was three years ago. Ms Bernstein built her first system with her son outside her home in Boulder， Colorado. Her plants grow in containers. There are no weeds in her aquaponics garden， and no need to worry about watering. “I， just this? morning， pulled? four? radishes

（蘿卜） and some lettuce（生菜） for lunch. In my greenhouse right now， I grow all sorts of herbs， tomatoes， peppers.” Ms Bernstein started her own business called the Aquaponics Source. She has a YouTube channel， teaches aquaponics at the Denver Botanic Gardens and recently published a book.

Aquaponics farmer James Godsil says the Internet is helping many aquaponic gardeners connect and learn from one another. Three years ago， Mr Godsil helped create an aquaponics farm in Milwaukee， Wisconsin， called Sweet Water Organics. In twenty？鄄ten， he helped establish a foundation.

“The Sweet Water Foundation was dedicated to democratizing（使民主化） and globalizing the information and the methodologies required to advance this very Earth-friendly food production system， which， by the way， only uses about ten percent of the water normal farming does， and uses no pesticides. It's all natural.”

Mr Godsil is traveling to other countries to teach aquaponics.“I was asked to go to Venezuela this March. And I'm working with people who have a project in Ecuador. I'm

working with people in the Congo and Uganda and Tanzania.”

Subra Mukherjee is with a group in Kolkata， India， called the Society for Appropriate Rural Technology for Sustainability. The group is working with the foundation to develop aquaponics in a community in West Bengal with poor soil conditions for growing food.
