Organic Strawberries Beat Conventionally Grown in Test Plots
Some consumers buy organically grown foods because they believe the products are healthier, tastier and better for the environment. But is this assessment true?
消費者會購買有機食品,是因為他們認為這些是健康味美的綠色食品。但這個觀點真的正確嗎?
To find out, a group of U.S.-based scientists looked at strawberries. For the study, the researchers analyzed 13 plots of organic strawberries and conventional strawberries grown side by side. They found that the organic strawberries contained 10 percent more Vitamin C and antioxidants than their conventional counterparts. The organic strawberries were smaller on average than conventional berries, but each piece of organic fruit actually contained more dry matter—the meat, if you will, of the berry. The organic berries also had a longer shelf-life.
美國的一組科學家通過觀察草莓來探究該觀點到底正確與否。為此,科學家們研究了13塊同期種植有機草莓和普通草莓的種植地。研究發(fā)現,有機草莓含有的維生素C和抗氧化成分要比普通草莓多10%。雖然有機草莓比較小,但是純果肉卻要比普通草莓多得多,保質期也較長。
And finally, a soil analysis showed that the organic plots contained more microorganisms than conventional acreage. So, the study adds some scientific evidence to the belief that organic berries are healthier, tastier and more environmentally sound. The findings are published in the journal Public Library of Science ONE. [John Reganold, L] Researchers believe that combining organic methods with some conventional agricultural practices will provide the produce of the future.
此外,土壤分析顯示,有機土壤中含有較多的微生物。綜上,該項研究為上述觀點提供了有力的科學依據?!豆部茖W圖書館·綜合》上刊載了該研究。研究人員認為,有機培養(yǎng)方式與傳統(tǒng)種植方式相結合定能開創(chuàng)新未來~
