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(fèi)者會(huì)購(gòu)買(mǎi)有機(jī)食品，是因?yàn)樗麄冋J(rèn)為這些是健康味美的綠色食品。但這個(gè)觀點(diǎn)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(guó)的一組科學(xué)家通過(guò)觀察草莓來(lái)探究該觀點(diǎn)到底正確與否。為此，科學(xué)家們研究了13塊同期種植有機(jī)草莓和普通草莓的種植地。研究發(fā)現(xiàn)，有機(jī)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(jī)草莓比較小，但是純果肉卻要比普通草莓多得多，保質(zhì)期也較長(zhǎng)。

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(jī)土壤中含有較多的微生物。綜上，該項(xiàng)研究為上述觀點(diǎn)提供了有力的科學(xué)依據(jù)?！豆部茖W(xué)圖書(shū)館·綜合》上刊載了該研究。研究人員認(rèn)為，有機(jī)培養(yǎng)方式與傳統(tǒng)種植方式相結(jié)合定能開(kāi)創(chuàng)新未來(lái)~
