Blowing bubbles: Soapy spheres pop pollen on fruit trees 科學(xué)家吹泡泡受啟發(fā)：肥皂泡可為果樹(shù)授粉
日本的研究人員已經(jīng)成功地利用肥皂泡薄膜中攜帶的花粉為梨樹(shù)授粉。由于全世界蜜蜂數(shù)量的減少，科學(xué)家們一直在尋找給作物授粉的替代方法。
Beloved by children and many adults, soap bubbles would hardly seem to be the most robust vehicle for pollinating fruit and vegetables. But Japanese researchers have found that these delicate spheres can each carry up to 2,000 grains of pollen, and their gentle kiss is strong enough to fertilise a flowering pear tree.
深受兒童和許多成年人的喜愛(ài)，肥皂泡似乎不是給果蔬授粉的最有力的載體。但日本的研究人員們發(fā)現(xiàn)，這些易碎的球體每個(gè)都能攜帶多達(dá)2000個(gè)花粉顆粒，它們溫柔的輕吻足以使一棵開(kāi)花的梨樹(shù)受粉。
The lead researcher had previously experimented with drones for pollination without much success. But one day, while blowing bubbles with his young son in a park, inspiration literally popped up in front of his face.
這項(xiàng)研究的首席研究員曾實(shí)驗(yàn)過(guò)用無(wú)人機(jī)授粉，但成效不大。但是有一天，當(dāng)他和年幼的兒子在公園里吹泡泡的時(shí)候，靈感頓時(shí)出現(xiàn)在他的面前。
After a few chemical alterations to the soapy mixture, the scientists loaded up their bubble guns and headed to a local pear orchard. Sixteen days later, young fruits started to form at a similar rate to trees pollinated by hand.
在對(duì)肥皂混合物做出了一些化學(xué)改變之后，科學(xué)家們把肥皂混合物裝進(jìn)汽泡槍，前往當(dāng)?shù)氐囊粋€(gè)梨園。16天后，幼果開(kāi)始形成，其速度與人工授粉的樹(shù)木不相上下。
While scientists agree that natural pollination is the best method of fertilising fruit and veg, the Japanese team believe that drones armed with soap bubble sprayers could, in future, take some of the strain from hardworking bees.
雖然科學(xué)家們一致認(rèn)為自然傳粉是給果蔬授粉的最佳方法，但這個(gè)日本的研究小組認(rèn)為，配有肥皂泡噴灑器的無(wú)人機(jī)將來(lái)可能會(huì)減輕勤勞工作的蜜蜂的壓力。
