VOA慢速英語: 法國農(nóng)民使用無人機(jī)來檢測他們的作物

French Farmers Use Drones to Examine Their Crops
法國農(nóng)民使用無人機(jī)檢測作物
It used to be mostly the military that used small, unpiloted aircraft, called "drones." The little planes were very costly. But as they have dropped in price more people have begun to use them. Rescue workers and farmers are among the new users.
過去軍事上使用一種小型的、無人駕駛的“無人機(jī)”。這種無人機(jī)很昂貴。但是隨著價格的下降，更多的人開始使用無人機(jī)，搜救人員和農(nóng)民是無人機(jī)新用戶的群體。
A company in France is using drones to help farmers examine their crops and limit the amount of fertilizer they use.
法國一家公司使用無人機(jī)幫助農(nóng)民檢測他們的作物，限制肥料使用的數(shù)量。
The fast rate of development of computer technology, image sensing devices, satellite navigation and smartphones has led to lower-priced drones. Researchers and developers have learned how to build smaller and less-costly drones sought by individuals, companies and governments.
計(jì)算機(jī)技術(shù)、圖像傳感設(shè)備、衛(wèi)星導(dǎo)航和智能手機(jī)的迅速發(fā)展，這些因素導(dǎo)致無人機(jī)價格的下降。研究者和開發(fā)者已經(jīng)掌握如何制造滿足個人、公司和政府需求的更小型、成本更低的無人機(jī)。
Moviemakers are using drones to film from the sky. Historians use them when they explore ancient buildings. Rescue workers use them to look for people. And now farmers are using them to monitor their crops.
電影制片人使用無人機(jī)實(shí)現(xiàn)空中拍攝。歷史學(xué)家使用無人機(jī)探測古建筑。搜救人員靠無人機(jī)進(jìn)行搜救?，F(xiàn)在農(nóng)民運(yùn)用無人機(jī)來監(jiān)控他們的作物。
Romain Faroux is a French businessman who starts companies. His father was a farmer. He believed drones could help farmers. He helped create a company that developed a small drone that could be controlled by people on the ground. They called it "Agridrone." It uses a special "optical sensor" to examine crops.
羅梅因·法魯克是法國一個商人，開著一家公司。他的父親是農(nóng)民，他相信無人機(jī)能夠幫助農(nóng)戶。他創(chuàng)辦了一家公司，用來研發(fā)能被地面人員控制的小型無人機(jī)。他們稱之為“農(nóng)業(yè)無人機(jī)”，它采用了一種特殊的“光學(xué)傳感器”來檢測作物。
He says the technology used is similar to that used by smartphones -- except it has wings. He says the industrialization of electronic parts for smartphones and tablets lets them get the technology -- including GPS -- at a very low price.
他表示無人機(jī)采用的技術(shù)跟智能手機(jī)的技術(shù)相似——除了無人機(jī)有雙翅膀之外。他表示智能手機(jī)和平板電腦的電子部件的產(chǎn)業(yè)化生產(chǎn)讓他們以一種低廉的價格獲得包括GPS定位系統(tǒng)的技術(shù)。
A computer program directs the drone to fly over the crops. The sensor on the drone records four different-colored "bands" of sunlight that are reflected off the crops.
電腦程序操控著無人機(jī)在作物上空飛行，無人機(jī)上的傳感器記錄陽光照射，作物反應(yīng)的四種不同顏色狀態(tài)。
Jean-Baptiste Bruggeman is a farmer. He says the drone flies over his crops at different times of the season. He says this provides a lot of information about his crops.
吉恩·巴普提斯特·布魯格曼是個農(nóng)民。他說在不同時節(jié)的不同時間，無人機(jī)飛越作物上空，向他提供了很多關(guān)于作物的信息。
He says the drone pictures show him the exact amount of fertilizer the crops need. He says it also shows exactly where the fertilizer is needed. Some areas of a field may need more than others.
無人機(jī)展示的圖像告訴他作物所需肥料的精確數(shù)量，還能讓他清楚哪一部分需要化肥，一些區(qū)域也許比其他區(qū)域更需要化肥。
As a result, Mr. Bruggeman says there is reduced nitrogen from the fertilizer after the harvest. This helps nature.
布魯格曼表示收獲后的肥料中的含氮量減少，有助于土地修養(yǎng)生息。
Romain Faroux says farmers use information gathered by the Agridrone to place fertilizer only in areas where it was needed. This saves money and reduces pollution. Before they used the drones, farmers would put the same amount of fertilizer everywhere.
羅梅因·法魯克說農(nóng)民根據(jù)無人機(jī)檢測、收集的信息來向需要的區(qū)域投放化肥。這樣既節(jié)省錢也會減少污染。使用無人機(jī)之前，農(nóng)戶會給所有的土地撒化肥。
Drones also save time because farmers can examine up to three hectares in about a minute.
無人機(jī)可以節(jié)省時間，這樣農(nóng)戶用一分鐘左右就可以檢測三公頃的作物。
