Companion planting is the idea that some kinds of plants can help each other grow. Plants thatare compatible together generally have similar needs in terms of nutrients, soil and moisturelevels.
混栽的想法在于某些種類的植物有助于彼此生長?；ハ嗉嫒莸闹参镆话阍陴B(yǎng)分、土壤和水分含量上有類似需求。
Advice about which plants are compatible is sometimes based more on tradition than proof.But experts say there is evidence to support certain combinations. These can improveharvests, reduce disease and help with pest control by attracting helpful insects.
有關(guān)哪些植物能夠互相兼容有時候更多取決于傳統(tǒng)而不是論證。但專家表示某些組合有證據(jù)作為支持。這些組合可以提高收成、減少疾病，并且通過吸引益蟲來幫助控制蟲害。
For example, some kinds of soil bacteria take nitrogen from the air and make it into a formthat plants can use. The plants hold the nitrogen in their roots. Legumes are especially good atthis nitrogen-fixing. Then any crops that share the same space as the legumes can get thenitrogen as the roots decompose.
例如，某些類型的土壤細(xì)菌從空氣中吸收氮并將其轉(zhuǎn)化成為一種植物能夠利用的形式。這類植物將氮保存到根部，豆類尤其擅長于這樣固氮。這樣共享土壤的任何作物，例如豆類，可以在根部分解時獲得這些氮。
Beans and potatoes can also share territory well because their roots reach different levels inthe soil. Deep-rooted vegetables get nutrients and moisture from lower down in the soil, so theydo not compete with plants with shallower roots.
菜豆和馬鈴薯也能很好地分享領(lǐng)土，因?yàn)樗鼈兊母谕寥乐械纳疃炔煌?。深根類蔬菜從更深的土壤中獲得養(yǎng)分和水分，因此它們不會與淺根植物競爭。
But some plants placed together may harm each other's development. For example, tomatoesdo not like wet soil but watercress does, so you would probably want to keep them separated.
但有些植物放到一塊可能會損害各自的發(fā)展。例如，西紅柿不喜歡潮濕的土壤，但豆瓣菜卻喜歡潮濕的土壤，所以你可能需要將它們分開。
Some kinds of produce should be kept apart even after being harvested. This is because ofethylene gas. Ethylene is a plant hormone that can cause some foods to ripen too quickly.Apples release ethylene gas. Apricots, melons and tomatoes also release a lot of ethylene.Some vegetable are easily affected by ethylene, including asparagus, broccoli, cabbage andcucumbers.
某些種類的農(nóng)產(chǎn)品即使在收獲后也應(yīng)當(dāng)隔離開。這是因?yàn)橐蚁?。乙烯是一種植物激素，能夠?qū)е乱恍┦澄锍墒焯臁ＬO果會釋放乙烯。杏、甜瓜和西紅柿也釋放乙烯。有些蔬菜很容易受乙烯影響，其中包括蘆筍，西蘭花，白菜和黃瓜。
This risk of ripening too soon is why markets often separate high ethylene-producing foodsfrom those that are sensitive to the gas.
這種過快催熟的風(fēng)險就是市場上經(jīng)常將產(chǎn)生乙烯多的食物和對乙烯敏感的食物分開的原因。
But if you put an apple in a bag with a green banana, the ethylene from the apple will make thebanana ready to eat sooner.
但如果你將一個蘋果和未熟的香蕉放進(jìn)一個袋子里，蘋果釋放的乙烯將使香蕉很快可以食用。
What about peaches, plums and nectarines that are too firm to eat? These kinds of fruit do notneed any help from an apple — they release enough ethylene to ripen themselves. But thatdoes not mean there is no way to get the job done faster.
桃子、李子、油桃吃起來太硬怎么辦?這類水果不需要蘋果幫忙，它們能夠釋放足夠多的乙烯使自身成熟。但這并不意味著沒辦法使這個成熟的過程更快一些。
Growers suggest placing the fruit in a fruit bowl or in a paper bag with the top folded over.Keep the fruit at room temperature, out of direct sunlight. Once the fruit is soft enough toyour liking, either use it or put it in the refrigerator to keep it from getting too ripe. Yuck.
種植者建議將這些水果放入水果盤或紙袋里并蓋好。將這些水果保持在室溫下避免陽光直射。一旦水果軟到你喜歡的程度，要么吃了它，要么把它放入冰箱以防止它變得太熟。

You can almost hear the law of unintended consequences at work among the flora and fauna ofnorthwestern New Mexico.
你幾乎不敢相信新墨西哥州西北動植物研究工作帶來意想不到的結(jié)果。
Thousands of natural gas wells dot the landscape there, along with the compressors that getthe gaseous fuel ready to travel through pipelines. The compressor rumble is constant, andseems to be attracting black-chinned hummingbirds, according to a new experiment. Thefindings appeared this week in the journalProceedings of the Royal Society B.

Researchers set up test flower beds and tracked bird landings. They found that thehummingbirds were five times more likely to visit noisy areas. Why? Perhaps because thewestern scrub jay tends to avoid noise. And western scrub jays eat baby hummingbirds. Thesituation is good for wildflowers that are pollinated by the hummingbirds.
研究人員通過建立花圃并跟蹤測試鳥類降落次數(shù)。他們發(fā)現(xiàn)蜂鳥有超過五倍可能性去喧鬧的地區(qū)這是為什么?或許是因?yàn)槲鞣桨珮渌渗f不喜歡噪音，而西方矮樹松鴉喜歡吃蜂鳥幼鳥。這樣由蜂鳥授粉的野花在鬧市區(qū)開的很好。
But the absence of jays seems to be bad for other plants. For example, the pinon pine relies onscrub jaysto spread its seeds. As a result, pine seedlings were four times less abundant atnoisy sites than quiet ones.

At first glance, this old bush looks much like many other plants in the area, but researchers saythis shrub known as Palmer's Oak is considerably more special, because they believe it to be13,000 years old, one of the oldest plants in the country. And it's literally right across the streetfrom Jurupa Hills residence Samuel Cano.
第一眼看上去，這些灌木和這片地區(qū)的其他植物無甚區(qū)別，但研究人員說這種叫做Palmer's Oak的灌木其實(shí)十分特別，因?yàn)樗鼈兪沁@個國家最古老的植物，已經(jīng)活了一萬三千年。生長面積從Jurupa Hills蔓延至SamuelCanon。
13,000 years old,I mean that's a long time. A lot of history.Wow! And this literally couldpredate man in North America if my guesses are right. Scientist Andrew Sanders says what hefound odd about this particular plant is that it's typically found high in the mountains, notdown here.So it got him and others thinking what if this oak bush sprouted during a muchcolder era. So they dated the plant and sure enough it probably was around during the ice age.
一萬三千年，真是很長的一段時間。有很長的歷史。哇!如果我的猜測正確，這種植物比北美洲早期人類出現(xiàn)得還要早。科學(xué)家Andrew Sanders說，這種植物的奇怪之處在于，海拔越高，它就長得越高，海拔低就不會長得高。因此，Andrew和其他人都認(rèn)為這種橡木灌木曾生活在較冷的區(qū)域。研究人員通過數(shù)據(jù)進(jìn)行研究推測這些植物產(chǎn)生于冰河時代。
The main thing that strikes me is that we've got where literally looking at a bit of what theworld was like in the Ice Age. I mean we don't have to look at a fossil in this case. We can seethe living individuals. So as far as researchers can tell this exact plant was growing here at thesame time mastodons and sabre tooth tigers were roaming the area. The big question: how didit survive all these years.
最震撼我的是，我們能夠在理論上知道冰河時代地球上的情形。我是說，我們不用化石印證，而是能看到現(xiàn)存的植物個體。研究人員驚訝于這種植物是如何在乳齒象和劍齒虎四處游蕩的環(huán)境下生存的。
I think the main thing is that it's manage to get into this narrow rocky crevasse on a northfacing slope. So it's start to shade it. Scientists believe the shrub to be at least 1,000 yearsolder than this creosote bushes in Palm Springs. So while that they may not look like much, this75-foot-long old bush is in fact the oldest known living plant in the state,right here in JurupaHills.
