     This is the VOA Special English Agriculture Report.
     这里是美国之声慢速英语的农业报道
    
     Grafting is a way to produce plants from pieces of existing plants instead of seeds.
     嫁接是将现有的植物代替种子而生产出植物的一种方式.
   
     Branches or buds are cut from one plant and placed on a related kind of plant. The branch or bud that is grafted is called the scion. The plant that accepts the graft is called the rootstock.
     切下某种植物的枝或芽,将它放置在同一种类的植物上.被嫁接上去的枝或芽叫做接穗,接受嫁接的植物叫做钻木.
  
    Grafting can join scions with desirable qualities to rootstock that is strong and resists disease and insects.
     嫁接能将品质较好的接穗连接到强壮且能抵抗病害和昆虫的钻木上去.
  
     A graft can be cut several ways. One way is a cleft graft. It requires a scion with several buds on it. The bottom of the scion is cut in the shape of the letter V.
     嫁接有几种剪切方法.其一是切口嫁接.这要求接穗里有数个芽的在其中.接穗的底部要被切成字幕V的形状.
    
     The scion is then securely placed into a cut on the rootstock. Material called a growth medium is put on the joint to keep it from getting dry and to help the two plants grow together.
     然后就是把接穗稳固的放置在钻木的切口处.将叫做发育媒介的架子放在连接处,以防植物脱水,也能更好的帮助这2种植物能生长在一起.
   
     Many fruits and nuts have been improved through grafting. Flowers can also be improved this way.
     许多植物和坚果一直都通过嫁接而被改进.花卉同样也通过这种方式被改进.
    
     Some common fruit trees such as sweet cherries and McIntosh apples have to be grafted. Grafting is also used to produce seedless fruits like navel oranges and seedless watermelons.
     例如许多像甜樱桃和麦金托什苹果这样常见的水果树必须被嫁接.嫁接也被用在像生产脐橙和西瓜这样的无壳水果中.
   
      Grafting continues to hold an important place in agriculture even in an age of modern genetic engineering.
     即使是在现今的转基因农业时代,嫁接仍处于一个很重要的位置.
    
     Recently we told you about a study of genetically engineered crops and how they have affected farming in the United States. The study found that many farmers have better harvests, better weed control and fewer losses from insect damage compared to traditional crops.
     近来我们跟你们讲述了一些关于转基因作物的研究以及他们对美国的农业的影响.研究发现相比传统作物,许多农户种植的转基因作物的收成会更好,它能更好的控制杂草,遭受昆虫灾害的损失也更小.
   
    
     Our story brought a number of comments, including this one from Odalberto Domingos Casonatto in Brazil. He wrote that in his town the population depends on agriculture and transgenic crops. He says it is true that such crops can have higher output with less cost, but added:
     我们的报道引来了许多的评论,包括一名来自巴西Odalberto Domingos Casonatto的听众.他写到在他们镇上的人口都依赖于农业和转基因作物.他表示转基因作物的成本低却高产量是真实的.他还附加到:
    
     No one knows the consequences that will have on soil fertility and the human body. Only the future will tell us the truth about transgenic food.
     没有人知道转基因作物对土壤的肥沃和人体会带来什么后果.只有未来能告诉我们关于转基因食物的真相.
    
     Christian in France expressed a different concern, saying: The big problem of the transgenic seeds is that they are the monopoly of big companies. The small farmers cannot reproduce any more seeds by themselves.
     法国的Christian表达了不同的忧虑,他说:“转基因种子最大的问题是他们都被大型公司所垄断.而小型的农户不能自我繁殖出任何种子.”
    
      And Joom from Thailand wrote: I don't care where the crops come from, natural plants or genetic engineering, as long as we can produce food enough for people.
     来自台湾的Joom写到:“我不在乎作物来自那儿,天然作物还是转基因工程作物,只要我们能为人类生产供给出足够的食物就行.
