翻译研讨:2010/01/12 AGRICULTURE REPORT - Keeping Plants and Trees Warm When Temperatures Drop

楼主:翼龙的嘴 日期: 回贴:2 浏览:

This is VOA Special English agriculture report.
这里是VOA特殊英语“农业报告”。

Florida in the Southeastern United States is called the sunshine state. It grows more oranges than anyplaces expert Brazil. But Arctic air has damaged some Florida oranges and strawberries in recent days. And killed fish at tropical fish farms.
在美国东南部的佛罗里达州被称作“阳光之州”。那里种植橘子的数量仅次于巴西。但是最近几天北极的冷空气损害了许多佛罗里达州的橘子和草莓,还杀死了热带鱼农场的鱼。

The unusually long period of the cold weahter has shown how even warm climates can sometimes freeze over. But protecting plants and trees in the garden may not be too diffcult, if you follow a few suggestions.

异常的长时期寒冷的天气显示了即使温暖的气候有时也能全面结冰。但是如果你遵循以下的一些建议,或许要保护果园里的庄稼和树不是太难。
Sudden cold can be the biggest threat, especially after a warm period. Plants have not had a chance to harden their defenses. Those that are actively growing or flowering are at high risk.

特别是在一个温暖期之后,突然的寒冷时最大的威胁。庄稼没有机会加强防护措施。那些正在生长和开花的作物存在高风险。

Try to choose plants that live best the cold weather, and planting areas that face west and south. Being near other growth may also provide warmth.
尝试选择最好生长在寒冷天气的作物,并且种植区域面向西方和南方。附近有其他作物也可以提供温暖。

Most frost damage takes place at night. Ice crystal from on the leaf surface. They pull moisture from the leaves and keep plant tissues form getting water.

大多数霜冻灾害发生在夜里。冰晶来自叶子表面。他们从叶子和来自取水的保存植物组织析出水分。

Cold weather is most likely to damage or kill plants, that do not have enough moisture. So keep the garden watered. Moisture soil absorbs more heat than loose, dry soil covered with more mulch or vegetation.

寒冷的天气最有可能损害或杀死作物的是使其没有足够的水分。因此保持果园的水分。潮湿的土壤比松散的土壤更能汲取热量,干燥的土壤用更多的护根或植物覆盖。

University of Arizona extension experts say covering plants and small trees with cloth or paper can help prevent frost damage. A one-hundred watt light bulb designed for outdoor use can also provide warmth. Some people place Christmas lights on young trees for warmth. The bulbs should hang
below the leaves to let the heat rise into the tree.

亚利桑那扩展大学的专家说用外套和纸覆盖作物和小树能帮助防止冰冻灾害。为户外使用设计的100瓦的灯泡也能提供温暖。为了温暖一些人在小树上防止了圣诞灯。灯泡应该挂在树叶下面,让热量散发到树里。

Cold is specially dangerous to citrus trees. Agricultural specialists at the University of California suggest putting paper or cloth around the trunk and central branches of young citrus trees.

寒冷对柑橘树特别危险。加利福尼亚大学的农业专家建议用纸和外套包裹小柑橘树的树枝和树干。

In Florida, as temperatures fell to record lows, citrus growers sprayed water on their trees to help prevent freeze damage.

在佛罗里达州,当温度跌破最低纪录时,柑橘种植者在他们的树上喷水来防止冰冻灾害。

Jim Bottcher is a master gardener with the University of Florida extension. He explains that as the water freezes, it produces heat, and the ice forms a protective blanket around the tree. If you spray a tree, keep the water away from nearby power lines. Heavy ice can form and break them.

吉姆是佛罗里达扩展大学的主园丁。他解释因为水结冰产生热,而且冰围绕着数形成一个保护罩。如果你往树上喷水,保持水与动力线的距离。沉重的冰能使它们变形和损毁。

You can also wrap a tree in palm tree frond leaves, cornstalks or fiberglass. Adding plastic film works well in rain and snow. But experts say plastic alone does not help much. 

你也能用棕榈树叶、秸秆或玻璃纤维包裹树。在雨天或雪天最好增加塑料薄膜。但是专家说只有塑料薄膜没有多少用处。

And that's the VOA Special English Agriculture Report, written by Jerilyn Watson. More gardening and agricultural advice is at www.unsv.com. I'm Bob Doughty.

1、They pull moisture from the leaves and keep plant tissues from getting water.

他们从叶子上抽取湿气并阻止植物组织获得水份。

2、Cold weather is most likely to damage or kill plants that do not have enough moisture. So keep the garden watered. Moist soil absorbs more heat than loose,dry soil covered with more mulch or vegetation.

寒冷的天气最有可能损害或杀死没有足够的水分作物。因此要坚持给果园浇水。潮湿的土壤比有覆盖物或者植被的松散、干燥的土壤吸收更多的热量。
