双语阅读︱把植物放在室外之前先使其“变得耐寒”
The month of May is the best planting time in many areas in the northern half of the world.
在地球北半部的许多地区，五月是最佳播种时间。
Many gardeners are visiting garden centers now to buy plants.
现在有许多园艺爱好者去园艺中心买植物。
Those who have grown plants from seeds indoors may be getting ready to plant them in the garden at about this time.
那些在室内用种子培育植物的人可能会在这个时候准备把它们转种在花园里。
However, seedlings cannot usually go straight from an indoor growing area to outdoor beds and borders without risk.
然而，幼苗通常不能毫无风险地直接从室内生长区域转移到室外的苗圃和狭长花坛中。
They need to be "hardened off" first.
它们首先需要“变得耐寒”。
That means slowly introducing the plants to environmental conditions like sunlight, wind, and changes in temperature that they have not yet experienced.
这意味着要慢慢地将植物引入它们尚未经历过的环境条件，如阳光、风和温度变化。
If plants are not hardened off enough,
如果植物不够耐寒，
they could get burned by the sun or go into shock from more wind exposure or lower temperatures than they are used to.
它们可能会被太阳灼伤，因暴露在更多的风中或比过去更低的温度而严重受创。
Stressed plants can recover.
逆境植物可以恢复。
But the process usually sets their growth back by a few weeks.
但这一过程通常会让它们的生长倒退几周。
Start hardening your plants by placing them outdoors in a sheltered area that is partly protected from the sun.
可以通过将植物放置在户外遮挡部分阳光的遮蔽区让它们开始变得耐寒。
Do this for increasing periods each day for about a week before planting them in the garden.
植物放置于户外的时间每天增加一点，持续约一周，然后再将它们种植在花园里。
Protection from the sun is important.
防晒很重要。
Even the window that gets the most sun in your home or an electric growing light cannot compete with the strength of direct sunlight.
即使是你家里光照最充足的窗户，或者植物生长灯，也无法与阳光直射的强度相比。
Choose a day after the danger of frost has passed and when the temperature is above seven degrees Celsius.
选择霜冻危险过去、气温在7摄氏度以上的一天。
Place plants outside for an hour, set a timer, and then bring them back inside to a warm spot, under electric plant lights is the best choice.
将植物放在室外一小时，设个定时器，然后把它们带回室内温暖的地方，植物灯下是最好的选择。
Repeat this on the second day for two hours.
第二天重复这个过程，放在室外两个小时。
Add an hour of outdoor time each day for a week.
在一周的时间里，每天增加一小时的户外时间。
After that, they can safely be planted in their permanent homes, whether in the ground, a raised bed, or a container.
在那之后，它们可以安全地被种植在自己的永久家园中，无论是在地面上、种植床上，还是在景观盆里。
Follow the weather and keep an eye on conditions throughout the process.
在整个过程中，要关注天气，密切关注情况。
Bring plants inside if rain or severe wind threatens during their outdoor time.
户外时间如果下雨或刮风，请将植物带到室内。
Do not be concerned if there is no protection from the sun in your garden.
如果你的花园里没有防晒设施，不要担心。
You can harden your plants under an outdoor table, for example.
例如，你可以将植物放置于户外的桌子下锻炼它的耐寒性。
Under large outdoor plants works equally as well.
放置于大型户外植物下也同样有效。
If you have none of those, you can protect your plants from the sun with something like an umbrella.
如果这些条件都达不到，你可以用雨伞之类的东西来保护你的植物免受阳光带来的伤害。
If the weather is not hot, you can even plant your seedlings directly in the ground.
如果天气不热，你甚至可以直接把幼苗种在地里。
Then harden them by covering each individually with a large plastic container with its bottom and top removed.
然后用一个去掉底部和顶部的大塑料容器分别罩住它们，使它们变得耐寒。
Burying the bottom in a few centimeters of soil will hold the container in place.
把容器底部埋在几厘米深的土壤里，这样容器就能被固定住。
You can water plants through the pouring hole at the top.
你可以通过顶部的浇水孔给植物浇水。
Remove the container for each day's hardening-off period.
每天培养植物耐寒的时候将容器取出。
And then set it back into place and secure it into the soil afterward.
之后把它放回原处，固定在土壤里。
Watch your plants carefully because high temperatures and strong, direct sunlight might "cook" them.
仔细观察你的植物，因为高温和强烈的直射阳光可能会让它们“熟了”。
Follow weather conditions and use your best judgement before planting seedlings directly in the garden.
将幼苗直接种植在花园里之前，要根据天气情况做出最好的判断。
If you started plants in a greenhouse, they have already been growing in direct sunlight, so the process is easier.
如果你一开始就把植物种植在温室里，那它们已经在阳光直射下生长了，所以这个过程会更容易。
Open the windows for a few hours each day for about a week.
每天打开窗户几个小时，持续一周左右。
Then, move seedlings to a sheltered outdoor area for two hours the first day and four hours the second day.
