芹菜苗期管理。

答案

参考答案:

苗期管理:播后如遇干旱,可每天傍晚浇1次小水,保持地面湿润,直到出苗。出齐苗后,在傍晚太阳光弱时,要拿掉畦面上的覆盖物。随着小苗的生长,要逐步撤掉遮荫覆盖物。出苗后至幼苗长出2~3片真叶前,因根系数量还很少,故每隔2~3d应浇1次水,使畦面经常保持见干见湿状态。浇水时间以早晚为宜。当芹菜长到5~6片叶时,根系比较发达,应适当控制水分,防止徒长,并注意防止蚜虫危害。在芹菜苗期一般不追肥。如发现缺肥长势弱时,在3~4片真叶时可随水追施硫酸铵,每667m2施用10kg。在幼苗l~2片真叶时,进行1~2次间苗或分苗,苗距8cm见方,以扩大营养面积,保证秧苗健壮生长,并结合间苗或分苗进行除草。一般本芹苗龄50d左右,西芹的苗龄为60~70d,幼苗长至10~12cm时,即可定植。

In Germany, English expressions are used in conversations and increasingly in written form. Advertisements are often expressed completely in English. When I go to the gym, there are “aerobic-classes (增氧健身法课程)”. We “warm up”. We go “jogging.” In business, we attend a “meeting” and we have “good connections.”

Other nations, like France, have taken action to protect their language from the influence of “Americanization”. In Germany, however, there is concern that those rules could be connected with Hitler’s Third Reich (帝国), when the language had to be pure. If the government curbed(限制)the use of English words now, this could be considered by some as a return to that terrible past.

Some German citizens are now trying to stop the use of English vocabulary in German. However, I think generally it is not a big deal to use some common English expressions as they often describe things more directly. But we should know that it is important to use English correctly. All too often, bad English is spoken or even written instead of good German. The proper use of the German language would be the better choice. However, there are some fields that require the use of English words, for example, in the high-tech communication and the Internet fields, there is no alternative to English. Also, I think sometimes I have to speak English when I introduce some scenic places to tourists.

I think you have to find a balance and decide when it is better to use good German in place of bad English or when the use of correct English words is more suitable. Languages have always changed naturally, and I disagree with a restriction by law. Some nice expressions borrowed from other languages can make a conversation more vivid.
