一般来说,冬天是不必考虑防日灼这个问题的。但也有例外,去年初冬一场突如其来的大雪,连续几天的阴沉过后,突然放晴。过了一两天后,我发现事情不妙——塑料棚里的几盆墨兰被晒坏了。 In general, the winter does not have to consider the issue of anti-sunburn. But there are exceptions, a sudden heavy snowfall in early winter last year, after a few days of gloomy, suddenly cleared up. After a day or two, I found out that things were not working - the pots of Cymbidium in the plastic shed were sunburnt.
