白兰在江苏如东地区只能盆栽,冬季要移入室内,并采取增温措施。假如措施不力,往往会遭冻害。几年前一次偶然的机会,我发现剪叶是安全越冬的好办法。我家中养了一棵白兰,从11月温度逐渐下降后就移入室内,可当温度降到4℃时,叶片发生了冻害,先是焦枯、卷缩,以后掉落。见此情况,我立即将全部叶片剪光,使本来的常绿树变成了落叶树。原来,白兰易受冻害的是叶片,将其剪光后,根茎尚能耐寒,并未遭受冻害。转年3月温度渐高后,我给它换盆加土施入基肥,4月下旬它又重新萌发新芽。谷雨前我将其移出室外,先向阴后向阳。当温度达20℃左右时,新叶很快萌发。到了5月 Prynne Rudong in Jiangsu Province can only potted plants, winter to be moved into the room, and take measures to increase the temperature. If the measures are not effective, they will often be frostbite. A few years ago by chance, I found that cutting leaves is a good safe winter. My family has raised a brandy, from November after the temperature gradually dropped into the room, but when the temperature dropped to 4 ℃, the leaves of the freeze injury, the first coke, curling, falling later. Seeing this situation, I immediately cut all the leaves, so that the evergreen tree has become a deciduous tree. It turned out that Prynne susceptible to frost damage is the leaves, its cutting light, the root can still tolerate the cold, did not suffer frost damage. Turned up in March the temperature is getting higher, I give it to change pots and basins applied to the basal fertilizer, in late April it re-germination of new shoots. I will be out of the valley before the rain, the first to the posterior yang. When the temperature reaches about 20 ℃, new leaves germinate rapidly. In May
