自然的节奏,春、夏、秋、冬周而复始。表现在高等植物上,则是春生、夏荣、秋实、冬眠。我国北方,现在正是千里冰封,万里雪飘的隆冬季节。越冬植物都已转入休眠。在休眠期间,植物暂时停止生长。许多木本植物落叶,草本植物的地上部分枯死,还在生活着的部分,其生理代谢活动也都降到最低水平,而抗寒能力却显著增强。聪明的人类巧妙地利用植物休眠期的生理特点,使它们按照人的意愿生长。很久以前,我国就有利用植物休眠时机,移栽、修剪和采伐林木的好经验,这些传统技术中蕴藏着许多植物生理学知识。
The rhythm of nature, spring, summer, autumn and winter cycle again and again. Performance in higher plants, then spring, summer Rong, autumn real, hibernation. In the north of our country, it is now the winter season where thousands of miles of ice and snow float. Overwintering plants have been put to sleep. During dormancy, plants temporarily stop growing. Many woody plants deciduous, herbaceous parts of the ground dead, still living part of their physiological and metabolic activity are also reduced to the lowest level, while the ability to significantly enhance the cold. Clever human beings clever use of the physical characteristics of plant dormancy, so that they grow in accordance with the wishes of the people. Long ago, my country had good experiences in using plant dormancy times, transplanting, pruning and cutting trees. There are many plant physiology knowledge in these traditional technologies.
