月季是很好的花坛花境材料,但到目前为止,所有的现代月季品种地上部都只能耐—20℃左右的低温。而我国北方有些高寒地区冬季的绝对低温可达—36℃以下,露地栽培普通月季,必须埋土防寒越冬,否则地上部分会全部冻死或整株死亡。这就使月季在高寒地区的园林绿化应用受到限制。 Rose is a good material for flower beds and flowers, but up to now all the modern rose varieties can only tolerate temperatures around -20 ° C. In northern China, some alpine regions can reach an absolute low temperature of -36 ° C in winter, and open-field cultivation of ordinary roses must be buried in winter to protect themselves from cold or the whole part of the ground will be frozen to death or the entire plant dies. This makes the use of the landscaping of the rose in alpine regions limited.
