笔者在重庆地区阳台盆栽米兰已经12年了。通过对阳台温湿度的观察,我发现其生长期为每年4月初至12月中旬,旺长期为每年5月至11月上旬,12月下旬至翌年清明前为休眠期。其适生温度为25℃～35℃,冬季能耐5℃以上低温。若日常管理得法,露天还能忍耐2～3天3℃左右的严寒,而且不显冻害,清明以后仍能正常生长和开花。我认为主要管理办法有三:其一,培育壮苗壮苗是顺利越冬的先决条件。盆栽米兰,只要管理得法,每年在重庆地区能开花5次,每次花期约半月左右,故植株养分消耗极大。因此每次花后必须及时追施一次以磷钾肥为主的复合肥,每隔10天再向枝叶喷施一次3‰的磷酸二氢
I have been in Chongqing balcony potted Milan for 12 years. Through the observation of the temperature and humidity of the balcony, I found that the growth period is from early April to mid-December each year. The long-term period is from May to the first ten days of each year. From late December to the next year, Ching Ming is dormant. Its suitable temperature is 25 ℃ ~ 35 ℃, the winter can withstand low temperature above 5 ℃. If the day-to-day management of the law, the open air can bear 2 to 3 days about 3 ℃ cold, but not significant frost damage, the normal growth and flowering after the Ching Ming. I think there are three main management methods: First, to cultivate strong seedlings is a prerequisite for smooth winter. Planting Milan, as long as the law is managed, each year in Chongqing can bloom 5 times, each about about half a flowering period, so the plant nutrient consumption is great. Therefore, after each flower must be timely topdressing to phosphorus and potassium-based compound fertilizer, once again every 10 days to the foliage spraying 3 ‰ of dihydrogen phosphate
