摘要
为了掌握昆明山海棠物候特性,在雷公山选择低海拔(1 250 m)、高海拔(1 590 m)2个观测点进行为期1年的物候观测.结果是,低海拔昆明山海棠芽萌发期为4月10日至4月20日,梢枝生长期4月27日到6月6日,花生长期5月18日至7月6日,果生长期6月29日至9月25日,叶生长期4月20日至12月4日.高海拔观测点物候现象较低海拔延迟约30天.
In order to master the characteristics of hypoglaucum phenological,phenological observations were done for a year in the Leigongshan,in which two observation points were selected,low altitude is 1250m and high-altitude is 1590m.In case of low altitude the result was that bud germination period was from April 10 to April 20,shoot and shoot growth period from 27 April to 6 June,peanut long-term 18 May to 6 July,fruit growing from 29 June to 25 September,leaf growth period 20th April to 4 December.Phenological phenomena of high altitude point was delayed about 30 days than lower elevation point.
