额尔古纳左旗位于内蒙呼盟大兴安岭林区东北部,处于东经120°12′～122°55′,北纬50°22′～52°30′之间,辖地面积19929平方公里,平均海拔1000米,年降水量450毫米左右,年平均温度—5.5℃,属寒温带湿润型森林气候,并具有大陆性季风气候的某些特征。气温年、日较差大,冬长无夏,春秋相连。该旗是我国重要木材生产基地之一,是一个天然广阔的野生果园。野果的种类多、分布广、蕴藏量大、用途广,开发利用潜力大,是振兴林区经济得天独厚的资源优势。为摸清当地主要野生果树的物候期,促进林区野果资源的开发利用,从1985年起对当地27种主要野生果树进行了每周一次定期定点的观察记载。三年来,基本上掌握了它们在当地正常年份下的物候期,并整理成表。从表中看出:野生果树的休眠期长达七、八个月,主要原因是高寒气温低所致。但这里的野生果树具有萌发早、生长发育快的特点。从萌发到成熟一般80～100天,象东方草莓、蓝靛果只需60～80天 The Erguna Zuoqi is located in the northeast of Daxinganling Forest District, Inner Mongolia, at an interval of 120 ° 12’-122 ° 55’E and latitude 50 ° 22’-52 ° 30’N, covering an area of ​​19929 square kilometers with an average elevation of 1000 meters, the annual rainfall of about 450 mm, the annual average temperature of -5.5 ℃, is a cold temperate humid forest climate, and has some characteristics of the continental monsoon climate. Temperature year, day big difference, winter long no summer, spring and autumn. The flag is one of China’s major timber production base, is a vast natural wild orchards. Wild fruits of many types, widely distributed, large reserves, wide use, great potential for development and utilization, is to revitalize the economic advantages of forest resources. In order to find out the phenophase of the main wild fruit trees in the area and promote the development and utilization of the wild fruit resources in the forest area, we have conducted weekly fixed observation and recordation of 27 major wild fruit trees from 1985 onwards. In the past three years, they have basically mastered their phenophase under normal local conditions and sorted them into tables. Seen from the table: the dormant period of wild fruit trees as long as seven or eight months, mainly due to the alpine temperature is low. However, the wild fruit trees here have the characteristics of early germination, rapid growth and development. From germination to maturity generally 80 to 100 days, like Oriental Strawberry, Lonicera edulis only 60 to 80 days
