[ Method ] By the study of the phenological observation, and the relations with temperature, air humidity and soil temperature, the growth law of 0. elatus was grasped. [ Result ] Sprouting time of 0. elatus started from May 7, for a period of eight days, when the daily mean temperature was 15℃, air humidity was 41% and the soil temperature was 8.5 ℃. Leaf-expansion period started from May 15, for a period of nine days, when the daily mean temperature was 26 ℃, air humidity was 43.5% and the soil temperature was 15.7℃. Productive phase started from August 8, when the daily mean temperature was 26 ℃ , air humidity was 81% and the soil temperature was 26.7 ℃. Deciduous period started from October 15, when the daily mean temperature was 14 ℃, air humidity was 53% and the soil temperature was 13.1℃. [Conclusion] Sprouting time was May 7, leaf-expansion period was May 15, productive phase was August 8, deciduous period was October 15.
