The radial growth of eight individuals of and environmental factors were monitored by Dendrometer and automatic meteorological station in the western Qilian Mountains. The Gompertz function fitted results showed that the radial growth of started on April 19, April 17, and April 10 in 2018, 2019 and 2020, respectively, and that the radial growth started when daily mean temperature exceeded 5.5 ℃. The radial growth of ended on August 17, August 21, and July 19 in the three years, respectively. The ending time of radial growth was related to precipitation at the end of growing season. The radial growth of was strongly inhibited by drought, and it had the strongest correlation with daily mean temperature (negative correlation) and daily precipitation (positive correlation) in July. The correlation of radial growth with the daily precipitation in the early growing season (May) showed significant inter-annual variation.
在祁连山西部,利用测树仪和自动气象站对8株[物种名称缺失]的径向生长及环境因子进行了监测。Gompertz函数拟合结果表明,[物种名称缺失]的径向生长分别于2018年4月19日、2019年4月17日和2020年4月10日开始,且当日平均温度超过5.5℃时径向生长开始。三年中,[物种名称缺失]的径向生长分别于8月17日、8月21日和7月19日结束。径向生长的结束时间与生长季末期的降水量有关。[物种名称缺失]的径向生长受到干旱的强烈抑制,且在7月与日平均温度(负相关)和日降水量(正相关)的相关性最强。生长季早期(5月)径向生长与日降水量的相关性表现出显著的年际变化。
