摘要
通过定期定株观测和样地调查,对天然水曲柳(Fraxinus mandshurica)直径、树高、侧枝和叶的生长季节周期性及生长周期进行了系统研究,找出了生长发育规律,同时对天然水曲柳林进行了定株定向间伐抚育试验,收到良好效果,可在实践中推广。
Through observing at regular intervals and fixed trees and plot investigating, the seasonal growth periods of diameter, height, lateral shoot and leaflet growth of manchurian ash (Fraxinus mandshurica) were studied and the characters of growth and development were analyzed. Meanwhile, the tending thinning met. hod throngh fixed tree and definite cultivation to the forest were conducted and the result proved to be very positive. The method can be widly used in the forest management.
