通过观测掌握了华北落叶松一年内的生长节律,对影响生长节律的气象因子作了典型相关分析。结果表明华北落叶松生长节律主要受15cm 地温影响,而15cm地温与气温及其它温度因子呈正相关。生长节律为合理确定施肥、抚育时间提供了科学依据。
Through observing and mastering the growth rhythm of Larix principis-rupprechtii in one year, we made a typical correlation analysis of the meteorological factors that affect growth rhythm. The results showed that the growth rhythm of Larix principis-rupprechtii was mainly affected by 15cm soil temperature, while the 15cm ground temperature was positively correlated with air temperature and other temperature factors. The rhythm of growth provides a scientific basis for reasonably determining fertilization and tending time.
