摘要
通过对白皮松人工母树林进行物候观察,从母树林群体和母树单株2个方面揭示了其年物候规律以及所具有的周期性、次序性和关联性等。并分析得出其物候起始日期和起始温度之间、持续天数和≥0℃活动积温之间均呈显著或极显著的正相关关系,对白皮松母树林精准经营和制定良种繁育计划具有重要意义。
Annual phenological regularity and its periodicity,sequence and relevance of parent stand population and parent tree individual were revealed through the phenological observation of the artificial parent stand of Pinus bungeana.Results showed that the relationship between the starting date and the starting temperature of phenological period was significant or extremely significant positive correlation,same as the relationship between continuous days and active accumulated temperature ≥ 0 ℃.This study was important to the precision management of parent stand and the formulation of breeding plans for improved varieties of Pinus bungeana.
