摘要
欧洲花楸实生苗在6年生长过程中,高生长于第3年进入速生期,年生长量达到最高,然后,高生长速度逐年趋于缓慢;全光照处理苗木年平均高生长量明显大于遮阳处理苗木;在有效积温(≥5℃)达到488.6℃时,欧洲花楸苗木高生长开始进入速生期。
The growth process of Sorbus aucuparica seedlings in 6 year, its high growth enter the rapid growth stage in the third year. And the amual growth reach the highest. Then growing speed decline gradually. Annual average high growth of full light treatment plantation is much higher than that of shading treatment.
