分别对不同处理的欧洲云杉扦插苗进行强化培育研究,研究结果表明:补光对欧洲云杉的生长有明显的促进作用;1年生扦插苗通过补光的培育,其苗高达到13.7 cm,净生长量平均达到8.2 cm,是大田移栽自然生长条件下的173.3%;2 a连续补光的欧洲云杉扦插苗的苗高、当年新稍长、侧枝数分别达到38.19 cm、16.02 cm和24.12个,比不补光分别提高43.6、77.2和71.3个百分点,2 a补光的地上部分和地下部分的干重最大,通过光照处理,可以阻止欧洲云杉的早期封顶,进行二次生长,从而达到出圃的要求。
The results showed that supplemental light had a significant promoting effect on the growth of European spruce. One-year-old cuttage seedlings grew up to 13.7 cm with supplemental light, Net growth reached an average of 8.2 cm, which was 173.3% under natural growth conditions in field transplanting. The seedling height of European spruce cuttings with 2-year continuous light compensation was 38.19 cm and 16.02 cm 24.12, respectively, increased by 43.6,77.2 and 71.3 percentage points than the non-light, 2 a fill light aerial parts and underground parts of the largest dry weight, by light treatment, can prevent the early European spruce cap, secondary growth, To achieve the requirements of nursery.
