| 摘 要： | 应用Li-6400光合分析仪,对不同采伐类型1型(采伐2行落叶松保留2行落叶松)和2型(采伐3行保留3行)的长白落叶松林下人工更新的幼树红松、云杉、北美乔松、白桦的光和特性进行了测定。结果表明,4种幼树的光响应曲线符合三元回归方程模型;各幼树的光补偿点和光饱和点差异不显著;2型中各幼树的表观量子效率的数值好于1型;云杉、红松、北美乔松的光响应曲线最大净光合速率数值,2型均大于1型,白桦则是1型好于2型;云杉、红松、北美乔松的净光合速率日变化曲线是单峰曲线,1型的峰值出现在10:00左右,2型的峰值出现在12:00左右,相同树种同一时刻的净光合速率数值2型好于1型;白桦的净光合速率日变化曲线是双峰曲线,峰值出现在上午10:00和14:00左右,同一时刻的净光合速率数值1型大于2型。

| Abstract: | A study was conducted to determine the photosynthetic characteristics of Pinus koraiensis,Picea koraiensis,Pinus strobes,and Betula platyphylla saplings planted in a Larix olgensis forest under two different cutting styles (cut two rows and leave two rows (type 1) and cut three rows and leave three rows (type 2) ) using Licor-6400. Results showed that the light response curves of the four species of saplings were consistent with the model of ternary regression equation. The light compensation point and ligh... |
