| 摘 要： | 水曲柳(Fraxinus mandshurica Rupr.)是东北地区三大珍贵硬阔叶用材树种之一,也是东北地区的造林树种.垄作时,水曲柳育苗密度决定苗木的产量和质量,试验结果表明,当密度达到50株/m时,是水曲柳的最优育苗密度,其苗高、地径、主根长和侧根数最优,高径比上的比例比较合适,有利于优质壮苗的培育.

| Abstract: | Fraxinus mandshurica Rupr.is one of the three precious hard broadleaf timber species,and also the major planting tree species in northeast of China.An experiment was conducted to study the effect of different planting density of Fraxinus mandshurica Rupr.on the seedling quality,the resusts showed that quality and production of nursery stock of Fraxinus mandshurica Rupr.were determined by planting density,the seedling height,basal diameter,length of main root,number of lateral root are the best with the opti... |
