| 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,也是东北地区的重要造林树种。研究了不同育苗密度对水曲柳床播苗木生长的影响,结果表明,当密度达到100株/m^2时,为最优育苗密度,其苗高、地径、主根长、侧根数、生物量最优,有利于优质壮苗的培育。

| Abstract: | This was one of the three precious hardwood species in Northeast China of Fraxinus mandshurica Rupr., and was also an important afforestation tree species in Northeast China. The effects of different seedling density on the growth of seedlings of F. mandshurica were studied in this paper. The results showed that when the density reached 100 plants/m 2, the optimum seedling density was seedling height, ground diameter, main root length, lateral root number and biomass, which was conducive to the cultivation of high-quality and strong seedlings. |
