- 摘要:
- 以北美红栎幼苗为试材,采用单因素完全随机区组设计,研究了A1(原土∶蛭石∶泥炭土=1∶1∶1)、A2(原土∶蛭石∶珍珠岩=1∶1∶1)、A3(原土∶蛭石∶泥炭土=1∶1∶1)、A4(原土∶珍珠岩∶泥炭土=1∶1∶1)、A5(原土∶蛭石=1∶1)、A6(100%原土) 6种基质配比下北美红栎容器苗苗高、地径增量和各生物量积累规律,并利用各指标之间的相关性分析和主成分分析进行综合评价。结果表明:6种不同处理对北美红栎容器苗的生长影响差异显著,A3处理的北美红栎容器苗的苗高、地径增量以及全株干重最大,其综合评价得分也最高,达到1.488383,从而筛选出A3处理(原土∶蛭石∶泥炭土=1∶1∶1)是适宜北美红栎容器苗生长的最佳基质。
- Abstract:
- Taking the seedlings of Quercus rubra as material,the effect of six kinds of matrix formulation of A1(original soil∶vermiculite∶peat=1∶1∶1),A2(original soil∶vermiculite∶perlite=1∶1∶1),A3(original soil∶vermiculite∶peat=1∶1∶1),A4(original soil∶perlite∶peat=1∶1∶1),A5(original soil∶vermiculite=1∶1),A6(100% original soil) on growth and accumulation rhythm of height,diameter and biomass of Quercus rubra container seedlings were studied,and using the correlation analysis between each index and comprehensive evaluation on the principal component analysis.The results showed that the ratio of different substrates on Quercus rubracontainer seedling growth impact was bigger,six different ratio of substrate of Quercus rubra had significant influence on the growth of container seedling,A3 treatment,container seedling of Quercus rubra,which the seedling height,ground diameter increment and the whole plant dry weight reached maximum,the comprehensive evaluation score was the highest,reached 1.488383,therefore,the screening of A3 (original soil∶vermiculite∶peat=1∶1∶1) was the most suitable for Quercus rubra container seedling growth.
