摘要
选择黔中地区六种不同岩性发育的土壤,以广玉兰幼树为对象研究不同岩性土壤的基本性质及其对广玉兰幼树生长的影响。结果表明:不同岩性土壤理化性状差异显著,影响了广玉兰幼树的生长;苗高、地径生长差异显著,并随季节变化愈加明显;广玉兰幼树适宜生长在石英砂岩发育的砂质粘壤土上,且成活率较高,在第四纪红色粘土发育的土壤上生长最差。通过研究,旨在加深对喀斯特土壤性状的了解,并为石漠化治理提供参考。
The Magnolia grandiflora saplingsas and the six types of rock in the middle area of Guizhou are chosen to study the different type of soil properties and the effect between the growth of Magnolia grandiflora sapling on the different type of rock soil. The results show that： the soil physics and chemistry character have some differences on the different type of rock, and affects the growth of Magnolia grandiflora saplings significantly; the plant growth also has the remarkable differences, and the seasonal variation is more obvious; the Magnolia grandiflora saplings growth in suitable quartz sandstone on the sandy loam, and high survival rate, growth is the worst in Quaternary red clay soil. The fingdings of the research helps to deepen the understanding of the soil properties in Karst area, and provide reference for the desertification control of rocky desertification.
