| 摘 要： | 以杉木第三代种子园为调查研究对象,在外业调查的基础上,对采集的土壤样品进行了性质测定,并依据种子园砧木定植当年的树高,通过方差显著性分析及LSD多重比较分析,探讨了不同采伐迹地间杉木第三代种子园砧木定植当年生长与土壤的差异性。结果表明:土壤pH在4.2～4.8之间、速效磷含量在6.3～6.7 mg/kg之间、有机质在39～43 g/kg之间、全氮含量在1.5～1.7 g/kg之间的林地较适宜杉木砧木的生长;除速效钾外,油茶套种马尾松幼林改造迹地的各土壤养分含量比其它类型高;各采伐迹地土壤表土层厚度差异不显著;马尾松采伐迹地的砧木高生长最好。综合分析,马尾松采伐迹地与油茶套种马尾松采伐迹地较适宜杉木第三代种子园的建立。

| Abstract: | With the research object of stock growth of the 3rd generation seed orchard of Cunninghamia lanceolata and based on field investigation, the properties of soil samples were determined and the tree height for that year were investigated. With analysis of variance and LSD multiple comparison, the differences between soil nutrients and the growth of young C. lanceolata in different cutting blank were researched. The results showed that they were suitable to growth for C. lanceolata at pH between 4.2-4.8, available P between 6.3-6.7 mg/kg, organic matter between 39-43 g/kg, total N 1.5~1.7 g/kg, except for available K. Soil properties content of Camellia oleifera interplanted young Pinus massoniana plantations were higher than other kinds. The differences of soil topsoil thickness during cutting blank were not significant. The stock growth of young C. lanceolata in cutting blank of P. massoniana was best. The comprehensive analysis results showed that the cutting blank of P. massoniana plantations and C. oleifera interplanted young P. massoniana plantations were suitable to the building of the 3rd generation seed orchard of C. lanceolatca |
