闽北山地杉木-厚朴混交林生长状况及土壤理化性质研究
|
摘要
在三明市三元区开展了杉木与厚朴比例分别为1∶1、2∶2和3∶3的行状混交试验,通过对19年生试验林进行调查分析,结果表明:杉木与厚朴混交对杉木的生长起到了促进作用;杉木与厚朴混交改善了土壤结构;杉木-厚朴混交林土壤肥力状况优于杉木纯林,杉木与厚朴混交提高了土壤肥力;杉木与厚朴按照3∶3的比例行状混交效果最好。
In the Sanyuan District of Sanming City, line mixture experiments of Cunninghamia lanceolata and Magnolia officinalis with the ratio being 1∶1, 2∶2 and 3∶3 were conducted. Through investigation of the 19-year-old experimental forest, result shows that: The mixed forest of Cunninghamia lanceolata & Magnolia officinalis promote the growth of Cunninghamia lanceolata; the mixed forest of Cunninghamia lanceolata & Magnolia officinalis improve soil structure; the soil fertility of Cunninghamia lanceolata & Magnolia officinalis mixed forest is optimal than that of pure Cunninghamia lanceolata, and the mixture of Cunninghamia lanceolata & Magnolia officinalis increase soil fertility; the effect of line mixture of Cunninghamia lanceolata & Magnolia officinalis with the ratio being 3:3 is optimal.
