混交改造杉木纯林对林下土壤肥力影响的研究进展
Research progress on the effect of mixed plantation on the soil fertility in the forests between Cunninghamia lanceolata and other tree species
摘要
Abstract
Chinese fir(Cunninghamia lanceolata)is one of the most important tree species for the timber use in China.In recent years,C.lanceolata plantations have faced to the severe soil fertility degradation and declining productivity due to unsustainable afforestation.Compared with monocultures,mixed plantations between Chinese fir and other tree species have obvious advantages in terms of stand stability,resistance to diseases and insect pests,improvement of forest productivity,and utilization of multiple benefits of forests.The establishment of mixed-species forests is an ideal way to solve the problems such as the decline of productivity in C.lanceolata plantations.We summarized the research results of mixed forests between C.lanceolata and other tree species from 1985 to 2021 in China,and analyzed the effects of mixed plantation on the soil physical and chemical properties,nutrient cycling,microorganisms,enzyme activities and productivity.It was found that mixed-species plantation could balance the soil micro-ecology and increase the content of soil organic matter,which improved soil fertility and productivity.These results can provide a theoretical basis for changing the current situation of monoculture and realizing the potential ecological benefits of Chinese fir forest.关键词
