摘要
对6年生杉木与枫香不同混交模式林分及纯林的生长量和土壤养分变化的调查测定与分析,结果表明:杉木、枫香混交种植对杉木幼林生长有正面效应,其中2杉1枫混交的杉木幼林生长量相对最高,平均树高、胸径分别较杉木纯林提高7.14%、7.05%;营造杉木与枫香混交林在一定程度上可改善原杉木林地的土壤肥力。
The study took the six-year-old mixed forests of Cunninghamia lanceolata and Liquidambar formosana and pure forests in Shaowu,Fujian as the research objects,and studied the growth differences and soil nutrient changes of different forest stands after the mixed forests of C.lanceolata and L.formosana.The results showed that the mixed forests of C.lanceolata and L.formosana can promote the growth of C.lanceolata saplings,among which the growth of C.lanceolata in the mixed forest model of C.lanceolata 2:L.formosana 1(2:1)was higher.Compared with the pure C.lanceolata forests,the average tree height and average breast diameter increased by 7.14%and 7.05%respectively.At the same time,the mixed forest of C.lanceolata and L.formosana can significantly improve the soil fertility of the original C.lanceolata forest.
