摘要
以福建省南平市葫芦山国有林场为例,调查研究了杉木与楠木套种下土壤物理性质的变化及套种对杉木生长的影响。结果表明,套种降低了土壤容重,并且使土壤非毛管孔隙度和土壤最大持水量分别增加了76.2%和13.3%,有效地改善了土壤的物理性质。此外,套种增加了杉木的胸径并且使杉木的蓄积量增加了21.5%,对杉木生长有积极的影响。
Interplanting is one of the important measures to improve the soil physical properties of Chinese fir(Cunninghamia lanceolata)plantation and maintain the sustainable development of Chinese fir plantation.In this study,Hulushan State Forest Farm in Nanping City,Fujian Province,China was taken as an example,the effect of interplanting Phoebe nanmu with Chinese fir on soil physical properties and the growth of Chinese fir were investigated.The results showed that interplanting reduced soil bulk density and increased soil non-capillary porosity and soil maximum water holding capacity by 76.2%and 13.3%,respectively,effectively improving soil physical properties.In addition,intercropping increased the accumulation of Chinese fir by 20.6%,which had a positive effect on the growth of Chinese fir.
