拟赤杨杉木混交林培肥土壤的研究

Study on Soil Fertility in Chinese Fir Plantation Mixed with Alniphyllum fortunei

对11年生拟赤杨纯林、拟赤杨杉木混交林和杉木纯林土壤肥力的研究结果表明：拟赤杨杉木1：3混交林具有良好的培肥土壤能力，同时土壤结构体破坏率、团聚体、水稳性团聚体、土壤结构系数、土壤孔隙度和通气度也表现最好；其次是拟赤杨纯林，最差是杉木纯林．可见拟赤杨杉木1：3混交林可在我省山区推广应用．

The soil fertilities of three kinds of plantations were measured, those were pure 11-year Alniphyllum fortunei plantation, pure if-year Chinese fir plantation and if-year Chinese fir plantation mixed with Alniphyllum fortunei. The measures showed that the mixed forest has a better fertilizing ability than the others, its physical and chemical properties being superior to the others, the pure Alniphyllum fortunei plantation is the second. For this case, the Chinese fir plantation mixed withAlniphyllum fortunei is worth popularizing to plant in Fujian province.
