摘要
通过对几种人工杉木混交林进行土壤物理和基本营养元素指标的测定和对比,结果表明:人工杉木混交林在改变土壤物理性质、改变土壤肥力等方面均优于杉木纯林,提倡合理营造杉木混交林。
The results show that mixture plantation is averagely better than pure forests of Cunninghamia lanceolata in aspects of changing soil physics and soil fertility through several artificial mixture forests of Cunninghamia lanceolata over soil physics and nutriation element indicator are determined and compared, therefore, encourage establishing the mixture forests rationally for Cunninghamia lanceolata.
