楠木人工林土壤肥力研究

对26年生楠木人工林和杉木人工林生物量及土壤肥力进行调查,以研究楠木人工林培肥土壤功能,结果表明:营造楠木人工林后林地土壤水稳性团聚体含量增加,团聚体的稳定性增强,容重降低,总孔隙度增加,林地土壤结构状况、孔隙、水分和养分状况均得到不同程度的改善,楠木人工林比杉木能更好地培肥土壤。

Study of Soil Fertility of Phoebe bournei Planted Forest

The biomass and the soil fertility of 26 years planted forest of Phoebe bournei and Cunninghamia lanceolata were carried on the investigation, studies Phoebe bournei planted forest to cultivate the fat soil function, results indicated: After building Phoebe bournei planted forest, the forest land holard stable coacervate content increased, the coacervate stable enhancement, the bulk specific gravity reduced, the gross porosity increased, the forest land soil structure condition, the hole, the moisture conte...
