【摘要】 通过对杉木林地土壤理化性质的研究,探讨了杉木种植对土壤肥力的影响。结果表明:种植杉木后的林地土壤容重降低、孔隙度增大、田间持水量升高,土壤物理性状得到改善;杉木林地速效氮和速效磷含量处于丰富水平,有机质、总氮和总钾处于中等水平,总磷和速效钾处于贫乏水平。更多还原

【Abstract】 Through the study on the Soil Physic-chemistry Properties in the Chinese Fir plantations, the influence of Chinese Fir planting on the soil fertility was researched. The results show that the soil after Chinese Fir planting bulk density decreasing, porosity increasing, field capacity raising, physical behavior of the soil is ameliorated; the content of the rapidly available Nitrogen and rapidly available phosphorus are rich; organic matter total Nitrogen and total kalium are medium; total phosphorus and rapidly available kalium are paucity.更多还原
