- Abstract : through a study on soil aggregate composition , nutrient status and enzymatic activity under mixed forest of chinese fir alniphyllum fortunei and pure stand of chinese fir , the results indicated that , compared to pure stand , the soil structural property was ameliorated , the soil capacity of nutrient supplying and was improved , and the soil enzymatic activity were enhanced
文摘:通过对杉木拟赤杨混交林及杉木纯林土壤团聚体结构、土壤养分状况及酶活性的研究表明，与杉木纯林相比，混交林土壤结构性能得到改善，供肥和保肥能力加强，各种土壤酶活性提高，土壤肥力较好。 - The organic matter influenced > 0 . 25 mm soil particle aggregation and > 0 . 5 mm water - stable soil particle aggregation slightly and played an important role in the aggregation of > 5 mm water - stable soil particles . the percentage of aggregates destruction were remarkably negatively related with content of > 5 mm water - stable soil particle aggregate , and ultimately negatively related with > 0 . 25 mm water - stable soil particle aggregate , which meant the content of water - stable soil particle aggregate dropped as the rise of percentage of aggregates destruction , the loosely fe took a role in increasing content of water - stable soil particle aggregate . the main factor that affecting content of > 0 . 5 mm water - stable soil particle aggregate was percentage of aggregates destruction , whereas organic matter and percentage of aggregates destruction were the dominating matters that influencing content of > 0 . 25 mm water - stable soil particl
粘粒含量在各级团聚体的形成过程中起着一定的作用；有机质对0 . 25mm团聚体、 5mm水稳定性团聚体有一定作用，对0 . 25mm水稳定性团聚体起显著作用；团聚体结构破坏率与5mm水稳定性团聚体成显著负相关，与0 . 25mm水稳定性团聚体达到极显著负相关，说明结构破坏率越大，水稳定性团聚体的数量就越少，反之越多；游离铁含量对促进水稳定性团聚体方面起一定的作用，影响0 . 5mm水稳性团聚体含量主要是结构破坏率，而影响0 . 25mm水稳定性团聚体含量的是有机质和结构破坏率。
