为探讨海岸带黑松混交林土壤生化特性及其与土壤肥力的关系 ,该文对 3种类型黑松 (Pinusthunbergii)混交林及纯林的土壤微生物、酶及土壤养分因子进行了测定和分析 .结果表明 :不同林分土壤微生物数量、酶的活性均表现出差异性 ,混交林土壤养分含量均高于纯林 ,尤以黑松×刺槐、黑松×麻栎混交林显著 ;土壤微生物数量、酶活性与土壤养分含量之间呈显著相关关系 ,可作为评价土壤肥力的指标
In order to investigate the relationship between soil biochemical characteristics and soil fertility in mixed stands of Pinus thunbergii and Pinus thunbergii forest, the soil microorganisms, enzymes and soil nutrients of Pinus thunbergii mixed forest and pure forest were measured and analyzed. The results showed that: the quantity of soil microorganism and the activity of enzyme in different stand showed the difference. The content of soil nutrient in mixed forest was higher than that in pure forest, especially in the mixed stands of Pinus thunbergii × Black Locust × Quercus acutissima. The soil microbial quantity, There was a significant correlation between activity and soil nutrient content, which could be used as an index to evaluate soil fertility
