【摘要】 研究雷州半岛不同土地利用方式对过氧化氢酶活性的影响及过氧化氢酶活性与化学性质的关系,结果表明:①不同土层对过氧化氢酶活性无显著影响;②不同土地利用方式对5~10 cm土层的过氧化氢酶活性具有显著影响;③不同土地利用方式下过氧化氢酶活性与大部分土壤化学性质显著相关,过氧化氢酶活性可作为评价土壤肥力状况的指标,为指导当地合理施肥提供依据;④土壤pH、有机质、速效P、碱解N、全N是影响过氧化氢酶活性的主要因素。更多还原

【Abstract】 The relationship between soil catalase activity and soil chemical under different land use patterns in Leizhou Peninsula was researched. The results showed that:( i) no significant effect on soil catalase activity was observed on different soil layer;( ii) different land use patterns had a significant impact on catalase activity of 5- 10cm layer;( iii) soil catalase activity was significantly associated with most of the soil chemical properties under different land use patterns,so catalase activity can be used as the evaluation index of soil fertility status to provide the basis for guiding the local rational fertilization;( iv) soil pH,organic matter,rapid available phosphorus,alkalized nitrogen and total nitrogen were the main influencing factors of soil catalase activity.更多还原
