中文摘要：研究了不同浓度( 0，5，10，15，20，50，80mg/L)Pb2+胁迫对大薸超氧化物歧化酶、硝酸还原酶、过氧化物酶、过氧化氢酶等保护酶活性的影响。

The results showed that the activities of catalase, ascorbate peroxidase, peroxidase and dehydroascorbate in apoplast of cucumber leaf inoculated with Sphaerotheca fuliginea were significantly increased, but the activities of superoxide dismutase was obviously decreased; Silicon can remarkably increase the activities of APX, SOD, POD and DHAR and decrease the activity of CAT.

结果表明，诱导接种后，质外体中过氧化氢酶、抗坏血酸过氧化物酶、过氧化物酶及脱氢抗坏血酸还原酶活性显著升高，超氧化物歧化酶活性明显降低；加硅显著提高了APX， SOD， POD和DHAR的活性，降低了CAT活性。

Soil physical properties(Water saturated content、Field capacity、Capillary porosity、Non-capillary porosity、The total porosity) The number of micro-organisms(bacteria,fungi and actinomycetes)、activity of the enzyme and nutrient content (Organic matter、TN、AN、P、AP) In the two types of landscape are reflected in the type of surface(0-20cm) higher than the sub-surface(20-40cm).

2土壤物理性质(饱和含水量、田间持水量、毛管孔隙度、非毛管孔隙度、总孔隙度)、微生物数量、酶活性(过氧化氢酶、脲酶和蔗糖酶)及养分含量(有机质、全氮、有效氮、全磷、速效磷)在不同景观及其界面中均表现为表层(0-20cm)高于亚表层(20-40cm)。

Soluble protein content, the superoxide dismutase, peroxidase, ascorbate peroxidase and catalase activities.

的变化以及超氧化物酶、过氧化物酶、过氧化氢酶和抗坏血酸过氧化物酶的活性的变化。
