| 摘 要： | 为了探明豆科植物土壤浸提液对马铃薯连作土壤酶活性和电导率影响的差异，以马铃薯品种‘新大坪’为试验材料，研究5种种植方式下3年连作田土壤浸提液和4年豆科植物土壤浸提液对马铃薯连作土壤酶活性和电导率的影响。结果表明：半膜沟播土壤电导率1:1处理的与对照相比降低16.70%，其他处理马铃薯连作土壤的电导率均升高；各处理的过氧化氢酶、碱性磷酸酶和脲酶活性均显著提高，其中1:1处理对平畦覆膜和半膜沟播的过氧化氢酶、碱性磷酸酶和脲酶活性均作用显著，对全膜垄播和全膜沟播的过氧化氢酶和脲酶活性有显著影响；1:2处理对半膜垄播连作土壤过氧化氢酶、碱性磷酸酶和脲酶活性有明显的促进作用，对全膜垄播和全膜沟播的碱性磷酸酶活性作用显著。

Effect of the Legumes Soil Leaching Liquor on Soil Enzyme Activity and Conductivity of Continuous Cropping Potato Soil |
| |
| Abstract: | In order to study the effects of legumes soil leaching liquor on soil enzyme activity and conductivity in continuous cropping potato field, the potato cultivar‘Xindaping’was used as test material, the effects of soil leaching liquor of three years potato continuous cropping field and four years leguminous plants soil under five planting patterns on soil enzyme activity and conductivity in continuous cropping potato field were studied. The results showed that compared with CK, soil conductivity of half-film trench sowing 1:1 treatment decreased 16.70%, soil conductivity of other treatments all showed an increasing trend. The activities of catalase, alkaline phosphatase and urease significantly increased in all treatments, the 1:1 treatment significantly increased those enzyme activities of flat- trench filming and half- film trench sowing, the 1:1 treatment also significantly affected the activities of catalase and urease of whole-film bed planting and whole-film trench sowing; 1:2 treatment could significantly improve the activities of catalase, alkaline phosphatase and urease of half-film bed planting, and it significantly affected alkaline phosphatase activity of whole-film bed planting and wholefilm trench sowing. |
