| 摘 要： | 土壤酶活性能够实质性的反映土地管理和土壤健康状况。为了更好的了解复合农林模式中土壤酶活性的变化规律和功效,本研究对花椒（Zanthoxylum bungenum）模式、桃树（Prunus persica var.nectariana）模式、桑树（Morus alba）模式和梨树（Pyrus pyrifolia）模式根际与非根际土壤酶活性与土壤养分进行了对比分析。结果表明：由于在林下广泛种植多年生黑麦草（Lolium perenne）,使得木本植株根际与非根际土壤酶活性没有显著的差异,但它们的活性都远远高于其对照地。除各模式多酚氧化酶活性的峰值均出现在9月份外,过氧化物酶、蔗糖酶、磷酸酶、脲酶的峰值多出现在7月和8月份。有机质与这5种土壤酶活性都有显著的正相关,而全N仅与磷酸酶和蔗糖酶有显著的正相关,pH值则与它们呈显著的负相关。植物组成可能对土壤酶活性和土壤化学性质有直接的影响。 |

| Abstract: | Soil enzyme activities can provide an assessment of these changes which are essential for soil management and soil health.To better understand the roles of enzyme activity and efficiency,the enzyme activity and nutritents of the rhizosphere and non-rhizosphere soils were analyzed in agroforestry systems,i.e.Zanthoxylum bungenum model,Prunus persica var.nectariana model,Morus alba model and Pyrus pyrifolia model.The results showed that no significant difference of enzyme activity was found between the rhizos... |
