摘要: 对松嫩平原西部盐碱草地土壤多酚氧化酶活性及其与主要肥力因子的关系进行研究,结果表明,在植被生长季各月份内,多酚氧化酶活性在不同地段的变化有一定的规律性,都表现为碱斑裸地及植被生长较差的地段酶活性较高,而植被生长茂盛的地段酶活性低,但不同地段多酚氧化酶活性的季节变化规律不同;除钾素外,多酚氧化酶活性和肥力因子间都有显著或极显著的相关关系,全盐对酶活性的直接效应最大,且通过全氮、速效磷、有机质、pH值的间接效应也较大,是影响酶活性的重要因素;主成分分析表明,可以用多酚氧化酶活性来指示土壤全盐、pH值、全氮、速效磷和有机质的变化。

Abstract: Polyphenol oxidase (PPO) activity and its relationship to the main soil fertility factors in west Songnen alkali grassland were examined. PPO activity was higher in bare and sparse vegetation spots, but lower in lush vegetation spots. The seasonal dynamics of PPO activity varied in different spots. PPO activity was highly correlated with fertility factors except for potassium nutrition and the most important factor was total salt. PPO activity could be used to show changes of total salt, pH value, total N, available P and organic matter.
