摘    要:对连续施肥23年的黄泥田土壤酶及土壤养分因子进行了分析,探讨长期不同施肥条件对土壤酶活性及土壤肥力的影响.结果表明,与对照相比,不同施肥制度(化肥、化肥+牛粪、化肥+秸秆回田)下土壤有机质增幅达19.5%~47.1%,氮素增幅达20.6%~47.9%,磷素增幅达36.7%~499.0%,钾素增幅达55.8%~80.0%.施肥提高了土壤脲酶、过氧化氢酶、转化酶和磷酸酶的活性,其中有机无机肥配施增幅达10.3%~28.6%.土壤有机质和养分含量与部分酶活性存在极显著或显著的相关性.表明黄泥田土壤酶活性与土壤肥力密切相关,可作为评价土壤肥力性状的生物学指标.

关 键 词:施肥制度  土壤酶活性  养分  黄泥田

Abstract:In order to explore the effects of long-term fertilizer on the soil nutrient and enzyme activity under different fertilizer application strategies,the soil enzyme and nutrient content were analyzed in the yellow clayey.The results showed that different fertilization regimes ( fertilizer,fertilizer+ cattle manure,fertilizer + straw) could significantly increase the contents of organic matter,total nitrogen,total phosphorus,available nitrogen,available phosphorus and available potassium by 19.5%~47.1%,20.6%~47.9%,36.7%~499.0% and 55.8%~80.0% respectively.Similarly,the soil urease,hydrogen peroxidase,invertase and phosphatase activities were increased by 10.3%~28.6% respectively.In addition,enzyme activities of soil were significantly related to soil nutrients.The results of correlation analysis showed that the activity of soil enzyme could be used as the biological index of soil fertility properties and quality.
Keywords:fertilization regimes  soil enzyme activity  nutrient  yellow clayey soil
