蜜柚果园施用有机肥与化肥对土壤酶及土壤养分的影响

Effect of applying organic and chemical fertilizer on enzyme activity and nutrition in the soil of pomelo garden

摘要: 对璃溪蜜柚果园进行3a不同施肥定位试验,结果表明,随着施肥年份的增加,施用有机肥和化肥的处理, 其土壤脲酶、酸性磷酸酶、过氧化氢酶及土壤有效养分有提高的趋势,且施有机肥的效果优于施化肥的。相关分析表明,土壤脲酶、酸性磷酸酶、过氧化氢酶、蔗糖酶活性与土壤有机质含量呈显著正相关。

Abstract: The result showed that fertilizer and inorganic fertilizer could increase the soil nutrient content, strengthen the activity of soil enzyme, the effect of organic fertilizer application was better than that of inorganic fertilizer.Correlation analysis indicated that there was extremely significant positive relevant between the activities of soil enzymes and the content of soil organic matter.
