土壤酶活性反映了土壤中进行的各种生物化学过程的强度和方向 ,与土壤肥力密切相关。众多研究表明 ,耕作土壤酶活性与土壤肥力因素之间存在显著的相关[1～ 5 ] 。用土壤酶活性作为土壤肥力的指标已受到人们的重视。一些研究结果表明 ,有机肥与化肥配施和单施化肥的土壤中 ,酶活
Soil enzyme activity reflects the intensity and direction of various biochemical processes in the soil and is closely related to soil fertility. Numerous studies have shown that there is a significant correlation between tillage soil enzyme activities and soil fertility factors [1-5]. Soil enzyme activity as an indicator of soil fertility has been people’s attention. Some studies have shown that organic fertilizers and fertilizers are applied and fertilised in the soil alone, with enzyme activity
