肥料施入土壤后,会对酶活性产生一定的影响,进而影响土壤的生态和土壤质量。以河北平山片麻岩及花岗岩山地贫瘠土壤为研究对象,通过施用3种新型肥料后探究土壤各种酶活性在不同肥料之间差异性。结果显示,土壤蔗糖酶、过氧化氢酶、酸性磷酸酶、中性磷酸酶活性均有所提高,脲酶活性降低,其中生物有机肥对脲酶的抑制作用最强,微生物菌肥对脲酶的抑制最弱。 Fertilizers applied to the soil, the enzyme activity will have a certain impact, thereby affecting soil ecology and soil quality. Taking Pingshan of Hebei and gneissic and barren soil of granite as research object, the differences of various enzyme activities in soil between different fertilizers were explored by applying three kinds of new fertilizers. The results showed that the activity of soil invertase, catalase, acid phosphatase and neutral phosphatase were increased, and the urease activity was decreased. Among them, the bio-organic fertilizer had the strongest inhibitory effect on urease, and the inhibition effect of microbial fertilizer on urease weak.
