英文摘要Aim of the present research is to investigate the effect of nitrogen (N) and phosphorus (P) on soil food webs (microbes, nematodes and microarthropods) trophic interactions in agriculture ecosystems. A complete randomized block design experiment of N and P fertilization was initiated in 2010 with four treatments: (1) P-addition, (2) N-addition, (3) NP-addition and (4) control. After 4years of fertilization, compared with control, N-addition had a negative effect on microarthropods and clarify indirectly by significantly (P<0.05) increasing soil total nitrogen (0.37g kg(-1)) and available nitrogen (20.03mg kg(-1)). The reduction in microarthropods resulted significant (P<0.05) increase in bacterivores and fungivores feeding on bacteria and fungi, an example of top-down control. P-addition had indirect negative effects on microarthropods by means of significantly (P<0.05) increasing soil total phosphorus (0.62g kg(-1)) and available phosphorus (24.17mg kg(-1)), aggravated fungivores feeding on fungi and strengthened top-down control. NP-addition significantly (P<0.05) increased total microbial biomass, nematodes and microarthropods and resulted in bottom-up control. These results suggested that top-down effects were the dominant force in N- or P-addition treatments. NP-addition strengthened bottom-up control by enriching food resource. Unbalance fertilization could pose adverse on agricultural soil ecosystem and yield potential of crops.
