| 英文摘要 | The impact of long-term application of fertilizers in soybean fields on soil nematode community structure was studied. the long-term application model of fertilizers lasted 13 years in a soybean-wheat-corn rotation, and included three treatments: no fertilizer (nf), chemical fertilizer (urea and ammonium phosphate, cf), and pig manure combined with chemical fertilizer (mcf). the soil nematode community structures and ecological indices were determined from soil samples taken at five soybean growth stages from may to october in the soybean phase of the rotation. fertilizer application had significant effects on abundance of plant parasites, bacterivores and fungivores (p < 0.05), but had no significant effects on total nematodes and omnivores-predators. abundance of plant parasites was higher in nf than in mcf and cf:, and abundance of bacterivores was highest in mcf. fertilizer application significantly affected plant-parasitic nematode maturity index (ppi) and nematode channel ratio (ncr) ecological indices (p < 0.05). shannon-weaver index (h') and species richness (sr) indices were higher in mcf than in either nf or cf. the abundances of total nematode and plant parasites showed increasing trend with soybean growth in all three treatments. this is probably due to soil environment being more suitable for soil nematode survival with more food available for plant parasites as the soybean grows. soybean growth stage significantly affected the h', free living nematode maturity index (mi) and ppi. bacterivores significantly correlated with soil nutrient status suggesting that they could be used as a potential indicator of soil fertility.
