FIGURE 5.
Relative abundances of nematode at the genes level in spring (A) and autumn (B) seasons. SR-N0 = straw returning without N fertilizer application; SR-N200 = straw returning with 200 kg ha–1 N fertilizer application; TP-N0 = traditional planting without N fertilizer application; TP-N200 = traditional planting with 200 kg/ha nitrogen fertilizer application.
