Fertilization and clear-cutting effect on greenhouse gases emission of pinewood nematode damaged Masson pine plantation
Introduction Management practices are essential for maintaining forest ecological functions under increasing diseases and pest disasters. The effects of nitrogen fertilization (NF) and clear-cutting (CC) on the soil microbial community structure and greenhouse gases emission were investigated of pin...

NF increased the SMBN but had no significant effect on the SMBC content. The total fungal and bacterial abundances increased in the CC treatment compared with the CK, but there was no significant difference between the NF and CK. The cumulative soil CO2 emission (2.35 t C·hm−2) was higher than that of CK (1.65 t C·hm−2) in summer, and the cumulative annual N2O emission (16.90 kg N·hm−2 yr−1) of NF was approximately 47 times of CK (0.36 t N·hm−2·yr−1).
