Green manuring increases network complexity and deterministic assembly of diazotrophic community in a subtropical paddy soil

we conducted an eight-year rice-rice-green manure rotation and straw return experiment in southern China to assess the effects of green manuring and straw return on diazotrophic communities at various rice growing stages.本研究在中国南方开展了一项为期八年的稻-稻-绿肥轮作还田试验，以评估绿肥还田与秸秆还田对不同水稻生育期固氮微生物群落（diazotrophic communities）的影响。
