Abstract:
In order to analyze the characters of soil nematode community in greenhouse 12 years history,and to assess the status of soil health in greenhouse,the community of soil nematode was investigated to reveal the diversity of soil nematode community,plant parasite index （PPI) and mature index （MI) by soil nematode 18S rDNA clone library.The results showed that the dominant soil nematode group of 12 years greenhouse were bacterial-feeding nematodes with percents of 59.4%,followed by plant parasitic nematode with percent of 34.9%.At genus level,Meloidogyne was the predominant nematode groups represented 31.5%,followed by Rhabditoides with 28.8%.Moreover,the PPI and MI of soil nematode community in 12 years greenhouse were 1.11 and 1.86,respectively.In a conclusion,plant parasitic nematode possessed high percentage in soil nematode community,suggesting that soil was disturbed by farm operation and structure of soil nematode community disorder.On the whole,health of soil in greenhouse was abnormal.
