Dynamic analysis of carnation rhizosphere microbial taxa under three states in facility cultivation
设施栽培下香石竹不同植株状态根际土壤微生物类群变化分析

Carnation rhizosphere microbial taxa and their ratios were conducted under the healthy, incident and dead states from facility cultivation base.?The results showed that from healthy to incident and to dead states the total bacteria decreased while the total fungi and the total actinomycetes increased; The ratio of bactieria and fungi (B/F), ratio of bacteria and actiomycetes (B/A) and ratio of aerobes and anaerobes (Ae/An ) could be used as the health index for carnation cultivation, disease prevention and control prediction; If rhizosphere B/F and B/A were lower than,?or Ae/An higher than those of healthy carnation, the risk of wilt disease would occur to carnation.
