对比试验结果表明,甲壳素单独使用、甲壳素与放线菌混合使用、甲壳素与放线菌和枯草杆菌混合使用灌根,对仙客来枯萎病均具有明显的防治效果,仙客来成活率显著提高,其防效与常用化学农药相当。同时对仙客来的生长发育均有促进作用。处理后根的数量、根系的鲜重和干重均有显著增加,并使叶片数增多,冠径增大。此外,单独使用甲壳素还使土壤中放线菌数量明显增加。 The results of the comparative tests showed that chitin alone, mixed with actinomycetes chitin, actinomycete and actinomycetes Bacillus subtilis mixed use of irrigation root, the cyclair wilt disease have significant control effect, cyclamen survival The rate was significantly improved, its control efficiency and chemical pesticides quite common. Cyclamen at the same time both the growth and development have a catalytic role. After treatment, the number of roots, root fresh weight and dry weight were significantly increased, and the number of leaves increased, the crown diameter increased. In addition, the use of chitin alone also significantly increased the amount of actinomycetes in the soil.
