| 摘 要： | 目的]探索长孢直喙镰孢霉引起的丽江山慈菇鳞茎腐烂病的新型防治方法。方法]研究了8种金属离子对该病原菌生长的影响,并测定了丽江山慈菇根际土壤和鳞茎中7种金属元素的含量。结果]当Cu2＋和Mg2＋浓度大于1.0 mg/L、Zn2＋和Ca2＋浓度小于0.5mg/L时,可显著抑制病原菌生长。丽江山慈菇鳞茎在生长过程中可高度富集K,富集Zn和Mg,限制吸收Ca和Fe,抑制吸收Cu和Mn。结论]含Mg元素的微肥可用于防治丽江山慈菇鳞茎腐烂病。

| Abstract: | Objective]The new control methods of the bulb rot of Iphigenia indica Kunth.caused by Fusarium orthoceras App.et Wr.var.longius(Sherb.) were explored.Method]The effect of eight different kinds of metal ion on the pathogen was studied;the contents of seven different kinds of metal ion in rhizosphere earth and bulb were also determined.Result]The results showed that when the concentration of Cu2+ or Mg2+ was higher than 1.0 mg/L or the concentration of Zn2+ or Ca2+ was lower than 0.5 mg/L,the growth of pathogen could be restrained.The results also showed that the bulb could enrich K highly,enrich Zn and Mg,limit the absorption of Ca and Fe,and inhibit the absorption of Cu and Mn during the growth process of bulb in Iphigenia indica Kunth.Conclusion]Micronutrient fertilizer containing Mg could be used to prevent and cure the bulb rot of Iphigenia indica Kunth. |
