Control Effects of Several Metal Ions in Micronutrient Fertilizer on the Bulb Rot of Iphigenia indica Kunth.

[Objective] The 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 ions on the pathogen was studied;the contents of seven different kinds of metal ions in rhizosphere soil and bulb were also determined.[Result] The results showed that when the concentration of Cu2＋ or Mg2＋ was greater than 1.0mg/L or the concentration of Zn2＋ or Ca2＋ was lower than 0.5mg/L,the growth of pathogen could be inhibited.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 I.indica Kunth.[Conclusion] Micronutrient fertilizer containing Mg could be used to prevent and cure the bulb rot of I.indica Kunth.

微肥中几种金属元素对丽江山慈菇鳞茎腐烂病的防治研究

[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。

丽江山慈菇鳞茎腐烂病病原生物学特性研究

该实验研究了温度、pH、氮源和碳源对长孢直喙镰孢霉的影响。结果表明：（1）该菌最适生长温度为25~28℃,适宜生长温度为22~28℃,孢子萌发的最适温度为21℃;（2）最适生长pH为7.7~8.7;（3）在所选氮源中,蛋白胨为最适氮源;（4）在所选碳源中,乳糖为最适碳源。

止咳平喘苗药对咳嗽型哮喘的临床疗效

目的研究止咳平喘苗药对治疗咳嗽型哮喘(CVA)的临床疗效。方法收集120例于2010年1月~2012年12月来我院就诊和住院的CVA患者,随机分为对照组和观察组,各60例。对照组患者给予氨茶碱片,观察组患者给予止咳平喘苗药,对比分析两组患者的临床疗效。结果全部病例经2～4周的治疗,对照组的总有效率为60.00%,观察组的总有效率为95.00%;对照组半年内的复发率为51.67%,其中有3例转变为典型哮喘,观察组半年内的复发率为16.67%,没有患者转变为典型哮喘。比较差异有统计学意义(P<0.05)。结论止咳平喘苗药根据苗医理论,采用多种中药制成的方剂,对咳嗽性哮喘疗效显著,值得临床推广。
