- 摘要:
- 以枸杞为试材，通过盆栽试验，调查了从枸杞根际和根表分离的褐球固氮菌和土壤红球菌2种固氮菌对枸杞生长发育和果实性状的影响，并对试验苗木的生长量、果实大小和生理生化指标进行测定。结果表明：褐球固氮菌的接种可促进游离脯氨酸在枸杞叶片内累积；褐球固氮菌和土壤红球菌的单一接种处理则可降低枸杞叶片中的丙二醛（MDA）含量；土壤红球菌的接种可以促进枸杞生长，增加枸杞叶片的叶绿素含量并提高枸杞果实平均单果重，较适宜于在枸杞栽培上应用；土壤红球菌和褐球固氮菌的混合接种没有表现出预期的协同作用。
- Abstract:
- Taking wolfberry as test material，the inoculating effect of two kinds of azotobacter，Rhodococcus zopfii and Azotobacter chroococcum which were screened from root soil and root surface of wolfberry，on wolfberry was investigated by pot experiment.By comparing and analyzing on the growth，fruit size，and physiology indicators.The results showed that Azotobacter chroococcum inoculating could promote free praline accumulating in the leaves of wolfberry.Azotobacter chroococcum or Rhodococcus zopfii inoculating can decrease MDA content in the leaves of wolfberry. Rhodococcus zopfii inoculating could increase chlorophyll content in the leaves of wolfberry，improve average fruit weight.It could be used in wolfberry cultivation optimumly. The combined inoculation of Azotobacter chroococcum and Rhodococcus zopfii had no synergistic reaction.
