接种丛枝菌根对木薯华南5号生长的影响

摘要

[Objective]The influence of VAM fungi on growth of cassava ( Manihot esculenta) was studied. [ Method] Different inoculation methods of two fungi were compared by field inoculation trials. [ Result] Glomus intraradices bad higher and stable infective ability ,but the contribution to the growth of cassava was low. Inoculation with Glomus manihotis had beneficial effects for the early growth stage of cassava. The mixture inoculum Glomus intraradices + Glomus manihotis increased cassava yield probably because it could put off the abscission period of cassava. [Conclusion] Mixed inoculation had better effects on growth of cassava.%[目的]研究茵根茵接种剂对木薯生长的影响.[方法]应用大田试验法,对2种茵根茵的不同接种方法进行比较.[结果]Glomus intraradices菌种对木薯有较强和较稳定的侵染力,但对木薯生长贡献不大；Glomus manihotis菌种时木薯早期生长效果较好；双接种茵根真菌Glomus intraradices和Gtomus manihotis能有效推迟木薯的落叶期,对木薯产量有较好的作用.[结论]混合接种对木薯生长效果较好.
