为探讨丛枝菌根真菌作为薯类作物菌肥应用的可行性,以木薯作为供试作物进行优势菌肥的筛选,并研究其对菌根感染率和生长的影响。应用盆栽试验法,研究了3种AM菌种,包括根内球囊霉Glomus intraradices(Gi)、木薯球囊霉G.manihotis(Gm)和疣状无梗囊霉Acaulospora tuberculata(At)在单菌接种和混合接种条件下对木薯(Manihot esculenta)’华南205号’生长的影响。初步研究结果显示,单菌接种处理中,Gm对木薯有较高的感染频率,菌根的形成对木薯的株高生长及茎的P含量吸收有较好的促进作用;Gi和At处理组对木薯的生长促进作用不明显。总体来说,混合接种处理2G和2G+At对木薯生长的促进作用优于单菌接种,2G...

To investigate the possibility of using arbuscular mycorrhizal fungi on tuber crops culture,experiments were conducted with cassava as test crop to screen the advantageous fungi and to study the effects of AM fungi on the infection rate and the growth of cassava.The effects of AM fungi,including Glomus intraradices（Gi）,G.manihotis（Gm） and Acaulospora tuberculata（At）,on the growth of cassava by the pot culture method with single inoculum treatments and mixed inocula treatments were studied.The results showed that there was higher infective...
