摘要
对抗.感枯萎病棉花品种根际微生物数量分折的结果表明,品种抗性与根际微生物之间具有密切关系。抗病品种根际真菌、细菌和放线菌数量都多于感病品种,其中以真菌更加明显。研究结果还表明,播种期和棉株生育期对根际微生物数量也有显著的影响。
There are close relations between the resistance and susceptibility of cottonto wilting and the rhizosphere microorganism quantity.The rhezosphere micro-organism quantity of resistant varieties is more remarkable than that of susce-ptible ones,especially fungi.The sowing time and living stage of cotton havea great influence on the rhizosphere microorganism quantity.
