摘要:
为探索小麦不同生长时期根际土壤微生物数量的动态变化规律,通过稀释分离法分析健康植株和患病植株根际土壤真菌、细菌和放线菌数量。结果表明,患病植株根际土壤真菌种群数量在小麦不同生长时期比健康植株根际土壤真菌数量多,从返青期到成熟期,真菌种群数量逐渐增加,孕穗期达到最大值,健康植株根际土壤真菌数量为 10.21×103 CFU/g,患病植株根际土壤真菌数量为14.27×103 CFU/g。患病植株根际土壤细菌、放线菌数量在小麦不同生长时期比健康植株根际土壤细菌、放线菌数量少,从返青期到成熟期,种群数量逐渐增加,在扬花期达到最大值,健康植株根际土壤细菌数量为50.78×106 CFU/g,放线菌数量为28.44×103 CFU/g,患病植株根际土壤细菌数量为36.68×106 CFU/g,放线菌数量为22.67×103 CFU/g。因此,小麦茎基腐病的发生与根际土壤微生物数量有一定的关系,其中当真菌数量较多,细菌和放线菌数量较少时,有可能加重病害的发生。
