对棉花抗、感枯萎病品种在春播和夏播的2～3叶期、6～7叶期和现蕾期进行了根际真菌区系分析,结果表明:每一品种都有自己独特的根际真菌区系,抗病品种根际真菌种数多于感病品种,其根际主要优势种是:青霉(Penicillum pps.)曲霉(Asqergillus spp.)等,而感病品种则主要是黑根霉(Rhizoqns nigricans)、双胞镰刀菌(Fusarium dimerum)和粘帚霉(Clocladium spp.)等。抗、感品种这种差异在现蕾期比2～3叶期和6～7叶期、在夏播比春播有所减小。播期和生育期对根际真菌区系组成也有较大影响。
The floristic analysis of rhizosphere fungi of resistant and fusarium wilt cultivars in spring and summer sowing at 2 ~ 3 leaf stage, 6 ~ 7 leaf stage and budding stage showed that each variety had its own unique root Among the fungi, the number of fungi in the rhizosphere of the resistant fungi was more than that of the susceptible ones. The main dominant species in the rhizosphere were Aspergillus spp. And the susceptible cultivars were mainly black Rhizoqns nigricans, Fusarium dimerum and Clocladium spp. And the like. The difference of resistance and susceptible varieties in the budding period than the 2 ~ 3 leaf stage and 6 ~ 7 leaf stage, in summer sowing than spring sowing reduced. Sowing date and growth period had a great influence on the composition of rhizosphere fungi.
