通过田间及盆栽试验结果表明，棉花枯萎病菌抑菌性土壤施入不同形式的有机肥后，抑菌性发生了变化。施入马粪后，抑菌性被削弱，枯萎病菌增殖加快，棉花枯萎病发病率与导菌土相当，而施入棉子饼及豆饼之后，则抑菌性增强，抑菌效果增加，尖胞镰刀菌萎蔫专化型的增殖受到抑制，而非致病性镰刀菌及产荧光假单胞菌含量增加 The results of field and pot experiments showed that the antibacterial activity of Fusarium oxysporum f. Sp. Was changed after the different types of organic fertilizers were applied. After the application of horse manure, the antibacterial activity was weakened and the Fusarium oxysporum multiplication accelerated. The incidence of cotton fusarium wilt was similar to that of the fungus soil. However, the application of cotton seed cake and soybean cake increased the antibacterial activity and the antibacterial effect, Fusarium solani special type of proliferation was inhibited, but not pathogenic Fusarium and Pseudomonas fluorescens content increased
