Banana is an important cash crop in tropical regions and is severely threatened Soil fertility by Fusarium wilt disease. Little is known about the effects of combined fertilization on rhizosphere soil properties Fusarium wilt and disease suppression in tropical regions in China. In this study, the effects of combined fertilization on Factor analysis rhizosphere soil properties and the development of banana Fusarium wilt disease were assessed based on key Path coefficient analysis components of soil chemical and biological properties. With chemical fertilization (CF) only, the soil urease, SOC and available nutrients contents were increased continuously, while the soil bacterial diversity, pH, and acid phosphatase activities were initially increased, and then decreased with increasing NPK application rate. Under low NPK application rate (25% CF), the OM addition was more effective in increasing soil bacterial diversity, pH, available nutrients, urease and acid phosphatase activities than NPK fertilization only. However, excessive OM addition had negative effect on soil available P and K content under high NPK application rate (100% CF). The T6...
