Abstract

Plastic mulching is a widely used intensive planting system for cotton production in China. For the present study, the effects of three plastic mulching treatments (i.e., NDNM: normal sowing date with no plastic mulching as a positive control, NDM: normal sowing date with plastic mulching, and LDM: sowing 7 days late with plastic mulching) were studied in the field on seedling disease, Verticillium wilt, and Fusarium wilt as well as on the lint yield in cotton from 2019 to 2020. The treatment effects were evaluated based on the disease incidence (DI) and disease severity index (DSI), seedling fresh weights, lint yields, and yield components. For all cultivars (SCRC28, SCRC21, and Jimian11), both the DIs and DSIs of the seedling disease were lower in the LDM treatment than in the NDNM and NDM treatments. The DIs and DSIs of Fusarium wilt for all the cultivars were higher in the NDNM treatment than in the NDM and LDM treatments. However, the DIs and DSIs for Verticillium wilt were lower in the NDNM treatment. Moreover, the seedling fresh weights, average lint yields, and boll numbers per square meter were all highest in the NDM treatment and lowest in the NDNM treatment. The results of this study demonstrated that the use of plastic mulching with a suitable seed sowing date would be an appropriate cultural practice for enhancing cotton production and reducing the severity of cotton seedling and Fusarium wilt disease.
