“…The relative abundances of the taxonomic levels of bacterial and fungal phyla and genera between treatments used the "ALDEx2" program package in R to compare and select bacterial and fungal genera (with relative abundances >1% and 0.5% as dominant phyla and genera, respectively) (Fernandes et al, 2014) and analyze differences between rotations with the same/different stubble cress cultivation and the different/same SWCs. The OTUs shared and unique among treatments were counted, and their distributions were illustrated in a Venn diagram with the "Venn Diagram" package in "R" (Yu et al, 2019). Fungal OTUs were assigned to ecological guilds using FUNGuild at the genus and species level (Nguyen et al, 2013).…”

Paddy-upland rotation is an effective agricultural management practice for alleviating soil sickness. However, the effect of varying degrees of flooding on the soil microbial community and crop performance remains unclear. We conducted a pot experiment to determine the effects of two soil water content (SWC) and two flooding durations on the soil microbial community attributes and yield in cucumber. In the pot experiment, cucumber was rotated with cress single (45 days) or double (90 days) under 100 or 80% SWC. Then, the soil microbial were inoculated into sterilized soil to verified the relationship between cucumber growth and microorganisms. The results indicated single cress rotation resulted in a higher cucumber yield than double cress rotation and control. Cress rotation under 80% SWC had higher soil microbial diversity than cress rotation under 100% SWC and control. Flooding duration and SWC led to differences in the structure of soil microbial communities. Under 80% SWC, single cress rotation increased the relative abundance of potentially beneficial microorganisms, including Roseiflexus and Pseudallescheria spp., in cucumber rhizosphere. Under 100% SWC, single cress rotation increased the relative abundance of potentially beneficial bacteria, such as Haliangium spp., and decreased potential pathogenic fungi, such as Fusarium and Monographella spp., compared with double cress rotation and control. Varying degrees of flooding were causing the difference in diversity, structure and composition of soil microbial communities in the cucumber rhizosphere, which have a positive effect on cucumber growth and development.

“…The collective genome of the rhizosphere microbial community is referred to as the second genome of the plant and plays crucial roles in plant growth and health (Berendsen et al, 2012). A growing body of research has demonstrated that replant disease is closely associated with changes in the rhizosphere microbiome (Franke-Whittle et al, 2015;Chen et al, 2017;Yu et al, 2019). Plant roots release variable but substantial amounts of compounds and can shape the rhizosphere microbial community structure (Hu et al, 2018;Stringlis et al, 2018;Voges et al, 2019).…”

“…Chinese farmers have practiced intercropping and rotation for disease control over 2000 years [18,19]. Intercropping, which is defined as the growing of two or more crop species in proximity simultaneously during a growing season, is an agricultural practice that not only increases crop yield and stress resilience, but also reduces the incidence of microbial diseases.…”

Panama disease (Fusarium wilt disease) caused by Fusarium oxysporum f. sp. cubense race 4 (FOC) severely threatens banana (Musa spp.) production worldwide. Intercropping of banana with Allium plants has shown a potential to reduce Panama disease. In this study, six cultivars of Chinese chive (Allium tuberosum Rottler) were selected to compare their differences in antifungal activity and active compounds. Three cultivars Duokang Fujiu 11, Fujiuhuang 2, and Duokang Sijiqing with higher levels of antifungal compounds were further used for intercropping with banana in the pots and field to compare their effects on growth and disease incidence of banana. The six cultivars showed significant differences in antifungal activity against FOC mycelia growth in both leaf volatiles and aqueous leachates. The aqueous leachates displayed stronger antifungal activity than the volatiles. FJH cultivar showed the best inhibitory effect among all six cultivars. Contents of three main antifungal compounds dipropyl trisulfide (DPT), dimethyl trisulfide (DMT), and 2-methyl-2-pentenal (MP) in volatiles and aqueous leachates varied considerably among cultivars. Pot and field experiments showed that intercropping with three selected Chinese chive cultivars significantly improved banana vegetative growth, increased photosynthetic characteristics and yield but decreased disease incidence of Panama disease. Our results indicate that intercropping with Chinese chive shows potential to reduce banana Panama disease and selection of appropriate cultivars is vital for effective disease control.
