“…In our study, there was no significant difference in paddy yield between two treatments, which was inconsistent with Lu et al. (2018), who reported that rice–rape rotation increased the rice yield significantly. Different soil nutrient level (in our study and the reference, SOM contents were 28.84 and 3.41 g kg –1 , respectively) may lead to the difference of effects of green manure on crop yield.…”

“…First, deep plowing in our experiment was combined with rice straw returning, supplemented with a lot of organic substrates, which could promote the microbial community (Chen et al., 2017); second, compared with the no tillage in the reference, deep plowing could bring more storage spaces for SOC‐rich material and oxygen (Alcántara et al., 2016), and was more conducive to the growth of soil microorganisms. Different rotations exerted a significant effect on bacterial community, which is similar to some previous study (Gao et al., 2015; Lu et al., 2018). However, fungal community was less affected by the rotation modes.…”

Rice (Oryza sativa L.)–fallow and rice–green manure rotation are two common ecological rotation modes in the Lower reaches of the Yangtze River Basin. In this study, based on a long‐term positioning field experiment, soil microbial community structure (bacteria and fungi) and physicochemical properties were investigated and compared to comprehensively evaluate the effects of rice–fallow (RF) and rice–bean (Vicia faba L.) (green manure, RB) rotation on soil health, thus providing scientific basis for the utilization mode of paddy field in winter. The results showed that (a) compared with RF, the contents of soil organic matter (SOM), humic acid (HA), total N, and soil alkaline phosphatase in RB were significantly enhanced by 33.84, 71.04, 35.48, and 54.38%, respectively (p < .01); available K content in RF was increased by 22.84% compared with RB (p < .01); (b) the soil macroaggregates with a diameter more than 0.25 mm (R0.25), mean weight diameter, and geometric mean diameter (GMD) in RB treatment were significantly higher than those of RF by 112.67, 60.25, and 64.88%, respectively (p < .05); (c) different rotations altered bacterial community structure significantly, but exhibited less effect on that of fungi; bulk density, pH, GMD, SOM, and HA were the key environmental factors shaping the bacterial and fungal community structure. The alteration of specific bacterial and fungal taxa revealed that RB had a more promising potential to promote crop growth and improve organic matter decomposition. Therefore, rice–green manure rotation demonstrated a stronger positive effect on soil physicochemical and microbial properties.

“…Furthermore, it activates the plant defense mechanisms against different bacterial and fungal pathogens ( Mukhtar et al, 2019 ). Thus, the composition of rhizosphere–soil microbial communities plays an important role in the stability of plant, soil, and rhizosphere microbial communities ( Lu et al, 2018 ). Further, syringic acid reportedly changes the community composition of bacteria and fungi in the cucumber rhizosphere, which may negatively impact the growth of cucumber seedlings by inhibiting the growth of plant-beneficial microorganisms ( Wang et al, 2018 ).…”

Meloidogyne incognita is one of the most destructive soil pests, causing serious economic losses in tomato production. Here, in vitro experiments demonstrated that the Bacillus licheniformis strain JF-22 has the potential to prevent M. incognita infection. A pot experiment confirmed that B. licheniformis strain JF-22 isolated from the tomato rhizosphere soil and planted in the tomato root-knot nematode disease area effectively prevented and controlled M. incognita, reducing its negative effect on tomato growth. Additionally, the composition of volatile substances secreted by B. licheniformis strain JF-22 was analyzed using solid-phase microextraction and gas chromatography–mass spectrometry. We detected acetoin, 2,3-Butanediol, [R-(R*,R*) ]-, and hexamethyl cyclotrisiloxane as the main components among these volatiles. Using MiSeq sequencing technology and bioinformatics, we analyzed the influence of B. licheniformis strain JF-22 on the microbial community of the tomato rhizosphere. B. licheniformis strain JF-22 changed the composition of the microbial community; particularly, it significantly reduced the diversity of the fungal community. Furthermore, using the FUNGuild and PICRUSt databases, we predicted the effect of JF-22 on microbial community function. In conclusion, B. licheniformis strain JF-22 may be considered as a potential biocontrol agent against M. incognita.

“…However, previous studies have suggested that excessive chemical nitrogen (N) fertilization may cause acidification of soil, further leading to the degradation of soil fertility (Mi et al., 2018; Pernes‐Debuyser & Tessier, 2004). Soil microorganisms have a significant role to regulate nutrient cycle and energy flow in farmland ecosystems (S. Lu et al., 2018). They can quickly perceive and respond to changes of soil characteristics caused by N application.…”

Plastic film mulching (PM) cultivation is an important measure to alleviate the seasonal shortage of water resources. Long‐term nitrogen (N) fertilization under PM cultivation may be more conducive to enhance the ecological relationship between microbial communities involved in nutrient cycling. In this study, the effects of long‐term application of chemical N fertilizer (common prilled urea [PU]) or no N fertilization on the microbial community composition under the traditional flooding (TF) cultivation and PM cultivation were comparatively analyzed. The results demonstrated that water regimes had significant effects on all soil properties except alkali‐hydrolyzable N. Compared with TF cultivation, PM cultivation increased pH and available phosphorus (AP) by 1.14 and 13.67%, respectively, and decreased organic matter and available potassium (AK) by 6.07 and 8.39%, respectively. Nitrogen fertilization levels had significant effects on soil AP and AK, with increases of 1.39 and 1.82 mg kg−1 in PU treatment compared with CK, respectively. Neither water regime nor N fertilization level had a significant influence on soil microbial richness (Chao index) and diversity (Shannon index). However, water regimes played critical roles in driving microbial community changes. Network analysis showed that the microbial community had nonrandom co‐occurrence pattern. Myrmecridium, Defluviicoccus, Emericellopsis, Pseudarthrobacter, and Syntrophorhabdus were the keystone taxa. A higher relative abundance of Defluviicoccus, Emericellopsis, and Syntrophorhabdus was observed in the CKPM treatment, and a higher relative abundance of Myrmecridium and Pseudarthrobacter was observed in the PUPM treatment. Therefore, PM cultivation is an effective measure to improve potential beneficial taxa of soil microbial communities.
