Abstract	In agricultural production, biodegradable plastic mulching film (Bio-PMF) has the potential to replace conventional plastic mulching film (CPMF) due to its degradability, but their impacts on soil-crop ecology are controversial. In this study, from 2019 to 2021, effects of CPMF and Bio-PMF on the soil-crop ecology and soil pollution were evaluated on a peanut farm. Compared to the Bio-PMF, an overall improvement in the soil-peanut ecology under the CPMF was observed, including an increase of 10.77 ± 4.8% in peanut yield, an amelioration of four soil physicochemical properties (total P and available P in the flowering stage, total P and temperature in the mature stage), an increase of rhizobacterial relative abundances in class level (Bacteroidia, Blastocatellia, Thermoleophilia and Vicinamibacteria in the flowering stage, Nitrospira and Bacilli in the mature stage) and genus level (RB41 and Bacillus in the flowering stage, Bacillus and Dongia in the mature stage), and an enhancement of soil nitrogen metabolism abilities (ureolysis, nitrification and aerobic ammonia in the flowering stage, nitrate reduction and nitrite ammonification in the mature stage). These preserved soil nutrients and temperature, reshaped rhizobacterial communities, and enhanced soil nitrogen metabolism abilities in the mature stage were obviously correlated with peanut yield under CPMF. However, such remarkable relations were not existed under Bio-PMF. In addition, compared with Bio-PMF, CPMF significantly increased the contents of dimethyl phthalate (DMP), diethyl phthalate (DEP), dibutyl phthalate (DBP) and microplastics (MPs) in soil by 79.93, 44.55, 138.72 and 14.1%, respectively. Thus, CPMF improved soil-peanut ecology and caused serious soil pollution, while Bio-PMF introduced little pollutants into the soil and had little impact on soil-peanut ecology. Based on these, the degradation ability of CPMF or the ecological improvement capacity of Bio-PMF should be improved to obtain the environmentally and soil-crop ecology friendly plastic film in the future.

Abstract	Introduction: Crops influence both soil microbial communities and soil organic carbon (SOC) cycling through rhizosphere processes, yet their responses to nitrogen (N) fertilization have not been well investigated under continuous monoculture. Methods: In this study, rhizosphere soil microbial communities from a 5-year continuous mono-cropped peanut land were examined using Illumina HighSeq sequencing, with an N fertilization gradient that included 0 (N0), 60 (N60), 120 (N120) and 180 (N180) kg hm Results and discussion: The obtained results showed that with N fertilization, soil mineral N (N

Abstract	Peanut (Arachis hypogaea) yield is often reduced by calcium (Ca) deficiency. Ca deficiency of peanut plants is likely to occur in most acidified soils (ASs, pH < 5.5) and some neutral soils (NSs, pH 6.5–7.5) in China. Liming is widely used to supply Ca and increase peanut yield. Nevertheless, the effects of liming on the chemical and microbial properties of peanut soils are still unclear, particularly in soils with different initial pH values. A pot experiment was conducted to investigate the effects of CaO (with application rates of 0, 225 and 450 kg/ha) on the chemical properties and bacterial communities and network structures in AS and NS. Compared with CK (CaO 0), the addition of lime improved the pH as well as the exchangeable calcium (ECa) and total nitrogen (TN) contents of both soils. The peanut yield as well as the available nitrogen (AN), available phosphorus (AP) and exchangeable potassium (EK) contents were also higher in AS treated with lime than in that treated with no lime, while lime application to NS had little effect on the yield and AN and EK contents and even significantly reduced the AP content. Lime amendment, especially for the high lime treatment, significantly increased the α-diversity indexes of AS, while no difference in α-diversity was observed among treatments with different liming rates in NS. A weaker β-diversity response to lime addition was observed in NS than in AS. Lime application strongly altered the bacterial community structure of AS by increasing the relative abundances of copiotrophic taxa (e.g., Saccharibacteria) involved in C and N metabolism and pathogen resistance while reducing the percentages of oligotrophic taxa (e.g., Chloroflexi), which were also related to C and N metabolism. In NS, liming favored the growth of Verrucomicrobia with the potential function of denitrification, while microbial groups related to nitrification (e.g., Nitrospirae) and nitrogen fixation (e.g., Acidobacteria) were weakened under liming treatments. Additionally, network analysis revealed that lime amendment provided a more complex and stable network for AS than for NS. Taken together, the responses of the peanut yield, soil chemical properties, bacterial α-diversity and community composition to lime were stronger and more positive in AS than in NS. Results from this study provide critical data for understanding the influence of liming on soil habitats in main peanut-planting areas in China.

Abstract	Peanut (Arachis hypogaea L.) is an important oilseed and leguminous crop. The effect of various forms of nitrogen (N) fertilizer on peanut N acquisition needs to be evaluated by clarifying the N sources from root system absorption and from root nodule fixation. In this study, four kinds of N fertilizers (CONH₂–N, NH₄⁺-N, NO₃⁻-N, NH₄⁺+NO₃⁻-N, labeled by ¹⁵N isotope) were used to quantify N absorption and N fixation of peanut, as well as, their relationships with peanut root morphological characteristics and root nodule properties. Results demonstrated that peanut of CONH₂–N treatment held the highest N absorption and N fixation amounts, followed by NH₄⁺-N, NH₄⁺+NO₃⁻-N and NO₃⁻-N treatments. Detailly, CONH₂–N treatment significantly increased total root length/surface area (especially for fine root of 0–1.0 mm) and N absorption/fixation amounts, suggested that significant correlations were exist between root length/surface area and N absorption, as well as, between root nodule number/weight and N fixation. In addition, with the increase of total root length of 100 cm/plant and root surface area of 10 cm²/plant, N absorption amount of peanut was separately increased by 10.0 and 8.1 mg/plant. With the root nodule number and weight increased by 1.0 unit/plant and 10 mg/plant, N fixation amount of peanut was increased by 13.0 and 17.2 mg/plant during root nodule development. In general, CONH₂–N is the optimal N fertilizer for peanut growth and development with the highest root N absorption and root nodule N fixation, and was suitable for the rational N management of peanut planting.
