Straw return is a sustainable soil fertility-building practice,which can affect soil microbial ***,how straw return affects arbuscular mycorrhizal fungi(AMF)is not well ***,we studied the impacts of different straw management treatments over eight years on the structure and functioning of AMF communities in a rice-wheat rotation *** straw management treatments included no tillage with no straw(NTNS),rotary tillage straw return(RTSR),and ditch-buried straw return(DBSR).The community structure of AMF was characterized using high-throughput sequencing,and the mycorrhizal functioning was quantified using an in situ mycorrhizal-suppression *** straw management treatments formed unique AMF community structure,which was closely related to changes in soil total organic carbon,available phosphorus,total nitrogen,ammonium,and *** compared with NTNS,RTSR significantly increased Shannon diversity in 0–10 cm soil layer,while DBSR increased it in 10–20 cm soil layer;DBSR significantly increased hyphal length density in the whole ploughing layer(0–20 cm),but RTSR only increased it in the subsurface soil layer(10–20 cm).The mycorrhizal responses of shoot biomass and nutrient(N and P)uptake were positive under both straw return treatments(RTSR and DBSR),but negative under *** community composition of AMF was significantly correlated to hyphal length density,and the latter was further a positive predictor for the mycorrhizal responses of plant growth and nutrient *** findings suggest that straw return can affect AMF community structure and functioning,and farmers should manage mycorrhizas to strengthen their beneficial effects on crop production.

可将热量转化为电能的柔性热电（thermoelectric,TE）材料已广泛应用于可穿戴电子设备和其他柔性设备中。该研究将无机TE柱与热塑性聚氨酯（thermoplastic polyurethane,TPU）结合,组装成柔性条状热电器（thermoelectric generator,TEG）,进一步用于热电织物（thermoelectric fabric,TEF）的织造。采用有限元分析（finite element analysis,FEA）优化柔性TE条的尺寸并评估其性能。FEA的结果显示,TE条的间距对温差、输出电压和内阻有显著影响。当TE条直径为3.5 mm、条间距为2 mm时,可获得最大功率密度,达到3.43μW·cm-2（在温差ΔT=10.5 K的条件下）。在实验条件下,热板接触以及铜线-TE条连接处存在倾斜度,导致所织造的三维TEF的功率密度只能达到模拟结果的29%。尽管如此,在经过450次弯曲测试后,TE条仍展现出优异的柔韧性和稳定的机械性能。这一研究不仅为今后开发更高效的TEF奠定了基础,还为可穿戴式能量采集应用提供了更加舒适、合身的选择方案。
