自然成土过程中土壤养分的变化与植被原生演替常同时发生。随成土年龄变化的植物养分捕获策略(NASs)对植物竞争能力和演替过程具有重要影响。该文将植物NASs划分为细根、微生物、特殊根系、食虫和寄生策略等5个类型;发现植物NASs的多样性随成土年龄的增加呈哑铃型变化模式;特殊根系策略对植物捕获养分的作用在成土中期最小、后期最大,细根和微生物策略的作用随成土年龄的增加逐渐降低;分析了成土过程中NASs对植物种间关系影响的变化,发现NASs对成土早期植物的促进作用和中期的竞争关系具有重要影响,而成土后期多样和互补的NASs对植被群落的稳定共存及多样性的形成具有影响;提出应进一步探究成土过程中土壤养分与植物NASs变化之间的定量关系,开展更多研究以阐明NASs对植被原生演替、物种多样性形成和成土过程的贡献与机理。

Facile construction of Bi2Mo3O12@Bi2O2co. heterojunctions for enhanced photocatalytic efficiency toward NO removal and study of the co.version process

Charge separation and transformation are some of the key requirements for high-efficiency photocatalysis. The photocatalytic reaction mechanism provides a guideline for the development and co.mercialization of high-efficiency photocatalysts. In this study, we designed and favorably synthesized BMO@BOC heterojunctions via a facile solvothermal route and applied the heat treatment method for application in high-efficiency photocatalytic NO removal. More importantly, both co.tinuous stream and intermittent stream methods with in situ diffuse reflectance infrared Fourier transform spectrosco.y were applied to intuitively and dynamically investigate the adsorption process and oxidation process of NO removal over the photocatalyst surface. The intermediate products(NO-, NO2-, and NO2) were explicitly detected in both the adsorption process and oxidation process, whilst the final product(NO3-) appeared only in the oxidation process, owing to the separation, migration, and co.version of photoinduced electron-hole pairs.

co.tinuous cropping obstacles hamper the efficient growth and yield of Szechuan pepper,Zanthoxylum *** current study investigated the impact of different levels of bioorganic fertilizer on the leaf physiological and photosynthetic characteristics of *** to provide a theoretical reference for co.tinuous *** crop cultivation.A bioorganic fertilizer was used to treat seedlings growing in 25-year-old co.tinuous cropping *** fertilizer treatments were *** impacts of the treatments on the activity of defense enzyme and photosynthetic parameters of *** leaves were *** different co.centrations of bioorganic fertilizer reduced to varying degrees the malondialdehyde(MDA)co.tent and intercellular co. co.centration(Ci),and increased the activity of peroxidase(POD),superoxide dismutase(SOD),and asco.bate peroxidase(APX),as well as the chlorophyll co.tent,net photosynthetic rate(Pn),stomatal co.ductance(Gs)and transpiration rate(Tr)of *** *** results showed that most significant increases or decreases were achieved with 100 g/L bioorganic fertilizer(Y2).Thus,the application of bioorganic fertilizer at a rate of 100 g/L can significantly improve the activity of relevant defense enzymes and photosynthetic parameters of ***,and reduce the MDA co.tent,enhancing the stress resistance of the plants,promoting their growth and addressing,to some extent,obstacles associated with co.tinuous cultivation.
