, 2014 以山东省沂蒙山区夏玉米田为研究对象,设化学除草剂除草(CK)、不除草(W0)、苗期人工锄草1次(W1)、苗期+开花期人工锄草两次(W2)4种处理方式,研究除草次数对农田杂草生物多样性和对夏玉米产量的影响。结果表明,玉米田中9种杂草的多样性指数以W0处理最高,W1处理次之;花后40 dW1、W2处理玉米地上部生物量与CK差异不显著(P0.05)W0处理与CK差异显著(P0.05)产量也表现出相同规律。研究表明,当地苗期适时进行1次除草,不仅能维持杂草多样性,而且可避免作物产量损失;与人工锄草两次相比 ...

Overreliance on Orthographic Similarity in L2‐Japanese Conceptual Processing by L1‐Chinese Learners
International Journal of Applied Linguistics, Volume 36, Issue 2, Page 1807-1820, May 2026.ABSTRACT Orthographic and phonological similarities between first (L1) and second (L2) languages can facilitate L2 processing. Particularly, L1‐Chinese learners of L2‐Japanese can benefit from the shared morphosyllabic Chinese characters (Japanese kanji/Chinese hanzi) because of their similar orthographies.

Veterinary Dermatology, Volume 37, Issue 2, Page 247-256, April 2026.ABSTRACT Background Identification of offending foods in dogs with adverse food reactions is usually based on “deterioration” during open food challenges. Objectives To examine the placebo effect during double‐blinded, placebo‐controlled food challenges using a predefined set of criteria for relapse.

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Regulating negative parameters of metacomposites is mainly limited by their unclear mechanisms, which affects their practical applications in new sensing, communication, electromagnetic (EM) protection and other fields. This work proposes a dual‐functional competitive design strategy based on the waste corncob‐derived carbon/polyaniline ...

Porous Mn2O3@C Cathode With High Activity and Long Lifespan for Aqueous Zinc Ion Batteries
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Manganese‐based oxides are widely employed as cathode materials for aqueous zinc ion batteries (AZIBs) due to their low toxicity and high theoretical specific capacity. However, their inherent poor electrical conductivity, coupled with the dissolution of manganese into the electrolyte, often leads to structural degradation of the cathode.

Effects of crop species on soil functions and soil multifunctionality are species‐specific
Functional Ecology, Volume 39, Issue 9, Page 2354-2369, September 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Soil multifunctionality is essential for sustainable agriculture, as soils not only need to support crop growth but also maintain soil biodiversity and sustain other critical ecosystem functions.

Gongye shui chuli, 2020 研究了NaOH、HNO3改性玉米秸秆对水中Cu2+的吸附性能及吸附特性。研究表明，改性后的秸秆表面光滑，结晶指数高，对Cu2+的吸附容量增大。相比未改性玉米秸秆和酸改性玉米秸秆，碱改性玉米秸秆对Cu2+的吸附效果最好。碱改性玉米秸秆对Cu2+的吸附能较好地符合Freundlich方程和伪二级动力学模型。初步推断吸附机理是秸秆表面官能团与Cu2+络合形成复合体的化学吸附过程。
