Shuitu Baochi Xuebao, 2006 通过盆栽模拟干旱试验，测定了干旱胁迫下玉米根系生长情况和根际土壤中速效N、P、K的含量。结果表明，干旱胁迫抑制了玉米拔节期和抽雄-开花期玉米根系的生长，减弱了玉米根系的吸收能力。干旱胁追下玉米根际NH4^＋-N、NO3^--N、速效P和速效K均发生根际富集现象。其中有效N和速效K含量高于正常供水．而速效P却呈现低于正常供水的趋势。干旱胁追抑制玉米根系生长、减弱根系吸收能力是玉米减产的重要原因。

Shuitu Baochi Xuebao, 2005 三峡库区春玉米盆栽水肥耦合试验研究结果表明，水分胁迫导致玉米株高和叶面积指数降低，以拔节期受到影响最大；玉米产量与生物量呈显著正相关关系，产量与根重无显著正相关关系；水氮耦合效应显著，适宜水分和中氮处理下玉米的产量最高，玉米生长发育对氮肥的吸收存在一定的阈值，过多施用氮肥会加剧土壤干旱和作物干旱，水和钾耦合效应对玉米产量影响不显著；水分是影响玉米产量的主导因素，其次是氮效应和钾效应。

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.

Shuitu Baochi Xuebao, 2018 通过田间小区试验种植玉米（玉米单作、玉米//大豆、玉米//马铃薯），测定3个生育期（拔节期、大喇叭口期、抽雄期）玉米根系分泌总糖含量、总有机酸含量和土壤团聚体状况，分析间作对玉米根系分泌物及团聚体稳定性的影响。结果表明：玉米根系分泌总糖含量和总有机酸含量随生育期的推移而增加，间作显著提高玉米根系分泌总糖含量和总有机酸含量，玉米//马铃薯>玉米//大豆。在抽雄期，玉米//大豆、玉米//马铃薯相比玉米单作>0.25 mm水稳性团聚体含量（R0.25）分别显著提高6.19%，8.17%；平均质量直径（MWD ...
