耕作方式和氮肥用量对旱地小麦产量、水分利用效率和种植效益的影响
Shuitu Baochi Xuebao, 2021 为探索旱地小麦增产增效增收协同的耕作方式及其配套施氮技术。2016—2017（欠水年）和2017—2018（丰水年）年度，在豫西典型旱区洛宁县设置夏闲期深松（ST，麦收后2周左右隔年进行）和翻耕（PT，传统的7月或底8月初连年进行）2种耕作方式为主区，设置4个氮肥用量为副区（播前基施纯氮0（N0），120（N120），180（N180），240（N240） kg/hm2）的田间定位试验，分析了土壤水分以及小麦产量、水分利用效率和种植效益。结果表明：与翻耕相比，深松提高了休闲效率，播前、开花期和成熟期0 ...

Shuitu Baochi Xuebao, 2020 以青海省德令哈枸杞产区不同沟垄措施下的枸杞地为研究对象，以无覆盖平作枸杞地为对照（CK），在分析该地区降雨特征的基础上，研究了沟垄覆膜措施下不同沟垄比（30：32 cm，24：32 cm，18：32 cm，12：32 cm）对枸杞土壤含水率、产量及水分利用效率的影响。结果表明：（1）在年降水量不足300 mm的试验区，沟垄覆膜不同沟垄比种植相比于无覆盖平作种植土壤含水率、产量及水分利用效率显著升高，增产节水效果最优的GLBc （沟垄比18：32 cm）处理相比CK产量提高60.14%，耗水量降低7.47%

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Aqueous zinc‐ion batteries are plagued by anode challenges such as dendrite growth and corrosion, which stem from intrinsic surface heterogeneity. Although constructing a homogeneous interfacial layer is a promising strategy, conventional electrolyte additives often suffer from incomplete or unstable coverage.

Jellyfish blooms restructure plankton dynamics and trophic linkages in coastal waters
Functional Ecology, Volume 40, Issue 5, Page 1443-1460, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Jellyfish blooms are increasing globally in frequency and intensity, introducing complex ecological interactions, yet the mechanisms by which they alter ecosystem structure remain poorly characterized due to a lack of sustained field observations.

Shuitu Baochi Xuebao, 2004 采用312-D最优饱和设计,在辽西半干旱区开展了连续4年的春小麦田间水肥耦合试验,研究春小麦水分利用效率.结果表明水肥单因子对水分利用效率有显著影响,影响顺序为水＞磷＞氮.其中,氮、磷施用量对水分利用效率的提高是正效应,而灌水量对水分利用效率是负效应.水肥多因子对水分利用效率有交互效应,氮与磷之间、氮与水之间的交互效应极显著,对水分利用效率表现为正效应.磷与水之间表现为负效应,但不显著.水分利用效率超过10 kg/(hm2·mm)的水肥优化管理方案为,施氮量102.6～239.3 kg/hm2 ...
