Shuitu Baochi Xuebao, 2005 通过对保水剂和旱地龙这两种抗旱节水剂在苹果生长上的试验研究,分析了抗旱节水剂集成应用对土壤含水率、苹果产量、苹果品质(主要指可溶性固形物)的影响。结果表明,施用抗旱节水剂可增加土壤含水率和果实品质,增产达13365 06～19036 58kg/hm2,增加纯经济效益20570～34750元/hm2;水分利用效率提高,每1hm2节水892m3,同时对抗旱节水剂应用条件下的果树灌溉制度进行了研究,提出了不同降雨年型的灌溉制度。

Shuitu Baochi Xuebao, 2023 为探究河套灌区沈乌灌域在深度节水改造前后地下水环境的演变规律,针对地下水埋深、矿化度以及二者关系,通过区域布井、定位长期监测方式,采用经典地统计学理论,分析地下水埋深和矿化度的时空变化规律。结果表明:(1)深度节水改造后,沈乌灌域地下水埋深呈增大趋势,平均地下水埋深由节水改造前1.83 m增大到节水改造后3.36 m,增长率为83.9%。灌域中心和南部埋深偏大,局部产生漏斗,最大埋深至9.37 m,灌域北部埋深变化为0.6 m以下。(2)节水改造工程实施,使地下水矿化度显著增高,由节水改造前的1 296

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Shuitu Baochi Xuebao, 2000 利用汇集雨水对春小麦进行补灌方式、补灌时期及补灌量的试验表明，不论贫水年和丰水年，有限滴灌均能明显使作物节水增产。膜下滴灌方式的保墒节水效应和提高水分利用效率作用明显；春小麦的拔节一孕穗期是实施补灌的关键时期；春小麦全生育期滴灌补灌定额900m^3/hm^2，重点应加强促苗水、拔节水、孕穗水和灌浆水。

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Soil organic nitrogen (SON) transformation is critical for global nutrient cycling and ecosystem productivity, yet how its responsiveness to climate change differs across diverse land use types remains poorly resolved.

Habitat and spatial trends of U.K. wintering waterbird populations over 50 years
Conservation Biology, EarlyView.Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...

The underappreciated roles of fog and dew on vegetation and biocrusts
New Phytologist, Volume 251, Issue 1, Page 46-63, July 2026.Summary Fog and dew represent minor components of ecosystem water budgets in most ecosystems. However, fog and dew can play an essential role in ecosystem dynamics and are particularly important for water‐limited systems. In addition to serving as direct water inputs, fog and dew can influence microclimate and water redistribution, thereby promoting ...
