COMPARISONS OF LEAF CHLORIDE CONTENT AND LEAF TRAITS BETWEEN TRUE MANGROVE PLANTS AND SEMI-MANGROVE PLANTS [PDF]
, 2007 依据红树植物在潮间带的分布,将其分为真红树植物和半红树植物两大类。但对一些过渡地带种类的归属问题一直存在争议。该研究选取国内大部分红树植物,比较其成熟叶片中的Cl含量、肉质化程度、比叶面积(SLA)、单位重量叶氮含量(Nmass)和单位面积叶氮含量(Narea),并对争议树种重新进行界定。结果表明:1)真红树植物叶片中Cl含量和肉质化程度远高于半红树植物;2)真红树植物具有低SLA和高Narea的特点,除水芫花(Pemphis acidula)外半红树植物具有高SLA和低Narea的特点。3 ...

Shuitu Baochi Xuebao, 2023 为优化豫北地区冬小麦在滴灌条件下的灌水技术参数,通过田间试验系统研究了不同滴头流量(2.0,4.0,6.0 L/h)和滴灌带间距(40,60,80,100,120 cm)对灌溉水在土壤中分布、冬小麦产量以及水分利用效率的影响。结果表明:就灌水均匀度而言,缩小滴灌带间距和增加滴头流量可以提高灌溉水在冬小麦根区的分布均匀度;本试验条件下滴灌带铺设超过80 cm,会影响冬小麦产量及其构成,滴灌带间距相同时,冬小麦产量随着滴头流量的增加呈递增趋势。就水分利用效率而言 ...

Study on the responses of Bougainvillea to the cold stress [PDF]
, 2015 本实验以三角梅为实验材料，研究了不同品种的三角梅对低温的适应性，旨在探究不同品种的抗寒力高低，为三角梅向北方引种提供理论依据。实验主要分为野外实验和室内试验两部分，主要结果如下： 1.确定21个三角梅品种的冬季适应等级 经过对厦门市三角梅在越冬期间的形态观察，确定三角梅21个品种的冬季低温适应能力，冬季的低温对三角梅的生长造成一定的影响。品种不同，其抗寒力不同，抗寒力强的三角梅品种的多数叶片不凋落，枝条没有明显的寒害症状，抗寒力差的三角梅品种的多数叶片凋落，植物的生长受到低温的抑制 ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Chlorination roasting has emerged as a promising pyrometallurgical strategy for the selective recovery of lithium from spent lithium‐ion batteries (LIBs). In this study, a natural roasting agent, seawater‐derived chlorides, was employed to selectively extract lithium from spent LiNi0.5Co0.2Mn0.3O2 (NCM523) cathode. MgCl2·6H2O, a main component

Shuitu Baochi Xuebao, 2018 探讨耕作方式对土壤含水量及水分利用效率的影响，对于高效利用自然降水，提高自然降水利用效率，增加作物产量具有重要的理论与实践意义。因此，采用铝盒称重法测定不同年份、季节、土壤剖面及冻融前后土壤含水量，研究不同耕作方式对土壤含水量及作物水分利用效率的影响。结果表明：在特定时期内土壤含水量随土层深度的增加而减少，特别是土层40 cm以下尤为明显，而且随季节呈波动性变化且受降雨影响较大；季节冻融作用明显降低土壤含水量，但深松较其他处理土壤含水量增幅为0.93%~2.23%；土壤贮水量随季节呈先增后降的趋势变化 ...

Critical tidal level for planting Kandelia candel seedlings in Xiamen. [PDF]
, 2006 2003年5月在厦门大屿岛白鹭自然保护区西面滩涂上试种秋茄幼苗,研究秋茄的宜林临界线.结果表明,滩涂高程为黄零0.99m处,每个潮水周期的平均淹水时间高达8h,幼苗成活率低于50%,生长缓慢,不适合用秋茄造林;在滩涂高程为黄零1.62m处,秋茄幼苗成活率达90%,生物量积累最大,光合同化作用较高,生长良好,为厦门沿海秋茄的最适生长区;而在高程为黄零1.31m处,秋茄幼苗仍能正常生长.故厦门地区秋茄造林的宜林临界线应不低于黄零1.31m(即厦零4.55m),平均每个潮水周期淹水不高于5.6h ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT The similar physicochemical properties of alkali metal elements make the co‐enrichment and precise separation of Cs+ and Rb+ in complex brine systems highly challenging. Here, an all‐inorganic strategy is proposed, which achieves efficient enrichment and precise separation of Cs+ and Rb+ in high‐salt systems by constructing Sr2+/Ba2+‐based ...
