Plant functional trait dissimilarity drives plant mixture effects on fine root biomass and trait variations. [PDF]

open access: yesNew Phytol
Summary Fine roots are critical for soil resource uptake, yet how declining plant diversity alters fine root biomass (RB) and traits remains unclear. We tested how plant functional trait dissimilarity in shade tolerance, drought tolerance, growth rate, and nitrogen‐fixation ability drives variation in root attributes.

Variation in mycorrhizal communities and the level of mycoheterotrophy in grassland and Forest populations of Neottia ovata (Orchidaceae)

open access: yesFunctional Ecology, Volume 37, Issue 7, Page 1948-1961, July 2023., 2023
Read the free Plain Language Summary for this article on the Journal blog. Abstract Orchid mycorrhiza forms unique symbiotic associations between members of the Orchidaceae and multiple ecological guilds of fungi. Because orchids associate with a wide variety of fungi with different ecological functions, they represent an ideal study system to address ...

Factors that shape large‐scale gradients in clonality

open access: yesJournal of Biogeography, Volume 50, Issue 5, Page 827-837, May 2023., 2023
Abstract Aim Many plant species reproduce clonally. However, ecologists still have much to learn about the factors that shape large‐scale patterns in plant clonal growth and reproduction, especially in the southern hemisphere. We addressed this knowledge gap by quantifying relationships between reproductive mode and a suite of plant characteristics and

氮肥基追比对小麦产量、土壤水氮分布及利用的影响

open access: yesShuitu Baochi Xuebao, 2020
为解决区域土壤质地类型针对性氮肥施用问题,在轻壤土和黏壤土上分别设置不施氮肥,氮肥基追比3:7,4:6,5:5,6:4和7:3处理,研究小麦产量、水氮利用效率以及土壤含水量、贮水量、NH4+-N、NO3--N动态变化规律。结果表明:轻壤质土壤氮肥基追比4:6的处理小麦产量、水分利用效率、氮肥生产效率最高分别为8 265.3 kg/hm2,27.6 kg/(hm2·mm),34.4 kg/kg。黏壤质土壤氮肥基追比5:5的处理小麦产量、水分利用效率、氮肥生产效率最高分别为8 363.2 kg/hm2,28.

苗期干旱胁迫下施氮对玉米氮素吸收和土壤生物化学性质的影响

open access: yesShuitu Baochi Xuebao, 2021
研究苗期干旱胁迫下施氮对东北春玉米氮素吸收利用和土壤生物化学性质的影响,为区域玉米养分管理与逆境调控提供依据。研究设置水、氮二因素盆栽试验,土壤水分包括3个水平:田间持水量的30%(W0),50%(W1)和70%(W2);施氮量包括2个水平:不施氮(N0)和施氮0.24 g/kg(N1),测定不同水氮条件下玉米苗期的植株干重和氮素吸收、根际和非根际土壤的化学性质、微生物量碳、氮(MBC、MBN)及土壤酶活性。结果表明:干旱胁迫显著降低玉米苗期植株干重和氮素吸收量,其中W0条件降幅最大(分别为51.1 ...

Field studies in Soil Nitrogen Mineralization in an Agriculture Catchment, South Fujian Province [PDF]

open access: yes, 2007
人类活动对地球系统的影响迅速扩大,大量氮肥的输入使得生态系统氮超载,土壤氮矿化作为土壤氮转化的一个内部过程,在氮循环过程中起着非常重要的作用。农民在施肥期间往往忽略了土壤氮矿化这部分氮输入,盲目的追加化肥,导致氮元素的大量流失,引发一系列的生态环境问题。因此系统分析农田不同土地利用方式下土壤氮矿化负荷,并在此基础上对五川流域氮的收支进行试验研究,对指导农民具体施肥,提高氮的利用率,减少氮流失,降低环境中过量氮存在的风险具有重要的理论和实践意义。 本文以南靖县五川流域为例,以环境科学、农业生态学、农艺学 ...
