氮磷肥对黑土玉米农田生态系统土壤微生物量碳、氮的影响

open access: yesShuitu Baochi Xuebao, 2004
通过田间氮磷肥配施试验研究了氮磷配施对黑土玉米农田生态系统玉米不同生育时期微生物量碳、氮的影响。微生物量随玉米不同生育期的动态变化表明,氮磷肥对微生物量碳和微生物量氮的动态影响并不同步,微生物量碳和微生物量氮变化最显著的时期均是授粉期,但此时微生物量碳是最低的谷值,而微生物量氮是最高的峰值。不同氮磷配比对微生物量碳影响的回归分析表明,氮肥是影响微生物量碳的主导因素,无论是适量施用还是过量施用都是氮肥对微生物量碳的影响较大。不同氮磷配比对微生物量氮影响的回归分析表明 ...

黄土高原森林带土壤养分和微生物量及其生态化学计量变化特征

open access: yesShuitu Baochi Xuebao, 2020
选择黄土高原森林带自东向西8个地区优势植物的土壤作为研究对象,探究不同经度下土壤养分和土壤微生物生物量生态化学计量特征。结果表明:土壤碳、氮和微生物生物量碳、氮、磷含量随经度整体呈现出先减少后增加的变化趋势,土壤微生物生物量碳氮磷与土壤碳氮之间存在耦合关系,对环境因子的响应具有-致性。土壤磷含量空间分布比较稳定。土壤碳氮比为8左右,土壤有机碳与全氮的空间分布具有-致性。土壤微生物生物量碳氮比为9左右,微生物生物量氮磷比为5左右,反映了土壤微生物生物量碳氮、氮磷的比值较稳定 ...

Movement and Space Use Patterns of the Beale's Eyed Turtle (Sacalia bealei) Suggest Sensitivity to Environmental Changes and Poaching 比氏眼斑龟 (Sacalia bealei) 的活动与空间利用模式揭示其对环境变化及盗猎的敏感性

open access: yesWildlife Letters, EarlyView.
Using radiotelemetry, we found that the movement and home range of the endangered Sacalia bealei varied significantly across reproductive classes and seasons, with males exhibiting greater movement than females during wet and mating seasons. The species exhibits strong aquatic dependence, favoring deep pools interspaced among riffle‐pool sequences ...

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

open access: yesFunctional 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 ...

阿特拉津除草剂对土壤微生物生态特征的影响

open access: yesShuitu Baochi Xuebao, 2005
采用实验室培养试验研究了阿特拉津除草剂对土壤微生物生态特征的影响。结果表明:阿特拉津除草剂10mg/kg浓度处理释放的CO2与对照无明显差异,根据危害系数法的分级方法,其属于无实际危害级农药;阿特拉津除草剂10mg/kg浓度处理在初始阶段,明显降低土壤微生物生物量碳和微生物生物量氮,随培养时间推移土壤微生物生物量碳和生物量氮有所恢复,随后又有所下降,30d后土壤微生物生物量变化趋于平缓;阿特拉津除草剂对土壤微生物多样性产生一定影响.其影响随培养时间而异 ...

Land use overrides climatic controls on soil organic nitrogen transformations: Contrasting responsiveness between forest and cropland ecosystems

open access: yesFunctional 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.

施肥对金沙江干热河谷退化草地土壤微生物的影响

open access: yesShuitu Baochi Xuebao, 2005
在金沙江干热河谷区的退化草地上进行了2年的氮磷施肥试验,试验结束后分析了土壤特性及土壤微生物数量和生物量的变化。结果表明,在施氮量为5 ,15g/ (m2 ·a)时,土壤微生物的数量和生物量均没有明显变化,而当施氮量增加到2 5g/ (m2 ·a)时,土壤微生物的数量和生物量比对照明显增加。施磷没有引起土壤微生物数量和生物量的明显增加。施氮和施磷均没有引起土壤细菌、真菌和放线菌组成的变化。这表明氮虽然影响土壤微生物的数量,但对土壤微生物的组成没有影响。施氮导致土壤硝态氮增加,但对氨态氮影响不大 ...
