Defoliation and fertilisation differentially moderate root trait effects on soil abiotic and biotic properties

open access: yesJournal of Ecology, Volume 111, Issue 12, Page 2733-2749, December 2023., 2023
Our results indicate that defoliation and fertilisation, two common grassland perturbations, have contrasting impacts on root traits of grassland plant species, with direct and indirect short‐term consequences for a wide range of soil abiotic and biotic properties that underpin ecosystem functioning.

Time‐limited diets and the gut microbiota in cardiometabolic disease 限时进食及肠道菌群在心脏代谢性疾病中的作用

open access: yesJournal of Diabetes, Volume 14, Issue 6, Page 377-393, June 2022., 2022
Highlights Time‐specific diet is a novel nutritional approach to prevent and treat cardiometabolic disease. Feeding‐fasting cycles shape gut microbial composition and metabolite production. These alterations may play a causative role in driving the cardiometabolic benefits of intermittent fasting.

长期不同施肥对新疆荒漠农田土壤碳含量及其剖面分布的影响

open access: yesShuitu Baochi Xuebao, 2022
以建于1990年的新疆阜康荒漠生态系统观测研究站的长期施肥定位试验为平台,分析了不施肥(CK)、单施化肥(化肥常规NPK和化肥高量N2P2K)、化肥配施秸秆(化肥配施秸秆常规NPKS和化肥配施秸秆高量NPKS2)和化肥配施猪粪(NPKM)对农田土壤有机碳和无机碳含量与剖面分布及有机碳热稳定性的影响。结果表明:(1)长期施肥处理提高了土壤有机碳含量,其中耕层(0—20 cm)土壤有机碳响应最敏感,化肥配施秸秆还田处理下有机碳积累高于其他处理。(2)长期施肥处理均降低土壤有机碳稳定性 ...

长期不同施肥制度对农田黑土有机质和氮素的影响

open access: yesShuitu Baochi Xuebao, 2005
以黑龙江省海伦黑土地区的农田长期(1985~2003年)定位试验土样为材料,对不同施肥处理土壤有机质含量、土壤全氮进行了系统研究。结果表明,长期无肥处理土壤有机质含量、全氮含量最低;长期施用氮肥、氮磷肥、有机肥处理土壤有机质含量、全氮含量居中;有机肥与化肥配合施用比无肥处理可显著提高有机质水平,增加土壤全氮含量。各处理C/N比值在9.91~13.10之间变动。

Trade‐off between soil carbon sequestration and net ecosystem economic benefits for paddy fields under long‐term application of biochar

open access: yesGCB Bioenergy, Volume 16, Issue 1, January 2024.
The use of biochar increased greenhouse gas (GHG) emissions but countered the harm caused by GHG emissions by considerable soil carbon sequestration resulting in a negative carbon footprint. Furthermore, the use of biochar lowered the proportion of CH4 and N2O, demonstrating that biochar usage has a considerable positive effect on GHG emissions ...

河套灌区节水减肥对玉米不同生育期水分和养分的影响

open access: yesShuitu Baochi Xuebao, 2021
为探究不同灌水和施肥条件对河套灌区不同生育期玉米生长的影响,以玉米"金苹628"为材料,分别研究了低水(1 800 m3/hm2)、中水(2 250 m3/hm2)、高水(2 700 m3/hm2)3个灌水水平,低肥(300 kg/hm2)、中肥(375 kg/hm2)、高肥(450 kg/hm2)3个施肥水平,并以当地一般灌水量和施肥量为对照(CK),共10个处理在苗期、拔节、抽雄、灌浆、成熟期对土壤水分、养分和玉米生长的影响。结果表明:拔节期以后,土壤平均含水率呈下降趋势;抽雄和灌浆期玉米耗水量最大,

长期施用化肥和稻草对红壤性水稻土钾素固定的影响

open access: yesShuitu Baochi Xuebao, 2011
研究了长期定位施肥试验中连续27年(1981-2007年)施用化肥和稻草对红壤水稻土钾素固定及其影响因素的影响.本试验选择了其中5个处理:CK(不施肥)、NP(施氮、磷肥)、NPK(施氮、磷、钾肥)、NP+RS(施氮、磷肥和稻草)和NPK+RS(施氮、磷、钾肥和稻草).结果表明,在加入外源钾浓度0.4~4.0 g/L的范围内,土壤固钾量均随着加入外源钾浓度的增加而增大.5个施肥处理的固钾能力存在差异,与试前土壤相比,长期不施钾(CK和NP)处理土壤的固钾能力增强,长期施钾肥或稻草(NPK、NP ...
