Nitrous oxide (N2O) is a potent greenhouse gas (GHG) with agricultural soils representing its largest anthropogenic source. However, the mechanisms involved in N2O emission and factors affecting fluxes response to various nitrogenous fertilizer applications remain uncertain. We conducted four-year (2012–2015) field experiment assess how fertilization scheme impacts emissions from rice-wheat cropping system eastern China. The treatments included Control (CK), Conventional (CF), CF...
Recently, replacing chemical fertilizers with straw returning and new has received considerable attention in the agricultural sector, as it is believed to increase rice yield improve soil properties. However, less known about growth properties paddy fields addition of different fertilizers. Thus, this paper, we investigated effects fertilizer treatments, including no fertilization (CK), optimized based on medium recommended amount (OF), 4.50 Mg ha−1 (SF), 0.59 slow-release (SRF), 0.60...
The modification of clay minerals by exopolysaccharides (EPS) may significantly increase their adsorption capacity for heavy metals. This study focused on the EPS (produced Rhizobium tropici)-modified montmorillonite (MMT) and kaolinite (KLT) Cs Sr influence external factors (pH, sulfate, phosphate). characterization composites was carried out using X-ray diffraction (XRD), Fourier transform infrared (FTIR), atomic force microscopy (AFM), scanning electron microscopy/energy-dispersive...
The public space environment of historical and cultural blocks is inseparable from human activities, which affects tourists’ behavior perception activities. Through the evaluation environmental perception, relationship between spatial characteristics fully considered, plays an important role in protection development blocks. This paper takes block Sanhe Ancient Town Hefei as research area, focusing on block. analysis semantic differential method eye movement legal quantitative analysis,...
Electrokinetic-enhanced phytoremediation is an effective technology to decontaminate heavy metal contaminated soil. In this study, we examined the effects of electrokinetic treatments on plant uptake and bioaccumulation U from soils with various sources. Redistribution uranium in as affected by planting was investigated. The soil spiked 100 mg kg–1 UO2, UO3, UO2(NO3)2. After sunflower Indian mustard grew for 60 days, 1 voltage direct-current applied across 9 days. results indicated that both...
The prediction of soil organic matter is important for measuring the soil’s environmental quality and degree degradation. In this study, we combined China’s GF-6 remote sensing data with content obtained from sampling points in study area to predict content. To these data, applied random forest (RF), light gradient boosting machine (LightGBM), tree (GBDT), extreme (XGBoost) learning models. We used coefficient determination (R2), root mean square error (RMSE), absolute (MAE) evaluate model....
Low-molecular-weight organic acids (LMWOAs) are essential components of rice roots exudates and an important source soil carbon. The chemical-microbial pathway by which LMWOA affects arsenic (As) cycling in the rhizosphere paddy soils is still unclear. In this study, three typical LMWOAs (acetic acid (AA), oxalic (OA), citric (CA)) root were added to As-contaminated at a concentration 10 mM, mimicking environment. results showed that addition AA OA inhibited mobilization As soil. After 14...
The accumulation of heavy metals in rice is bound to affect human health and safety. In order ensure food security, this study explores the effect leaf surface regulation zinc (Zn) fertilizer on safety cadmium (Cd)-plumbum (Pb) polluted farmland. Through field experiments, control treatment was set up, effects yield, Cd Pb concentration different parts zinc, nitrogen, phosphorus potassium brown were studied growing period rice. results showed as follows: (1) Spraying twice or more growth...
Cultivated land quality is an essential agricultural resource and production element. To increase cultivated in a targeted way, it crucial to understand the features of regional elements that constrain its quality. In order diagnose restriction factors affecting improvement grades conduct quantitative analysis factors, index model was used this study analyze distribution characteristics East Anhui, China. The results show there are six main area, which effective soil layer thickness, organic...
To investigate the effects of biogas slurry substitution for fertilizer on rice yield, utilization efficiency, and soil fertility, a field experiment was conducted rice-wheat rotation in Chaohu Lake Basin two consecutive years, with following six treatments: no fertilization (CK), conventional (CF), optimized (OF), replacing 15% (15% OFB), 30% (30% 50% (50% OFB). The results showed that, compared CF treatment, OF treatment 2022 2023 significantly increased (
To treat heavy-loaded wastewater from small-scale livestock farms, a combined constructed wetland system was designed, which includes series of hybrid wetlands made up surface flow (SF) and subsurface (SSF) compartments, as well two anaerobic units, also in series, its pretreatment. The combination multitype multistage treatment units the division area into compartments horizontal baffled layout prolongs hydraulic retention time (HRT), reduces clogging short-circulating, keeps specific...
The evaluation of resources and environment carrying capacity (RECC) is the basis strategic policy for development utilization regional resources, economic development, environmental protection. magnitude result balance multiple aspects including economy, society. In order to reflect this multi-dimensional vector relationship, a multi-level multi-targeted index system needs be constructed. paper, adopting analytic hierarchy process PM2.5 (Particulate matter with diameter less than or equal...
Proper utilization of lightly contaminated farmlands is popular for developing countries such as China where there are high demands food production to meet the needs population in limited available arable lands. Oilseed rape (Brassica napus L.) an important oil crop well a potential candidate soil Cd remediation. Dietary ingestion main route human exposure cadmium (Cd). Therefore, understanding characteristics transfer soil-oilseed system and its health risk assessment crucial alleviation...
Selection of rice varieties and application amendments are effective measures to ensure food safety. Here we report that in the non-Cd area, grain quality all met Chinese National Grain Safety Standards (CNGSS). In high-Cd showed significant different bioaccumulation Cd with lower yields than those area average decrease 31.1%. There was a negative correlation between content yields. A total 19 were selected as low accumulating their CNGSS low-Cd area. Six them The significantly reduced...
