Water-saving irrigation is becoming more important in the upper Yellow River basin (YRB) due to reduced water allocation and growing scarcity. However, drip as an efficient method, has not gained much acceptance one might expect. In this study, integrated approaches involving field experiments, agro-ecosystem modeling, financial analysis were proposed evaluate multiple benefits of two methods. Field experiments on maize irrigated with border under plastic mulching (i.e., BI-M DI-M) conducted...

Abstract Haihe plain is an important food production area in China, facing increasing water shortage. The used for agriculture accounts about 70% of total resources. Thus, it critical to optimize the irrigation scheduling saving and crop productivity (CWP). This study first simulated yield CWP winter wheat summer maize historical scenario during 1961–2005 using previously well‐established Soil Water Assessment Tool model. Then, scenarios under (scenario 1) sufficient 2) were, respectively,...

Abstract Quantitative assessment of surface water resources (SWRs) and evapotranspiration (ET) is essential significant for reasonably planning managing in the Haihe River basin which facing severe shortage. In this study, a distributed hydrological model was constructed using Soil Water Assessment Tool, well considering reservoirs agricultural management practices reasonable simulation. The crop parameters were independently calibrated with observed data at six experimental stations. Then,...

Updated and accurate land cover maps are essential crucial for sustainable crop production efficient management. However, mapping is still a challenge agricultural regions with complicated landscapes. This study proposed novel spectral-phenological based classification (SPLC) method to identify the fragmented landscapes, less requirement of ground truth data. The SPLC integrated pixel-based support vector machine (SVM) algorithm cropland various non-cropland classification, phenology-based...

Abstract Groundwater recharge and capillary rise are key factors in water balance management studies carried out irrigated areas with shallow groundwater tables. In this study, the mathematical model SWAP‐EPIC was applied to analyse processes of Hetao Irrigation District upper Yellow River basin. The calibrated validated using non‐weighing lysimeter data collected 2007 2008, respectively. Simulations soil content, depth, leaf area index yield fitted well observations. further used response...

Drought and floods affect the growth yield of maize, affecting food security. Therefore, it is crucial to assess maize’s drought waterlogging status in various stages. We used phenological daily meteorological data spatial analysis identify conditions spring maize Northeast China eight calculated crop water surplus/deficit index national standard for waterlogging. The results indicate a significant decreasing trend effective precipitation China. requirements changed during growing period....

Antimicrobial resistance (AMR) is commonly associated with the inappropriate use of antibiotics during meat-rabbit production, posing unpredictable risks to rabbit welfare and public health. However, there limited research on epidemiological dynamics antibiotic among bacteria indicators derived from local healthy meat-rabbits. To bridge knowledge gap between AMR distribution, a total 75 Escherichia coli ( E. ) 210 Enterococcus spp. strains were successfully recovered fecal samples The...

Abstract Current hydrological models still face difficulties in accurately simulating vadose zone (VZ) processes arid watersheds with shallow groundwater environments. Therefore, this article introduces a new mechanistic VZ module coupled an improved groundwater‐balance (GWB) to enhance the capabilities of well‐known Soil Water Assessment Tools (SWAT) model. The main improvements and features modified SWAT model (M‐SWAT) include: numerical simulate soil water‐salt transport under variably...

Identifying important parameters in crop models is critical for model application. This study conducted a sensitivity analysis of 23 selected the advanced rice ORYZA-N using Extended FAST method. The was applied three types (single-season cold regions and double-season (early late rice) subtropical regions) two irrigation regimes (traditional flood (TFI) shallow–wet (SWI)). analyzed parameter six growth outputs at four developmental stages yields. Furthermore, we compared variation on...

The Rolling Hilly Region of Northeast China (RHRNEC) is a critical grain production area in China, and soil erosion major problem this region. To determine spatial temporal changes rainfall erosivity (RE) the RHRNEC generate information useful for water conservation, agricultural management, ecological protection efforts, RE index consisting nine indices based on normal extreme precipitation was established. (NREI) comprised annual (ARE), wet season (WRE), dry (DRE), typical wet-month...

Abstract Many agro‐environmental studies focusing on the efficient management of soils and water resources make use soil simulation models. Reliable hydraulic properties are critical for ensuring accuracy model simulations. However, parameters in northern China generally derived using external pedotransfer functions (PTFs) that do not take into account specificities local edaphoclimatic conditions due to lack a better alternative. Therefore, main objective this paper was develop PTFs...
