Soil compaction easily causes root hypoxia stress, resulting in poor growth and the absorption of soil water nutrients. We hypothesized that aerated irrigation (AI) could enhance nutrient uptake utilization, thus unlocking high yield potential by increasing aeration morphology indicators compared with non-aeration treatment. A greenhouse experiment was conducted to investigate effect on cucumbers. The dissolved oxygen (DO) at 10 mg L−1 (A1), 20 (A2), treatment (A0) were applied via a...

Diarrhea is a word-widely severe disease coupled with gastrointestinal dysfunction, especially in cattle causing huge economic losses. However, the effects of currently implemented measures are still not enough to prevent diarrhea. Previously we found that dropped short-chain fatty acids diarrhea yaks, and butyrate commonly known be related epithelial barrier function intestinal inflammation. it unknown whether sodium acetate/sodium could alleviate animals. The present study carried out...

In order to study the soil nitrogen (N) distribution pattern in root zone of chili peppers under aerated drip irrigation (ADI) conditions and analyze relationship between N crop growth, two methods (conventional ADI) three levels (0, 140, 210 kg hm−2) were set up this experiment. Soil samples collected by auger method at end different reproductive periods, uniformity coefficient spatial was calculated Christiansen’s coefficient. The growth status soil-related indices pepper determined each...

Synchronous fluorescence spectroscopy (SFS) combined with principal component analysis (PCA) and two-dimensional (2D) correlation was applied to investigate removal efficiencies variations of dissolved organic matter (DOM) fractions in the wastewater treatment plant (WWTP) an A2O craft. A decreasing order total tyrosine-like (89.58%) > humic-like (HLF) (39.83%) tryptophan-like (36.89%) microbial (12.47%) fulvic-like (6.37%). The tyrosine-like, HLF components were deeply decomposed by...

Root hypoxia stress and soil nutrient turnover have been related to reduced crop productivity. Aerated drip irrigation (ADI) can effectively enhance productivity yield. However, the response of bacterial community different water dissolved oxygen (DO) concentrations remains elusive due extreme sensitivity microorganisms environmental variations. We investigated effects aerated with DO on properties agronomic performance cucumber, as well contribution community. performed experiments cucumber...

In order to provide a theoretical basis for the rational application of nitrogen fertilizer tomatoes under aerated drip irrigation, model critical dilution curve was established in this study, and feasibility nutrition index (NNI) real-time diagnosis evaluation nutrient status explored. The tomato variety “FENOUYA” used as test crop, irrigation adopted by setting three levels aeration rates, namely, A1 (dissolved oxygen concentration water is 5 mg L−1), A2 15 A3 40 N1 (120 kg ha−1), N2 (180...

China's industry accounts for 46.8% of the national Gross Domestic Product (GDP) and plays an important strategic role in its economic growth. On other hand, industrial wastewater is also major source water pollution. In order to examine relationship between underlying driving forces various environmental indicators, values two critical pollutant discharge parameters (Chemical Oxygen Demand (COD) ammonia nitrogen (NH(4)-N)), 2001 2009, were decomposed into three factors: i.e., production...

In order to investigate the effects of water-fertilizer-air-coupling drip irrigation on soil health status, including aeration (SA), enzyme activity (EA) and microbial biomass (MB), its response relationship, this glasshouse experiment was conducted using tomato as test crop, we designed two fertilization gradients 135 180 kg N·ha−1, levels 0.6-fold 1.0-fold crop-pan coefficient, treatments 5 15 mg·L−1 for three-factor two-level completely randomized block experiment. The dissolved-oxygen...

In order to unravel the effect of aerated irrigation on soil dissolved organic matter (DOM) fluorescence characteristics, and humification degree, a randomized block experiment was conducted with three factors two-level design, i.e., two rates (0.6 1.0 times crop evaporation pan coefficient, W1 W2), nitrogen application (225 300 kg hm−2, N1 N2), aeration (15% 0% in control treatment, A1 A0). Fluorescence regional integration (FRI) correlation analysis methods were used investigate evolution...

The current study was undertaken to investigate the dynamic characteristics of tomato crop, such as its plant height and leaf area index (LAI), based on effective cumulative temperature. This assessed under aerated drip irrigation (ADI) conditions application a specific nitrogen (N) dose, their relationship with yield crop formulated. conducted in greenhouse located Zhengzhou, Henan province, China. assessment were two methods, ADI conventional (CK), three N rates, i.e., 0, 140, 210 kg ha−1....

China is one of the regions with most frequent drought disasters and serious social economic losses. Agricultural natural disaster. Due to climate change, regional agricultural risk assessment has always been focus academic circle. This study takes Zunyi City as an example, which typical city karst landform development. The monthly precipitation data set ground meteorological observation stations in from 1956 2020 was selected, characteristic variables were extracted by coupled use anomaly...

A vegetable water production function has been one of the most significant parameters to improve use efficiency and economic benefit agricultural in greenhouse. Meanwhile, aerated irrigation unlocks high yield potential for greenhouse crop production. Thus, water, fertilizer air coupled is proposed optimization scheme during tomato growth period. Two seasons experiments were conducted under subsurface drip (ASDI). There three nitrogen application rates (N1, 120 kg ha−1; N2, 180 N3, 240 ha−1)...

Abstract Aerating water using microbubbles in irrigation for drip and subsurface systems has been reported to produce positive effects on plant growth yield. However, maintaining the uniformity of bubble distribution lines across long‐row configuration is a challenge.
