The North China Plain (NCP) has progressively implemented drip irrigation for winter wheat (Triticum aestivum L.) production because of its substantial water saving and improved nitrogen (N) use efficiency. Nevertheless, the ideal water-N utilization regime drip-irrigated remains ambiguous. Two years field experiments were carried out to assess influences different N fertigation regimes on grain yield (GY), evapotranspiration (ETc), productivity, optimization procedure (TOPSIS). two quotas...
High-low seedbed cultivation (HLSC) is a key technique now used by smallholder and large farmers to increase the land utilization rate of wheat production in North China Plain (NCP). However, little information available on its superiority crop productivity, resource efficiency, net return comparison with flat (FC). A field experiment was conducted NCP 2020–2021 2021–2022 seasons determine whether HLSC would evapotranspiration (ET), intercepted photosynthetically active radiation (IPAR),...
Sound irrigation and nitrogen management strategies are necessary to achieve sustainable yield water use efficiency of winter wheat in the North China Plain (NCP). The coupled effects scheduling application mode (NAM) on growth, under drip were evaluated with a two-year field experiment, which consisted three levels (ISLs) (irrigating when soil consumption (SWC) reached 20, 35 50 mm, referred as I20, I35 I50, respectively) modes (NAMs) (ratio basal topdressing 50:50, 25:75 0:100, N50:50,...
Chemical fertilizer overuse is a major environmental threat, critically polluting soil and water resources. An optimization of nitrogen (N) application in winter wheat (Triticum aestivum L.) association with various irrigation scheduling potential approach this regard. A 2-year field experiment was carried out to assess the growth, yield photosynthetic capacity drip-irrigated subjected split applications urea (240 kg ha-1, 46% N). The eight treatments were, two six N modes which, one...
Stable hydrogen and oxygen isotopes provide a powerful technique for quantifying the proportion of root water uptake (RWU) from different potential sources. Although many models coupled with stable have been developed to estimate plant source apportionment, inter-comparisons methods are still limited, especially their performance under soil content (SWC) conditions. In this study, three Bayesian tracer mixing models, which included MixSIAR, MixSIR SIAR, were tested evaluate performances in...
The aim of this study was to optimize water-saving and high-efficiency irrigation nitrogen application scheduling for greenhouse tomato cultivation in North China. Using experimental data on water inputs, the DSSAT-GLUE parameter adjustment tool employed calibrate genetic parameters DSSAT–CROPGRO–Tomato model. Simulations were conducted assess growth, use, yield under varying conditions. After calibration, model showed average relative errors 3.19% phenological stages, 3.33% plant height,...
In order to explore the applicability of peanut growth simulation model CSM-CROPGRO-Peanut under conditions mulched drip irrigation in Xinjiang, and determine optimal scenario for parameter estimation validation, field experiments were conducted 2022 2023 on water nitrogen regulation peanut. Based requirements during stages growth, three levels (low, medium, high) two application (100% N 50% N) set, resulting six treatments. An additional control treatment (CK) with a medium level no was...
摘要春季低温（LT）已成为制约小麦生长发育的主要非生物胁迫之一。为研究小麦籽粒发育对孕穗期低温胁迫的响应机制，进行了多种分析，包括孕穗期低温处理后小麦籽粒形态观察、淀粉合成酶活性测定以及直链淀粉和支链淀粉含量测定。此外，利用串联质谱标签技术（TMT）进行了蛋白质组学分析。结果表明，低温胁迫后小麦籽粒的饱满度下降。此外，蔗糖合酶（SuS, EC 2.4.1.13）和腺苷二磷酸葡萄糖焦磷酸化酶（AGPase,...
Drought and salinity stress reduce root hydraulic conductivity of plant seedlings, melatonin application positively mitigates stress-induced damage. However, the underlying effect priming on seedlings under drought–salinity combined remains greatly unclear. In current report, we investigated influence seeds three wheat lines’ 12 h with 100 μM (Lpr) relevant physiological indicators PEG, NaCl, PEG + NaCl stress. A previous study found that remarkably reduced Lpr varieties, its value could not...
We aimed to assess the effect of water deprivation on root traits and establish if wheat cultivars Spica Maringa would be useful as parental germplasm for a genetic analysis traits. Plants were grown in two markedly different soils under well-watered water-limited treatments controlled environment growth cabinets. The drought treatment was imposed gradual depletion over 28 days seedlings grew from defined starting moisture content. analyzed included length, nodal number, thickness angle....
Reducing crop luxury transpiration is an important step in improving water productivity; shortage regions are potential hotspots for studying physiological conservation. This study investigated the amount of winter wheat and its responses to different irrigation treatments North China Plain. The results showed that existed increased with growth after rainfall. In each sampling day, under full was significantly higher than deficit irrigation. average 258.87 g/m2 irrigation, 125.18 during...
Plant physiological responses to various stresses are characterized by interaction and coupling, while the intrinsic mechanism remains unclear. The effects of intraspecific competition on plant growth, stomatal opening, hormone concentrations were investigated with three tomato genotypes (WT-wild type, Ailsa Craig; FL-a abscisic acid (ABA) deficient mutant, flacca; NR-a partially ethylene-insensitive genotype) under two water regimes (full irrigation, irrigation amount = daily transpiration;...
In the North China Plain, drip irrigation is gradually used in winter wheat production, and improper management of water fertilizer aggravates risk crop instability groundwater pollution. A lysimeter experiment with three levels fertilization timing (T1 = beginning; T2 middle; T3 end cycle) two rates (W1 30 mm W2 20 mm) was carried out to investigate effects rate on soil NO3−-N distribution, development, yield, water–nitrogen usage efficiency wheat. The results indicated that, under...
During four consecutive growing seasons (2014–2018), field experiments were conducted in the North China to determine winter wheat production function. The carried out using subjected N levels (N120, N180, N240, and N300) three irrigation (If, I0.8f, I0.6f). main aims characterize productivity, drought response factor Ky, grain yield functions relation water supply under different fertilizer levels. amount of (rain + irrigation) 326–434, 333–441, 384–492, 332–440 mm 2014–2015, 2015–2016,...
