Plastic mulching with drip irrigation is a new water-saving rice cultivation technology, but little known on its productivity and capacity. This study aimed to assess the production potential, performance, water use efficiency (WUE) of under plastic irrigation. Field experiments were conducted over 2 years two cultivars different systems: conventional flooding (CF), non-flooded incorporating furrow (FIM), non-mulching (FIN), (DI). Compared CF treatment, grain yields reduced by 31.76–52.19%...
Cation exchange capacity （CEC） reflects the ability of soil to sequester exchangeable cations and is an important indicator fertility environmental quality agricultural soils. The indoor titration method for determining cation expensive cumbersome. To this end, 565 samples from 0-20 cm plough layer were collected farmland in Ningxia, parameters pH, organic carbon, mechanical composition determined. A field-scale estimation model was constructed using multiple linear regression machine...
A precise assessment of the health risks posed by cadmium （Cd） contamination in agricultural products from regional farmland is crucial for informed pollution prevention and control decisions. This study collected 740 pairs soil product samples Ningxia, focusing on Cd content detection. The evaluation encompassed characteristics assessed associated risk human ingestion. Additionally, environmental benchmark values specific to area were established. results showed that pH levels across...
The main objective of this study was to develop a nondestructive method for monitoring cotton growth and N status using digital camera. Digital images were taken the canopies between emergence full bloom. green red values extracted from then used calculate canopy cover. cover closely correlated with normalized difference vegetation index ratio measured GreenSeeker handheld sensor. Models calibrated describe relationship three properties crop (i.e., aboveground total content, LAI, biomass)....
The objectives of this field experiment were to study the growth characteristics and yield potential rice plants under non-flooded irrigation in arid area. Non-flooded treatments included drip with plastic mulching (DIs), furrow treatment (FIM) non-mulching (FIN). Conventional flooded cultivation (F) was check (CK). four differed amount water applied before after panicle initiation. Root length density, leaf dry weight, shoot weight root activity generally higher non-flood-irrigated...
Heavy metal pollution in farmland soil can affect the growth, development, and yield of vegetable crops, as well quality taste vegetables, be continuously transmitted enriched through food chain, which ultimately poses a certain hazard to human health long term. Therefore, order investigate distribution characteristics heavy metals after years multi-crop planting vegetables supplied Hong Kong, predict their ecological risks, analyze causes formation, 477 surface samples fields Kong Ningxia...
Nonflooded irrigation is an important water-saving rice cultivation technology, but little known on its photosynthetic mechanism. The aims of this work were to investigate characteristics during grain filling stage under three nonflooded treatments: furrow with plastic mulching (FIM), nonmulching (FIN), and drip (DI). Compared the conventional flooding (CF) treatment, those grown in treatments showed lower net rate<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:mo...
The farmland environment is directly related to the quality and safety of agricultural products. In order understand characteristics main influencing factors heavy metals in soil Yellow River irrigation area Ningxia, sampling monitoring were conducted for five consecutive years from 2017 2021, distribution correlation analyzed. pollution status potential ecological risks evaluated, sources results showed that average values Pb, As, Zn, Ni, Cu, Hg, Cr, Cd Ningxia 19.74, 11.67, 66.88, 29.09,...
The application of nitrogen (N) fertilizer not only increases crop yield but also improves the N utilization efficiency. critical concentration (Nc) can be used to diagnose crops’ nutritional status. Nc dilution curve model maize was calibrated with leaf dry matter (LDM) as indicator, and performance for diagnosing status further evaluated. Three field experiments were carried out in two sites between 2018 2020 Ningxia Hui Autonomous Region a series levels (application from 0 450 kg ha−1)....
Heavy metals are characterized by toxicity，non-biodegradability，and accumulation in the food chain；hence，o distribution of heavy farmland soils and crop safety have attracted much attention. A total 1 274 soil samples were collected from Ningxia 2017 to 2021 bioconcentration coefficients used based on analysis elemental contents Zn，Cr，Ni，Cu，Pb，As，Cd，and Hg. The ecological risk index correlation characterize metal content health assessment soil-crop system Ningxia. results showed that study...

To provide a theoretical reference to nitrogen fertilizer management for maize and eco-enviromental protection in the irrigated area of Ningxia, we established critical concentration (Nc) dilution curve under drip-irrigated condition. The nutrition index (NNI) was deduced from Nc model, diagnose feasibility nutrition. Six levels application rates including 0, 90, 180, 270, 360 450 kg·hm-2 were conducted field with variety 'Tianci 19'. During two-year study, NNI model based on leaf dry matter...
Abstract Maize ( Zea mays L.) grain quality is an important economic trait directly determining the market price and application value of maize. In this study, maize starch, protein, oil, fiber concentrations, bulk density were investigated based on a multi‐site experiment across China to determine regional distribution trend its influencing factors. It showed that mean in 73.4%, 9.5%, 4.2%, 3.6%, 77.2 kg hL −1 , respectively. Overall, each nutritional composition concentration did not show...
