Enhancing nitrogen use efficiency (NUE) in crop plants is an important breeding target to reduce excessive of chemical fertilizers, with substantial benefits farmers and the environment. In Arabidopsis (Arabidopsis thaliana), allocation more NO3 − shoots was associated higher NUE; however, commonality this process across plant species have not been sufficiently studied. Two Brassica napus genotypes were identified high low NUE. We found that activities V-ATPase V-PPase, two tonoplast...

Abstract Controlled-release nitrogen fertilizer (CRNF) can effectively enhance crop yields and raise the efficiency of in agroecosystems. In present study, volatilization NH 3 was determined by airflow enclosure chamber technique after application different CRNF rates double-cropping rice fields southern China for continuous years. The early late season (ESR LSR) were cultivated each year. results showed that total losses ranged from 25 to 56 kg N ha −1 ESR 32 61 LSR. loss applied 12 29% 27%...

Semantic segmentation, a fundamental task in remote sensing, plays crucial role urban planning, land monitoring, and road vehicle detection. However, compared to conventional images, multispectral sensing images present significant challenges due large-scale variations, multiple bands, complex details. These manifest three major issues: low cross-scale object segmentation accuracy, confusion between band information, difficulties balancing local global information. Recognizing that...

Abstract BACKGROUND Urea is commonly over‐applied as a nitrogen (N) fertilizer to crops in southern China and has low utilization efficiency result of the high precipitation temperatures this region. This led need optimize management N use maize on subtropical hilly uplands China. RESULTS We investigated effects applying different amounts form polymer‐coated urea (PCU) yield gaseous losses from soils NH 3 2 O. The field plots used trial had zero‐added (0 kg ha −1 ), addition (240 ) four...

Controlled-release urea (CRU) has better characteristics than conventional for synchronizing nitrogen (N) release with plant uptake. Understanding the effects of CRU on crop yield and N use efficiency (NUE) long been key to evaluate performance CRU. A long-term experiment over five consecutive years was conducted in Changsha, Hunan Province, China, investigate polyethylene-coated a 90-d period NUE double rice (early late crops are grown same year), amount residual soil mineral soil–plant...

Oilseed rape (Brassica napus L.) is a crucial source of edible oil and livestock feeding, promising biofuel crop. The increasing demand for oilseed requires strategies to increase yield while retaining quality. Field experiments were performed in southern China evaluate the impacts fertiliser level planting density on dry matter accumulation, seed protein content (%) (per ha), quality, profitability rape. Fertiliser treatments contained nitrogen (N), phosphorus (P), potassium (K), sulfur (S)...

(1) Background: the broadcast is an outdated fertilization method with a low fertilizer-utilization rate and environmental problems, which seriously restricts development of agriculture. (2) Methods: Under machine-transplanted rice side-deep (MRSF) mode, five treatments were applied: 0 cm (D0), 5 (D5), 7.5 (D7.5), 10 (D10), comprising four different depths fertilization, no (CK). The yield, accumulation N P in straw grains rice, concentrations surface water, ammonia (NH3) volatilization,...

Simultaneously realizing the efficient generation of H2O2 and degradation pollutants is great significance for environmental remediation. However, most polymeric semiconductors only show moderate performance in molecular oxygen (O2) activation due to sluggish electron-hole pair dissociation charge transfer dynamics. Herein, we develop a simple thermal shrinkage strategy construct multi-heteroatom-doped carbon nitride (K, P, O-CNx). The resultant K, O-CNx not improves separation efficiency...

The Type-II codebook in Release 17 (R17) exploits the angular-delay-domain partial reciprocity between uplink and downlink channels to select part of ports for measuring feeding back channel state information (CSI), where performance existing deep learning enhanced CSI feedback methods is limited due deficiency sparse structures. To address this issue, we propose two new perspectives adopting improve R17 codebook. Firstly, considering low signal-to-noise ratio channels, utilized accurately...

Nitrogen (N) and phosphorus (P) losses from agroecosystems are dominant nonpoint pollution. To minimize the of N P, optimal depth fertilization was explored using a soil column study with red paddy as research objects. The P were measured under five depths (0, 5, 7.5, 10, 12.5 cm) well no fertilization. results showed that ammonia volatilization significantly decreased increasing within 0–10 cm, there significant difference among 10 no-fertilization treatments. Comparing surface (0 cm), by...

Accurate in-season yield forecasts for field-scale crops are crucial both farmers and decision-makers. Common methods prediction limited by the availability of unknown weather data (process-based crop models) failure to consider formation processes (statistical models based on unmanned aerial vehicle (UAV) images), respectively. Furthermore, previous studies focused only without mulching, yet mulching is an important agronomic approach increase grain in arid areas northwest China. We aim...
