Objective: To discuss the suitable water and nitrogen management mode in artificial cultivation of Chuzhou Chrysanthemum morifolium.
Methods: According to two factors quadratic regression rotation design experience, pot experiment was conducted.
Results: There were remarkable effects of water and nitrogen coupling on inflorescence number, yield and overground part biomass of Chuzhou Chrysanthemum morifolium, and there were significant positive interaction between water and nitrogen. Effects of water on early-term inflorescence yield and overground part biomass of Chuzhou Chrysanthemum morifolium were higher than that of nitrogen fertilizer, but the effect on total inflorescence yield was opposite.
Conclusion: Considering for the fresh inflorescence yield, the suitable water and nitrogen management mode is to keep 93% of the water holding capacity and nitrogen fertilizer (N) 0.34 g/kg of Chuzhou Chrysanthemum morifolium in pot experiment, and as for the dry inflorescence yield, the suitable water and nitrogen management mode is to keep 75% of the water holding capacity and nitrogen fertilizer (N) 0.2 g/kg.

This work quantifies, through use of molecular dynamics (MD) simulations, the kinetic rates of physical surface processes occurring at a plasma-water interface. The probabilities of adsorption, absorption, desorption and scattering were computed for O, NO, NO, NO, OH, HO, HNO, HNO, and NO as they interact with the interface at three water temperatures: 298 K, 323 K, and 348 K. Species are categorised into the short-residence group (O, NO, NO, and NO) and the long-residence group (OH, HO, HNO, HNO, and NO) based on their mean surface residence time.

Grazing can alter the physicochemical properties of soil and quickly influence the composition of microbial communities. However, the effects of grazing intensity on fungal community composition in different soil depth remain unclear. On the Inner Mongolia Plateau, we studied the effects of grazing intensity treatments including no grazing (NG), light grazing (LG), moderate grazing (MG), heavy grazing (HG), and over grazing (OG) on the physicochemical properties and fungal community composition of surface (0-20 cm) and subsurface (20-40 cm) soil layers.

Although the separate effects of water and nitrogen (N) limitations on forest growth are well known, the question of how to predict their combined effects remains a challenge for modeling of climate change impacts on forests. Here, we address this challenge by developing a new eco-physiological model that accounts for plasticity in stomatal conductance and leaf N concentration. Based on optimality principle, our model determines stomatal conductance and leaf N concentration by balancing carbon uptake maximization, hydraulic risk and cost of maintaining photosynthetic capacity.

Herein, highly fluorescent sulfur and nitrogen co-doped carbon dots (N, S-CDs) had been employed as a fluorescent probe to analyze Cu in drinking water. The biogenic creatinine is known to form a stable complex with Cu; hence, it was rationally selected as a bioinspired nitrogen substrate for the first time to enhance N, S-CDs selectivity towards Cu. Moreover, the literature was surveyed to guide the selection of sulfur and carbon sources to optimize N, S-CDs quantum yield (QY), so thiourea and disodium edetate are co-carbonized with biogenic creatinine at 270°C for 40 min and characterized using different techniques.
