For quality control of buckwheat, fingerprint-efficacy study of buckwheat was carried out in this work. 2,2′-Bipyridyl,2,2-diphenyl-1-picrylhydrazyl radical (DPPH) scavenging activity of the buckwheat was measured using UV spectrometer. Chemical fingerprints of tartary buckwheat from 29 different so...

This paper proposes a harmonic screening-based method for calculating the cogging torque of the axial flux permanent magnet synchronous motor. The magnetic field energy in the air gap is derived from the air gap flux and the magnetomotive force of rotor. The cogging torque is then obtained using the...

The corn borer is a world-wide agricultural pest. In this study, a high-efficiency RNAi method was explored to knock down the neuropeptide F (NPF) to determine if NPF regulates larval feeding in the Asian corn borer, Ostrinia furnacalis. Results showed that the expression peaks of npf mRNA in both m...

Microbes are decomposers of crop residues, and climatic factors and residue composition are known to influence microbial growth and community composition, which in turn regulate residue decomposition. However, the succession of the bacterial community during residue decomposition in Northeast China...

The essential and toxic element concentrations in buckwheat were analyzed by inductively coupled plasma optical emission spectrometer (ICP-OES). The concentration data were subjected to common chemometrics analyses, including correlation analysis (CA), principal component analysis (PCA) and hierarch...

As an emerging endocrine-disrupting agent and structural analog of bisphenol A (BPA), bisphenol B (BPB) raises significant concerns due to its potential to induce male reproductive toxicity. Despite its presence in maternal bodily fluids, the effects of BPB exposure on the reproductive system and it...

Forest transformation commonly occurs in subtropical areas due to extensive human disturbance. However, we know little about how forest transformation may affect the soil water-holding capacity. Here, we evaluated the effects of forest transformation from natural forests to secondary forests, Castan...

Understanding the spatial-temporal dynamics of crop nitrogen (N) use efficiency (NUE) and the relationship with explanatory environmental variables can support land-use management and policymaking. Nevertheless, the application of statistical models for evaluating the explanatory variables of space-...

Phosphorus (P) is one of the most widely occurring nutrients for development and growth of wheat. In this study, the effects of P application amount on grain yield, protein content, and phosphorus use efficiency (PUE) were studied by agronomic management of P fertilizer on spring weak-gluten wheat (...

To understand the long-term effects of combined organic and chemical nitrogen fertilization on soil organic C (SOC) and total N (TN), we conducted a 30-year field experiment with a wheat–maize rotation system on the Huang-Huai-Hai Plain during 1990–2019. The experimental treatments consisted of five...

Quantification of currently attainable yield and fertilizer requirements can provide detailed information for assessing the food supply capacity and offer data support for agricultural decision-making. Datasets from a total of 5 408 field experiments were collected from 2000 to 2015 across the major...

Blast resistance and grain quality are major problems in hybrid rice production in China. In this study, two resistance (R) genes, Pi46 and Pita, along with the gene Wxb, which mainly affects rice endosperm amylose content (AC), were introgressed into an elite indica restoring line, R8166, which has...
