Congratulations International Symposium on Trace Element Research in Crops and Huazhong Agricultural University

Research on Trace Elements50The Anniversary Commemorative Conference was successfully held

1975 In, Professor Wang Yunhua revealed the physiological mechanism of cotton's "bud but not flower" caused by boron deficiency, marking the formal entry of trace element research in crops in China into a standardized development track. Over the past half century, global research on plant trace element nutrition and applications has achieved rapid development, resulting in a series of breakthrough achievements. These studies not only contribute to the large-scale and high-quality development of the trace element fertilizer industry, but also provide key technical support for ensuring national food security. Recently, the International Symposium on Trace Element Research in Crops and the Trace Element Research at Huazhong Agricultural University50 The "Anniversary Commemorative Conference" was successfully held in Wuhan, Hubei. Beijing Yiketai Ecological Technology Co., Ltd. extends its warmest congratulations on the successful conclusion of the conference.

This conference comprehensively reviewed and summarized the research on trace elements in crops and innovative achievements in the fertilizer industry at home and abroad in recent years, and deeply explored new paths and strategies for trace elements in agricultural green development. The conference is guided by scientific research innovation and industrial demand, extensively integrating high-quality resources from domestic and foreign industry, academia, and research, injecting strong momentum into the green development of agriculture in the new era. Beijing Yiketai Ecological Technology Co., Ltd., as a national high-tech enterprise, focuses on ecology -agriculture-The research and development, promotion, and service of health research monitoring technology adhere to the business philosophy of "to do a good job, we must first sharpen our tools", providing high-quality technical solutions and service support for the research and industrial development of trace elements in domestic crops.

FireFlyFast Element Distribution Imaging Technology

Roots play a crucial role in plant nutrient supply and resistance to excessive metal ion toxicity, but the difficulty of elemental analysis in roots is much higher than in stem tissues: compared to stems and buds, plant roots are smaller and have lower dry matter content, making them difficult to accurately cut and having lower relative content of elements to be analyzed; At the same time, the root samples are soft and juicy, making it difficult to maintain their original structural shape, which poses a great challenge for accurate detection of element distribution. This case adopts dual excitationLIBS technology is used to perform mapping analysis on nano silver particles (diameter 21.7 ± 2.3 nm) in the roots of broad bean seedlings, which can directly detect plant tissue elements in their natural state. This not only achieves high mapping resolution, but also ensures detection sensitivity - this is also the precise analysis of nano particle distribution in plant roots achieved in the field of LIBS technology.

EasyChemFully automatic chemical analyzer

The research team passedA 2 mol/L KCl solution was used to extract effective nitrogen from soil (NO ∝⁻ and NH ₄⁺ are the main inorganic nitrogen forms that plants can directly absorb), and then the EasyChem fully automatic chemical analyzer was used to accurately detect the concentrations of the two types of nitrogen in the extract, providing key data support for comparing the effects of "recycled water (RWW) irrigation" and "well water (WW) irrigation" on soil nitrogen nutrition status in the system.

LC proSeries photosynthetic apparatus

European scholars focus on cadmium（Cd）Research on the nutrient transport mechanism of weeping willows under pollution background reveals that when magnesium is present in the environment（Mg）Iron（Fe）When lacking, in the leaves, stems, and roots of weeping willow clonesCdThe accumulation will significantly increase. The research team further investigated the changes in photosynthetic parameters of plants under various hydroponic conditions, and based on this, speculated that,MgTheFeandCdIt may be absorbed by plant roots through the same transport pathway and transported to the aboveground part, so there may be a competitive absorption effect among the three in the extracellular and symplastic regions of plants.

Chlorophyll Fluorescence Imaging System

Haizhou Elsholtzia is a copper tolerant plant in copper deposit areas of China. A research team from Zhejiang University found that copper toxicity has a much greater inhibitory effect on the electron flow of light adaptation in Elsholtzia haizhou than on non photochemical quenching（The influence of NPQ or dark adaptation on the maximum photochemical efficiency (Fv/Fm); At the same time, it will also alter the aggregation state of the Light harvesting Complex II (LHCII), reduce the accumulation of iron in leaves, and decrease the content of chlorophyll and carotenoids.

The French National Academy of Agricultural Sciences in potatoes YIn the study of antiviral genes in the virome, the antiviral molecular mechanism was systematically validated through various gene editing treatments. Researchers utilizeFluorCamChlorophyll fluorescence imaging technology reflects the damage of viruses to the plant photosynthetic system and synchronously obtains plant photosynthetic phenotype information; At the same time, utilizing itGFPThe fluorescent protein imaging function enables quantitative analysis of virus infection area and accumulation, intuitively revealing the impact of different gene functions on Arabidopsis virus resistance.
