“…Chen et al (2019) reported that the soil Cd, Hg, Cr, and Ni contents in Minfeng County, Xinjiang, China were 1.147, 1.124, 1.116, and 1.041 times of the background values of the soil in Xinjiang, respectively. Therefore, the ecological risk of soil heavy metal pollution is very high in Xinjiang, China (Liu et al, 2020).…”

IntroductionCotton straw biochar (biochar) and compound Bacillus biofertilizer (biofertilizer) have attracted wide attentions in the remediation of heavy metal-contaminated soils in recent years. However, few studies have explored the metabolomics of lateral roots of Cd-stressed cotton to determine the mechanism of biochar and biofertilizer alleviating Cd stress.MethodsIn this pot experiment, biochar and biofertilizer were applied to the soils with different Cd contamination levels (1, 2, and 4 mg kg-1). Then, the responses of cotton root morphology, vitality, Cd content, and antioxidant enzyme activities were analyzed, and the mechanism of biochar and biofertilizer alleviating Cd stress was determined by metabolomic analysis.ResultsThe results showed that exogenous Cd addition decreased the SOD and POD activities in cotton taproot and lateral root. Besides, with the increase of soil Cd content, the maximum Cd content in taproot (0.0250 mg kg-1) and lateral root (0.0288 mg kg-1) increased by 89.11% and 33.95%, respectively compared with those in the control (p< 0.05). After the application of biochar and biofertilizer, the SOD and POD activities in cotton taproot and lateral root increased. The Cd content of cotton taproot in biochar and biofertilizer treatments decreased by 16.36% and 19.73%, respectively, and that of lateral root decreased by 13.99% and 16.68%, respectively. The metabolomic analysis results showed that the application of biochar and biofertilizer could improve the resistance of cotton root to Cd stress through regulating the pathways of ABC transporters and phenylalanine metabolism.DiscussionTherefore, the application of biochar and biofertilizer could improve cotton resistance to Cd stress by increasing antioxidant enzyme activities, regulating root metabolites (phenols and amino acids), and reducing Cd content, thus promoting cotton root growth.

For the current nuclear radiation problem in society, it is very important to monitor the content of radionuclides in the atmosphere. The large flow total suspended particulate (TSP) sampler is the key equipment to monitor radionuclides. In this paper, a large flow total suspended particulate intelligent sampler is developed, which has high sampling accuracy, stable and reliable operation, and forms a complete set of automatic membrane changing particulates matter analyzer with analyzer and membrane sending mechanism, realizing 24-hour unattended automatic membrane changing sampling and analysis, and is used to collect suspended particulate matter in air in radiation monitoring stations and scientific research institutes at all levels to analyze the radionuclides: total α, β and γ and so on.
