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.

“…The collected soil samples were naturally air-dried, sieved separately, and ground for analysis and testing [14][15]. The test content is as follows: using different concentrations of EDTA-Na2 and FeCl3 to analyze the removal efficiency of these two reagents on soil heavy metals, select the reagent with better effect, and then mix it with distilled water, biochar, slaked lime, and organophosphate solubilizing bacteria OPW2-6 Comparison of other remediation techniques, test soil pH value to compare the remediation effect [16][17].…”

Microorganisms also play an important role in soil ecosystems. Microorganisms can adsorb heavy metals in soil. Therefore, microbial remediation technology is widely used in the remediation of heavy metal-contaminated soils. It is of great significance to carry out research on soil microbial ecological effects in polluted areas to solve the problem of remediation and improvement of contaminated soil. This paper collects soil samples contaminated by heavy metals in a certain area, and measures the panel data such as pH value, electrical conductivity, and heavy metal content of the soil samples, and then uses microbial remediation technology to remediate the contaminated soil, and estimates the analysis results through the combined removal of heavy metals and soil remediation. It was found that the organophosphate-solubilizing bacteria OPW2-6 could increase the soil pH, thus improving the soil properties and achieving a good remediation effect.

“…Vetiver grass (Chrysopogon zizanioides (L.) Roberty), a native species from India, is a perennial plant from tropical and subtropical regions and belongs to the family Poaceae. It is widely known and used due to its high performance in ecological restoration programs, as well as its effectiveness in the control and prevention of erosive processes since it presents good resistance to shear stress (TRUONG;LOCH, 2004;NG et al, 2019;ETTBEB et al, 2020). The versatility of vetiver grass use has received much interest, with emphasis on its biotechnical characteristics for use in slope stabilization works, its contribution to the increase of soil cohesion and its high adaptability to various edaphoclimatic conditions (HOLANDA et al, 2012;ARAÚJO FILHO et al, 2015;MACHADO et al, 2015;COSTA et al, 2020).…”

The use of organic fertilizers facilitates the production of plant species compared to industrial fertilizers, with a remarkable contribution to soil and water conservation through soil structuring. Vetiver grass (Chrysopogon zizanioides (L.) Roberty) is widely used in soil bioengineering projects to stabilize slopes, increasing the resistance of the soil to shear strength. The objective of this study was to evaluate the effect of the development of vetiver grass at different doses of organic fertilizer on soil stabilization. An experimental test was carried out in a greenhouse, in pots, using the following doses of organic fertilizer: T0-0 g (control); T1-135 g; T2-270 g and T3-405 g of organic fertilizer. Shoot Dry Matter (SDM), Root Dry Matter (RDM), Root Length (RL), Number of Tillers per Plant (NT) and Plant Height (PH) were evaluated. The collected data were submitted to regression analysis at 5% probability. The analysed variables showed increasing values as greater amounts of organic fertilizer, leading to an increase in soil nutrient availability and, consequently, to improved plant development.
