AI Technical Summary

Technical Problem

Existing technologies are insufficient to effectively alleviate drought stress in wheat, especially during seed germination and growth, when the demand for water and nutrients is insufficient, resulting in low germination rates, limited growth, and severe oxidative damage caused by drought, which affects yield and water use efficiency.

Method used

Seed dressing with silicon quantum dots (SiQDs) combined with application of Bacillus halotolerans GS127 reduces oxidative damage, promotes root development, increases the accumulation of osmotic regulators, and enhances the drought resistance of wheat by regulating multiple mechanisms.

Benefits of technology

It significantly improves wheat growth and yield under drought conditions, enhances water use efficiency, reduces oxidative damage, strengthens wheat drought resistance, and promotes root development and biomass accumulation.

Abstract

The application discloses a planting method for relieving drought of wheat based on combined application of SiQDs seed dressing and halophilic bacillus, and belongs to the technical field of agricultural planting. The application discloses a planting method for relieving drought of wheat based on combined application of SiQDs seed dressing and halophilic bacillus, which comprises the following steps: using silicon quantum dots (SiQDs) for seed dressing treatment of wheat seeds, then planting the seed-dressed wheat seeds in soil, and applying halophilic bacillus agent during the growth of the wheat. The combined application of SiQDs and halophilic bacillus GS127 can better promote the root development of wheat under drought stress, increase the content of proline and soluble sugar in the wheat, reduce the content of malondialdehyde, enhance the drought resistance of the wheat, effectively promote the growth of the wheat, and improve the yield and water use efficiency, and therefore has excellent application potential in the production in agricultural wheat drought areas.
