2results about How to "Reduce cadmium content" patented technology

This invention relates to a method for promoting the germination of buckwheat seeds under cadmium stress and alleviating cadmium toxicity during the seedling stage. The method includes treating buckwheat seeds with a melatonin reagent before germination. The method involves contacting the plant seeds with a melatonin solution at a concentration of 100-500 μmol / L. The method provided by this invention can effectively improve the germination potential and germination rate of buckwheat seeds under cadmium stress, enabling uniform and rapid germination. This invention solves the important problem of how to ensure normal germination of buckwheat in cadmium-contaminated soil in agricultural production and has significant application value in production. This is likely because pretreatment with a melatonin reagent can induce the expression of antioxidant enzyme activity, scavenge the large number of free radicals generated by cadmium stress, alleviate oxidative stress, reduce oxidative damage, and maintain a low level of membrane lipid peroxidation in the seeds, thereby promoting normal seed germination.

This invention discloses a liquid microalgae fertilizer that can reduce the cadmium content of rice. The liquid microalgae fertilizer for reducing cadmium content in rice is composed of the following components by mass percentage: 50%-75% concentrated algae solution, 5%-12% humic acid, 2%-8% potassium fulvate, 0.1%-0.5% xanthan gum, 0.1%-0.5% sodium alginate, and the remainder being water.
