“The Effect of Potassium Fulvic Acid: Changing Plant Physiological Characteristics and Enhancing Plant Stress Resistance” explains the effect of potassium fulvic acid on changing plant physiological characteristics and enhancing plant stress resistance, but its changes in plant stress resistance are not limited to this. It can also enhance plant stress resistance by changing the plant growth environment.
According to experimental data, under salt stress conditions, the application of potassium fulvic acid can reduce the electrical conductivity of the soil medium, promote the growth of Norway maple and ginkgo seedlings, and increase their chlorophyll content; potassium fulvic acid can increase soil aggregate content and soil compaction. Solidity, water holding capacity, cation exchange capacity, promote plant growth.
Under drought stress conditions, organic acids secreted by plant roots can locally damage humic acid colloids, causing them to release individual growth regulatory molecules. These molecules are small enough to penetrate the cell wall matrix and enter the cell membrane, thereby affecting gene expression. and enzyme activity.
In addition, potassium fulvicate can inhibit plant pathogenic bacteria under biotic stress conditions. Studies have confirmed that potassium fulvicate can not only reduce the survival rate of conidia of soil fungi Alternaria, Fusarium culmorum and Fusarium oxysporum, but also inhibit the elongation of conidial hyphae and affect conidial reproduction. Inhibition is its main mode of action. Through the above effects of potassium fulvic acid, the incidence of root disease is significantly reduced.
Based on the two articles, potassium fulvicate can enhance the stress resistance of plants by improving the internal physiological characteristics of plants and the external growth environment of plants. It can effectively solve various problems faced by plants during their growth. It is a natural green and efficient agricultural products.
