A Detailed Explanation of the Principle of Foliar Fertilizer Absorption by Plant Leaves
The main function of leaves is to carry out photosynthesis using solar energy, while also performing certain biochemical transformations on the synthesized products and transporting them to other organs. Leaves can also continuously exchange substances with the external environment. The form and mechanism of nutrient absorption by the leaf surface are similar to those of roots, and conform to the five basic principles of rational fertilization...
