This invention relates to the field of crop cultivation technology and discloses a high-temperature-resistant cultivation technique for mung beans. The technique includes immersing mung bean seeds in a calcium chloride aqueous solution in the dark, then removing them and allowing them to air dry naturally until the seed coat is free of visible water before sowing them in the field. During the seedling to initial flowering stage, the relative soil moisture content is controlled. During the initial flowering to pod-setting stage, when a weather warning indicates continuous high temperatures, a metastable silicic acid and proline composite sol is sprayed onto the plant canopy leaves. The composite sol is prepared by protonating potassium silicate in an acidic substrate containing ascorbic acid, thus halting the polymerization process. Pre-sowing seed soaking promotes calcium ion absorption and initiates stress-resistance signal transduction, improving the seedling's basic heat resistance. Spraying the sol utilizes the dehydration and condensation of silicic acid to form an inorganic network covering layer, limiting water loss. Combined with proline penetration into mesophyll cells for osmotic regulation, this maintains leaf moisture content and ensures a certain number of pods.
