The invention discloses a method for promoting the germination of Trichosanthes seeds, which comprises the following steps: (1) when the peel color of Trichosanthes fruit changes from green to yellow, the Trichosanthes fruit is collected, and the collected Trichosanthes fruit is soaked in tap water for 15 hours , rub the pulp, then soak the Trichosanthes seeds in tap water for 10-12 hours, discard the seeds floating on the water surface, fish out the seeds that sink to the bottom of the water, and dry them in a ventilated place indoors for 2-3 hours; (2) Dry the above-mentioned seeds in the shade The obtained Trichosanthes seeds were placed in an ultra-clean workbench, and the surface moisture was blotted with anhydrous filter paper, then soaked in 75% alcohol for 5 minutes, and then rinsed repeatedly with sterile water for 3-5 times until no alcohol remained on the surface of Trichosanthes seeds. Soak and disinfect with 0.5% copper sulfate solution for 15-20min, then rinse repeatedly with sterile water for 3-5 times until no copper sulfate solution remains on the surface of Trichosanthes seeds; (3) place the above-mentioned treated seeds on double-layer filter paper Then put them into a constant temperature seed germination box at 28°C, and the constant temperature germination process will take 5‑7 days.
