7. The method for preparing artificial tomato seeds as claimed in claim 1, wherein the method comprises the following steps: packaging and treating the tomato seeds: and (3) pelleting and packaging the treated tomato seeds, packaging the prepared artificial seeds by using aluminum foil, and storing the seeds under the low-temperature drying environment condition.
8. The method for preparing artificial tomato seeds as claimed in claim 1, wherein the method comprises the following steps: ultraviolet light irradiation treatment of the tomato seeds: cleaning and drying the tomato seeds soaked with the seed soaking agent, placing the tomato seeds in a breeding room with the ventilation capacity of 20L/min at the indoor temperature of 25-28 ℃, uniformly irradiating the tomato seeds with an ultraviolet lamp once in the morning and at night, each time for 20-30min, cleaning and drying the tomato seeds soaked with the seed soaking agent, placing the tomato seeds in a breeding room with the ventilation capacity of 20L/min at the indoor temperature of 25-28 ℃, uniformly irradiating the tomato seeds with an ultraviolet lamp once in the morning and at the night, each time for 20-30 min.
9. The method for preparing artificial tomato seeds as claimed in claim 1, wherein the method comprises the following steps: the tomato seed accelerated treatment comprises the following steps: soaking the treated tomato seeds in an aqueous solution containing 1-3 parts by mass of gibberellin, 2-5 parts by mass of triacontanol, 2-5 parts by mass of vitamin C, 1-3 parts by mass of vitamin E and 2-5 parts by mass of chitosan for 1-2 hours; irradiating with ultraviolet lamp every 30min for 5-10min while soaking.
