Method for effectively increasing maturing rate of amphoteric asparagus plants

The invention provides a method for effectively increasing the maturing rate of an asparagus amphoteric plant. The method comprises the following steps: taking an asparagus amphoteric plant as a material, taking a non-germinated bulbil, inducing to form a bulb disc through tissue culture, soaking the bulb disc in high-concentration IBA for a short time, and then transferring into a specific culture medium to induce the bulb disc to rapidly root. The seedlings are directly transplanted to a greenhouse from March to April of the next year, part of old stems on the ground are removed at the end of August, potash fertilizer is applied, and watering is conducted. Fertilizing during the period from the beginning of September when new and tender stems germinate out of soil to lateral branch expansion; from the early flowering stage to the end of the flowering stage, borax, zinc sulfate and brassinolide are sprayed once every three days and are continuously sprayed for three times.
