The invention discloses a cultivation method for narcissi. The method comprises the following steps that 1,
plant division is conducted on the narcissi, each
narcissus plant comprises 2 seedlings, roots of the narcissi obtained after
plant division are wrapped by gauze and placed in a
nutrient solution to be soaked for 2-3 days, and the narcissi are taken out and air-dried for use; 2, a
narcissus cultivation medium is prepared from
vermiculite,
leaf mold,
moss,
fly ash,
feather powder, wormcast, waste peel, pine needles and a slow release
fertilizer water retaining agent, and 200-300 mL of a
carbendazim solution is sprayed to every
square meter of the cultivation medium 1-2 days before
narcissus cultivation. According to the method, due to the fact that the cultivation medium contains the slow release
fertilizer water retaining agent, has the water retaining property and air permeability and can slowly release nutrients, other
fertilizer does not need to be added in the planting process, and growth of the narcissi can be quickly accelerated; due to the fact that the slow release fertilizer contains seaweed fertilizer which contains multiple natural auxins, growth of the narcissi can be promoted, the
growth cycle is shortened, and flowering of the narcissi can be promoted to make the narcissi to enter a flowering period in advance.
