The invention provides a method of cultivating
eustoma grandiflorum
flowering plant seedlings. The method is characterized by comprising the steps that A,
peat soil,
perlite and
vermiculite of
seedling culture matrix are prepared by proportion of 7:2:1; B, seed is sowed into potted trays,
coating seed is directly sowed without being processed in the mode of about 800 grains per milliliter, naked seed of about 10000-15000 grains per milliliter are soaked for one hour through
carbendazim of 50% with liquid of 500 times, after soaking, the naked seed is cleaned by clear water, mixed with fine sand with the proportion of 1:10, and sowed, the potted tray is used for fine quantity
sowing, the naked seed of one to two grains for one pot is sowed, and seedlings are formed in a one-time mode; C, little seedlings are managed with the measures of controlling temperature,
humidity and light, and managing watering and
fertilizer applying; and D, pest and
disease damage is controlled,
drug agents of grey mould,
pyrimethanil and the like are diluted by water with the proportion of 10:200 and used for treating the pest and
disease damage such as
root rot, gray mold and spiders. According to the method, materials are easy to take, cost is low,
fertilizer applying effect is good, a rate of survival is high, and positive facilitation on production is achieved.
