Abstract

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.

Description

technical field [0001] The invention belongs to a method for growing seedlings of eustoma flowers and belongs to the field of biotechnology. Background technique [0002] Eustoma grandiflorum, also known as prairie gentian, is native to Nebraska and Texas in the United States. It is a plant of the Gentianaceae grassland Gentiana, and it is a one-year or two-year herb. Hi warm, humid and sunny. More cold-resistant, not resistant to water and humidity. Introduced to Europe and Japan through crossbreeding and improvement, it has now become a seductive and unusually novel flower. The plant height is 30-100 cm. Leaves alternate, broadly elliptic to lanceolate, almost sessile, leaf bases slightly clasping; leaf surface blue-green. The stamens are obvious, the bracts are narrow and lanceolate, and the petals are imbricate. [0003] The optimum temperature for the growth of eustoma is 15-28°C, and the night temperature during the growth period is not lower than 12°C. When the...
