Problems solved by technology

[0003] Gentiana safflower is a typical alpine plant that likes cold climates and has strong cold resistance; the temperature requirements are not strict during the growth process, but when the seeds germinate, there must be suitable temperature and certain light conditions, otherwise the seeds will germinate The rate is very low, which has seriously restricted people's research and utilization of this excellent resource
[0004] At present, few people have been involved in the research on the germination of gentian safflower seeds, and there is no precedent for large-scale artificial planting of gentian safflower

Abstract

The invention provides a method for promoting germination of seeds of Gentiana rhodantha and seedlings of the Gentiana rhodantha and relates to the technical field of plant seed treatment. The provided method for promoting germination of the seeds of Gentiana rhodantha comprises steps as follows: preparation of a seed treating fluid, seed soaking before seed germination, germination and budding and the like. As for the conditions that research about seed germination of Gentiana rhodantha is rare and large-area artificial planting of the Gentiana rhodantha does not exist, the innovative germination and seedling emergence method is provided, a foundation is provided for artificial planting of the Gentiana rhodantha, and sustainable utilization of Gentiana rhodantha resources is further promoted.

Description

technical field [0001] The invention relates to the field of plant seed treatment, in particular to a method for promoting the germination of gentiana safflower seeds and seedlings thereof. Background technique [0002] Gentiana rhodantha, also known as Gentiana, Tubalian, September flower, Xingxiu flower, cold wind blowing or Xuelimei, is a plant of the genus Gentiana in the Gentianaceae family. It grows in high mountains at an altitude of 570 to 1750 meters. Shrubs, grasslands and undergrowth are newly recorded species in the 2015 edition of the Pharmacopoeia of the People's Republic of China. Gentiana safflower is used as medicine with roots and whole plants. It tastes bitter, cold in nature, and returns to the liver and gallbladder meridians. It has the effects of clearing heat and dampness, reducing inflammation, relieving cough, and detoxifying. Traditional Chinese medicine is often used in acute jaundice hepatitis, dysentery, infantile pneumonia, bronchitis, bronchia...
