Problems solved by technology

The lower limit of the growth temperature of Geliflower is low, and it can tolerate a certain low temperature, but the upper limit of the growth temperature is low, and the high temperature resistance is poor
As the temperature rises in summer, the surface temperature of seawater can reach 32°C in July, August, and September. In order to avoid the high temperature that may easily cause the rotting of agaric, the sea area often spends the summer indoors, which leads to an increase in the cost of cultivation and seriously affects the cultivation of summer crops. The yield of Glycyrrhizae, and temperature is the determinant factor affecting the production and breeding of Glycyrrhizae

Abstract

The invention discloses a cultivation method of high-temperature-resistant gelidium amansii and belongs to the technical field of gelidium amansii study and development application. High-temperature-resistant gelidium amansii can be obtained by accurate screening through gradient high-temperature stress, low-temperature culture and high-temperature screening after mutagenization, and the method ishigh in repeatability, reasonable and easy to implement and convenient and quick in application. Gelidium amansii obtained by cultivation can normally grow at 32 DEG C and is high in sea area breeding growth speed. High-temperature-resistant gelidium amansii mutant obtained by induced cultivation enables gelidium amansii breeding enterprises to realize gelidium amansii summer normal breeding without changing a breeding mode by the gelidium amansii breeding enterprises, breeding period is prolonged, year-round production bearing can be realized by the gelidium amansii enterprises, and economicbenefit of gelidium amansii industry is increased greatly.

Description

technical field [0001] The invention relates to a method for cultivating high-temperature-resistant rock lily, belonging to the technical field of research, development and application of rock lily. Background technique [0002] Gelidium amansii belongs to Rhodophyta (Rhodophyta) True red algae (Florideae) Gelidiales (Gelidiales) Gelidiaceae (Gelidiaceae) Gelidium (Gelidium), algal body is purple red or reddish yellow, erect clusters Generally 10-25cm high. Geliflower is a treasure of the sea, rich in nutrients, containing calcium, magnesium, potassium, sodium and various inorganic salts, polysaccharides and other ingredients, it has been collected and eaten by the coastal masses of our country long ago. The content of agaric agar is usually more than 30%, which is the main raw material seaweed for making agar. Agar can also be produced from Gracilaria, chicken feathers, seaweed, etc., but in terms of its color, transparency, hardness, taste and quality. They are not as go...
