Seedling raising method for non-shell protonema cell of laver

Abstract

The present invention discloses no-shell filament cell laver seedling growing process. In the laver seedling growing room, and inside the culture container in the optimized temperature, lighting, nutritious and water motion conditions obtained through experiment, the cultured suspension filament cells are controlled to grow to the cell density of 5-10 g / L synchronously. The culture container is box on shelf. In the later stage, the great amount of cell generated conchospores are collected and transferred into sieve net bag, and cells are flushed with flow water at night so as to spread great amount of conchospores in the day. The present invention makes it possible to grow laver seedlings in large scale, high efficiency and low cost. The process is suitable for cultivating laver of different varieties.

Description

technical field

[0001] The invention relates to a laver cultivation technology, in particular to a method for cultivating seaweed seedlings without shell filaments. Background technique

[0002] Porphyra is the most important artificially cultivated seaweed in the world, and its output value accounts for two-thirds of all cultivated seaweed. So far, more than 99% of the cultivated laver at home and abroad have adopted the traditional shell filamentous seedling technology. The principle is that the fruit spores released by mature laver can penetrate into the shell and grow into shell filaments. After 6 to 10 months When the growth and development reach maturity, the ascospores are emitted and are the seedlings of laver. Cultivating 1 hectare (equivalent to 15 mu) of seaweed requires cultivating 15 square meters of shell filaments in an indoor pool on land, which is called seedling cultivation. There are problems such as time-consuming, laborious, low seedling raising effici...
