Embodiment Construction

[0022] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] See figure 1 , shown in this figure is the flow chart of the first embodiment of the Porphyra half-leaf seedling raising method of the present invention.

[0024] Such as figure 1 Shown, this embodiment carries out the process of raising seedlings to Porphyra half leaf specifically as follows:

[0025] Step 11: Obtain the preserved half leaf laver nutrient algal filaments.

[0026] Porphyra half-leaf vegetative algae filaments are generally stored in culture medium, and temperature, light and photoperiod need to be controlled during the preservation process to maintain the state of vegetative algae filaments.

[0027] Step 12: Cultivate the vegetative algae filaments in the culture solution, and control the culture conditions until filaments with a set proportion of sporangia branches are formed. ...

Abstract

The invention discloses a semi-leaf laver seedling cultivating method. The method includes the following steps that semi-leaf laver nutritious trichome is obtained; the semi-leaf laver nutritious trichome is cultivated in nutritious liquid until a protonema of a sporangium branch with the set proportion is formed and the cultivating conditions include that the temperature ranges from 20 DEG C and 30 DEG C, the light intensity ranges from 1000 lx and 2600 lx, the lighting period is 10 hours to 16 hours and the nutritious liquid sea water ratio ranges from 1.026 to 1.031. The protonema of the sporangium branch with the set proportion is placed on an attachment basal body and stimulated by water currents until conchospores of which the density reaches the seedling collecting requirement are formed and seedling cultivating of the semi-leaf laver is finished. Thus, the problem that the seedlings of the semi-leaf laver can not be rapidly and efficiently cultivated with the prior art is solved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for raising laver seedlings, more specifically, relates to a method for raising half-leaf laver seedlings. Background technique [0002] Porphyra is a large seaweed with high nutritional and economic value. There are many types of Porphyra, but currently only Porphyra altar and Porphyra zebra are cultivated in my country. Porphyra altar is a species adaptable to high temperature and is mainly cultivated along the coasts of Fujian and Zhejiang provinces, while Porphyra variegata is a species adaptable to low temperature and is mainly cultivated on a large scale in Jiangsu. Porphyra altar and Porphyra variegata are species in the intertidal zone, which require periodic dew and sun exposure to remove enteromorpha, diatoms and other algae and diseases. In this way, the natural conditions for cultivation in sea areas are relatively high. Therefore, only semi...
