Embodiment Construction

[0015] The following examples will further illustrate the present invention.

[0016] (1) At the beginning of September, when picking seedlings of Porphyra spores in the altar, two sets of net curtains were picking seedlings at the same time, and placed them in the sea area for cultivation.

[0017] (2) In late September, when the Porphyra algae grow to 2-4cm, one set of net curtains is taken back from the sea and placed in a cool and ventilated place to dry until the moisture content is 15%-20%. , 0.2mm thick transparent polyethylene bag sealed and packaged, first placed in a quick freezer to quickly cool down to -20°C, and then moved to a freezer at -18~-22°C for refrigerated storage and standby; another set of mesh curtains was kept Cultivation continued on the floating raft.

[0018] (3) In the first ten days of November, after the first batch of laver was harvested for 3 months, the cold storage net was taken out of the cold storage to replace the curtain, and the second...

Abstract

The invention discloses a porphyra haitanensis refrigeration net curtain exchanging cultivation method, relates to porphyra haitanensis, and provides a technical method for preventing diseases, stabilizing production and improving yield and quality in porphyra haitanensis cultivation. The method comprises the following steps: 1) when porphyra haitanensis conchospore are picked with seedlings in autumn, two sets of net curtains are synchronously used for picking the seedlings, and are cultivated in a sea area; 2) when porphyra haitanensis fronds grow to 2-4 cm, one set of net curtain is left on a buoyant raft for continuous cultivating, and the other set of net curtain is recovered from the sea, is put in a cool ventilated place for airing, and is sealed and packed by bags; 3) the packed net curtain is put in a rapid freezing library for cooling to -20 DEG C, then is moved to the freezing library of -18 to -22 DEG C for refrigerating and preserving; 4) after the high temperature period of the sea area or the disease bad period or the finish of first harvest of the porphyra haitanensis in late November, the freezing net is taken out from the freezing library for exchanging the curtain for conducting the second cultivation production of the porphyra haitanensis. The method has the advantages of simple operation, no need of complex equipment, wide application range and prominent economic benefit.

Description

technical field [0001] The invention relates to altar laver, in particular to a cultivation method for altar laver refrigeration net-changing curtain. Background technique [0002] Pyropia haitanensis is one of the two main species of laver artificially cultivated in my country. It is native to the coast of Fujian Province and is a unique warm temperate species in my country. Since the success of artificial cultivation in the 1960s, the cultivation area of ​​Porphyra laver has been continuously expanded, and it has become one of the main targets of mariculture in southern my country, and its output accounts for more than 75% of the total production of laver in the country. [0003] In the traditional cultivation method of Porphyra laver in my country, due to changes in sea conditions and climatic conditions, Porphyra fronds are prone to physiological and bacterial disease rot, so that Porphyra production cannot be carried out as planned, and the light ones reduce production,...
