Embodiment Construction

[0014] The specific embodiment and experimental process of the utility model are described in detail below.

[0015] When the altar laver production entered the middle and later stages, the applicant stripped some altar laver fronds of different individual sizes from artificial breeding buoys in the Shenwo sea area of ​​Longhai County, Fujian Province, and cultured them in the Gulangyu sea area of ​​Xiamen for many times. Observe its growth, the results are shown in Table 1 below.

Abstract

The Porphyra haitanensis seedling preserving and net changing cultivation method includes taking out Porphyra haitanensis seedling net from sea, preserving up to 60 days while spraying water twice a day, and setting in water for further cultivation. The said method can prolong the Porphyra haitanensis cultivating period for 2 months, raise the yield of Porphyra haitanensis and make best utilization of the sea region suitable for cultivation in spring and summer.

Description

technical field [0001] The invention relates to a method for cultivating altar laver seedlings, in particular to a method for preserving and changing nets for altar laver seedlings. Background technique [0002] Altar laver (Porpnyra haitanensis T.J.Cnang et B.F.Ineng) is naturally distributed on some reefs in the intertidal zone along the southeast coast of my country. Fujian has the largest aquaculture scale. In 2003, the aquaculture area of ​​the whole province was 10,592 hectares, and the production technology is becoming more and more perfect. [0003] However, due to diseases, environmental factors, and other factors, the production cycle of altar laver has been continuously shortened. For example, in the 1960s, it can be cultivated until March, and in some places it can be cultivated until mid-May. Now, most of the altar laver is cultivated and produced around New Year's Day or later. It was over earlier. The shortening of production cycle makes the output of altar l...
