Acidizing fluid for green algae and disease infected cell in porphyra haitanensis cultivation and treating method thereof

Abstract

The invention discloses an acidizing fluid for green algae and a disease infected cell in porphyra haitanensis cultivation and a treating method thereof. A solvent for the acidizing fluid is clean seawater, and solute for the acidizing fluid is at least one of hydrochloric acid and citric acid, wherein the concentration expressed in percentage by weight of the solute in the acidizing fluid is 0.3 to 1.5 percent. The green algae and the disease infected cell can be quickly killed by a treating method of preparing the acidizing fluid, shipping, dipping for 15 to 20 seconds and rinsing, killing effect is better, the killing rate is over 90 percent, and the influence on the growth of the porphyra haitanensis is less. The treating method has the advantages of no restriction of natural condition, labor intensity reduction and the like.

Description

technical field [0001] The invention relates to the treatment of green algae and diseased cells in the culture of algae laver, in particular to the acid treatment liquid and treatment method for the green algae and diseased cells in the culture of algae laver. Background technique [0002] There are two phenomena that often occur in cultivated Porphyra laver. One is the outbreak of large green algae (such as Enteromorpha, etc.) in the sea area where Porphyra laver is cultivated, which competitively inhibits the growth and yield of Porphyra algae; Infected cells appear locally. If the infected cells are not treated in time, the germs in the sore will spread rapidly, and then spread to other parts of the algal body. From a physiological disease to an infectious disease, it will quickly spread to adjacent and even the entire body. In the breeding sea area, the growth and yield of Porphyra altar decreased.

Problems solved by technology

[0003] At present, the alternative methods to deal with the green algae and infected cells in the cultivated algae are net drying method and cold storage method. The traditional drying method is to dry the net curtain for several days in a row, dehydrate and dry the green algae and infected cells to dry and die , but the degree of drying is difficult to control. It is possible that all the green algae and infected cells die, or the death of green algae and infected cells is less. The net drying method is not only limited by the weather and tide, but also delays the growth of Porphyra altar for 3 to 5 days.

The cold storage method is to dry the altar seaweed net curtain in the shade, seal it and refrigerate it for a few days, and then put it into the sea for cultivation. Cold storage can kill most of the green algae and infected cells, but it is difficult to control the dry humidity of the seedling net, and it is easy to cause the altar laver to deteriorate if it is too wet. Drying will break the laver fronds and affect the further growth of laver; the cold storage method needs to untie the laver net curtain from the culture raft and tie it to the culture raft after treatment, which also requires a lot of labor in the process of processing and is easy to cause Problems such as partial shedding of seedlings
