Embodiment 1

[0040] This embodiment discloses a prevention and treatment method of Porphyra zebra shell filament macular disease prevention and treatment agent, and the prevention and treatment method includes the following steps:

[0041] Step S1, modulating the pH value of the soaking solution;

[0042] Step S2, soaking the shell filaments in S1 soaking solution;

[0043] Step S3, setting the interval time, and repeating the soaking step of S2 for many times.

[0044] In the step S1, the soaking solution is prepared, and the pH range of the filamentous soaking solution is determined to be 5.0;

[0045] The step S2, the specific steps of the step S2 are as follows,

[0046]S21: Divide the shell filaments in the nursery pond into 1-5 groups and soak them in the soaking solution. In this embodiment, the shell filaments are divided into 5 groups, so that multiple time points can exist in this design, and more comprehensive observation can be made Survival of shell filaments at various tim...

Embodiment 2

[0052] The difference between this embodiment and the first embodiment is that the soaking solution is prepared, and the pH range of the filamentous soaking solution is determined to be 5.5.

Embodiment 3

[0054] The difference between this embodiment and the first and second embodiments is that the soaking solution is prepared, and the pH range of the filamentous soaking solution is determined to be 6.2;

[0055] Determination of laver filament survival rate and macular bacterium survival rate by embodiment 1, embodiment 2 and embodiment 3, obtain following table 1:

[0056] Table 1

[0057]

[0058] According to Table 1, it can be seen that the survival time of the shell filaments in the pH5.0 soaking solution is the least, and the shell filaments all die after the soaking time exceeds 15 minutes; Within 20 minutes, the survival rate of shell filaments in the pH6.2 soaking solution can reach 90%; therefore, the greater the acidity of the soaking solution, the longer the survival time of the filaments is. At the same time, the survival time of maculobacteriaceae was also shortened, but in terms of the degree of influence on the conch filamentous plants, the degree of damage...

Abstract

The invention provides a method for preventing and treating yellow leaf blotch of shell conchocelis of porphyra yezoensis and a culture apparatus. The method comprises the following steps: step S1, regulating pH value of soaking liquid; step S2, soaking the shell conchocelis in the soaking liquid obtained in the step S1; and step S3, setting interval time, and repeating soaking operation in the step S2. The culture device comprises a culture box, wherein a culture unit is arranged on the top of the culture box; the culture unit is divided into three culture media along a box body in the transverse direction; and the compositions and the structures of the culture media are the same. The method has the beneficial effects that the time of treatment on the shell conchocelis of the porphyra yezoensis can be shortened by acid treatment, the efficiency is improved, and meanwhile, costs can be reduced; and by the culture apparatus, the step of liquid drainage after culture can be simplified, meanwhile, culture time is monitored automatically, and the circumstance that the accuracy of a test result is affected due to deviation of time factor in a culture process is avoided.

Description

technical field [0001] The invention relates to the technical field of prevention and treatment, in particular to a method and a cultivation device for the prevention and treatment of Porphyra zebra shell filament macular disease. Background technique [0002] The macular disease of Porphyra variegata was first seen in June, and during the hot summer season in July and August, some pinhead-sized yellow spots appeared on the edge of shell filaments at the beginning of the disease, and then gradually expanded to form lesion spots of various sizes , with the expansion of the lesion, the color of the filaments also gradually changes from yellow to white, and the junction of the healthy part and the lesion is slightly reddish brown. The disease is highly contagious and can infect all shells within a few days. [0003] In the Chinese literature "Prevention and Control Technology of Porphyra zebra macula" ("Aquaculture" 1995 No. 3) and the Chinese literature "Diseases and Preventi...
