Seedling cultivation technique of porphyra yezoensis planting technique of porphyra yezoensis

Illumination: light should be regulated in time, starting with 3000 lux, then decreasing to about 500 lux after forming sporangium branches. Temperature: when the temperature reaches 24 ℃, when porphyra yezoensis is inoculated from fruit spores to seedlings, the density of seedlings will be high in early inoculation, so it is necessary to reduce the light to restrain its growth. If the growth is slow, it is necessary to enhance the light in the nursery and increase the times of changing water to promote its rapid growth. Regulation: the late regulation time is from late August to early September.

Porphyra yezoensis belongs to the north, it can be eaten or used medicinally, and it is deeply loved by the majority of consumers. The demand for it is so high, so what is the breeding technology of porphyra yezoensis? Of course, the editor does not know, ah, has never seen ah, because the editor is a southerner, then let the editor to introduce to you the breeding techniques of porphyra yezoensis.

Seedling raising technique of porphyra yezoensis

1. The temperature and light intensity should be adjusted in time. At first, it was 3000 lux, then it began to drop after forming sporangium branches, and gradually decreased to about 500 lux. The temperature of Wynn reached 24 ℃, and the suitable growth stage of porphyra yezoensis was from fruit spore inoculation to seedling pond water. If the inoculation is early, the seedling will be dense and may grow too fast, so it is necessary to reduce the light intensity to inhibit the growth.

2. If porphyra yezoensis grows slowly, it is necessary to enhance the light of the seedling room and increase the times of changing water to promote the rapid growth of porphyra yezoensis. The regulation of porphyra yezoensis to the later stage is the time when a large number of expansion cells begin to form during the production from late August to early September.

Planting technique of porphyra yezoensis

1. Porphyra yezoensis likes the place where the tide is smooth, and there are fertile sea areas with certain winds and waves. It can live in sea water with a precision of 1.010 to 1.025. If porphyra yezoensis is lack of nitrogen fertilizer, the color of porphyra yezoensis is light and lustrous, and its leaves are slender. After the fruit spores are released, if they encounter a calcareous matrix that can protrude the germination tube, it will dissolve the limestone and drill into it and grow like a filament.

2. Thallus appeared in early winter and disappeared at the end of the next spring. Therefore, the leaf shape will adapt to the lower temperature. Porphyra haitanensis can grow at 0.5-18 ℃, while porphyra haitanensis is higher at the appropriate temperature. If the sea temperature exceeds 20 ℃, the leaves of porphyra will rot. Porphyra generally grows on the middle and high tide line and is a kind of red algae that loves light. Laver is very popular because of its delicious taste, good nutrition and special mushroom flavor.

After reading the above introduction, have you learned how to raise seedlings of porphyra yezoensis? The editor feels that it is still very difficult, and it seems that the cost of growing it is too high. It would be better to buy some to eat at home, saving time and effort. I wonder if the editor's information will help you.
