Nori (Pyropia yezoensis) seedling cultivation technology, nori planting technology

AbstractLight: light should be regulated in a timely manner, starting at 3000 lux, and later once conchocelis sporangial branches form, it should begin to be lowered, gradually reduced to about 500 lux. Temperature: after reaching 24°C, for Pyropia yezoensis from carpospore inoculation to seedling cultivation, early inoculation means high seedling density, so light should be reduced to inhibit growth; if growth is slow, the light in the seedling cultivation room should be increased and the number of water changes increased to promote rapid growth. Regulation: the later regulation period is from late August to early September.

Pyropia yezoensis is a northern species, and it can be eaten as well as used medicinally, so it is deeply loved by consumers. With demand for it so high, what then is the seedling cultivation technology for Pyropia yezoensis? Of course the editor does not know either, having never seen it, because the editor is from the south, so let the editor introduce the seedling cultivation technology for Pyropia yezoensis to everyone.

Nori (Pyropia yezoensis) seedling cultivation technology

1. Temperature and light intensity should be regulated in a timely manner, starting at 3000 lux, and later once conchocelis sporangial branches form, it should begin to be lowered, gradually reduced to about 500 lux. Temperature is very important at this stage of reaching 24°C; the suitable stage for Pyropia yezoensis growth is from carpospore inoculation to the seedling cultivation pond water. If inoculation is early, seedling collection density will be high, and growth may be too fast, so light intensity should be reduced to inhibit growth.

2. If Pyropia yezoensis grows slowly, the light in the seedling cultivation room should be increased and the number of water changes increased to promote rapid growth of Pyropia yezoensis. For the later regulation of the Pyropia yezoensis thallus: the time is from late August to early September, the period when swollen cells begin to form in large numbers during production.

Nori (Pyropia yezoensis) planting technology

1. Pyropia yezoensis likes places with smooth tidal flow, and also needs fertile sea areas with a certain amount of wind and waves; it can live in seawater with a precise specific gravity of 1.010-1.025. If it is in a sea area lacking nitrogen fertilizer, Pyropia yezoensis will be pale and lusterless, and its blades will be slender. After carpospores are released, if they encounter a calcareous substrate they can extend a germination tube, dissolve the calcareous material and drill into it, growing into a filamentous form.

2. The thallus appears in early winter and does not disappear until late spring of the following year. Therefore, the thallus adapts to relatively low temperatures. It can grow at 0.5-18°C; Pyropia haitanensis has a higher suitable temperature. If the seawater temperature in the sea area exceeds 20°C, the nori blades will rot. Nori generally grows at the mid-to-high tide line and is a light-loving red alga. Nori has a fresh taste, good nutrition, and a special mushroom-like aroma, making it very popular.

After reading the above introduction, has everyone learned the seedling cultivation technology for Pyropia yezoensis? The editor thinks it is still quite difficult, and growing it yourself seems too costly, so it is better to just buy some and eat it at home, saving time and effort. I wonder if the editor's information has helped everyone?
