What should we pay attention to when cultivating Porphyra hainanensis? What are the key points in cultivation?

1. Aquaculture sea area. The nutrients needed for the growth of Porphyra haitanensis are brought by the movement of seawater. Therefore, the best aquaculture sea area is an open or semi-open sandy and muddy bay with smooth tides, a flow rate of 15 to 30 cm/s, a tide level of 4 meters above the mid-tide to low tide, a nitrogen content of 100 to 200 mg/m3 in seawater, and no industrial waste is discharged into the aquaculture sea area.

2. Raft frame device. The raft frame is made of 14 bamboo poles, 21 buoys, 42 suspension ropes, 20 curtains, 2 floating ropes and 4 piles. The buoys are first fixed on the floating ropes on the shore. The buoys are arranged in parallel with a spacing of 4.8 meters. Then they are transported to the designated sea area and fixed on the front and rear 4 piles by tightening the cables. Then 7 poles are set on each side of the floating rope. Suspension ropes are tied to the upper part of the poles at equal distances. Each pair of poles supports 3 buoys, and curtains are set between the buoys.

3. Seedling collection. Choose an area in the middle tide zone where the dry tide can maintain dryness for 3 to 4 hours. The best time to collect seedlings is during the high tide period after the White Dew and before the Autumnal Equinox. Try to avoid the adverse effects of high temperature (above 27°C) on the attachment and germination of conchospores.

1. The density of seedling collection is determined by pouring spore water at sea, with 10 layers of strip curtains stacked together for seedling collection. 21 net curtains (5 meters × 4.8 meters) form a row, and the number of conchospores collected from one row of net curtains is generally 500 million to 700 million. The dyeing method can reduce the density by 1/3.

2. Seedling collection method: Transport the "shell seedlings" to the rapids in the evening, hang them on the side of the boat and immerse them 0.5 meters in the water for water stimulation; pull them into the boat before 6 am the next day, fill them with fresh and clean seawater to make shell spore water; at 11-13 noon (i.e. before and after the tide), sprinkle them evenly on the net curtain. If they are finished at 11 o'clock, add new seawater and sprinkle them again after 12 o'clock.

4. Management.

1. Seedlings can be seen 7 to 10 days after harvesting, and curtains can be divided after they are seen.

2. Daily management ① Check the safety of the curtain frame, and repair it in time if it is damaged. ② Adjust the drying time of the net curtain and expose it in time. After the conchospore seedlings are put into the sea, on the one hand, the seedlings are small and the density is low, and on the other hand, the net curtains are submerged in water for a long time, which is easy to grow diatoms and Enteromorpha, which will affect the emergence and growth of laver. Therefore, the method of drying curtains should be adopted to remove them. In addition, timely drying or drying curtains can effectively control the occurrence of laver diseases.

Pay attention to the breeding process, the breeding method, the sealing during the breeding process, and the breeding time. These breeding points are to pay attention to the air density during breeding, the sealing of oxygen, the sealing of the breeding tank, and whether the breeding process will be threatened by bacteria.

Pay attention to breeding techniques, water and fertilize in time, ensure soil fertility, do a good job of watering and irrigation, ensure air circulation, pay attention to air humidity and temperature, choose high-quality seeds, and kill insects and weeds.

Be sure to pay attention to the variety and the temperature. The temperature should be controlled between 23 and 27 degrees. The humidity should be kept at around 70%. To ensure the fertility of the soil, water and fertilize in time. Pay attention to pest control and weeding during the breeding process.

Is seaweed a hair-raising food?

1. Nori is cold in nature and is not an allergenic food.

2. The so-called "irritants" refer to certain foods that can aggravate diseases or induce disease attacks. Now it seems that some are related to allergic diseases, such as asthma and urticaria, and some are related to external symptoms such as sores, swellings and toxins. Hairtail, carp, eel, cockle, clam, crab, shrimp, sea cucumber among aquatic products; mutton, dog meat, donkey meat, horse meat among livestock meat; leeks, celery, coriander, fennel and other vegetables are all irritants.

3. Nori is sweet, salty and cold in nature. It enters the lung meridian and has the effects of resolving phlegm and softening hard masses, clearing away heat and promoting diuresis, and nourishing the kidney and heart. It is used for goiter, edema, chronic bronchitis, cough, goiter, gonorrhea, athlete's foot, hypertension, etc.

4. Generally, mainland hotels and households use the washed and soaked seaweed to make soup. In fact, there are many ways to eat seaweed, such as mixing it with cold dishes, stir-frying it, making stuffing, making meatballs, stir-frying it, using it as a side dish or main dish with eggs, meat, mushrooms, pea tips and carrots, etc.

5. It is best to eat 15 grams of laver each time. It is best to soak it in clean water before eating, and change the water once or twice to remove pollutants. Laver is cold in nature, so people with poor gastrointestinal digestion or abdominal pain should eat less.

6. If the laver turns blue-purple after being soaked in cold water, it means that the laver has been contaminated by toxic substances before drying and packaging. This laver is harmful to the human body and cannot be eaten.

7. Nori is a seafood product and is easy to get damp and spoil. It should be put into a black food bag and placed in a low temperature and dry place, or put in the refrigerator to maintain its taste and nutrition.

Additional information

Suitable for the crowd:

1. It is especially suitable for patients with goiter, edema, chronic bronchitis, cough, goiter, gonorrhea, athlete's foot, hypertension, early stage of lung disease, cardiovascular disease and various lumps and hyperplasia.

2. It is edible for general population.

Unsuitable crowd:

1. Laver is cold in nature, so people with weak spleen and stomach, abdominal pain and loose stools should avoid eating it; people with weak bodies should add some meat to reduce the coldness when eating it. Do not eat too much at a time to avoid abdominal distension and abdominal pain.

2. Do not eat too much. People with poor digestive function and spleen deficiency should eat less, as it may cause diarrhea. People with abdominal pain and loose stools should not eat it. Patients with lobular hyperplasia of the breast and various types of tumors should use it with caution. People with spleen and stomach deficiency should not eat it.

Laver is not a food that causes allergies. Laver is the algae of many wild laver species, such as Porphyra haitanensis, Porphyra yezoensis, Porphyra tongnanensis, and Porphyra gansu, of the algae family. The algae are purple and generally 12-30 cm high. The cultivated Porphyra haitanensis can grow up to more than 4 meters.

The so-called "fawu" is generally a term used in traditional Chinese medicine, referring to foods that are particularly likely to induce certain diseases (especially old diseases) or aggravate existing diseases.

Classification of irritants There are mainly the following categories of irritants that we come into contact with in our daily lives.

Edible fungi: mushrooms, shiitake mushrooms, etc., overeating can easily cause wind to rise in the yang, triggering chronic diseases such as liver yang headache, liver wind dizziness, etc. In addition, it can easily induce or aggravate skin sores and swelling.

Sea food: hairtail, yellow croaker, pomfret, clam meat, shrimp, crab and other aquatic products. Most of these foods are salty, cold and fishy. For people with allergies, they can easily induce allergic diseases such as asthma and urticaria. At the same time, they can also easily induce skin diseases such as sores, swelling and toxins.

Fruit categories: peaches, apricots, ginkgo, mangoes, bayberries, cherries, lychees, melons, etc. Predecessors pointed out that eating too many peaches can easily cause heat, carbuncles, sores, ulcers, boils, and worm-induced malnutrition, while eating too many apricots can cause carbuncles and boils.

Nori is not an allergy-inducing food. For most people, nori does not cause any disease. Of course, since nori grows in the sea, a small number of people are allergic to seafood and will experience allergic symptoms after eating nori, so these people should also pay attention to eating less or no nori.

Although seaweed is not an allergenic food, it is a cold food. If ordinary people consume it in large quantities, it may cause diarrhea. Therefore, people with poor digestion and spleen deficiency should consume it in small amounts. People with spleen and stomach deficiency, abdominal pain, and loose stools need to be even more cautious when eating it.

Additional information

Nori has high nutritional value and contains a variety of nutrients necessary for the human body. Its protein content is 9 times more than that of fresh mushrooms, and every 100 grams of nori contains 26.2 grams of protein.

It is also rich in vitamins A, B, B, C and trace elements such as iodine, calcium, and iron.

Its fat content is also 8 times more than kelp, 2 times more calcium than dried button mushrooms, 1 times more niacin than fungus, and nearly 10 times more riboflavin than shiitake mushrooms.

It is rich in nutrients and high in iodine. It can be used to treat "thyroid enlargement" caused by iodine deficiency. Nori has the function of softening and dispersing lumps, and is also useful for other stagnations.

It is rich in choline, calcium and iron, can enhance memory, treat anemia in women and children, and promote the growth and health of bones and teeth; it contains a certain amount of mannitol and can be used as a supplementary food for the treatment of edema.

Porphyra is the algae of many wild species of Porphyra haitanensis TJchang et BFZheng., Porphyra yezoensis Ueda., Porphyra suborbiculata Kjellm., Porphyra tenera Kjellm., etc. The algae is purple and generally 12-30 cm high. The cultivated Porphyra haitanensis can grow up to more than 4 meters.

The so-called "irritating foods" refer to foods that are particularly likely to induce certain diseases (especially old diseases) or aggravate existing diseases. The taboos on irritating foods are of great significance in both dietary health care and dietary therapy. Under normal circumstances, irritating foods are also foods, and eating them in moderation will not cause side effects or discomfort to most people. They will only induce the onset of certain special physical conditions and certain diseases related to them.

Foods that cause allergies, such as chicken, eggs, and pork heads, are foreign proteins to the human body, which can constitute allergens and cause illness. Fish, shrimp, and crabs contain histamine, which can increase vascular permeability, dilate capillaries, cause congestion, plasma exudation, edema, hypersecretion of glands, and increase in eosinophils, leading to allergic reactions in the body, i.e., allergic reactions, and induce skin diseases, such as erythema, papules, blisters, and fever. Some highly sensitive patients may even have allergic reactions to rice, wheat, and corn. Wine, onions, and garlic can directly cause dilation of skin capillaries and accelerated blood flow through alcohol or volatile irritants, aggravating or prolonging the original skin disease. Modern clinical studies have also confirmed that avoiding food that causes allergies is also important for reducing wound infection and promoting wound healing after surgery.

Classification of hair products

The scope of irritants is very wide. In our daily life, the foods that belong to irritants can be divided into the following categories according to their sources:

1. Edible fungi mainly include mushrooms, shiitake mushrooms, etc. Overeating of these foods can easily cause wind and yang, triggering chronic diseases such as liver yang headache, liver wind dizziness, etc. In addition, it can easily induce or aggravate skin sores and swelling.

2. Sea food mainly includes aquatic products such as hairtail, yellow croaker, pomfret, clam meat, shrimp, crab, etc. These foods are mostly salty, cold and fishy. For people with allergic constitution, they can easily induce allergic diseases such as asthma and urticaria. At the same time, they can also easily induce skin diseases such as sores, swelling and toxins.

3. Vegetables mainly include bamboo shoots, mustard greens, pumpkin, spinach, etc. These foods can easily induce skin sores and swelling.

4. The main fruit categories include peaches, apricots, ginkgo, mangoes, bayberries, cherries, lychees, melons, etc. Predecessors have pointed out that eating too many peaches can easily cause heat, carbuncle, sore, ulcer, furuncle, worm and other diseases; eating too many apricots can cause carbuncle and furuncle, and hurt the tendons and bones.

5. Poultry and livestock mainly include roosters, chicken heads, pork heads, goose meat, chicken wings, chicken feet, donkey meat, deer meat, beef, mutton, dog meat, goose eggs, duck eggs, etc. These foods are active and ascending in nature. Eating them can easily stir up wind and raise yang, triggering chronic diseases such as liver yang headache and liver wind dizziness. In addition, they can easily induce or aggravate skin sores and swelling. Although eggs are not considered to be irritating, it is not advisable to eat too many of them. Generally, no more than 2 eggs a day should be eaten, especially for patients with hepatitis, allergies, hyperlipidemia, high fever, kidney disease, and diarrhea. The reason is that eggs contain a lot of protein, but they are heterosexual proteins, and a considerable number of people have morbid reactions after eating heterosexual proteins.

In addition, vegetable oil, dregs, fermented rice, liquor, peas, soybeans, tofu, fermented tofu, silkworm pupae, onions, garlic, leeks, etc. are also considered as irritants. Sometimes, foods with meaty smells are also considered as irritants.

According to the performance of hair products, they are divided into six categories:

One is the food that causes fever, such as scallion, ginger, prickly ash, pepper, mutton, dog meat, etc.;

The second is wind-inducing things, such as shrimp, crab, goose, eggs, and toon buds;

The third is things that cause dampness and heat, such as maltose, glutinous rice, pork, etc.

Fourth, foods that induce cold, such as watermelon, pear, persimmon and other raw and cold foods;

The fifth is things that stimulate blood, such as chili pepper and pepper;

Sixth, foods that cause stagnant qi, such as mutton, lotus seeds, and water chestnuts.

Laver is not a hairy food. Laver is the algae of many wild laver species, such as Porphyra haitanensis, Porphyra yezoensis, Porphyra tongnanensis, and Porphyra gansu, of the algae family. The algae are purple, generally 12-30 cm high, and the cultivated Porphyra haitanensis can be up to 4 meters long.

The so-called "fawu" is generally a term used in traditional Chinese medicine, referring to foods that are particularly likely to induce certain diseases (especially old diseases) or aggravate existing diseases.
