Shearing is also known as hair, algae, hair, hair, fur, earband, cabbage, cuisine, purified pool hair, etc., for feeding with multicellular algae。
(i) origins and distribution. Vegetable is a low algae plant, widely distributed in the world, including canada, the united states, mexico, morocco, somalia, algeria, france, russia, mongolia, etc. Ningxia, gansu, inner mongolia, xinjiang, qinghai, shaanxi and hebei, to the north-west of china, are the most widely distributed。
Feeding in china has a long history and is well documented as early as khandai。
(ii) nutritional value and use. The nutritional value of vegetables is high: 200-234. 1 grams of protein, 570 grams of carbohydrates, 55. 9 grams of crude fat, 450 mg of phosphorus, 25. 6 grams of calcium and 2 grams of iron per kg of vegetables. It also contains, for example, sea choreone, blue algae chlorophyll, algae chlamydia and algae chlamydia。
I'm glad to hear it. In recent years, cooking has also become a popular rare dish on the mainland. The vegetables can be cooked, mixed, souped, smooth, soft, soft, soft and stylish, and can be a famous and valuable meal, with fresh and fine, soft and beautiful vegetables。
Vegetables have a high medicinal value, are flat, odourful, and have the effect of celibate and intestinal dysentery. Preventable detoxification, stuporosis, haemorrhagic and readily accessible urine can treat a wide range of diseases, such as diarrhea, dysentery, hypertension, bronchitis, nose bleeding and malnutrition。
Vegetables are sold best on the international market and are one of china's traditional export commodities. There is currently insufficient internal sales, and exports are even more inadequate。
(iii) characteristical characteristics。
Vegetable cells are filamentary, without a real cell core, and the primary mass in the middle is different from the surroundings, becoming a central body containing dyed particles. Vegetables are a filamentary form with irregular cylindrical or flat shapes, with no branch or two to three branches. The two ends of a fungus tend to expand into rods or slices, blunt circles, mults and interwoven themselves. When dry, the algae are dry and dry, dark black, such as hair. When the humidity is high, the algae inflate, glitter, blue green or brown. Vegetables can split themselves, typically 20-30 cm, with a small number of 40-50 cm, 0. 1 cm in diameter, 0. 2 cm in flat form and 0. 3-0. 4 cm in small size. The strain climbs into the wasteland, the grass, and is made up of solid and thick glacial glazing around parallel cells. Cells are in short cylinders or near circles with a diameter of 4-6 micrometres。
Vegetables are drought-resistant, hot, cold-resistant, infertile, highly adaptable and afraid of long-term water accumulation. The areas requiring average annual temperatures of 3-4°c are hardly distributed. It can withstand extreme temperatures of 38-39°c and extreme temperatures of 36°c. Vegetables are less demanding for soil and can be found in poor soil where higher plants cannot survive. Rocks and salines grow on the ground, and the growth and development of the bud requires more calcium, which is the soil condition for the growth and distribution of the vegetables。
Vegetables are at the lowest level in the plant community and can effectively use low light。
(iv) plantation techniques
The whole area is dry but grows well in a wet environment. It is therefore desirable to select permeable sand or alkaline soils. The soil is so fertile that it becomes flat, with a layer of sand。
2. Cultivate algae into a 3 cm fraction, with one end buried in the soil by approximately 0. 2 cm. Ensemble 200-300/m2. It may also be used to plant in a nest, i. E., at a density of 25-30 grammes per square metre, in a bag of 0. 1 to 0. 3 grams of dry vegetables. A layer of sand will follow。
3. Water is sprayed twice a day after management and harvesting and the air is humid. After 50 days of growth, it can increase by 2. 5 to 4. 5 times. When algae grow into blocks, they are harvested. Early spring and late autumn are harvest seasons in which harvests take place in the morning。
They can be rinsed, graded and tanned。
