In ordinary times, surely some friends wonder what is the difference between pineapple and pineapple? The following practical information column I organize the difference between pineapple and pineapple for you, for your reference, I hope to help you, more detailed content please click to view.

Pineapple

Pineapple (Ananas comosus) is commonly known as pineapple, is one of the famous tropical fruits. Fujian and Taiwan called Wang Li or Wang Lai (?ng-l?i), the New Malaysia area called Huang Li, the mainland and Hong Kong called pineapple. There are more than 70 varieties, one of the four famous fruits of Lingnan. Pineapple is native to South America, Brazil, Paraguay, along the Amazon River Basin, the 16th century from Brazil to China. It has now spread throughout the tropics. Its edible part mainly consists of fleshy enlarged inflorescence axis, spirally arranged in the periphery of the flowers, flowers usually do not bear fruit, the persistent perianth lobes surrounded by a cavity, the cavity hides the atrophied stamens and styles. The fibers of the leaves are very tough and can be used for fabrics, rope making, netting and papermaking.

Stem short. Leaves numerous, rosely arranged, sword-shaped, 40-90 cm long, 4-7 cm wide, apically acuminate, entire or sharply toothed, green ventrally, pinkish-green dorsally, often tawny at the margins and tips, the leaves at the top of the inflorescence becoming smaller and often reddish.

Inflorescences arising from leafy clusters, pine-ball-like, 6-8 cm long, enlarged when fruiting; bracts green at the base, reddish in the upper half, triangular-ovate; sepals broadly ovate, fleshy, reddish at the top, ca. 1 cm; petals long elliptic, pointed at the tip, ca. 2 cm long, purplish-red in the upper part, white in the lower part.

Polyanthus fruit fleshy, more than 15 cm long. Flowering period summer to winter.

The pineapple has its own special growth habit. Most pineapples have a rosette of leaves. The base of the leaf clusters forms a leaf cylinder that holds water. This kind of pineapple growth and development of water, not stored in the leaf flesh, but stored in the cluster of leaf clusters in the center of the growth point of the natural formation of the groove (that is, the unique rosette leaf tube) growing season in addition to the need for frequent watering to keep the pot moist, but also must be often to the leaf tube watering, so that the leaf tube is stored with sufficient water so that it can thrive, this is a special habit of pineapple.

The vast majority of ornamental pineapple another special habit is to bloom only once in a lifetime, after the flowering of the mother plant and then live for a period of time that is dead, this time in the mother plant at the base of the stem or root sprouted one to several tillers (niè) buds, these tillers are propagation of new plants good material.

Temperature

Pineapple is native to the tropical high temperature and arid regions of South America, love warmth, in the average annual 24-27 (growth is optimal, 15-40 ℃ range can grow, 15 ℃ below the growth of slow, 10 ℃ below the basic stop growing, 5 ℃ is the critical temperature of cold damage.

Planting depth is generally no more than 1/5 of the bud length is appropriate. After insertion, put in the shade, keep the potting soil dry. In the temperature of 22 ~ 24 ℃ after about 1 month will be able to root. Root growth temperature of 29-31 ℃, below 5 ℃ or higher than 43 ℃ that is, stop growing; root growth began in March, and with the rise in temperature and rapid growth. late May to July growth peaked in October and tend to slow down, December to the following year in February near the surface of the root system due to cold and drought and death. Warm spring leaves began to draw, May-July leaf color green, faster growth, winter basically stopped drawing, leaf color reddish-yellow, such as cold damage to the leaf tissue dehydration regression green, will dry up.

Moisture

Strong drought tolerance, but growth and development still require a certain amount of water, in the annual rainfall of 500-2800mm can grow in the region, and to 1000-1500mm and uniformly distributed as the most suitable, China's producing areas of the annual rainfall is more than 1,000mm, but also more concentrated in the growth of April-August. Basically meet the water requirements.

Soil water shortage pineapple plants have the function of self-regulation, reduce transpiration intensity, slow down the respiration, saving the leaf storage water to maintain life activities; severe water shortage, the leaf is reddish-yellow, must be irrigated in a timely manner in order to prevent drying out; too much rain, soil humidity, will make the root system rot, the emergence of the heart of the plant rot or withering. Therefore, heavy rain or heavy rain must be timely drainage.

Light

Pineapple originally grew in the semi-shaded tropical rainforest, more shade-tolerant, due to the long-term artificial cultivation of domestication and increased light requirements, adequate light growth, high fruit sugar content, good quality; insufficient light growth is slow, high fruit acid content, poor quality. Light to reduce 20%, yield decreased by 10%. But too much light, coupled with high temperatures, the leaves become reddish-yellow, the fruit is also easy to burn.

Soil

Pineapple has a wide adaptability to the soil, because the root system is shallow and good gas, so the loose, well-drained, organic matter-rich, pH 5-5.5 sandy loam or mountain red soil is better, barren, sticky, poorly drained soil and a high water table are not conducive to pineapple growth.

Wind

Pineapple dwarf, the direct impact of wind damage is relatively small, the wind below level 3 is also conducive to respiration. Strong typhoons and gales can also blow down plants, break fruit stalks and twist leaves, affecting normal growth and development; cold winds and cold rains in winter can cause heart rot.

Pineapple is flat, sweet, slightly acidic, slightly astringent, slightly cold, with a summer thirst, digestion and diarrhea, spleen and stomach, solid energy, beneficial blood, digestion, dampness, skinny and other effects, for the summer medical food and excellent seasonal fruits, but should not eat too much at a time. (Li Shizhen, "Compendium of Materia Medica")

Pineapple contains a substance called "pineapple prion enzyme", which breaks down proteins, aids in digestion, dissolves fibrin and blood clots blocked in the tissues, improves local circulation, dilutes blood lipids, eliminates inflammation and edema, and can promote blood circulation. Especially after eating meat and greasy food, eating some pineapple is more appropriate, can prevent fat deposition.

Bromelain can effectively break down the protein in food and increase gastrointestinal motility. This enzyme in the stomach can break down protein, supplement the body's digestive enzyme deficiency, so that patients with indigestion to restore normal digestive function. This substance can prevent gel aggregation and can be used to make milk sour or soften other fruits, but this feature will be weakened in cooking.

In addition, the sugar and enzymes contained in pineapple have a diuretic effect, which is beneficial to people with nephritis and hypertension, and also has a secondary effect on bronchitis. Due to the role of fiber, the treatment of constipation also has a certain efficacy. When there is indigestion, eat some pineapple can open the stomach and smooth gas, relieve grease, can play a role in digestion, but also can relieve constipation. In addition, pineapple is rich in vitamin B1, can promote metabolism, eliminate fatigue.

Pineapple juice has a cooling effect, and can effectively prevent bronchitis, but fever is best not to eat. After medical research, since ancient times, human beings have often relied on the pineapple contains bromelain to ease the symptoms of sore throat and cough. Pineapple skin is rich in pineapple enzyme, has rich medicinal value, according to foreign experts for more than 20 years of experiments, long-term consumption of pineapple skin, cardiovascular, diabetes incidence significantly reduced, and has a certain anti-cancer effect. It also contains an enzyme that can break down proteins.

Eating Value

Pineapple as a fresh food, golden flesh, rich flavor, sweet and sour taste, crisp and juicy. Pineapple fruit in addition to fresh food, more canned, because it can maintain the original flavor and widely loved. Processed products canned pineapple is known as "international canned fruit", can also be made into a variety of processed products, widely welcomed by consumers.

Pineapple, like some fruits, will make some people allergic to eat, allergic reactions can occur as soon as 15 minutes, such symptoms are called "pineapple disease" or "pineapple poisoning". For example, abdominal pain, diarrhea, vomiting, headache, dizziness, skin flushing, itching, limbs and tongue numbness, allergy is more serious, but also appeared in respiratory distress, shock and other reactions.

The pineapple soaked in salt water and then eat, but also part of the organic acid contained in the decomposition of the salt water, remove the acidic flavor, so that the pineapple tastes more sweet. You can also put it in boiling water and cook it before eating. Bromelain in 45 ℃ ~ 50 ℃ began to denature, to 100 ℃ when more than 90% are destroyed; glycosides can also be destroyed at the same time to eliminate; 5-hydroxytryptamine is dissolved in water. After boiling the taste is also improved. Each time you eat pineapple can not be too much, overdose is harmful to the stomach and intestines. The first time you eat the baby only eat a cookie-sized piece, if there is no abnormality, the next time you can increase the amount appropriately.

Eating taboos

1, because the pineapple contains stimulating effect of glycosides and pineapple protease, it will break down the body's proteins, and it is on the people's oral mucosa and the lips of the tender epidermis has a stimulating effect, if you eat a pineapple before soaking in salt water, it will give a person a paralyzing feeling of pain. Therefore, the peel and fruit thorns should be trimmed, cut the pulp into pieces, in dilute salt water or sugar water maceration, leaching glycosides, and then eat, soak pineapple in salt water, can effectively destroy the "pineapple prion enzyme" within the structure of the allergy-causing, and thus lose the ability to cause allergies, and the loss of toxicity for some body.

2, after eating meat or greasy food, eat some pineapple is very good for the body, "pineapple old meat", "pineapple beef" are safe to eat dishes.

3, pineapple and eggs can not be eaten together, the protein in the egg and pineapple in the combination of fruit acids, easy to make protein coagulation, affecting the digestion.

4, pineapple and honey can be eaten at the same time, and pineapple and honey decoction water service can cure bronchitis. But for people who are unwell or have diarrhea symptoms, it is recommended not to consume this way.

Pineapple

Pineapple (Ananas comosus), pineapple family, pineapple genus. Native to Brazil, Argentina. The south of China can be cultivated in the open ground for the production of fruit or ornamental.

(a) Morphological features: perennial evergreen plants. Leaves are clustered, rosulate, sword-shaped, slightly concave above, with fine spines on the edge, gray-green. Inflorescences terminal, bracts green, flowers blue-purple. The fruit is fleshy, sweet and flavorful, and is a famous fruit.

Its horticultural ornamental varieties are showy pineapple (A.C. 'Variegatus'), also known as spotted-leaf pineapple, colorful pineapple, gilt-edged pineapple, is edible pineapple, commonly known as pineapple. The colorful pineapple has 30 to 50 leaves, about 50 centimeters long and 3 centimeters wide. Leaf adaxial green, abaxial gray-green, edge with creamy yellow and light red stripes, inflorescence ovoid, that is, with red fruit - pineapple (pineapple).

(ii) Habitat: prefer warm, humid and sunny environment. Prefer loose, good permeability, well-drained, slightly acidic soil.

(3) Cultivation and management: the appropriate temperature in summer is 25-30 ℃, the appropriate temperature in winter is 15-18 ℃, the lowest temperature can not be lower than 12 ℃. When the temperature is high, the plant can be sprayed with water. Soft sunlight makes the leaves more beautiful.

During the growing season, you can water the plant a lot while filling some water in the rosette leaf tube. After each watering, water a second time when the potting soil is drier, not too much. In winter, the potting soil should be slightly dry.

May to September growth period, every two weeks to fertilize. In addition to this, additional phosphorus and potassium fertilizer should be applied twice.

Every year between March and April to change the pot. In addition to the requirement of humus-rich, fertile potting medium, it is more important to loose, good permeability, good drainage, slightly acidic soil. Can buy a good mix of cultivation medium, but also according to the following formula into a well-mixed potting soil: rotting leaf soil (or peat soil) 1/2 ~ 3/4, river sand (should not be too fine) 1/4 ~ 1/2, and mixed with 3% to 5% of the rotting chicken manure, cake fertilizer and other high-quality organic fertilizers and bone meal, and so on.

(d) reproduction: can be used tiller or top bud reproduction. Tiller reproduction can be carried out in the spring when the pot, the mother plant dug out, with a sharp knife to cut off the mother plant on both sides of the tiller plant, the incision should be flat, and then planted in the sand, soil half of the small pots, to maintain a moist and 25 ℃ or so of the temperature, can be rooted and leaves. This propagation method is commonly used. Top bud propagation, that is, the top of the fruit leaf clusters cut off, cuttings in the sand bed, to be rooted and transplanted. Before planting, the cuttings should be air-dried for a few days to avoid rotting, the temperature is maintained at about 25 ℃, 1 month to root.

(E) pests and diseases: generally few pests and diseases. There are leaf blight and brown spot disease damage, the onset of the disease, with 25% carbendazim 1000 times liquid spray control. If there is shellfish damage, should be in the larval hatching period, with 80% dichlorvos emulsion 1000 times liquid spray.

(F) Application: Because of the verdant leaves, inflorescences, potted plants displayed in the hall, window sill, etc. for ornamental purposes, is a dual-purpose plants, flowers and foliage.

Pineapple taste sweet, slightly acidic, flat, into the stomach, kidney meridian;

With thirst quenching and quenching, spleen and thirst, swelling, eliminating dampness, sobering up and benefiting from the efficacy;

Can be used for dyspepsia, intestinal inflammation and diarrhea, summer fever, body heat and thirst and other conditions, but also can be used for high blood pressure, dizziness, hand and foot weakness adjuvant therapy.

Difference between pineapple and pineapple

Pineapple itself has no bitter flavor, unlike pineapple, we eat pineapple before to use salt water to soak, pineapple does not have to go through so much trouble, directly eat can be.

Eating pineapple we can directly use our hands to pluck the skin to eat, eat pineapple to use a special knife to peel off the skin to eat.

The skin of pineapple is soft and can be rubbed by hand. The skin of pineapple, on the other hand, is solid and cannot be touched by hand.

The top side of the skin of pineapple is not prickly and has no thorns, while pineapple has prickly thorns.

Generally speaking, pineapples are bigger.

1 Nutrition is similar.

The protease in pineapple and pineapple can effectively break down proteins, which helps the peristalsis of the stomach and intestines, promotes digestion, and improves the blood circulation of the organism; rich in vitamin B on the nourishment of the skin, moisturize the hair, and alleviate the body's nervousness and fatigue are of great help. People often eat pineapple to relieve sore throats, a cup of fresh pineapple juice or pineapple juice, have the effect of preventing bronchitis.

2 belong to the same pineapple family, but the origin is different .

Pineapple and pineapple belong to the same pineapple family, from the biological point of view, there is no big difference between the two, you can say that pineapple is pineapple. But different places of origin, the difference in climate environment makes them in the form, flavor and texture and so on has some not easy to notice the difference, from the market point of view, pineapple is pineapple, pineapple is pineapple, these two are different fruits.

3 with or without thorns

Pineapple thorns are very shallow, peeled, can be eaten directly: but the pineapple is different, peeled also need to remove the inner thorns, which is why we usually buy pineapple has a channel groove, a small hole. This is why we usually buy pineapples with a groove, a small hole. So eaters, be sure to keep your eyes open, some unscrupulous businessmen will remove the thorns of the pineapple so that you think it is a pineapple oh.

4 price difference

Probably nature's favor, the same belongs to a fruit of pineapple and pineapple, just because the production of pineapple than the pineapple a little less, its price than the pineapple expensive some of them.

5 shape is not the same

Pineapple and pineapple leaves are the tip of the tip of the sword shape, but the difference is that the edge of the pineapple's leaves are serrated, pineapple is not. There is also a difference in the skin of the two, with the pineapple skin being yellowish-orange and the pineapple skin being green.

6 taste different

Pineapple ripe will have a light fragrance, taste sweet but not greasy, soft flesh texture, especially juicy, pineapple is the opposite, its taste is sweet and greasy sweet and greasy, and the fragrance is very strong, eat too much tongue will have a numbness and tingling, and even cause allergic reactions, soak with salted water and eat a better taste; Pineapple can be eaten directly, will not occur.
