Where is pineapple suitable for planting

1, pineapple is suitable for planting in tropical and subtropical areas.

There are about 61 countries and regions in the world where it is cultivated. In addition to China, Thailand, the United States, Brazil, Mexico, the Philippines and Malaysia and other cultivated more.

China's pineapple cultivation is mainly concentrated in Taiwan, Guangdong, Guangxi, Fujian, Hainan and other provinces, Yunnan, southern Guizhou also has a small amount of cultivation, has a history of more than 400 years. The main production areas of pineapple in Taiwan are Tainan, Taichung and Kaohsiung. Pineapple cultivation area in Guangdong Province is larger, with more production, and the production area is concentrated in Shantou, Zhanjiang, Jiangmen and other areas and the suburbs of Guangzhou. The main production areas in Guangxi are Nanning, Wuming, Yongning, Ningming, Bobai and other counties and cities.

2, pineapple suitable for the growth of the environmental zone:

(1) temperature:

Pineapple is native to the tropical high temperature and arid areas of South America, like warm, in the average annual 24-27 (the growth of the most suitable, 15-40 ℃ range are able to grow, 15 ℃ below the growth of slow growth, 10 ℃ below the basic stop growing, 5 ℃ is the critical temperature of the 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 ℃ about 1 month after the root can be born. Root growth temperature for 29-31 ℃, below 5 ℃ or higher than 43 ℃ that is, stop growing; root growth began in March, and with the increase in temperature and rapid growth. late May to July growth peaked in October and tend to slow down, December to the following year, 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 green, will dry up.

(2) moisture:

Strong drought tolerance, but growth and development still need a certain amount of water, in the annual rainfall of 500-2800mm can grow in the region, and to 1000-1500mm and the distribution of uniform for 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 to meet the requirements of the water. Soil water shortage pineapple plant has its own regulation function, reduce transpiration intensity, slow down the respiration, saving water stored in the leaf, in order 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 plant heart rot or withering. Therefore, heavy rain or heavy rain must be timely drainage.

(3) light:

Pineapple original growth in the semi-shaded tropical rainforest, more shade-tolerant, due to long-term artificial cultivation and domestication and increased light requirements, sufficient light under good growth, high fruit sugar content, good quality; insufficient light is slow growth, high fruit acidity, poor quality. Light reduces 20%, yield drops 10%. But too much light, coupled with high temperatures, the leaves become reddish-yellow, the fruit is also easy to burn.

(4) Soil:

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

(5) wind:

Pineapple dwarf, wind damage direct impact is 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 wind and rain in winter can cause heart rot.

In summary, pineapple is suitable for planting in tropical and subtropical areas.

Expanded Information:

p>1, the nutritional value of pineapple:

Pineapple fruit quality, nutritious, contains a large amount of fructose, glucose, vitamin B, C, phosphorus, citric acid and protease and other substances. Each 100 grams of pineapple contains 87.1 grams of water, 0.5 grams of protein, 0.1 grams of fat, 1.2 grams of fiber, 0.1 milligrams of nicotinic acid, potassium 126 milligrams of sodium 1.2 milligrams of zinc 0.08 milligrams of zinc, 8.5 grams of carbohydrates, calcium 20 milligrams of phosphorus 6 milligrams of iron 0.2 milligrams of carotenoids 0.08 milligrams of thiamine 0.03 milligrams, riboflavin 0.02 milligrams of. Vitamin C8~30 mg, ash 0.3 g, and also contains a variety of organic acids and pineapple enzymes.

(2) Nutritional content:

Each 100 grams of pineapple contains 48 calories. Specific nutrient content is detailed in the following table:

2, pineapple food 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.

Soak the pineapple in salt water and then eat it, but also make part of the organic acid contained in the decomposition of the salt water, remove the acidic flavor, so that the pineapple tastes sweeter. 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. The flavor is also improved after boiling. Each time you eat pineapple should not be too much, excessive consumption is harmful to the stomach and intestines. First time to eat the baby only eat a cookie-sized piece, if there is no abnormality, the next time can be appropriate to increase the amount.

3, pineapple food 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 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 kind of paralysis and tingling sensation. 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 allergic to the person, and loss of toxicity for some of the physique.

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