Planting durian durian stinks, is it good for your health?

The aroma components of fruits include hydrogen sulfide, Ethyl hydrogen disulfide, dialkyl polysulfide, ethyl acetate, 1, 1 diethoxyethane (1, 1- diethoxyethane) and ethyl -2- methyl butyrate (eth).

The fatty acids of fruits (including peel, pulp and seeds) are palmitic acid, arachidic acid and palmitic acid. Durian is the most famous in Thailand and is known as the "king of fruit".

Its smell is very strong, people who love it praise its smell, and people who hate it complain about its smell. So hotels, trains, planes and public places are not allowed to be brought in. Thai people especially like durian and are often attracted by its special fragrance. The popular proverbs in Thailand, such as "Wear a sarong, buy a durian, and have an empty suitcase" and "Eat durian as a wife", show how much Thai people like durian.

Yu Dafu, a China writer, wrote in Travel Notes of Nanyang that durian smells like rotten cheese mixed with onions and turpentine, which is really smelly, fragrant and delicious. However, people who have never eaten durian will make you want to eat more and more as long as they try the first bite boldly. Many tourists will have endless aftertaste and even become addicted after tasting the delicious durian, so now Thai durian is sold all over the world, especially in Hongkong, Taiwan Province Province, Japan, Europe and America, and now it is also sold to China.

Durian is oval, generally weighing about 2 kilograms, with a wooden hard shell outside and a room inside. Every room has three or four seeds as big as egg yolk, with ten to fifteen. The seeds are covered with a layer of ointment, that is, pulp, milky yellow. It tastes sweet and fragrant.

Precious varieties of durian cost three or four hundred baht each, and the average variety costs about one hundred baht. You can know the advantages and disadvantages of durian from the epidermis. The cone-shaped thorns are thick and sparse, generally well developed, with many fruits and thick and delicate pulp. If the thorns are thin and dense, the fruit and pulp are thin and the meat is thick.

Durian has high nutritional value. Besides high sugar content, it also contains starch 1 1%, sugar 13%, protein 3%, vitamins, fat, calcium, iron and phosphorus. Durian is a hot fruit, and drinking is forbidden within nine hours after eating durian.

Durian is full of treasures. Stones can be boiled and baked. It tastes like a half-cooked sweet potato. Cooked durian water can treat sensitive skin sores and itching. Durian shells and other chemicals can be synthesized into soap, and can also be used as medicinal materials for skin diseases.

Durian is a woody persimmon plant and the tallest fruit tree in tropical areas, with a trunk as high as 25 to 40 meters. A tree can produce eighty durians every year.

Durian will ripen ten days after it is picked from the tree. There are 200 varieties of durian in Thailand, and 60 to 80 kinds are widely planted at present.

Among them, there are three most famous species: the light species are monochloro, Jiaoluntong, Harufuji, Jinzhen and Chani, which bear fruit after four or five years; Medium-sized species have long stems and long valleys, and bear fruit in six to eight years; The re-planting is Kampong and Ina, and the result is eight years. They bear fruit once a year, and the maturity time is one or two months apart.

Among them, people are familiar with (1) "Golden Pillow" and (Meng Tong), which are the most popular ones at present. The meat is rich and sweet, and the flesh is golden yellow. Often one of the petals is large, called "main meat", because the smell is not too strong, so it is very suitable for beginners to "get started" eating this smelly and fragrant fruit. Nowadays, gold pillows can be eaten all year round, but the price varies with the season. The price is the cheapest and the peak season is the best. (2) "Shani" has a small leaf, a small head, a lot of meat, a small core, a cheaper price than a golden pillow, and dark yellow flesh. (3) Long stalk: It is named because the stalk of this durian is longer than other varieties. This variety has a long and round handle, and the whole durian is mainly round. The pulp and stone are also round, with green skin, dense thorns, large stone, small and delicate pulp and strong fragrance; (4) Ancient Ye Tao: The meat quality is particularly delicate, sweet as dense, and the core tip is small. It is welcomed by "foodies" and is the most expensive durian.

Durian in Thailand has a wide range of producing areas, ranging from warm Li Wu in the central part to Luo Yong in the mobile part. Durian from Bazhen Li Wu won the championship. Durian in southern Thailand is not as good as durian in central and eastern Thailand. However, due to the late maturity, other durian seasons are "scarce".

Buying durian is also a kind of learning. Whether a durian is delicious or not is not only related to the variety, origin, climate, fertilization and picking time, but also important to cut it in time.

Durian meat is hard and light. It tastes like chewing wax and won't taste good. So when buying, you may wish to consult the manufacturer. They will tap durian with a small bamboo stick to identify its maturity, and at the same time decide whether it can be cut open by smelling, or you can choose fruit stalls or supermarkets that have cut their skins and only sell meat, so that you can press them with your naked eyes and fingers to see and feel whether they are mature or not. At the same time, a person can't eat a durian at a time, so it's a good idea to buy some at a time.

There are two theories about the origin of durian in Thailand. One originated in Malaysia and was introduced to Thailand during the Dacheng Dynasty. Malaysians call durian "local food", Thai still calls it this way, and Chinese translates it as "durian".

Another way of saying it was introduced from Tahuai, Mali and naoshi in Myanmar. There are also two legends about this. One is 1787. When the Siamese army attacked Myanmar, it tried to seize his arms, but failed to conquer it.

During the siege. Due to the difficulty in transportation and the lack of food and grass in the army, the generals had to order their soldiers to look around for wild fruits to satisfy their hunger. The soldiers found a huge prickly fruit durian in the forest.

When they tried to cut it open, it was unexpectedly sweet and delicious. Later, when going back and forth to Bangkok, many officers and men took durian stones with them and planted them around their houses.

It is said that durian trees have been growing in the yard of the descendants of officers and men who have been to Myanmar before Bangkok for 100 to 150 years. Due to the two floods in 187 1 year and 1942, these durian trees became extinct. The second type was introduced into southern Thailand by merchant ships between Thailand and Myanmar, and later spread from Surat Thani to Bangkok and other places.

≮ Efficacy ≯ Durian is rich in protein and lipids, which has a good nourishing effect on the body and is a good source of nutrition for fruits. Durian has a special smell, and different people feel different. Some people think it stinks like cat shit, others think it stinks.

Can durian seeds be planted?

It is suggested that when the temperature is 25℃ in spring, it is best to disinfect the substrate in advance (strong light irradiation, watering with potassium permanganate or carbendazim solution, drying in the air, or microwave 10 minute), and the substrate should be loose, preferably sandy nutrient soil. Because the seeds are relatively large, the planting spacing is 20 cm, and the seed covering thickness is 1~2 cm. Then put it in a well-lit place, cover it with transparent glass or plastic film, keep it warm and humid, and pay attention to ventilation when the temperature reaches 30℃ to avoid high temperature injury to seedlings. Pay attention to keep the substrate moist and never dry. Just find a clay pot and bury the mature seeds after eating. In Guangdong, you can see the appearance in about a month. If you want to see fruit, there is no chance without a big garden. You can go to south china botanical garden. .

What are the conditions for planting durian?

Planting conditions:

Durian is a pure tropical crop. Generally, tropical crops require higher heat conditions, and can grow normally in areas with annual absolute low temperature above 0℃, basically frost-free all year round, accumulated temperature ≥ 10℃ and annual precipitation ≥1000 mm. ..

Durian, which originated in the tropics or has been planted for a long time, can only bear fruit normally in a year with suitable heat and climate conditions. According to reports, Hainan Xinglong Tropical Botanical Garden has successfully cultivated durian. Durian is a big tree, with a height of 15-20m, obvious trunk and fragile branches, which are easily affected by strong winds. Durian usually blooms in April-May and matures in August-September.

1. Planting

Durian can be sown every year, especially in spring. The suitable row spacing of sowing plants is 20cm × 20cm. In the seedling growth period, attention should be paid to weeding and fertilization to promote seedling growth. Excellent mother plants can be propagated by air layering, which is easy to take root. It only takes 60-70 days from branch circle to seedling.

2. Seedling colonization

Seedlings can be planted when the height is 30-40 cm, the row spacing is 3m×5m, and organic fertilizer, soil miscellaneous fertilizer and appropriate amount of lime are applied as base fertilizer. It can be planted all year round, especially with soil.

3. Fertilization management

Durian trees should be fertilized/kloc-0 times a year, that is, spring budding fertilizer, summer fruit swelling fertilizer and pre-harvest fertilizer, especially fruit swelling fertilizer. Deep application of organic fertilizer after fruit harvesting.

Step 4: plastic trimming

Due to the strong germination ability of durian tree, attention should be paid to shaping after planting 1-2 years, and the fruit should be pruned in time after picking to maintain a good tree shape.

Step 5: Harvest the fruit.

When the durian fruit turns orange-yellow or orange-red, it is ripe and can be harvested. The fruit can't be eaten directly after harvest, and it takes 4-7 days to mature, and it is expected that the pulp will soften before eating.

Because durian can only grow and bear fruit in the climate with high temperature all the year round, even in the equatorial region, the highland above 600m above sea level can not grow durian or bear fruit because of the temperature drop.

Extended data:

Durian is one of the famous tropical fruits, which is native to Malaysia. Some countries in Southeast Asia have more crops, among which Thailand has the most. China, Guangdong and Hainan are also planted.

Durian is the most famous in Thailand and is known as the "king of fruit". Its smell is strong, people who love it praise its smell, and people who hate it complain about its smell.

Legend has it that during the Ming Dynasty in ancient China, when the long-distance fleet arrived in Southeast Asia today and tasted the local specialty fruit, Zheng He praised it greatly. But this kind of fruit can only be harvested once a year, so it is named nostalgia, and later generations take its homonym, called durian.

There are two theories. One originated in Malaysia and was introduced to Thailand during the Dacheng Dynasty. In Malay, durian is called "Tuliang", while in Thai, it has always been called "durian".

Another way of saying it was introduced from Tahuai, Mali and naoshi in Myanmar. There are also two legends about this. One is 1787.

Planting height

It can be planted when it is 30~40 cm, with a row spacing of 3m×5m, and base fertilizer, soil miscellaneous fertilizer and appropriate amount of lime are applied as base fertilizer. It can be planted all year round, and it is best to bring native seeds.

Fertilization management

Results Fertilization should be applied 1 time every year, that is, spring budding fertilizer, summer fruit swelling fertilizer and pre-harvest fertilizer, especially fruit swelling fertilizer. Deep application of organic fertilizer after fruit harvesting.

Plastic trimming

Because of its strong germination ability, attention should be paid to shaping after planting 1~2 years, and the fruit should be pruned in time after picking to maintain a good tree shape.

Can durian grow in potted plants?

The leftover durian seeds can be planted, but because durian is a tropical fruit, its locality is strict. If it is not planted in the tropical area, it may not bear fruit in the future.

The planting method is as follows:

Eat the pulp first, leave the stone, soak it in water for a few days, and find a shallow pot to bury it when there are signs of germination.

Second, the whole stone was soaked in water for the second day, and the skin showed signs of cracking. It is faintly visible that the milky white core is emerging. You can plant it at this time. Put 8- 10 cm soil first, then put it on it, and then cover it with 1 cm thin soil.

Third, the summer temperature reaches above 25 degrees Celsius, which is suitable for the growth of potted durian. There is no need to water every day, the soil humidity is kept at 30%-40%, and insolation is not allowed.

Fourth, when the roots are full of flowerpots, they must be poked out from under the flowerpots and then replaced. Change pots and cut old flowerpots, because durian is not easy to raise.

Precautions for planting:

1, soil preparation.

The garden for planting durian should choose flat land or gentle slope land. Before planting, we should use machines to dig deep into the land. Then leveling can kill harmful substances in the soil, loosen the soil and promote soil respiration.

2. dig a hole.

After choosing the garden site, you should dig a pit, and the depth of the pit should not be too deep or too shallow. Because it is too deep, it is not conducive to the breathing of seedlings.

The excavated cave is about 1 cm wide and 0.8 cm deep. When digging a hole, the soil on the surface should be stacked separately from the soil at the bottom.

Extended data:

The growing environment of durian tree

The average daily temperature is above 22℃, which can be planted in frost-free period and developed in parts of Hainan Province and Yunnan Province.

Because durian can only grow and bear fruit in the climate with high temperature all the year round, even in the equatorial region, the highland above 600m above sea level can not grow durian or bear fruit because of the temperature drop.

Fruiting time of durian tree:

Durian is planted by saplings, and there are many varieties, so the fruiting time of different varieties is different, and it may take 15 years at the longest to start fruiting.

Heavy species take 8 years to bear fruit, including Ina and Gambon.

Medium-sized species will bear fruit within 6 to 8 years, including cereals and long stems;

Light varieties generally only need 4 to 5 years to bear fruit, many of which include Jinzhen, Yiluan, Harufuji, Chani and Jiaoluntong.

The efficacy of durian:

1, keep fit: durian is rich in nutrition and can make the body stronger.

2, relieve menstrual pain: Durian is a kind of hot fruit, containing effective ingredients to relieve menstrual pain.

3, promote appetite: durian because of its unique smell, many people do not like to eat, but this unique smell can make people who have no taste in their mouths open their appetite.

Eating taboos of durian;

1, durian should not be eaten too much at a time, otherwise it will cause the body to be hot and dry, and its rich nutrients will also cause excessive internal heat due to insufficient absorption by the stomach.

2, durian has a high sugar content, and diabetic patients are prone to increase blood sugar after eating, which aggravates the condition.

3, durian is hot and stagnant, so people with hot constitution or patients with sore throat, cough, cold, tracheal sensitivity and diabetes are not suitable for eating durian, otherwise it will definitely aggravate the condition.

4. Durian should not be eaten with wine. The two foods are similar in nature and will cause damage to the body after eating.
