No one picks mangoes on the streets of Shenzhen. When they are mature, they will fall to the ground. Why?

This kind of thing is similar in other cities, but the variety of fruit trees is not only mango, but also litchi and plum. There are several reasons for this:

1. Now people have higher requirements for the quality, appearance and taste of fruits. Street greening fruit trees are generally poor in quality and taste. Besides, fruit trees grow on busy roads. It is considered that the growth environment of fruit is greatly affected by automobile exhaust, irrigation water and fertilizer are not up to standard, and the quality of fruit is poor, so it is not suitable for eating. This is also one of the reasons why fruit trees are not picked in urban streets.

Although some people in the city don't think there is any pollution or poor quality of street greening fruit trees, they think that street fruit trees are mainly for people to watch and shelter from the wind and rain, and fruit trees are used by the whole people. Picking fruit trees is ugly and selfish, so these people will never touch the fruit.

In fact, many people have witnessed the situation that fruit trees across the street spray pesticides to prevent insects and diseases. In addition, there is no condition to apply farmyard manure in cities, and the fertilizer used is mainly chemical fertilizer. In addition, the irrigation water standard is not up to standard, the street dust is heavy, there are many automobile exhaust and urban industrial pollutants, and the heavy metal content and pesticide residues in fruit trees produced by Street View are bound to exceed the standard. It may be your best choice not to pick or eat.

Why do you turn a blind eye to the fruits all over the street and no one picks them? The most important reason is that people are rich in material life and do not lack food.

Want to eat in the store, save time and effort, and won't cost you a few dollars. It takes time and effort to pick trees, and it doesn't look good on your face. It seems that you are "poor" and want to do such a "disgraceful" thing.

This also reminds me that many fruit trees are planted in our community, including peach trees and loquat trees.

Every year when loquat is ripe, golden loquat is covered with branches. Most people are busy passing under trees, but they never pick them. They may have important things to do and are busy making money. For one thing, they don't have time; for another, they don't like this little profit.

But there are two kinds of people besides children and old ladies. Nothing is naughty for children. They will compete with each other in groups to see who picks more and eats with relish. Although it tastes worse than those bought in the market, it is a kind of enjoyment for these children.

Old ladies are also interested in playing the pipa. These old ladies are playing in the community with their grandchildren. Grandchildren can't pick them themselves, so grandmothers help them to eat, just for fun.

However, some old ladies are another matter. The purpose of picking them is to make loquat dew. Take these ripe loquats home, peel off their skins and seeds, add sugar and seal them in a container. After a period of fermentation, they became self-made loquat dew, which has the effect of moistening lung and relieving cough.

These old ladies were born in the 1950s and 1960s. Poor people are good at living. They can eat delicious food and exercise without spending money. Isn't it fun?

These old ladies are miracles. I don't know where to find a ladder, and there are some special scissors for pruning branches. A pair of scissors is tied to a long pole, and a string of loquats is cut off by gently pulling the rope. It's amazing!

I spent some time in Shenzhen a few years ago, and I often saw people picking green awns and palm-sized mangoes. When they were picked, they were several big pockets. Mainly the old people and children are picking. I guess young people don't have time. Sorry. Similarly, green jackfruit, green longan and green litchi were also picked.

There are two main schools on the Internet about whether the green awn can be eaten.

One school thinks it can't be eaten; The other group thinks it can be eaten because they have been eating it for many years.

It is believed that the reasons for not eating are nothing more than a few points, such as pesticide residues, absorption of tail gas, excessive heavy metal content, unpalatability and so on.

There are pesticide residues, but there is no authoritative report that the heavy metal content exceeds the standard due to the absorption of automobile exhaust.

Green radish grows on the roadside where cars are coming and going, so many people take it for granted that green radish will be polluted by exhaust gas and enriched with heavy metals. However, on 20 18, xiangcheng district, Zhangzhou City, Fujian Province sent the green awns of Shengli Road and Jianyuan Road to Zhangzhou Customs Comprehensive Technical Service Center for heavy metal content detection. The test results show that the lead content per kilogram of green awn in two locations is less than 0.05 mg, which belongs to the safety range stipulated by food, and the other four heavy metals are also very low.

Detection and analysis of lead content in green mango in Quanzhou: 25 samples of green mango collected from Wenling Road, Pingshan Road, Xingxian Road and Torch Street in Quanzhou were detected by graphite furnace atomic absorption spectrometry, and 14 samples were detected, with a detection rate of 56% and the highest content of 0.086 mg/kg.

According to GB 2762-2017+07, the lead content of fresh fruits (except berries and other small fruits) should be less than 0. 1 mg/kg.

Therefore, at least the lead content of green mangoes in the selected sections of the above two cities meets the safety standards. Other cities have no authoritative testing, and it is impossible to know.

Regarding the taste of green mango, many people who have eaten it say it tastes good.

The netizen selected three varieties of green awn for evaluation, and wrote the evaluation according to sweetness, taste and nucleolus. These three kinds of green awns are very sweet, but the taste is different from that of stones, which is estimated to be related to the varieties.

Many people eat green peppers, but the local media said that green peppers can't be eaten and picking them is not recommended. I think it is mainly related to safety and city appearance.

Green mango trees are very tall and grow on the roadside, so it is dangerous to pick them. When I meet people who pick green mangoes, they all stab them with long poles, which inevitably leaves the ground and affects the city appearance. Waving a long pole on the roadside may cause interference to passing vehicles. Climbing trees is easy to fall or get an electric shock. There are a lot of news on the Internet about picking mangoes and falling to death. For example, "A man climbed a tree to pick mangoes on Yingbin Road in Hui 'an, and was suspected of being electrocuted." "A man picked mangoes by Wuzhou roadside and accidentally fell to death! In order to pick the green awn, two men accidentally fell from the tree on the same day. "

Therefore, the local media publicize that greening awn is harmful, and it is well-intentioned not to pick it. Some cities will arrange workers to pick green awns before they are ripe, and some places will punish the act of picking green awns.

In short, no matter whether the green awn can be eaten or not, it is not recommended to take risks to pick it.

In people's ideology, fruit trees on the street are for viewing, and they are landscape trees, not edible fruits. So you can only see it from a distance, and you can't pick it.

Shenzhen is a new city that has developed rapidly in the process of China's reform and opening up. The high-end atmosphere is classy, but the people here are also elites. People's sense of merit is generally good. They don't want to or don't want to make excuses to destroy the environment, affect the scenery and damage the public image.

In addition, ornamental fruits generally taste bad, and people disdain to eat this kind of food. Especially in urban streets, because of the traffic, the tail gas pollution is serious, which will cause certain pollution to the flowers and trees in the streets. People don't want to eat this kind of food for the sake of health.

Another reason is that Shenzhen is developing rapidly, people's life is too fast, and there is little leisure time. If they have a little leisure, they would rather have fun than do such boring things as picking street fruits.

Not only in Shenzhen, but also in many cities, the ornamental fruit trees are well maintained, which not only reflects the advanced management culture of the city, but also reflects the degree of civilization and self-discipline of modern urban people.

This is my view on this matter. I wonder if my friends agree? Welcome to exchange guidance.

No one picked mangoes in the streets of Shenzhen, but they fell to the ground when they were ripe. Why? Probably because Shenzhen's economic conditions are good and people's material living standards are relatively high, people are not short of those few dollars.

Mangoes in the street have tail gas, dust and sometimes pesticides. Who will you go to in case you eat pesticides? If you want to eat, you might as well spend some money on it at the fruit shop.

The main reason is that people's economic conditions are better now than before, and there is no shortage of those few dollars. In case of famine, let alone fruit, even the skin of fruit trees is gone.

Is there any news about picking fruit from the green belt? Have you seen a doctor for eating green belt fruit by mistake? Have you ever been verbally warned to pick green belt fruits?

There are also many fruits, especially peaches, in the green belts on both sides of Chongqing Road. Peach blossoms are all over the mountain city in spring, but peaches are not picked in summer! With the improvement of people's living standards, people's overall quality is not backward, and green fruits are not very delicious, but they are a landscape that tells the changes of this season.

Don't pick fruit in the street. 1 the fruit in the green belt is not suitable for eating because the long-term growth environment is to purify the air and waste gas. Because the fruit in the green belt is left unattended, the city Council will clean and disinfect the city appearance within a certain period of time. These unattended fruits, like other vegetation in the green belt, will be disinfected and cleaned. The fruit of the green belt, first of all, the quality is difficult to enter the eyes of consumers, and secondly, the green belt is a collective environmental protection belt, and uncivilized behavior is not advocated. People's requirements for fruits and vegetables are qualitative. With the improvement of living standards and quality, it can be seen that even if the quality is good and people grow in different places, people will still choose greener and healthier fruits and vegetables.

Those mangoes were not eaten by insects, nor were they polluted by automobile exhaust. It is shameful to eat mangoes picked up from the ground. And mango is too small to look good. Mango grown in a quiet place in our house has never been sprayed with medicine, nor has it been sprayed with automobile exhaust or even smoke. Don't pick up mangoes that fall to the ground. Some small lychees and dragon eyes are not picked from trees because they are too rich in material.

Green awn absorbs automobile exhaust and contains heavy metals. Eating too much is bad for your health.

Not only in Shenzhen, but also on the main roads in Xiamen Island, mangoes are planted on the green trees on both sides of many roads. There are several reasons for choosing mango tree as greening tree: First, mango tree has straight trunk, straight tree type, lush foliage and good shading. Secondly, mango trees have strong adaptability to the environment. Third, mango trees are evergreen all the year round and are not affected by seasons. The most important thing is that mango trees are resistant to pollution, wind, cold, waterlogging, drought and radiation, and there are few pests and diseases.

Mango tree, as a kind of green tree, inhales a lot of carbon dioxide, automobile exhaust and harmful substances, so the grown mango absorbs more heavy metals, which is not good for people's health.

Another point is that greening trees are under the jurisdiction of municipal gardens, and citizens are generally prohibited from picking them themselves. If mangoes fall and hit people or passing vehicles because of improper picking, it is not cost-effective.

This is an ornamental fruit, which is very different from the edible mango we grow.

First of all, this mango is too bad and bitter to eat at all.

Secondly, this mango will leave a lot of pesticides, which is generally forbidden to the public.

This ornamental mango is widely planted in Guangdong. But many outsiders don't know, so they often pick and make a lot of jokes.

A few years ago, it was reported that an old man came from other places to visit relatives in Guangdong, climbed the mango tree to pick it, and accidentally fell from the tree and died.

Under normal circumstances, most local people are used to it, so they will consciously abide by it and will not pick it.

After these mangoes fall, sanitation workers usually clean them up, so you don't have to worry.

However, this kind of tree also has some shortcomings, which generally causes mosquitoes, which is why we sprinkle some pesticides on mango trees.

I won't feel strange if I stay in Guangdong for a long time in the future! In fact, not only Guangdong, but also Fujian and Guangxi in the south have planted roadside awn.

The mangoes on the roadside in Shenzhen are not picked, but few people pick them. Now some playful or curious young people have nothing to do, or some old people and children prefer to do this kind of thing. I came to Shenzhen on 20 1 1. Ten years ago, I found a very common phenomenon. In summer, mango trees on both sides of roads in Shenzhen and litchi trees in parks are fruitful. At this time, many people like to climb up and pick them.

I witnessed such a thing when I was playing in Futian litchi park. When a young man was climbing a litchi tree to pick lychees, he accidentally fell down and was unconscious. He was taken to the hospital by ambulance. Later, in addition to hanging a sign on the tree "No climbing at your own risk", Litchi Park will send people to patrol when it is mature, and deal with one when it finds one. Now, litchi park will even "disinfect" litchi trees in advance, that is, spray drugs at the flowering stage of litchi to make the flowers fall off, thus effectively preventing tourists from climbing trees and picking them.

Even the green fruit trees on both sides of the road are even a bright spot, especially mango trees. When mangoes are ripe in summer, the mango trees on both sides of the road are covered with green mangoes, which are more attractive than those sold in fruit shops and supermarkets. Ten years ago, it was impossible for these mangoes to grow into a mature season, and they can be picked soon after they grow into fruits. But now, we find that there are fewer and fewer people picking litchi and mango. Why is this? I think there are only the following reasons:

First, with the improvement of people's living standards, litchi, mango and other fruits are no longer "unaffordable" fruits, but very common fruits. People will not try their best to pick the fruits of green fruit trees in roads and parks as before.

Secondly, due to the influence of roadside automobile exhaust all the year round, the fruit of green fruit trees is actually not delicious. The appearance, taste and nutritional value of these fruits are much worse than ordinary fruits, so they are not worth eating.

Third, the fruit of green fruit trees may have safety problems. In order to prevent insects and treat diseases, fruit trees in parks or roadsides may spray drugs, resulting in the problem of drug residues. Secondly, influenced by the environment (such as automobile exhaust and industrial waste gas), the fruits of green fruit trees may have excessive heavy metals and are not suitable for eating.

Fourthly, cities pay more and more attention to the protection and publicity of green fruit trees. In order to reduce people from climbing trees and picking fruits, we can see many publicity signs on the roadside, some of which are advice and some are warnings. As the public's understanding of greening fruits becomes clearer and clearer, many people give up the idea of climbing trees and picking fruits in a subtle way.

In fact, although it is not illegal to climb trees to pick the fruits of green fruit trees, through the above analysis, we think it is a very immoral behavior and an adventurous behavior. First of all, climbing trees in public places is an uncivilized behavior. In fact, climbing trees is risky for your own safety. Finally, the fruit you pick is not the same as edible or delicious and healthy.

So in general, please don't climb green fruit trees at will in this ripe season of litchi and mango, and be a civilized citizen!
