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. Investigate its reason, there are several reasons:

1. Nowadays, 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 influenced 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 in urban streets are not picked.

Although some people in the city don't think that there is any pollution or poor quality of street greening fruit trees, they think that street fruit trees are mainly used for people to watch and shelter from the wind and rain, and fruit trees are used by all citizens. 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 are sprayed with pesticides to prevent insects and diseases. In addition, there are no conditions for applying 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 are there no people picking the fruits all over the street? The most important reason is that people's material life is rich and there is no shortage of food.

If you want to eat in the store, it will 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 have to do such a disgraceful thing.

This also reminds me of many fruit trees 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. On the one hand, they have no time; on the other hand, 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 in groups to see who picks more, and they also eat with relish. Although it tastes worse than those bought in the market, it is a pleasure 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 will help them to eat, just for fun.

However, some old ladies are another matter. The purpose of picking them is to make loquat dew. Pick these ripe loquats home, peel off the 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. If they are poor, they are all 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.

Everyone thinks that the reasons for not eating are nothing more than a few points, such as pesticide residues, excessive heavy metal content caused by absorbing tail gas, bad taste 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 come and go, so many people take it for granted that green radish will be polluted by exhaust gas and rich in 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 lead 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 in the 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 radish for evaluation, and wrote the evaluation according to sweetness, taste and stone. These three kinds of green awns are very sweet, but the taste is different from the stone, which is estimated to be related to the variety.

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 very dangerous to pick them. When I meet people who pick green mangoes, they always poke 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 cars. It is easy to fall or get an electric shock when climbing trees for picking. There are a lot of news about the death of picking green awns on the Internet, such as "A man climbed a tree to pick mangoes on Yingbin Road in Hui 'an and was suspected of electrocution" and "A man in Wuzhou picked mangoes by the roadside and accidentally fell to his death! In order to pick this "green awn", two men accidentally fell from the tree on the same day. "

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

In short, regardless of whether the green awn can be eaten or not, it is not recommended to take risks in picking.

In people's ideology, the fruit trees on the street are for viewing, they are landscape trees, not edible fruits. Therefore, they can only be seen from a distance and cannot be picked.

Shenzhen is a newly-developed city 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 value is generally good. They are unwilling and unwilling to destroy the environment, affect their appearance and damage the public image in order to find an excuse.

In addition, ornamental fruits generally taste bad, and people disdain to eat this kind of food. In particular, due to the traffic of cars on urban streets, the exhaust pollution is serious, which will cause certain pollution to flowers and trees on 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 so fast that they have little leisure time. If they have a little leisure time, they would rather go to entertainment places than do such boring things as picking street fruits.

Not only in Shenzhen, but also in many cities, the ornamental fruit trees are well preserved, which reflects the advanced management culture of the city on the one hand, and the civilization and self-discipline of modern urban people on the other.

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

No one will pick mangoes everywhere in the streets of Shenzhen, but when they are ripe, they will fall to the ground. 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. If they encounter a famine year, let alone fruit, even the skins of fruit trees are 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 about picking green belt fruits?

There are also many fruits in the green belts on both sides of Chongqing Road, especially peaches, which are everywhere in spring and nobody picks them in summer! With the improvement of people's living standards, people's overall quality is not backward. Green fruit will not be delicious, but it is 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 fruits in the green belt are left unattended, the city Council will clean and disinfect the city appearance within a certain period of time. These unattended fruits will be disinfected and cleaned like other vegetation in the green belt. 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 of quality. With the improvement of living standards and quality, it can be seen that people will still choose greener and healthier fruits and vegetables even if the quality is good and they grow in different places.

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. Besides, mango is too small to be beautiful. Mango planted in a quiet place in our home is not sprayed with drugs, and there is no automobile exhaust or even smoke. Mangoes that fall to the ground will not be picked up. Some small lychees and longan are not picked on trees, because the materials are too rich.

Green awn absorbs automobile exhaust and 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 many green trees on both sides of the roads. The reasons for choosing mango tree as greening tree are as follows: First, mango tree has a straight trunk, a straight tree shape, lush foliage and good shading. Secondly, mango trees have strong adaptability to the environment. Third, mango trees are evergreen in all seasons 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.

As a green tree, mango trees will inhale a lot of carbon dioxide, automobile exhaust and harmful substances, so the mangoes will absorb more heavy metals, and eating too much will be harmful to people's health.

Another point is that greening trees belong to the jurisdiction of municipal gardens, and citizens are generally forbidden to pick 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, so it is generally forbidden for the public to eat.

This ornamental mango is widely planted in Guangdong. But many outsiders don't know, so they are often picked on, which makes a lot of jokes.

A few years ago, it was reported that some old people came from other places to visit relatives in Guangdong, climbed mango trees to pick them, and accidentally fell off the trees 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.

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

The mangoes on the roadside in Shenzhen are not picked by no one, but by only a few people. 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 climbed a lychee 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 matures, and deal with one when it finds one. Now, litchi park will even "disinfect" litchi trees in advance, that is, spray drugs to make the flowers fall off during the litchi flowering season, 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 mangoes sold in fruit shops and supermarkets. Ten years ago, it was impossible for these mangoes to grow into a mature season. They will 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 of all, with the improvement of people's living standards, fruits such as litchi and mango 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, because of the influence of automobile exhaust on the roadside 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 roadside may spray drugs, which leads to 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, so they are not suitable for eating.

Fourth, our city pays more and more attention to the protection and publicity of green fruit trees. In order to reduce people climbing trees and picking fruits, we can see many propaganda signs along the road, some of which are suggestions and some are warnings. With the public's awareness of greening fruits becoming more and more clear, many people have given up the idea of climbing trees to pick 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. In the end, the fruit you pick is not the same as edible or delicious and healthy.

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