Evergreen mango trees are actually "red in red"

There are two colors of leaves on a tree

Recently, the reporter saw near the bus station of Hubin Middle School that most of the green trees on both sides of the southern Hubin Road were mango trees, and many of them had been hung with fist -sized, colorful or golden or golden fruits.

Interestingly, unlike the green mango trees with green oil oil, some mango trees along the way grow obvious red branches at the top. What's more special is that the same tree grows different colors of leaves, and some leaves are still green, but some leaves become red.

Different sections of fruit loss are different

There are less fruit drops in the main road, and there are more fruit drops in the branch path

On the southern road of Hubin, the reporter walked hundreds of meters along the way and found that the drop of mango was mainly concentrated on the car road, and the number was very small.

However, on the small roads such as Xilin West Road and Wolong Xiaocheng, a lot of mature mango dropped on the road of less than 100 meters. These drops of mango are scattered on the sidewalks and car roads, and some have fallen into the tree to park the vehicle's wiper, hood and under the wheels. Many of them have been flattened and broken, and the splattered flesh exudes odor on the ground, leaving dark yellow marks.

【Questions】

Why is there less fruit?

Two spraying medicine controls flowers to make the fruit less fruit fall

Why does the mango on the main road become less? The reporter asked Chen Shuilong, the chief of the Greenland Supervision Section of the Municipal Greening Center and a professor -level senior engineer.

"There are relatively few mangoes that have fallen as a whole in the city this year. First, because the temperature has risen at the beginning of the year, some mango trees that are sensitive to temperature have blossomed early and have been concluded once, so there are fewer trees in the subsequent results." Chen Shuilong said. June to July is a mature period of local mango trees. However, due to the temperature, mango trees bloomed from November to December last year. After the pouring of insects, some mango trees were first released in March. In addition, in order to reduce the pollution road surface of mango, in March of this year, the city took a large amount of flower control measures when a large number of mango trees blooming on the roadside, and sprayed the mango trees on the main road two times to make the mango tree fall into the flowers in advance, and also reduced the flowers and reduced it. Followed fruit.

Why do trees rush red buds?

Climate cause causes mango tree growth disorders

Why do mango trees grow red buds and red leaves? Chen Shuilong said that the mango tree is not "sick", but its newly growing bud. This year, because of the temperature earlier, some mango trees had the growth process, so that some of the combined mango trees "quickly" growing the buds, and the phenomenon of new shoots (red buds, red leaves) in the ripening period appeared. In addition, when the maintenance team conducts daily maintenance of mango trees, the continuous differences of pruning and leaves will also lead to different branches of the same mango tree in different growth stages. Over time, the red leaves on the mango tree will gradually become green.

Can green manges be eaten?

Or there are heavy metals and pesticide residues.

The mango on the street fluttered, and some people couldn't hold back. Mr. Wang, a citizen, said that recently, I saw that an elderly person picked the mango on the street by long rods and took a bag to take it away. Mr. Wang's doubt: Can the fruit of the green mango tree really eat?

Chen Shuilong said that greening is a public landscape, and it is uncivilized. The mango trees on the streets are not planted in accordance with the standards of edible mango. They mainly play a role in greening cities and do not baggage. Therefore, most of the dust and car tail gas will be absorbed by the leaves and peels of the mango tree. In order to prevent diseases and insect pests, the municipal garden department will also spray potion regularly, and the fruits may contain harmful substances such as heavy metals and have pesticide residues.
