Look at this shape of course you know this is not a red maple leaf, I tell you this is Yang Ye you believe it? Yang leaves? Poplar grows red leaves? You do not believe, not only you, many people are also dubious.
Citizen: Poplar? The leaves seem to be green, only seen green, never seen red, and generally what color of poplar you see. Green, have you seen any other colors? No. Haven't you seen red poplars? Never heard of it. Do you believe in red poplars? There should be, everything in the world.
Planters: The people have not seen how the red leaves are red. It seems that they haven’t seen them. They are very strange and very rare. I’ve seen from the data that the red poplars are not only in our country but not in the international community. See the report about the poplar.
Yang Shuji, who is born with green leaves, grows red leaves. It hasn't been seen anywhere. I haven't seen it yet. Why don't the people show up as strange and strange?
Cheng Xiangjun, Director of the Hongyang Green Nursery Nursery Research Institute, Shangqiu City, Henan Province: At the time in April 2000, I planted 300 mu of American poplar on our farm. One night, we went to the fields to see the pests and diseases. When I looked at a tree seedling and looked at it with red and green, I thought at the time that if this color could be maintained, it would be a good tree species in the greening of the garden. At that time I would give that seedling to Stayed.
Yeah, the poplar grows red leaves. It's a strange thing. It must be nurtured and nurtured. After five years of meticulous training, the Chinese red poplar, which has been stable and consistent, has finally been recognized as a new breed protected by intellectual property rights by the State Forestry Administration.
Reporter Ouyang Hongying: This poplar tree is widely distributed in our country. It is an important raw material for industrial and civilian materials, and it is also one of the important tree species for afforestation and afforestation. Therefore, there are many new poplar species cultivated at home and abroad, but they are used The appreciation of the garden is not, then the emergence of red poplar, just to fill this gap.
The most important feature of this tree is its three-quarter color change: from germination to mid-May, its color is the color of the whole plant. This whole plant is all red from the middle of May to September. It It becomes red green. After October, the whole leaves turned dark green into such a color. . . . In November, it becomes two colors of orange and orange
Three quarters of color can change, powerful! People said that compared with other European and American varieties of poplar, the effect of greening of Chinese red poplar grows for about 60 days. This kind of poplar is divided into male and female. The female plant will produce a large amount of fly flocks every spring. Therefore, the garden construction is very afraid of this. For example, the relevant departments in Beijing have forbidden the planting of female poplar trees. The red poplar mother strain that was found in that year was male, so from a genetic point of view, the cultivated red poplar was also a male plant.
Luo Mengzhu, deputy researcher of the Institute of Forestry at the Chinese Academy of Forestry Research Institute, Lu Mengzhu: This red poplar is from the mother plant. If the mother plant is male, then it should be male, and he said that there might not be any flying flocks in the future. So if that is the case Then the landscaping is even more important.
This red poplar is fast growing. People can grow 4 centimeters a night.
This is the sign that was inserted yesterday evening. It is 4 centimeters long this night. After entering the fast-growing period, it can grow to 7 centimeters to 8 centimeters within 24 hours. Ordinary colored trees, like purple pears, are not necessarily as long as a month.
From nursery to greening, it takes about one year for red poplar, and it takes five years for other colored trees to be fastest. For a comparison, the same thick trunk, the red plum needs to grow for 5 to 6 years; the red poplar needs to grow for 1 year and a half!
As we all know, poplars have good adaptability and are resistant to cold and drought, and they are easy to cultivate. Red poplar is no exception, but it also suffers from pest and disease intrusion.
Wang Ai-ke, a senior agronomist at the Hongyang Green Nursery Nursery Research Institute, Shangqiu City, Henan Province: As with other poplar species, there is a type of poplar Yang, which is an insect pest that occurred in the third quarter of July and August. However, this insect pest is a very good cure, is to use chrysanthemum lipid drugs or potassium ammonia phosphorus, routine control can be used one or two times.
From the initial discovery, the breeder's sight is precisely the unique color of the Chinese red poplar, and its appearance is exactly in line with the urban greening construction in China. Taking Henan Province as an example, the total area of ​​garden flowers in Henan Province is 470,000 mu. The annual output value can reach 1.8 billion yuan, and the total annual transaction volume is about 500 million yuan.
Expert: From the market point of view, the red color found in poplar varieties so far, especially the stem color, has never been seen before. . .
Many ordinary garden plants are cultivated in the nursery for five or six years or even longer. This one will directly insert a cutting and insert it there. It will be possible to grow it for a year or two. So its potential market is very large. of.
This is a good life. In addition to food and clothing, people pay more and more attention to the living environment. The greening of the city and the development of the western region all require a lot of green seedlings. This red poplar as a fast-growing, cold-tolerant, drought-tolerant, rich-colored tree species should occupy a place in urban afforestation.
Reporter Ouyang Hongying: With the acceleration of the pace of building a new socialist countryside in our country, the intensity of urban and rural afforestation has increased. As a fast-growing poplar, Yangzhong will add new scenery to cities, roads and landscaping.
