Caiye pear is a foreign colored tree species that has been hyped by the market since 2014, and in recent years, its popularity has even surpassed that of American red maple.
It has become a cultivar that many seedling farmers flock to, and nurseries across the country compete for planting. 1 meter tall seedlings, priced as high as 120 yuan / tree, are still in short supply.
Pears are autumn colors in the United States
The reason why the coleus pear is sought after by the market is that its fiery autumn color is very eye-catching, and it is also one of the tree species that constitutes the autumn color of North America (the five tree species of American red maple, North American sugar maple, North American bean pear, American purple tree, North American red oak and so on are the main varieties of North American fiery autumn color).
Autumn colors in American nurseries
In fact, pears are not unique to the United States, but are also widely distributed in China, shandong, Henan, Jiangsu, Zhejiang, Jiangxi, Anhui, Hubei, Hunan, Fujian, Guangdong, and Guangxi.
However, China's pears do not change color in autumn, and the potato pears in the American countryside are also discolored, and they are horticultural varieties that have been artificially cultivated after continuous genetic improvement, and the autumn color is so bright red.
Pears from the Oregon Nursery
Bean pear briefly introduced, so go straight to the theme, why planted color leaf pear in the area south of the Huai River will have no return, a dead end?
Here are three main conditions for analyzing the color change of color leaf pear in autumn:
First of all, the temperature difference between day and night is greater than 12 °C-15 °C;
Secondly, the air humidity cannot be greater than 50%;
Again, the soil pH cannot be greater than 8.0
Knowing the discoloration conditions, then the answer also comes out: in the area south of the Huai River, the temperature difference between day and night in autumn and winter is difficult to reach the temperature required for discoloration, and the air humidity in autumn and winter is difficult to be less than 50%, which causes the color leaf pear to be unable to change color, or the discoloration effect is very poor, far from the expected effect.
The actual color change effect of the nursery south of the Huai River in autumn
Theoretically, the analysis of the color leaf pear in the autumn and winter south of the Huai River does not change color, let's look at the actual nursery experience, after all, facts speak louder than words.
The actual autumn color of the nursery is pig liver color
Zhejiang Senhe Group, as long as it is engaged in the nursery industry for more than 10 years, should be no one knows, red leaf heather is Senhe Group in 2000 from the United States introduced, and then promoted in China.
In 2010, Senhe Group imported many colorful leaf pears from the United States and planted them in nursery bases in Zhejiang, Sichuan, Shandong and other nurseries.
After its introduction to China, it was planted in the south with colorful leaf pears
Although the autumn color performance in the United States is very eye-catching, but after the introduction of China, the autumn discoloration effect is not ideal, in these 10 years, only 2-3 years of discoloration, and are pig liver color, the time is relatively short, only one week, the leaves are all gone.
Actual effect of the nursery changing color in autumn
In addition, the rust of the colorful leaf pear is very common, especially in the summer, until the autumn leaves fall, rust erodes most of the leaves, seriously affecting the health and beauty of the tree.
Rust that is difficult to control
Rust is the biggest obstacle to the application of color leaf pear into landscaping projects, nursery control rust is more cumbersome, if applied to the project, the prevention and control of rust will be more difficult.
The ultimate goal of seedling cultivation is to be applied to the actual garden project, and the maintenance and management of the project cannot be compared with the nursery.
The autumn colors of the nursery are so unsatisfactory, the rust is so serious, the actual effect of the project can be imagined.
Therefore, planting colorful leaves and pears south of the Huai River will inevitably lead to a dead end. Moreover, the northern nursery must not blindly follow the trend.
Current big tree project price:
In the winter of 2019, the price of the "Autumn Flame" variety of "Autumn Flame" varieties of rice diameter on the market is about 4500-5000 yuan, and there are several nurseries in the country, and the supply is in short supply. About 100 trees can be planted per mu, and the income of one mu of land is at least about 450,000 yuan.
It is easy to get 450,000 acres
These nurseries planted the pear with colorful leaves 6-7 years ago, which is the earliest in the country, they seized the opportunity, and now they are rich. There is a Shandong nursery, in 2014 planted a total of 750 acres of colorful leaf pears, 2019 valuation of 370 million yuan!
750 acres of colorful leaf pears
Future market expectations
In the winter of 2021, the price of large-sized color leaf pears has begun to fall, falling by about 10%, because the large trees with growers have slowly come to the market.
This speed has been accelerating in 2022, it is estimated that in 2025, the supply of color leaf pear trees will show a blowout, that is, the price will not exceed 700 yuan / tree, and it may be unsalable, and finally when the firewood is burned.
Therefore, this variety can no longer be planted with the trend, and the south, needless to say, is not suitable at all. The north can no longer follow suit.
To sum up a sentence: planting new varieties of seedlings can make a lot of money, but we must be early, and those who follow the trend in the back are likely to lose their money. Success and failure lie in a race against time, and whoever runs ahead will be able to make a lot of money.
How to tell if a new variety has been planted by many people?
Without having to go around surveying, it's a simple way: do you see if you can buy seedlings of this variety everywhere? And cheap? If so, then don't buy it.
Because there are too many people buying seedlings, the big trees will certainly not be worth much in the future. This method has been tried and tested.
The easier it is to get, the less valuable it is.
