Why are there so few citrus trees in the north and most citrus trees are in the south?

The so-called "orange born in Huainan is orange, born in Huaibei is orange", the meaning of this sentence is that the orange tree is in the Huai River.

To the north, they become a different species and do not grow true citrus. Although this sentence is not quite true, it also roughly explains why orange trees can only be grown in the south and not in the north.

The main problem is the climate, the orange tree can grow well in the warmer climate of the south, and the fruit is relatively large and the taste is richer. In the north, because of the cold weather, many orange trees either can't survive the winter and freeze to death, or the fruits are small and sour, and the taste is very bad. Therefore, orange trees are mainly grown in the south, and it is for this reason that they are rarely found in the north.

Climate issues have led to many fruit trees being able to grow only in certain regions, and these fruits are often uncompetitive beyond this region. Or its planting cost is higher, there are more pests and diseases, and the fruit produced is not satisfactory.

For example, tropical fruits.

It is basically planted in Yunnan, Guangxi, Guangdong, southern Taiwan and Hainan. In other regions, these tropical fruits are often ungrown. Tree species such as cherries and apples are basically planted north of the Huai River, because these tree species cannot bear fruit in the south.

Apples tend to die in less than a year after they grow in the south, while cherries may grow in the south, but the fruit is very small and the taste is sour, because cherries need a colder environment to produce fruit.

Hunan, Jiangxi and Guangxi are the three major producing areas of citrus, Hunan tangerines are planted very extensively, and Jiangxi is dominated by navel oranges.

The most famous, Guangxi is more common with emperor oranges. Although Guizhou, Sichuan, Chongqing, Yunnan, Guangdong, Zhejiang, Fujian and other places can grow citrus. However, the yield and quality of citrus in these places are not as well-known as those of the three citrus producing regions mentioned above, and the taste is better.

Therefore, the vast majority of citrus in the country comes from the three major production areas mentioned above. <>

Of course, for these places where citrus can be grown, many of the citrus in the local market are also produced locally. After all, the ** of ordinary citrus is not high, but the transportation cost accounts for the majority. So if citrus can be produced locally, then the local production will be more competitive, because it can be more affordable.

Not only are citrus from the three major producing areas of Hunan, Jiangxi, and Guangxi more common, but pomelo is also mainly produced in these three places. Whether it is red or white, the quality of grapefruit from these origins will be better.

The back is damp and damp, making it unsuitable for citrus growth.

Hello friends, why sugarcane citrus is not planted in the north, that may be the climate in the north is not very adaptable.

Why didn't the citrus choose to be planted in or to the north of Tongpai?

The various factors in the environment that affect the life of organisms are called environmental factors, which are divided into abiotic factors and biological factors Abiotic factors include: light, temperature, water, air, soil, etc. Biotic factors refer to other organisms in the environment that affect the life of a certain organism, including organisms of the same species and different species The temperature is different in the north and south, and citrus is a tropical fruit that grows well in the south with high temperature; It does not grow well in the north with lower temperatures, and the low temperature affects the quality of citrus

What are the climatic conditions in the northernmost region of citrus cultivation:

1.Temperature effects.

The main factors of citrus cultivation and distribution yield and quality are also inseparable from temperature, so it is more suitable for the temperature at which citrus begins to grow, and the rotation needs to be about 23 degrees, if the temperature exceeds 39 degrees, it will stop growing, so the expiration date will also have a great impact on the growth of citrus, in China's citrus production areas, the general annual accumulated temperature needs to reach 8250 degrees.

2.Lighting conditions.

I feel that I can't do without sufficient light when growing, so his adaptation to light is also particularly wide, in China's citrus production areas, his annual sunshine, the speed is about 1800 hours per hour, general performance, in addition to his growth fruit quality is very good, and citrus is more difficult, because he prefers to grow, in the condition of scattered light can improve photosynthesis, because the direct light is too strong, it will have a great impact on the growth of citrus, and at the same time will not only burn the branches and fruits, but also make his growth slow, Therefore, when planting citrus, the planting density must be reasonable to be conducive to the growth and fruition of citrus.

3.Moisture requirements.

Citrus can't grow without plenty of water, so it needs to receive 1,250 mm of rainfall per year. Therefore, in the citrus growing season, if there is a lot of precipitation, you can do a good job of draining it, and if you encounter a dry season, you can carry out proper watering.

4.Topography of the soil.

Citrus is more suitable for growing in plains, hills, mountains and other areas to grow better. Although his requirements for soil are not particularly strict, it is more suitable for growing in sandy soil, red and yellow soil, etc. If the soil is deep and has a high content of organic matter, it will stand on the growth and development of citrus roots.

Generally, the pH value of the soil needs to be more suitable. If the pH value of the alkaline soil reaches above, it will lead to problems such as dwarf growth of citrus and yellowing of leaves, so it is necessary to check in advance when planting.
