I want to plant a tree in my yardApple treeWhat? A friend from the south will look at this
The question “can apple trees live in the south?” is thought out by a lot of friends in the south. The answer is a little bit subtle: trees may not die, they may be difficult to eat, and it is harder to earn money on. Why is the fruit tree so sarcastic? Let's have a chat。
Let's start with winter. Apples are home in temperate zones, and each winter has to be firmly “sleeping”, which is not short — it needs to remain at temperatures below 7. 2°c, cumulatively 800 to 1,500 hours. But what about the southern plain winter? Temperatures hovered at 10°c every year and trees were “sleepless”. If you don't sleep well, spring is a mess: some of them don't have flowers, some of them bloom, and this year they're all gone, working for half a day。
It won't be easy to survive the winter and the summer test is worse. The apples are born hot and can warm between 7 and 14°c in the most comfortable years, and it's best not to exceed 24°c in the summer. In the south, 35°c rises up, and leaves the fruit tree torn apart, but the buds fail to divide. Even when it's barely fruity, it's burnt, it's dark, it's sweet。
More rain is a disaster. The old saying, "the water is overflowing, the apples are the ones who fear flooding, and the ideal is to drink 500 to 800 millimeters of water next year. In the southern part of the rainy season, the fields are so wet that water can be wringed out, anthrax, wheel-lined diseases are raging, and aphids follow, with roots in the water for long periods of time. When it rains when it comes to flowering, pollen is washed by rain and pollination success drops to the bottom of the valley
The light and the temperature difference are two things
Your majesty, the south is also lacking. Apples require at least 2,200 hours of sunlight a year to produce a good look, and the temperature difference between day and night is high enough for sugar to sink. The southern sky is always gray, and the temperature is not cool at night, and the fruits are tedious and soft in a few days。
The soil is also sad. The red yellow border in the south is sour and adhesive, and it has a bad air flow, and it is completely two-way with apple-loved pine sand. I'd like to plant it. It's expensive to spray lime with acid, to fertilize organically, to dig ditches and drain。
There are always exceptions. The high-altitude areas of yunnan, guizhou, sichuan sunshan, are between 1,600 and 2900 metres above sea level, with cool summers, strong sunlights, alarming temperature differentials between day and night, and the high quality of apples planted, as evidenced by their reputation. There are also a number of species with particularly low cooling volumes, such as anna and dorsett golden, who can experiment in fujian, zhejiang and guangdong on a small scale or make a flower pot to watch. But, to be honest, it's a lot of money, and it's still a lot worse than the northern apple。
In the end, there are no good apples in the south because winter is not cold enough, summer is not cold enough, rain is too heavy and temperature is too low. Trees don't have to grow. They don't taste good. They don't work. It is only right that the right tree species should be placed on the right land rather than the right skin。
