How should mandarin oranges be planted and managed to ripen early?

In recent years, the price of mandarin oranges has been disappointing. In the past, the price was 4-5 yuan per jin, but last year it was only 1-2 yuan per jin, which meant many fruit growers barely made any money. However, prices in some early-ripening regions were very good. So many people want to promote early ripening of mandarin oranges to get a good price. So how do you promote early ripening of mandarin oranges? Let's find out together.

1. Sufficient supply of fertilizer and water

First of all, make sure the mandarin oranges have sufficient fertilizer. Pay attention to the reasonable application of nitrogen fertilizer, water, and trace elements, so that the fruit trees have enough nutrients to grow, and in this way they can ripen earlier. However, this does not mean applying fertilizer when the fruit is about to ripen; rather, it should be done well from the very beginning to ensure the fruit trees have sufficient fertilizer and water.

2. Temperature

Next is to start with temperature. For example, mandarin oranges in Guangxi belong to late-ripening varieties. The main reason is that winter temperatures are too low and sunlight is reduced, which hinders photosynthesis in the mandarin oranges, making it difficult for the peel to change color, so they ripen later. Therefore, if you want them to change color earlier, you can solve this by covering with film to change the temperature. When winter temperatures are low, cover with film, so that the temperature inside the film is higher, meeting the requirements for fruit coloring, thereby promoting early ripening. Generally, only about half a month of film covering is needed. But covering with film also costs money, and not every place can be covered with film. Generally, film is used for color change when the fruit is about to ripen, and it can also prevent frost damage.

3. Chemical agents to promote ripening

If you want mandarin oranges to ripen earlier, improving the control of fertilizer and water, temperature, and light assistance involves relatively high technical difficulty, and some people do it without effect. Nowadays there are various colorants on the market, and the effect after spraying is extremely good, but colorants are also just an auxiliary means; they only speed up the coloring of mandarin oranges. If winter temperatures remain very low and there is a lack of sunlight, the effect of using colorants alone is also not ideal, and it still needs to be assisted by controlling temperature. At this time, film covering is still needed as well.

The above is an introduction to how to promote early ripening of mandarin oranges. In short, making mandarin oranges ripen early is still not easy. After all, if a late-ripening variety is forced to ripen early, the cost paid is quite high, so be cautious before doing it.
