The Latest Methods to Promote Early Ripening of Sugar Mandarin Oranges

In recent years, the price of sugar 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. This left many fruit growers with little profit, but prices in some early-ripening regions were very good. So many people want to promote early ripening of sugar mandarin oranges to get a good price. So how should you promote early ripening of sugar mandarin oranges? Let's find out together.

1. Sufficient fertilizer and water supply

First, you need to ensure that sugar mandarin oranges have sufficient fertilizer. You need to pay attention to the reasonable application of nitrogen fertilizer, water, and trace elements, so that the fruit trees have sufficient nutrients to grow, and in this way they can ripen earlier. But it is not about applying fertilizer when they are almost ripe; rather, it must be done well from early on to ensure the fruit trees have sufficient fertilizer and water.

2. Temperature

Next is temperature. For example, sugar mandarin oranges in the Guangxi region are a late-ripening variety. The main reason is that winter temperatures are too low and sunlight is reduced, which hinders photosynthesis in sugar mandarin oranges and makes it harder 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 and thus promoting early ripening. Generally, covering with film for about half a month is enough. But covering with film also costs money, and not everyone can cover with film. Generally, film is used when the fruit is almost ripe to promote color change, and it can also prevent frost damage.

3. Chemical agents to promote ripening

If you want sugar mandarin oranges to ripen earlier, improving the control of fertilizer and water, temperature, and light assistance has a high technical difficulty, and sometimes it has no effect even after doing it. There are now various coloring agents on the market, and after spraying, the effect is excellent. But coloring agents are also an auxiliary means; they only speed up the coloring of sugar mandarin oranges. If winter temperatures remain very low and there is a lack of sunlight, the effect of using coloring agents alone is also not ideal, and it still needs to be assisted by controlling temperature. At this time, film covering is still needed.

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