How to promote the precocious ripening of sugar orange

In recent years, the price of sugar orange is not satisfactory. In the past, the price was 4-5 yuan per jin, but last year it was only 1-2 yuan per jin, which makes many fruit growers earn nothing, but the price in some precocious areas is very good. So many people want to promote the early ripening of sugar orange and get a good price, so how to promote the early ripening of sugar orange? Let's get to know it.

1. Adequate supply of fertilizer and water

First of all, to ensure that sugar orange has adequate fertilizer, we need to pay attention to the reasonable application of nitrogen fertilizer, water and trace elements, so that fruit trees have sufficient nutrients to grow, so that they can mature earlier. But it is not to apply fertilizer when it is about to mature, but to do it well in the morning to ensure that the fruit trees have plenty of fertilizer and water.

2. Temperature

The next step is to start from the temperature. For example, sugar tangerines in Guangxi are late-maturing varieties. The main reason is that the photosynthesis of sugar oranges is blocked and it is difficult for the peel to change color because of the low temperature and reduced light in winter. So it matures later. So if you want to change its color in advance, you can change the temperature by covering the film. Cover the film when the temperature is low in winter, so that the temperature in the film is higher to meet the requirements of fruit coloring, so as to promote early ripening, generally only need to cover the film for about half a month. However, covering the film also requires cost, and not all can be covered with film. Generally, the color of the film can be changed when it is about to mature, and at the same time, it can also prevent frost damage.

3. Chemicals to promote ripening.

In order to mature sugar orange early, improve the control of fertilizer, water, temperature and light assistance, the technology is more difficult, and some of them have no effect. At present, there are all kinds of colorants on the market, and the effect is excellent after spraying, but the colorant is also an auxiliary means, only to speed up the coloring of sugar orange, if the winter temperature has been very low and lack of light, the effect of simply using colorants is not ideal, and it still needs to be assisted by controlling the temperature. At this time, you still need to cover the film.

The above is how to promote sugar orange precocious introduction, in short, it is not easy to make sugar orange precocious, after all, it belongs to precocious varieties must be precocious, then the cost is very high, we should be careful before carrying out.
