What is the reason for the thickness of sugar orange peel?

Sugar orange is a very popular orange variety, which has a great market demand in me. Therefore, the planting area of sugar orange is still very large, and many sugar orange growers often have the problem that the peel of sugar orange is too thick. Not only the appearance of sugar orange will be affected, but also the commodity value will be affected. So what is the reason for the thick peel of sugar orange? Let's take a look at it with the editor.

1. Boron deficiency

Sugar tangerine actually has certain requirements for growing areas, and it is not suitable to grow sugar orange in most southern areas. Because the soil in most parts of the south is sour, and there are more rainy days. Lead to the loss of boron, magnesium, manganese and other elements, so the planting of sugar tangerine in the south is very prone to element deficiency. If there is a lack of boron in the growth of sugar orange, there will be various conditions such as small fruit, peel, acid, deformity and so on. The veins of the leaves will also be very swollen, and the old and tender leaves will have different symptoms.

2. The cause of gibberellin

When growing sugar tangerines, many fruit growers will habitually use some gibberellin. Because gibberellin can promote the division and enlargement of plant cells, rational use of gibberellin is very beneficial to the yield and fruit quality of sugar orange. However, it should be noted that after the sugar orange sits on the fruit, the young fruit is mainly based on the cell wall, and then the pulp is gradually formed. If in the sugar orange fruit protection, gibberellin is used too much, or the concentration is too high. It will lead to excessive division and enlargement of pericarp cells, deformity, skin thickness and so on.

3. Excessive application of nitrogen fertilizer

Sugar orange in the growth, there will be a certain growth law. When applying fertilizer, we should reasonably control the fertilizer according to the law of fruit growth. In general, it is mainly when the fruit is enlarged during the period of 2 to 3 before fruit development. In the last time, the growth center of the fruit will be changed to accumulate dry matter, at this time we must pay attention to control the application of nitrogen fertilizer. If nitrogen fertilizer is applied, it is not only easy to cause the pericarp to thicken, but also to cause the fruit trees to grow and consume too much nutrition. It is very disadvantageous to its yield and fruit quality.

4. Weather reasons

Weather is also one of the main reasons for the thickening of sugar orange peel. In the sugar orange flower bud differentiation and flowering period, if encountered late spring cold, low temperature and other abnormal weather. Then it will hinder the normal development of the ovary of some flowers, although these flowers can pollinate normally and bear fruit. However, after fruit setting, the fruit usually develops poorly, and the dredging system of the fruit is also very poor. Thus affecting the transport of organic nutrients, resulting in fruit deformity, skin thickness.

The above is a brief introduction to the reasons behind the sugar orange peel. Everyone should do a good job in prevention and control work according to specific reasons to reduce the phenomenon of skin thickness. That's all for today's introduction. Thank you for your reading and support.
