The citrus peel sold on the market is smooth, uniformly colored, the color is orange and yellow is very beautiful, of course, there is a good appearance that lacks the inner flesh beauty will not be loved by consumers, and the best-selling citrus not only has a stunning appearance but also has a good taste of moderate sourness, fruity and juicy, such citrus is favored by many customers. But many farmers report that although the appearance of the citrus they have worked hard to grow is no different from other citrus, the flesh is very sour and bitter. After research, it has been found that most of them are caused by these reasons:
First, the acid contained in citrus is citric acid
Citric acid in the development of citrus rapid accumulation, when the fruit is ripe citric acid will slowly emit acidity weakened, but many farmers feel that the surface of the citrus yellow is already ripe, so eager to pick and immediately market for sale, do not know that at this time the citrus is only the skin ripe but the pulp has not stopped developing at this time Citric acid has not yet fully dispersed Most of it still stays in the pulp of the citrus, so the citrus will be very sour and some bitter, It is bitter because the enzymes in citrus are active in the pulp when the citrus is not ripe and the enzymes are stable only after maturity.
Second, the reason for the variety
Citrus varieties are different, the taste of the plant is the same, and by the influence of many factors from the outside world such as light, precipitation, temperature, geographical location and other conditions will affect the sweetness and quality of citrus, insufficient light and insufficient moisture temperature will cause crop growth and development problems so that the accumulation of sugar is insufficient, farmers' planting and cultivation technology is also a very important aspect, whether there is reasonable fertilization, whether there is time to cultivate the soil, there is no injection of nutrient solution are the reasons that affect the taste.
Third, if the above reasons really appear in the planting of fruit farmers, do not worry too much, as long as it is not the problem of seed selection, you can save the citrus, probably can be improved from the following aspects:
1. Reasonable planting according to local conditions
As the old saying goes, good oranges are born in Huainan, and oranges are born in Huaibei, and planting the right quality in the right area is the most important thing.
2. Reasonable fertilization of feeds
Although nitrogen fertilizer has the effect of increasing yield, if it is applied excessively, it will reduce the quality of the fruit and produce sour oranges.
3. Regularly prune the trunk
Citrus can only be photosynthetic for sugar deposition in the case of sufficient light, so in the spring and summer seasons, it is necessary to do a good job of pruning, appropriately remove dense branches and spring shoots, and improve the ventilation and light transmission conditions in the inner chamber of the canopy.
4. Reasonable pruning
It can increase the total sugar amount of citrus, reduce the total acid amount, and increase the sugar-acid ratio. Harvesting do not be too hasty, citrus peel becomes orange-yellow after there is a period of time before the pulp can be fully ripe, appropriate delay in harvesting, the effect of improving quality is more obvious, in terms of harvesting, do not pick early or ripe.
