What fruit trees are there in the north, and why do they taste sour?

Now is the peak season for citrus production, and the shadow of citrus can be seen everywhere on the street, but if the citrus taste sour, it will often be lower. So why do some citrus have a sour taste? If you want to sweeten citrus, what do you need to pay attention to when fertilizing?

1. Why does citrus taste sour?

1. The root system is damaged (rotting, burning roots, etc.) and cannot absorb nutrients normally, and insufficient nutrients are not conducive to deacidification and sugar increase. The annular cut is not completely healed, the nutrients cannot be transported normally, the fruit tree can not die, the nutrients are insufficient in the later stage, the tree is weak, the fruit is colored early, but the taste is sour.

Note: Insufficient light, too much water from the coloring period to the ripening stage, or the application of high nitrogen fertilizer will lead to low sugar content.

2. The application of fertilizer containing organic matter is less, which is not conducive to reducing acid and increasing sugar. Lack of potassium fertilizer at the fruit expansion stage can not be good deacidification. The lack of phosphorus and potassium fertilizer during the coloring period is not conducive to the accumulation of sugar and coloring.

As a citrus grower, it doesn't matter if you understand the theory or not, you can plant the fruit well, and the senior farmers summarized the sweetness of the fruit during the fruit expansion period "peanut bran + potassium fertilizer", and there is no reason why the fruit is not sweet, even if the inner fruit is sweet. Peanut bran contains high organic quality, which is conducive to reducing acid and increasing sugar, of course, it is not necessary to apply peanut bran, you can also use rotten farmhouse fertilizer, commercial organic fertilizer, bacterial fertilizer, etc., and potassium fertilizer is also indispensable.

Second, the main points of citrus acid deacidification and sweetening

1. After the end of the physiological fruit drop period, the tree body lacks fertilizer, potassium fertilizer can be applied appropriately, and the dosage of each fruit tree is catty. Note: Orchards with more vigorous trees or early autumn fertilizer can be omitted from this fertilization.

2. Sand sugar orange buried autumn fertilizer, the average yield of hanging fruit is 80 catties, for example, each plant: 5 catties of commercial organic fertilizer or fungus fertilizer or 10 catties of rotted farmhouse fertilizer + 1 kg of peanut bran + balanced compound fertilizer + medium and trace elements. Fertile mandarin buries autumn fertilizer, and the average yield of hanging fruit is 80 catties, for example, per plant:

8 kg of commercial organic fertilizer or bacterial fertilizer or 20 kg of rotted farmhouse fertilizer + 1 kg of peanut bran + kg of balanced compound fertilizer + kg of medium and trace elements.

3. About 15 days before the coloring period of citrus (sugar orange and mandarin orange), pour potassium dihydrogen phosphate once.

Okay, the above is all the content to share with you, generally speaking, if the citrus planted is sour, it is usually summarized for several reasons, you can pay attention to some sweetening points when fertilizing, I hope this article will help you.

In the north, there are apricot trees, jujube trees, apple trees, sea buckthorn, persimmon trees, and cherry trees. Hawthorn trees, fig trees. A large part of the reason for the acidic taste is that these fruit trees are prone to iron deficiency, because the soil in the north is mostly calcareous and contains high levels of calcium carbonate.

Citrus. It may be because you don't eat organic fertilizer, or it may be because of the lack of light, so the sugar content is very low, so it will be sour.

It is most likely caused by the lack of light in the plants. Only a lot of light time allows plants to photosynthesize well and promote sugar production. The fruit is sweeter.
