When do tangerines ripen

Nowadays, with the increasing development of high technology, many fruits and vegetables sold on the market violate the law of seasonality. Although they can meet people's needs at any time, they may cause changes in taste or loss of nutrition. Now we will mainly use tangerines as an example. So, friends who like to eat tangerines, do you know when they are ripe? Would you buy them if they are not in season?

Although you can buy tangerines whenever you want nowadays, there is still a difference if the fruit is produced against the laws of nature and relying on artificial technology. So, when is the best time to eat tangerines? When is the time when tangerines naturally ripen?

Analysis and countermeasures of mandarin orange's habits

1. Flower bud differentiation period (from the first to the twenty-fifth day of the ninth lunar month)

The main function of this period is to determine the output for the next year. During this period, citrus trees develop buds and fruit embryos for the next year.

2. Bud budding and flowering period (after the spring equinox to before Qingming Festival)

The buds and small fruit embryos that sprouted in September of the lunar calendar last year begin to grow during this period, and the buds become tender leaves; the small fruit embryos then develop into real embryos, just like a newly formed infant in the mother's body. Do not use pesticides during this period.

3. Fruit setting and stress resistance period (April 20-May 20)

This period is a critical period for citrus fruit setting, disease and pest control, and determines the annual yield.

4. Fruit growth and sugar increase period (June 25-July 25)

This period is when citrus evolves from youth to adulthood. The fruit that sets in May goes through 30-60 days of development, completing the entire process from infancy to adulthood. This period is a period of high temperature and low humidity for citrus. The transpiration of citrus is accelerated, and a large amount of water and nutrients are lost rapidly with transpiration. At this time, citrus needs a lot of nutrients and water to complete its maturity and sugar content.

Laboratory research has concluded that the nutritional requirement during this period is 28% of the total nutrition of citrus in a season. However, under our traditional planting habits, we do not fertilize citrus, but instead use pesticides to increase the nutritional consumption of citrus. I am not saying not to use pesticides, because this period is also the peak period for diseases and insect pests, especially scab, water rust, whitefly, mustard bark, carbon maggot disease, etc.; but I am saying that you should use fertilizer to ensure the growth conditions when applying pesticides.

Medicinal value of tangerine

Eating oranges regularly can not only supplement the body with a variety of vitamins and inorganic salts and other nutrients, which has the effect of strengthening the body and promoting growth and development, but also can strengthen the stomach, aid digestion, dry dampness and eliminate bloating. It is an effective treatment for indigestion, spleen deficiency and abdominal distension, qi stagnation, and chest fullness. A good remedy for excessive drinking and can also stop malaria attacks.

Taboos on eating tangerines

Eat radish together

Oranges are a fruit that people often eat in autumn, winter and spring. Orange is a treasure from head to toe and is the best among fruits. Because it is sweet and sour, juicy, moderately soft and hard, easy to peel and eat, and has the effect of relieving cough, it is loved by men, women, young and old.

However, after eating oranges, the flavonoids they contain can be broken down and converted into hydroxybenzoic acid and ferulic acid in the intestines. These substances have a strong inhibitory effect on the thyroid gland. If you eat radish at the same time, the thiocyanate contained in radish will further enhance the inhibitory effect on the thyroid gland and cause enlargement of the thyroid gland.

Eat pork liver

Vitamin C is an enol structure substance and is easily destroyed by oxidation. Especially when encountering trace amounts of metal ions, the rate of oxidation will accelerate by about a thousand times. Pork liver is rich in copper and iron. If eaten with oranges, the copper and iron in the liver will quickly oxidize and decompose vitamin C, causing the vitamin to lose its original function.

When vitamin C is deficient, the body's collagen decreases and capillary fragility increases. In addition, bleeding may occur in the gums, mucous membranes, subcutaneous muscles and joints. You must make scientific meal combinations in your diet to get more nutrition from it.

The growth of any vegetable or fruit requires a certain amount of time and needs to conform to the laws of nature, so as to ensure the taste and nutrition of the vegetables or fruits. Mandarin oranges also need to go through four stages: bud stage, flowering stage, fruit setting and stress resistance stage, fruit strengthening stage, and sugar increase stage. Although this process is long, it conforms to the laws of nature and the resulting fruits are the most satisfying to people. It can be seen from this that June and July are the ripening period of mandarin oranges, and July and August are the most suitable seasons for eating mandarin oranges.
