Is the cultivation of sweet oranges the same as the cultivation of citrus

1 Mandarin orange is a citrus fruit, which is different from tangerines and oranges.

Mandarin orange, also known as mandarin fruit, is a common fruit in daily life, but it is neither an orange nor an orange. Generally speaking, there are seeds in the flesh of the citrus, and the fruit is large, bright in color, and looks like a ball, and the peel is pine. The peel is yellow or orange.

After eating, the taste is very sweet, and the meat is crisp and tender. Long storage time.

2 Mandarin orange is a fruit made by crossing tangerines and oranges.

In fact, many citrus fruits are cross-bred, and oranges and grapefruit are crossed to form oranges; Grapefruit and orange were crossed to form lime; Tangerines and oranges were crossed to form mandarins; Oranges and grapefruit were crossed to form grapefruit; Oranges and limes are crossed to form lemons. Citrus is rich in cellulose, pectin, organic acids, water, etc., all of which help maintain satiety and improve digestion. It is also a common and cheap fruit, and eating 1 citrus can basically meet a day's vitamin C needs.

3. Eat in moderation will not.

Mandarin orange is a fruit in autumn and winter, now is the season to eat orange, and its nutritional value is also very rich, but orange should be eaten in moderation. Mandarin oranges are rich in vitamin C, and at the same time rich in sugar, because citrus contains fruit acid, which can promote the absorption of sugar and produce more calories, so eating too much will also make you fat, but as long as you control the amount of citrus you eat, there will be no problem of gaining weight.

It depends on its variety, planting technology, management, soil and other ridges, those citrus planting areas, there will be special technicians and skilled personnel, Morino key to teach technology and experience, I don't know if you have special technical personnel there, you can go to consult!!

Sweetening and coloring is an extremely important process in the growth and development of citrus, which is related to the appearance quality and flavor quality of citrus, and directly affects consumers' desire to buy and the best of the fruit.

1. Improve lighting.

8 November is the period when light has the greatest impact on the quality of citrus fruits, and if the fruit trees do not have enough light at this time, it is easy to lead to low juice, low sugar content and poor color. Therefore, we should take improving the ventilation and light transmission conditions of fruit trees as the starting point, strengthen canopy management, and prune reasonably to achieve the purpose of promoting the sweetening and coloring of citrus. We must achieve "dense to thin, high to low", to ensure the formation of "independent trees, independent branches", that is, to appropriately adjust the distance between trees and between branches, so that they do not intersect and overlap.

The specific criterion is to maintain a distance of at least 30 to 40 cm between the two canopies, and the height of the canopy is not higher than the permeable meter. Fruit farmers who plant densely in the orchard can take the method of thinning or transplanting, and try to keep the plant row spacing at about 4*3 meters to avoid the orchard canopy.

2. Reasonable fertilization.

After citrus enters the flavor formation period, we should also pay attention to nitrogen control, phosphorus and potassium and medium and trace elements in fertilization. This is because nitrogen promotes vegetative growth in fruit trees and hinders the transfer of sugar to the fruit. Phosphorus can improve photosynthetic energy efficiency and promote fruit ripening, and potassium can increase fruit sugar accumulation and promote coloring. The trace element molybdenum can promote the synthesis of organic phosphorus-containing compounds in plants, participate in photosynthesis and respiration in the body, and promote fruit sweetening and coloring.

1. Increase calcium fertilizer 2, spray foliar fertilizer 3, and apply basal fertilizer early.

3. Water management.

During the expansion of citrus fruits, fruit trees often need a lot of water**, at this stage, fruit farmers must do a good job in the water management of the orchard, drainage after rain, watering during drought, and keeping the orchard soil moist at all times. Now in September, many citrus producing areas have rainy days, and everyone should pay attention to drainage and waterlogging in the orchard to avoid abnormal yellowing and fruit drop of citrus fruits.

When the fruit is ripe and ripe, the appropriate water stress is conducive to fruit coloring. Therefore, we should pay attention to keeping the soil in the orchard dry at this time to reduce the nitrogen uptake by the fruit trees. Because nitrogen will speed up the growth of fruit tree branches, the fruit will not be able to absorb enough nutrients to maintain its sweetening and coloring, which is a typical tip fruit contradiction.

In addition, scientific water control can also improve the soluble solids and sugar content in the fruit juice, and improve the quality of the fruit.

May everyone's efforts on the road to citrus cultivation be richly rewarded!

Nutritional value of citrus.

Sexual taste is attributed to the meridians: cool in nature, sweet and sour in taste; into the spleen, stomach, and bladder meridians. It has the effect of quenching thirst and stomach diuretic; Because the juice of mandarin orange can clear the stomach and heat, it can be used as a nourishing therapeutic fruit for those who have diaphragm irritation, thirst in the mouth or alcohol poison and heat, lack of food and qi reversal, and unfavorable urination.

The taste of mandarin orange is fragrant and sweet, and there is a feeling of sweet and thick honey after eating, and the flavor is unique, and it is well-known at home and abroad. The edible part of the citrus fruit can reach 68%-75%, the soluble solids content is 12%-15%, and the sugar content per 100 ml of juice is 11-13 grams, acid grams, vitamin C 25-35 mg, and the quality is particularly good. The edible part of 100 grams of citrus fruit contains calorie joules, water grams, protein grams, fat grams, sugar grams, fiber grams, ash grams, calcium 25 mg, phosphorus 19 mg, iron mg, vitamin A140tu, vitamin mg, vitamin mg, vitamin C 40 mg, niacin mg.

A large number of vitamins and minerals can improve human health and are indispensable substances for human tissues; Pectin can reduce cholesterol in the blood; In addition, regular consumption of citrus fruits can also decompose fat and excrete harmful heavy metals and radioactive elements accumulated in the body.

Mandarin orange has a variety of effects such as regulating qi and strengthening the stomach, drying and dampness and dissolving phlegm, relieving asthma, dispersing knots and relieving pain, promoting appetite, sobering up and antimalaria.

Nutritional value of oranges.

Orange has the effects of widening the intestine, regulating qi, dissolving phlegm, eliminating appetite, appetizing, relieving nausea, relieving pain, relieving cough, etc., and can be used for chest tightness, abdominal distention, vomiting, constipation, poor urination, hemorrhoidal bleeding, hangover, fish, crab poison, etc.

Oranges are rich in a variety of organic acids and vitamins, which can regulate the body's metabolism, especially for the elderly and patients with cardiovascular diseases.

Orange peel contains fruit acids, which promote appetite and help digestion for people with low stomach acid.

The fiber in oranges helps with laxatives and lowers cholesterol. Oranges are rich in vitamin C, which has anti-cancer effects. [7]

Orange beauty method: take 1 fresh orange, wash and peel, slice, remove the orange seeds and apply it to the face, once a day, 20 minutes each time, you can remove the facial pigment, **tawny brown [3].

Food.

Oranges should not be eaten with betel nut. [8]

Every autumn and winter, the fruit market from all over the world is really rich! Oranges, bananas, and grapefruit in the south, apples, pears, and persimmons in the north ......They have their own characteristics, they are sweet and delicious, and they are interesting to choose from. Take oranges, for example, it's dazzling enough to see:

What Huangyan early orange, Nanfeng mandarin, Sichuan Jincheng, Guangdong Xinhui orange, as well as banana orange, snow mandarin, reed mandarin and so on. Why are they all oranges, but some are called oranges, some are called oranges, and some are called oranges? How exactly can they be distinguished?

It turns out that these good names of oranges are not arbitrarily given by people, they are all scientifically named by botanists and pomologists according to the distance of the plant. Citrus has many sisters, and in addition to the above, lemons and grapefruit also belong to this genus, but they are easier to distinguish than citrus.

In fact, when we eat oranges, if we pay a little attention, oranges, mandarins, and oranges are not indistinguishable.

Some oranges have very wide and loose skins that are easy to peel off, while some have lighter skins and tightly wrapped capsule flaps, which are not easy to peel off. An orange that is not easy to peel is an orange. Orange is divided into two categories: sweet and sour, the sour one is called lime, which cannot be eaten, and is mostly used as a rootstock; The sweet one is called sweet orange, the flavor is excellent, and it is the top grade of orange, such as navel orange, Xinhui orange, golden orange, etc.

Another distinctive feature of orange is that the seeds are large, and the embryos inside the seeds are white. If you compare the morphology of fruit trees, the leaves of sweet oranges are larger than those of citrus, and the base of the leaves also has wing leaves, while oranges and mandarins generally do not have this characteristic.

Oranges with wide skins and easy peeling are also known as wide-skinned oranges. It is widely cultivated in our country. They have thinner skins and large cysts that can be broken open with one petal, while sweet orange capsules are difficult to separate. When the seed coat of citrus and orange is removed, the green embryo can be seen.

The more confusing ones are citrus and tangerine. Because they belong to the broad-skinned citrus family, they have similar characteristics to each other. Although their skins are easy to peel, mandarins are slightly more difficult, while mandarins are extremely easy.

The spongy layer of the peel is also thicker than that of mandarin. Wenzhou mandarin oranges, banana mandarins, etc. are all mandarins, while early oranges, Fu mandarins, and Nanfeng mandarins are all oranges.

However, due to the different names of the people in different places, there is often confusion in the name. For example, some places call Wenzhou mandarin orange seedless; Sichuan's golden orange, because of its long round fruit shape, is also called goose egg orange in the local area. In this way, the confusion of the name of the orange has led to the confusion of people's concepts.

"orange" (jú) and "桔" (jié) are both standard characters in modern Chinese. Due to the homonym of the two characters in some dialects of Guangdong, and the fact that "orange" has been used as a simplified word for "orange", the mainland has adopted "orange" as a popular way to write "orange". Taiwanese call tangerine orange as mandarin orange.

In the dialects of the Southwest Mandarin District, it is called "mandarin" or "mandarin".

Mandarins, oranges, oranges and grapefruit are three different varieties of citrus fruits, which can be easily confused due to their similar appearance. Citrus is a general term for mandarin, mandarin, orange, kumquat, pomelo, citrus, etc., and the names of mandarin and tangerine have long been confusing.

From a scientific point of view, orange is the basic species, with small flowers, easy peel, and dark green seeds. Mandarin orange is a hybrid of orange and sweet orange and other citrus, the flowers are large, the fruit is not as easy to peel as orange, and the embryo of the seed is pale green. Therefore, in wide-skinned citrus, orange mandarin (Lu mandarin) is an orange not an orange, and Wenzhou dense orange is an orange not an orange.

Citrus and tangerines are woody plants of the same family and genus but different species in plant taxonomy. In addition, citrus and tangerine are often referred to collectively as citrus. Citrus plants are the most dominant group of citrus fruit trees, it has 17 species divided into 6 groups:

Big-winged oranges, Yichang oranges, citrus lemons, pomelo, oranges, and broad-peeled oranges. Citrus fruits include a large family of oranges, mandarins, pomelo, citrons, sweet oranges, limes, kumquats, and lemons. Excerpt from.

To be honest, I can hardly tell the difference between oranges, tangerines, and mandarins, and they are all called by feeling. When I arrived at the big supermarket, I was even more dazzled and stupid when I looked at all kinds of fruits.

Different citrus species and varieties can not be mixed planting, its critical low temperature is different, so the geographical landform required by each variety is different, Chang orange, kumquat, Wenzhou mandarin, sweet orange, lemon critical low temperature is -15, -10, -9, -7, -3 degrees respectively.

The area of 120-150 mm per month during the citrus growing season is suitable for the cultivation of citrus. The annual precipitation of Nanpanjiang in Yunnan Province is only 700 mm, and there is also a large area of citrus cultivation, mainly using irrigation water supply.

Citrus is a high-yielding fruit tree that requires strict soil conditions.

1) Citrus requires neutral acidic soil, pH, but appropriate. There are places where masson pine, tea, rhododendron, etc. grow, which belong to the acidic soil, and citrus orchards can be established. Soil alkaline soil needs to be improved before cultivation.

2) Citrus is a deep-rooted fruit tree that requires a soil depth of at least one meter. If the soil in the mountain is thin, it is necessary to dig deep and cultivate the soil to increase the thickness of the soil layer in order to make the root system developed and the aboveground part lush.

3) Citrus roots require loose, aerated and well-drained soil, and loam soil is the most suitable.

4) The soil organic content reaches more than 2%, which is conducive to the growth and development of citrus.

5) The quality of soil conditions is not only related to the yield of citrus, but also directly affects the quality of fruits. According to research, orchards with loose soil and rich organic matter content have deep skin coloring, low acid content, strong flavor and good quality.

The extreme low temperature in Xinjiang exceeds the low temperature tolerance limit of orange trees, and orange trees cannot be cultivated. Unless it is a facility cultivation.

Mandarins and oranges are not the same plant at all, and there is a huge difference between their seedlings.

1. Citrus orange, also known as citrus fruit. Brightly colored, sweet and sour, it is one of the most common fruits in daily life. The citrus fruit is generally larger, but smaller than the pomelo, round and slightly flattened, the skin is thicker, convex and concave rough, the peel is easier to peel, and its seeds are mostly white.

The fruit of the citrus is huge, the color is bright, the skin is loose and easy to peel, the flesh is crisp and tender, and the juice is more slag.

2. Orange (scientific name: citrus sinensis) is the fruit of the citrus plant of the family Rutaceae, also known as yellow fruit, citrus, golden ring, willow ding. Orange is a citrus fruit, a hybrid of citrus (citrus maxima) and tangerine (citrus reticulata) that originated in Southeast Asia.

The fruit can be peeled and eaten fresh, and the pulp can also be used as an add-on to other foods. Another important use of the fruit is for juice extraction.
