Every year around the Spring Festival, when it comes to the most popular large and medium-sized potted fruit plants on the market, it must be kumquat, kumquat is also of different species, many people do not know how to distinguish them, here is to give you science popularization, by the way to introduce maintenance techniques, including preventing fruit fall and promoting flowering in the coming year.
Above are kumquat, four seasons orange and cinnabar orange
Three different potted ornamental oranges:
1. Kumquat
Above is a kumquat (Citrofortunella microcarpa)
Kumquat (Citrofortunella microcarpa), also known as "golden jujube" or "crispy orange", it is a fruit plant of the genus Kumquat in the family Rubiaceae, its ornamentality is not as good as other ornamental oranges, because its fruit is relatively small, the shape of the whole fruit is oval, it looks more shiny, close to the smell of fresh fragrance, the peel is very crisp, sweet and sour, delicious, good taste.
The fruit ornamentation period of kumquat is relatively long, the ornamentality is relatively good, the fruit is edible, and it is a potted fruit with ornamental and edible value.
2. Four Seasons Orange (Short and Strong Type)
Above is the four seasons orange (Citrofortunella microcarpa)
Four seasons orange (Citrofortunella microcarpa) is a potted fruit belonging to the citrus genus of the family Rubiaceae, can maintain perennial emerald green, it can bloom many times a year, generally in June to September to conceive flowers, and then it will continue to bear fruit, the fruit is hung with branches, its fruit is flat and round, the whole form is relatively full, just like the oranges we buy in the market, the amount of fruit is rich, excellent ornamentality.
Oranges grow and blossom all year round, which is also the origin of its name, its taste is sweet and sour, the taste is general, there is a good ornament, so it is generally raised into small and medium-sized potted plants, suitable for raising on sunny balconies or window sills.
3. Cinnabar orange (thin and tall type)
Above is Citrus erythrosa
Citrus erythrosa is a fruit-viewing plant of the citrus genus in the family Rubiaceae, a particularly tall plant suitable for placement in doorways or living rooms. Its fruit, like the four seasons of oranges, is flat and round.
The fruit of cinnabar orange can also be edible, the taste is sour and sweet, and it is more common in Liangguang, Hunan and Fujian in China.
Why is the fruit easy to fall?
Many friends can not raise these potted ornamental oranges (including kumquats, four seasons oranges and cinnabar oranges), which is also no way to do things, because there is no way to provide a suitable environment for it, so their fruits are particularly easy to fall, after all the fruits fall, the leaves will gradually yellow and wilt, and finally the whole plant will dry up.
In fact, because of the lack of light, there is a full-day environment, the fruit is not easy to fall. Ensure sufficient light, coupled with sufficient moisture, there is a long viewing period.
So what is the way to keep these potted ornamental oranges blooming year after year, so that their leaves remain evergreen all year round?
It is a good choice to plant some potted ornamental oranges on the balcony or terrace, because they are not only very ornamental, their flowers are also very fresh, and the most important thing is that its flowers will have a very fresh fragrance, which smells particularly comfortable, just a little worse than the floral fragrance of lemon.
Usually, the potted ornamental oranges we buy in the flower market are planted with some older tile pots and clay pots, and some even use some plastic bowls.
If you think that the original pot is too ugly, you can directly put it in a better looking pot, once the pot is changed, it will cause the fruit to fall, and the viewing period will be shortened, because the roots are damaged.
This must remind everyone that if you want to change the pot in the later stage, you can only smash the original pot.
Precautions for the maintenance of potted ornamental oranges:
1. Give plenty of light
If you want to raise these ornamental oranges, you must try to have sufficient light, it is best to raise them in an environment with full sunshine, there are more than 8 hours of direct light every day, which has greater benefits for their growth, and must not be raised in the semi-shade, or excessive shade.
This is also why most friends can not raise these ornamental oranges an important reason, are because of the lack of light, it likes to be exposed, the more abundant sunlight it grows better, in the light is sufficient, but also remember to add water in time.
Many friends are the potted kumquat placed on the balcony or window sill, the light is certainly not enough, every day may only have 3 to 5 hours of soft light, it can not meet its growth needs, its fruit will slowly fall, but there will also be a longer viewing period, generally can maintain more than a month of viewing period.
After a month, the fruit of these potted ornamental oranges will continue to fall, the leaves will continue to yellow, the edges of the leaves will dry up, and then the leaves of the whole plant will continue to fall, causing the entire plant to wither, which is a very normal thing, and if you want to improve, you can only increase the light.
If the potted ornamental orange is raised in the indoor shade, it is just placed under the light, keep the light bright, or the environment is relatively dark, the fruit of the ornamental orange will continue to fall after 2 to 3 weeks, the leaves will continue to yellow and wither, and finally the entire plant will directly wither away.
2, the key to flowering and fruiting in the coming year
By providing as much light as possible to these potted ornamental oranges, you can keep the leaves emerald green all year round, and you can continue to raise them after the fruit falls, providing more fertilizer and water, and you can also flower and bear fruit in the summer and autumn of the following year.
This is also why the ornamental orange fruits placed in the outdoor open air can always be hung on the branches, and can still be seen after the Spring Festival, because the open-air environment is full of light.
To ensure sufficient light at the same time, must be timely to replenish water, whether it is its leaf surface, leaf back, or pot soil, to ensure that there is sufficient water, its demand for water is relatively large, ornamental orange fruit more, leaf growth dense, plus the pot is not particularly large, the demand for water is particularly large.
3. Pay attention to watering
When planting ornamental oranges in the open environment, it is basically to see that the topsoil is dry, and it is watered in time, if it is raised in the shade or semi-shade, it is basically dry under the soil surface of 3 to 5 cm, and then water it, which is the impact of the environment on watering.
Take care to maintain high air humidity
When watering potted ornamental oranges, do not use large water to rush, because these ornamental oranges are generally planted with vegetable garden soil, these soils are easy to clump, watering should be slow, can be watered many times, to ensure that watering, do not just water a little.
4. Supplement fertilizer
If you want to raise these potted ornamental oranges to re-bloom and bear fruit in the next year, you must ensure that there is sufficient fertilizer, many friends potted kumquat fruit fall, you can keep the leaves emerald green, but there is no way to flower and bear fruit, it is because of the lack of fertilizer.
After all its fruits have fallen, it is necessary to add some nitrogen fertilizer to promote the growth of branches and leaves, so that its leaves grow more luxuriantly. All kinds of water-soluble fertilizers with more nitrogen content on the market can be used, no matter which brand can be used, about 10 days to use once.
In the summer and autumn, when it is ready to gestate flower buds, it can begin to supplement the potassium dihydrogen phosphate solution, and it can also be used with other fertilizers with higher phosphorus and potassium content, which is used every 7 to 10 days. For example, it is sprayed alternately with Huaduoduo No. 2 and potassium dihydrogen phosphate solution, and other general-purpose flower-promoting fertilizers.
When spraying potassium dihydrogen phosphate, it is necessary to pay attention to the uniform spraying of the leaf surface back, which can promote the normal development of flower buds.
During its fruiting period, it should also pay attention to regular spraying of potassium dihydrogen phosphate, or other potassium fertilizer, to make its fruit full.
Do the above points, these potted ornamental oranges can achieve annual flowering and fruiting, of course, once the diseases and insect pests are found, they should be treated in time to keep the soil slightly acidic.
After the fruit falls, regularly add some decomposed sheep manure to the soil, grind it into a powder and sprinkle it on the soil surface, water it thoroughly, and let the fertility slowly penetrate, which helps to improve the fertility of the soil and ensure that the soil is acidic.
