Why don t oranges have seeds? Why don t orange seeds bear fruit when planted?

In general, there should be seeds. If you can't eat it, that's your problem.

There are also those that do not have seeds, and there are generally two ways, one is to artificially breed those that do not produce seeds.

The second is to avoid pollen from reaching the stigma, which naturally does not produce seeds, but there is another problem, that is, it does not bear fruit. Because pollen has hormones on it that make the ovary of the flower grow fruitful. So give it some hormones, and it will grow seedless fruit.

This is convenient, but when it comes to hormones, there are people who dare not eat it.

Then it is estimated that the orange you eat is the one without seeds, and the orange eats the kind with seeds. It is estimated that it is the seeds of oranges that make people who eat them very unhappy, so there are more oranges without seeds. And people don't mind that oranges have seeds in them, so people don't bother to bother with it, so oranges mostly have seeds.

The reason is probably this, because I have indeed always eaten oranges without seeds (I have eaten them with seeds before) and I have never eaten oranges without seeds (it seems that no one has studied this, and the benefits are too few.)

He is a hybrid fruit, just like a mule born from a donkey and a horse is infertile, and the same is true for fruits, a hybrid that is infertile and has no seeds.

Wait 3-8 years for results

Orange seedlings grown from seeds are solid seedlings, and they take 3-5 years to bear fruit as fast as they are fast and 5-8 years as slow as they are slow. For it to bear fruit early, keep their surroundings between 16-22. Usually ventilate it more often, and let it receive more scattered light.

During the growing season, fertilizer should be applied in time to provide nutrients and help it grow and bear fruit.

The time is not up. If we plant orange seeds directly, the growth rate is relatively slow, if you want it to bear fruit, you need to maintain it for 3 to 5 years, and sometimes you may need to feed it for about 8 years, and it is generally planted more in the south, because the climatic conditions in the south are very suitable for the growth of oranges.

If it is planted in the north, it may not bear fruit, because the temperature in the north is relatively low, even if it bears fruit, the time may be longer, and most people will plant small seedlings directly when planting orange trees, or they will be planted by grafting, so that the fruiting time will be shorter.

Can be planted. Specific steps:

1. Clean the orange seeds and remove the flesh on the surface.

2. After removing the pulp, soak the orange seeds in clean water, change the water once a day, and soak for a week.

3. Take out the seeds and use tweezers to remove the thin skin on the surface of the orange seeds, and be very careful.

4. Prepare a pot of nutrient soil, bury the orange seeds in about two centimeters under the soil, and then water them every day.

Extended information: 1. The planted orange seeds germinate in about 3 weeks, and the weather should be warm and suitable.

2. When planting in cold weather, the germination time will be later.

You can't eat it, orange seeds can't be digested in the stomach, and eating too much will lead to flatulence. Many people always like to bite into fruits and swallow them when they chew them, regardless of whether they have seeds and pits; Some people think that fruit seeds contain nutrients and should not be wasted from the perspective of nutrition, so they eat them directly, but in fact, this behavior is very dangerous.

Chen Shiqi, deputy director of the Department of Gastroenterology of the Second People's Hospital of Yulin City, pointed out that watermelon seeds, grape seeds, cherry pits, apple cores, and occasional small amounts of accidental ingestion are not related; However, if you eat fruit seeds for the sake of health care and other effects, not only will it have much effect, but some will even affect your health.

Hello, take seedless sugar orange as an example. Planting technology 1, soil: sugar orange has a wide range of soil adaptation, but the soil is loose, the structure is good, the organic matter content is 2% 3%, and the soil with good drainage is the best, and the pH value is the best.

2. Planting: Choose seedlings with a height of about 50 cm, developed root system, and no diseases and pests, and cultivate them according to the specifications of 80 plants per mu of 10 7 feet, 100 plants per mu of 10 6 feet or 110 plants per mu of 9 6 feet. Zheng Bian disturbed 3, fertilizer water:

Nitrogen fertilizer is the main fertilization of young trees, with phosphorus and potassium fertilizer, and fertilization is applied 5 6 times in spring, summer and autumn shoot extraction period, and each plant is fertilized with ammonium carbonate or urea. Adult trees are fertilized with germination fertilizer, fruit preservation fertilizer, strong fruit fertilizer, and fruit picking fertilizer. Water when the soil is dry and drain when it is waterlogged.

4. Pruning: The young tree is mainly lightly pruned, and the long branches of the main branch and the secondary main branch are cut short, and the dense branches are pruned. At the initial fruiting stage, the trunk extension branches at all levels were truncated, and the summer shoots were erased.

At the peak fruit stage, the fruiting branch group, the flower-falling fruiting branch group and the declining branch group were retracted, and the light-blocking branches, dead branches, diseased and insect branches were pruned. 5. Diseases and insects: diseases include anthracnose, foot rot, etc., and insect pests include mites, scales, aphids, leaf miners, longhorn beetles, flower bud maggots, etc., which should be prevented and controlled in time.

There are the following reasons why only flowering does not bear fruit:

1) Natural disasters, frost damage during or before flowering.

2) Malnutrition, incomplete development of flower buds, resulting in degeneration of pistils.

The following measures can be taken to promote the results:

Prune reasonably and regulate the tree's potential. The main reason for the failure of orange trees to grow vigorously is that they are overly pruned, resulting in overgrowth. Therefore, take a light cut and slow release on the pruning.

Except for the cultivation of the main and side branches according to the shaping requirements, and the sparse individual densely packed branches, the rest of the branches are all retained and thrown. The angle of the main branch is increased to 60 70° in winter and 80 90° in the auxiliary branch by pulling the branch in winter, twisting and plucking the branch in summer. In the growing season, when the top shoots on the back are about 20 cm long, the topping is carried out to promote branching.

Ring stripping of larger main and auxiliary branches. Ring stripping is carried out at noon on a sunny day, and the width of the peeling is generally 1 8 of the branch diameter.

Control fertilizer and water, slow down and promote flowering. In addition to two irrigation before freezing and germination, as long as the leaves do not wilt, do not irrigate, and drain water in time in the rainy season. In order to prevent vigorous growth and promote flower bud differentiation, fertilization should avoid the flourishing period of new shoots, top dressing after the growth of new shoots, apply more in autumn shoots for a long period (from the end of August to early September), and apply less in spring shoots for a long period (early to mid-June), and increase the amount of phosphorus and potassium fertilizers and reduce the amount of nitrogen fertilizers.

Generally, 80 kg of soil miscellaneous fertilizer is applied per plant in late September, 1 kg of urea per plant is applied in early June, and 1 kg of nitrogen, phosphorus and potassium compound fertilizer is applied in late August. From the spring, combined with pest control spraying urea and potassium dihydrogen phosphate, spray once every 10 days or so, 3 5 times each. In addition, the spraying of borax once and artificial pollination during the flowering period of plum trees had a significant effect on improving the fruit setting rate.

Here's why:

1. Fertilizer and water management is excessive.

2 Too little light.

Want to buy some greenery for your new home, something like that. Which god knows that this is a god horse flower? Phalaenopsis?

There is this name. Does anyone know what kind of orchid it is? Almighty Weibo, please tell me what kind of flower is this??

The orange trees that were transplanted at the end of last year began to grow new branches in April, and now the newly grown leaves are starting to wilt little by little, what is going on? Ask for advice.

Last year, there was too much fruit hanging and it hurt the foundation. It will bear fruit next year.

The reasons for the failure are as follows:1. The vitality of orange seeds is fragile and difficult to survive.

2. The planting time is not enough, and it generally takes 3-5 years or 5-8 years for the fiber burning skin to bear fruit.

3. The maintenance environment is not suitable, and temperature, light, ventilation, fertilization, etc. will affect the results.

1. Remove the surface pulp of the seeds, rinse them with water, and then soak them in water for about a week, changing the water once a day.

2. After soaking for a week, remove the thin skin on the surface of the seeds with tweezers, taking care not to hurt the inside.

3. The peeled seeds are placed in a ventilated place to dry, and then gently buried in a soft, breathable nutrient soil pot, head up, with a depth of about 2 cm.
