Why can t Jianlan bloom when it grows flower buds?

The reasons why orchids do not bloom are common, such as too little light, which is the reason why most orchids do not bloom, and sunlight is the most important nutrient for orchids**; In summer, there are flower buds but they do not bloom because of the hot weather and poor ventilation. The lack of flowering in autumn and winter is due to a long period of dryness, which leads to dehydration of the plant and the cessation of flower bud differentiation; Sometimes everything is normal, but the flower buds suddenly stop differentiating after the flower stalk is drawn, that is, the flowering season is not right, the light, temperature, and humidity are not right, and the flower buds will also stop differentiating.

To promote the flowering of orchids, we should pay attention to the following aspects:

1. Light and light are the main factors that promote the cultivation of flower buds in orchid plants. Generally, orchids need to be exposed to light for 2 to 3 hours, and the leaves are soft and moderately green, indicating that the light is normal; The leaves are dark green and soft, indicating the need for increased light; The leaves are yellowish, indicating that the light should be reduced.

Second, the temperature to promote the flowering of orchids, it is necessary to make the difference between day and night temperature about 10, that is, 18 21 during the day, 7 10 at night under the temperature conditions of the best growth, more flowering. High temperatures at night can cause orchid leaves to soften and flower buds to fall off. Temperatures that are too low can cause blind buds and spots on the leaves.

When flowering, the flowers are affected by low temperatures, and the flowers will appear brown spots.

3. Watering, the amount of watering is also the main condition for orchid flowering, and the water should be controlled. If there is a lot of water, the orchid plant will grow and it will not be easy to grow flower buds.

As long as the usual maintenance and management is strengthened, the plants grow bigger, stronger and longer, and special attention is paid to increasing the light and adding chlorphosphine and potassium fertilizer before and after the differentiation of flower buds, it is expected to bloom.

1. Lack of time.

1. Reason: Orchids have a characteristic, that is, most varieties take a long time from budding to flowering, and many varieties take several months. If the orchid does not bud for a long time and is growing well, then the reason for not flowering may be a lack of time.

2. Treatment method: At this time, no special treatment is required, and it can be maintained in an environment between 15-20. After waiting for a while, it will be able to bloom smoothly.

2. Overwatering.

1. Reason: After the orchid grows buds, it needs to be controlled and maintained. At this point, if it is overwatered, it will cause damage to its root system. If the condition is severe, it will also cause its flower buds to wilt and fail to bloom.

2. Treatment method: At this time, watering should be suspended for a period of time. If the buds of the orchid have withered, they also need to be cut off in time. Wait until the soil is dry, then water again.

3. There is no vernalization.

1. Reason: Some varieties of orchids, such as cold orchids and spring orchids, need to be vernalized to bloom smoothly. If vernalization is not carried out at the time of cultivation, then it may not be able to bloom properly.

2. Treatment method: Before the orchid that needs to be vernalized enters the flowering period, it should be placed in an environment of about 10 years and maintained for about 1 month. In this way, when it is in flowering, it will be able to bloom normally.

Fourth, lack of nutrients.

Generally, the differentiation of flower buds is enough to indicate that the nutrients are sufficient, and there is no need to continue to fertilize, just spray the foliar water-soluble fertilizer. The so-called flowering period should pay attention to fertilizer and water management, so as to promote the expansion of flower buds, that is, pay attention to foliar top dressing. You can choose the special organic nutrient solution for orchids, and spray foliar fertilizer once in about half a month to promote flowering.

However, it should be noted that when fertilizing, do not spray the flower buds, which will cause bud loss.

The reason why Jianlan does not bloom.

It blooms in June in the summer and can bloom until October, usually twice a year, with a one-day flowering period and an ornamental period of about five months.

If the soil quality is not good, lack of nutrients, insufficient light, poor ventilation, unsuitable temperature and other reasons will affect its flowering.

Jianlan only grows leaves and does not bloom.

Improper light: Jianlan likes shade, and it is best to put it in a cool environment during maintenance, but in this environment, the flower buds of Jianlan will not differentiate, so it will only grow leaves and not flower.

Improper watering: Jianlan likes a moist growing environment, and needs to be kept hydrated during the maintenance period, if it is not watered for a long time, Jianlan will grow and not bloom.

What to do if Jianlan doesn't bloom.

Jianlan should apply more phosphorus and potassium fertilizer during the flowering period, spray the foliage with potassium dihydrogen phosphate, and at the same time have sufficient light and reduce watering, so that it can bloom.

Jianlan planting is a flowering method.

1. Potting soil: Buy Jianlan at home, whether you take it with a basin or not, in order to better adapt to the new environment, it is best to change the potting soil. Jianlan plants are erect and have thick roots, so it is more suitable to choose a tall sand pot, not only because of good air permeability, but also because of the temperament of flowers.

2. Thin fertilizer diligent application: Jianlan is a fertilizer-loving flower, which can use microbial organic nutrient solution, which is rich in nutrients, and is used once in the half month before and after flowering.

3. Control watering: Jianlan fleshy roots can not be watered too much, each watering is dry, watering is thorough, watering is thorough, avoid watering in rainy days. In summer, you can spray more water mist on the leaves to increase air humidity and avoid the leaf tips from drying out and yellowing.

The first point is improper fertilization, no matter what plant wants to flower, it is inseparable from phosphorus fertilizer, phosphorus fertilizer can promote it to differentiate flower buds, complete the flower bud differentiation to make it grow taller, and then unearthed directly flowering, we raise orchids as well, we must remember that if you want to make it bloom, before it blooms, use phosphorus and potassium fertilizer in advance to make it bloom, if you use nitrogen fertilizer for a long time, nitrogen fertilizer has long branches and leaves, it is impossible to grow flower buds, Using it for a long time will only make your orchid grow and the seedlings will not bloom.

The second point is that the light is unreasonable, although most of the orchid varieties like strong light, although there are those who like weak light, but light is essential, especially in the stage of its flower bud differentiation, if you put it in a dark place, it can grow leaves and buds, but it is very likely not to bloom, because it has no light, it can not bloom.

Many times the leaves of orchids have grown luxuriantly, but they just don't bloom. In fact, it's not that you don't take good care of it, but that the way to raise flowers is wrong.

1. Fertilization. Orchid fertilization should be done thinly and frequently, spraying organic nutrient solution on its leaves in the morning or dusk, which is rich in nitrogen, phosphorus and potassium. Try to dilute it, don't be afraid of being too thin, just afraid of being too strong, you can mix it with water 1000 times, and use it once every 2 weeks. Be sure to water the orchid before fertilizing, and you can fertilize it when the orchid leaves don't drip.

2. Pay attention to environmental changes.

Although orchids are not very demanding on the environment, they are very sensitive to changes in the environment. The slightest change will affect its growth. So don't move it around, don't pick it up and look left and right.

3. Defloration. For orchids with poor growth, there are not many leaves per bush, or the roots are not good, they should be picked. For better varieties, Chunlan can appropriately remove 1-2 flower buds, Xia Lan to leave 1-2 flower buds when the flower buds are elongated, and the rest can be removed, so that the flowers can bloom longer, and the new leaves can be pumped more, and the old leaves are not easy to die.

First, the solution.

1. Appropriate amount of watering: After budding, the requirements for water are strict, and it cannot be dry and low, and the drought and flood are uneven, otherwise the water of the mother plant will not keep up, which will affect the growth of new shoots. It is best to place it in a high place suspended in the air to facilitate drainage and keep the soil moist later.

2. Reduce fertilization: There is no need to over-fertilize during this period, and you can even stop fertilizing acacia jujubes. It is necessary to wait for the small buds to open the orange mouth before applying, otherwise not only will they not be absorbed, but it may also affect the growth of the new shoots.

It is best to apply a special nutrient solution or a diluted fertilizer when fertilizing, so that the roots can grow more robustly and thus promote the growth of new shoots.

3. Can't move: If you see the buds after seeing the sprouts and repeatedly move or turn the soil, it will affect its growth, and even zombie buds will occur. Therefore, it is best not to move too often at this time to avoid affecting the growth due to unsuitable light and humidity.

Second, the strong sprout of galena.

If you want the orchid to produce stronger buds, you can add aspirin tablets to the water when watering, which can improve its immunity and germination rate, and also facilitate the growth of new roots. In addition, you can also dilute vitamin B12 with water to spray the leaves, which can not only enhance immunity, but also have the effect of rooting and promoting germination, and the flowers will be more beautiful.

It is clear that this orchid has survived and its root system is not growing badly, but why hasn't it germinated until now?

After pouring the pot, I saw that it had a bud point at the head of the reed, and it had taken shape and sprouted new roots from the bud point. In fact, if this pot of orchids is not touched, the sprouts will emerge robustly by next spring, and they will grow into strong grass next year.

Under the same conservation environment, planting materials and management methods, the buds of this orchid appeared the latest, what is the reason? Without practice, there is no right to speak, and it is impossible to know the truth without a complete understanding of the context. I carefully looked at the relationship between the seedlings, roots and shoots of this orchid, and came up with some personal opinions, hoping to inspire orchid friends.

Reasons for not germinating.

Because there is only one seedling left in this orchid when it is potted, and it is a new seedling of the year, its reed head does not have the ability to tiller new seedlings. In the period between this spring and now (September to be exact), all it can do is to drain as much energy as possible from the old reeds, and then desperately grow new roots to sustain itself. In fact, it is doing the same, and it can be seen from the figure that the new root system is relatively sound, which is the result of most of this year.

When its new roots are sound, it can draw more nutrients from the soil, and the reeds of the seedlings are gradually maturing. At this time, there is the ability to tiller new seedlings, so they sprout in September. The bud point we see now also has a growth period of at least two months or more, which is more common in weak seedlings planted in autumn.

Through the above example, it can be seen that there is a relationship between old seedlings and new shoots. In fact, Lan You can contact one of my previous articles, which is about the question of whether to cut off the old seedlings before planting the Xiashan orchid.

The role of old leaves.

The really good-looking leaf type is the domesticated seedling after two years of raising. But don't underestimate those unsightly old orchid leaves, their role can be great, if you cut it off as soon as you get started, it will have a great impact on the survival and rejuvenation of the whole orchid.

Orchid leaves can produce nutrients through breathing and absorb water through breathing during the potting period after orchid planting, and the orchid roots are still in a state of suspension at this time, that is to say, the old orchid leaves assume the responsibility of the nutrients of the orchid plant. If the old orchid leaves are cut too early, it will cause the orchid plant to be potted slowly and the new shoots to develop stunted.

When the domesticated seedlings are not yet perfect, we spray foliar fertilizer and fungicides, all of which need old leaves to absorb and transmit to the orchid plant. At this time, the effective receiving area of the leaf directly affects the absorption and utilization rate of medicine and fertilizer.

In the same way, photosynthesis is an important condition for the healthy growth of orchid plants, the first element of photosynthetic efficiency is the light-receiving area of orchid leaves, in the same environment, the larger the light-receiving area, the more nutrients that orchid plants can accumulate, and the orchid seedlings will naturally be more robust.
