What is the reason for the short stem of the small rosette orchid .

First of all, the principle of phototropism in plants should be understood. The phenomenon of growth bending caused by unidirectional light irradiation of plant growth organs is called phototropism. The phototaxis mentioned by Junzi Guolanyou mainly refers to the positive phototaxis of the stems and leaves of the aboveground parts of plants.

Dutch scientist Winter believes that the phototropism of plants is due to the transport of auxin from the top to the backlit side under light, and the auxin concentration on the backlit side is higher than that on the phototropic side, which makes the dorsal side grow faster and causes the stems and leaves to bend towards the light.

It can be seen that the stronger the light, the less auxin, and the slower the plant growth; The weaker the light, the more auxin and the faster the plant grows! (For example, when the light is strong, the flower stem of daffodils is short, and when the light is weak, the flower stem is long, and some orchids take bagging measures for the height of the flower stem of the orchid is also the application of this principle) Under strong light, the auxin distribution difference between the light side and the backlight side is small, and the growth is slow, showing weak phototropism; Under low light, auxin is more, the plant grows fast, and the auxin distribution on the light side and the backlight side is different, showing strong phototropism and getting more sunlight, which is an adaptation of plants to the low light environment!

The time of each flowering time of small peach is comparable to that of other Jianlan, it is characterized by easy flowering, and it can bloom after a year.

Two or three times, not each time the flowering time is long.

Flowers bloom for too long and consume nutrients, which hinders budding and leaf growth and flowering the following year. The flowers of Chunlan bloom for about half a month, and the flowers should be cut off in time after the bloom fails. Whelan's flowers, when the last flower of the inflorescence opens l week, the inflorescence is cut off.

When breaking the flower leaf, stabilize the leaf base with one hand, and press the flower leaf to one side with the other hand, which can be broken and pulled out from the base, or it can be cut off.

Watering orchids are terrestrial plants that love moisture and waterlogging. Many beginners, fearing that they would lack water, ended up watering too much water and rotting the fleshy roots of the orchid. The watering principle of soil orchids is "rather dry than wet", as long as the orchid soil is kept a little moist.

For soilless orchids, the opposite is "better to be wet than dry".

Orchids do not have high requirements for moisture, and should be dry rather than wet. In January and February, water once a week; In March and April, water is delivered every 3 4 days; In May, water every 2 days; In June, water once a day; In July and August, water every 3 days; 9 December, gradually reduce from watering twice a day to once a week, and be careful not to get caught in the rain.

For an orchid, its quality is directly related to the height of the flower arrow, the flower arrow is not tall, even if it blooms, it will be blocked by the leaves of the orchid, and it will not be called the shelf, it will lose its original charm, and the ornamental value will be greatly reduced. If the flower arrow grows higher than the leaves of the orchid, it is called out of the shelf, and it is considered a superior orchid.

According to the description of flower friends, last year, the flower arrows were still growing very well, which can basically rule out the reason for the orchid variety. Therefore, if you want to find the reason, you need to start from the maintenance conditions. At the root of the problem, the reasons for the short arrows of orchids are generally as follows.

Insufficient nutrients before flowering, orchids are generally applied with diluted thin liquid fertilizer twice a month. It is recommended to use special orchid fertilizer.

Undernutrition. Orchid in the bud period, need sufficient nutrition, to ensure that it has sufficient nutrient supply, if in its bud period, flower friends ignore the nutrient supplement, orchid may be undernourished, will cause the orchid arrow height is insufficient, too short, hidden in the leaves, not out of the shelf.

Orchid flower arrows are emaciated.

is a lack of nutrients.

It would be nice to fertilize more.

You can add some fungicide to the soil and then apply fertilizer after a few days.

Come back to me inadequate. Or it's not good to be too thin during the growth process.

Orchid flowers are weak, mainly due to lack of nutrients, and it is good to put on some fertilizer suitable for orchid flowers.

I think it may be that there is a lack of nutrients in the soil, so you can apply some fertilizer.

What is the reason why the orchids are getting thinner and thinner.

The small pink orchid is relatively wild, reproduces quickly, and has strong adaptability. Therefore, it is better to grow than other similar orchids, usually placed indoors in a sunny and ventilated place, and moved outside for an hour a week to bask in the morning or evening sun. After 1-2 months of proper loosening of potting soil, you can now bury 30 grains of compound fertilizer into the side of the pot.

Usually watering to see that the topsoil is whitish or cracked before watering, and there is a sense of dampness without watering.

There are many reasons for the short flower stem: such as weak seedlings and poor nutrition, flower stem or flower injury (hard injury or insect injury), disease, plant dehydration, etc., will cause the flower stem to be short. Your "flower stalk is very short and small", I guess it is because the seedlings are weak, and you are malnourished.

It is recommended to turn the pot and change the soil in the spring.

The whole lake turned red (it was blood), and a hand was stretched out from the lake, and the girl's feet were grabbed, and she was pulled into the lake, and then, 100 kilometers away from the forest, the girl's body and clothes were found, but her head was missing, and the people opened her backpack and were frightened, and the bag was her head, and her expression was very painful, and the people who found her had abandoned her body in the forest, and then left, and since then, no one has dared to go to that forest.
