What to do with the Arrow in the Orchid? the reason and solution of the Arrow in the Orchid

What about the arrow in the gentleman's orchid? The so-called clip arrow means that when the flower arrow of the gentleman orchid does not grow well, but is caught by the leaves or branches in the middle, the fire blossoms. Generally speaking, this kind of words will not bloom for a very long time, but will wither in a short time and form rotten flowers. This will cause the orchid to become very ugly, and the blossom is not so beautiful. Let's take a look at the reasons and solutions.

What about the arrow in the gentleman's orchid?

The reason for clamping the arrow:

1. The temperature is too low: the extraction temperature of Cymbidium is about 20 ℃. If the temperature is lower than 15 ℃ for a long time, it is difficult to grow.

2. Lack of nutrition: there is a great demand for phosphorus and potash fertilizer during bud gestation and flowering. If it is lacking, it will make the orchid lack of trapping power, resulting in the phenomenon of arrow entrapment.

3. Hypoxia in the basin soil: the oxygen demand of the root system of Cymbidium is large during the budding period. if the basin soil is too fine or in a state of high humidity for a long time, it will reduce the basin soil permeability, resulting in hypoxia, resulting in the phenomenon of arrow entrapment.

4. Constant temperature cultivation: the flowering of Cymbidium requires a day-night temperature difference of 5 ℃ to 8 ℃. If the plant is kept at the same temperature during the day and night, it will affect the nutrition accumulation of the orchid, and it is easy to clip arrows during flowering.

5. Root injury and rotting: if the root system of Cymbidium is damaged or rotten, the nutrient absorption pipeline will be blocked and the plant will blossom.

6. Bad varieties: some varieties of orchids are born with arrows.

Prevention and control measures:

1. Adjust the temperature and increase the temperature difference: in winter, after 20 days of low temperature treatment, the plants were timely placed under the normal temperature, and the temperature difference between day and night was kept at 5 ℃ to 8 ℃ as far as possible.

2. Increase the application of phosphorus and potassium fertilizer to ensure nutrition: in autumn and winter, properly increase the application of phosphorus and potassium fertilizer to promote plant flower formation and flowering.

3. To ensure an appropriate amount of water supply: during the pumping period, ensure that the water content of the basin soil is between 30% and 50%.

4, the combination of medicine and medicine to promote the flower: the arrow promoter purchased in the market can be smeared on the flower tree or dripped in the pot soil according to the instructions; the leaves on both sides of the arrow can also be stretched out artificially, but the leaves can not be damaged, so as to reduce the pinch force of the leaf to the flower flower and promote the flower flower to protrude and grow as soon as possible.

5. Change the soil again, dry first and then wet. Note that the soil should not be watered within 5 days after the soil change, and the soil should not be dry, but should keep about 30% moisture; water should be watered once after 5 days, so that it can generally blossom.
