The reason why the butterfly orchid bud fell

There are many reasons for the abnormal drop of butterfly orchid bud, so in many aspects of cultivation and management, flower friends need to pay enough attention. Let's take a look at the specific circumstances that will make the bud fall.

Analysis on the causes of bud falling

The temperature difference between day and night is too large

If the temperature difference between day and night is too large, the plant can not adapt to the sudden change of temperature condition, which will lead to bud drop.

Insect pests such as mites

In general, the bud will suddenly become dehydrated, the color will also become abnormal dark red, when the insect pest is serious, it will make the bud all fall.

Root system damage

Improper application of water and fertilizer will make the root growth abnormal, if the root keeps anoxic state for a long time, it is difficult to provide sufficient nutrients, resulting in bud loss.

Environmental pollution

After the air is polluted, the harmful substances in it enter into the tissue of the bud because of the action of osmotic pressure. At this time, the injured bud will be plucked away, and small water droplets can be seen inside; most of the contaminated buds are yellowish brown, black in severe cases, and will become moldy and fall.

Insufficient photosynthesis

If you do not receive sufficient light during the day, the respiration will increase at night, which will make the supply of nutrients in the plant fall short of the demand, so it is difficult to maintain the normal bud growth.

Poor ventilation in greenhouse

If the indoor air is not ventilated in time, it will be difficult to provide Phalaenopsis with sufficient fresh carbon dioxide for photosynthesis, which will also lead to insufficient yield of nutrients.

The temperature is on the high side day and night.

That is, the temperature is higher than 29 ℃ in the daytime and 20 ℃ at night, which will accelerate the metabolism of the plant and cause excessive loss of nutrients, which is easy to yellowing the flower bracts, and serious ones will fall.

Medium is too wet

If the medium is too wet during flowering, it will greatly reduce the oxygen content in the root system and adversely affect the normal development of flower buds.

The air relative humidity is too low.

The humidity of the air can not reach the conditions needed for the normal growth of Phalaenopsis, which will make the pollen grains in the flowers fall off.

Mechanical damage

In the modeling pruning of Phalaenopsis, if the interior of the pedicel is accidentally injured, it will affect the normal supply of nutrients. Or when the root system is accidentally broken on the pot, the normal nutrition supply of the plant will also be affected.

Use of hormonal drugs

If hormone drugs such as buds and dwarfs are sprayed in the flowering and seedling stages of Phalaenopsis, it is also easy to make the plant bud drop.
