How to keep the balcony orchid as small as possible

Author: watching chess

The reason for the focal tip of orchid is very complicated, and it is impossible for me to understand it in a comprehensive way. Some fragmented ideas can provide some reference and a way of thinking for Orchid, which is not a waste of thought.

First: the reasons of environment and climate.

Air pollution in big cities is becoming more and more serious, automobile exhaust and coal burning will produce SO2,SO2, on the one hand, it will form acid rain, on the other hand, SO2 in the air will directly harm the orchid.

Because of the long-term haze weather in some cities, the air is humid and dusty, and orchid leaves are more likely to breed germs.

Rizhao is a small city, and the air quality is excellent most of the time, which provides the most basic environment for growing orchids.

Second: the reason of the variety.

Varieties with taller plant types are more likely to focus, which may be related to the distance of water transport in the plant.

Traditional old species are more likely to focus, which may be related to the presence of toxins in the body after a long period of artificial breeding. The varieties that go down the mountain are generally not easy to scorch.

A new variety of vegetarian heart, generally not easy to focus.

Third: the reason for watering.

Family orchids are generally irrigated with tap water. the water quality of an area is very important, and the weakly acidic water quality is more likely to wash away the dust from the orchid leaves, which is conducive to the growth of orchids.

The method of watering is also related. On the one hand, heavy water spraying can keep the orchid leaves clean, on the other hand, it can wash away the excess nutrients in the plant material, and the watering process can also make the orchid leaves absorb enough water and seal the tip more easily.

Granule plant nourish orchid, rather wet than dry, once the orchid leaves lose water due to drying, it will cause irreversible coke tip.

Fourth: the reason of fertilization.

Fresh orchids are more likely to be capped and fertilized too thickly. once they cause fertilizer damage, they will inevitably hurt the orchid leaves.

Orchids need to grow strong, grow more seedlings, and not focus well, which in itself is a pair of contradictions. How to apply fertilizer reasonably is very important. In the future, I will talk about how I apply fertilizer separately. In a word, thin fertilizer is applied diligently.

Fifth: the reason of light.

Orchids cultivated by strong light have thick leaves, short leaves, good leaf transpiration and easier tip capping. Some orchids will have different opinions on this point.

Yin culture may be easier to produce fully sealed seedlings, but the stress resistance of such seedlings will be much worse.

Sixth: the cause of ventilation.

Ventilation means that the air can convect, but the strong wind is not good. The function of the electric fan is to let the orchid leaves dry as soon as possible after watering. This is different from ventilation. The best way is to let the air flow naturally.

The family raises orchids, the north and south are transparent, and the window ventilation is enough.

Seventh: the cause of temperature difference.

The temperature difference is big, the orchid leaf is thick, short, the Lutou is big, it is easier to seal the tip.

Eighth: the cause of humidity.

It is generally believed that high humidity is beneficial to the growth of orchids, but in fact, it is not always the case. The environmental humidity of the greenhouse is high, which is generally accompanied by fungicides.

Family raise orchids, I do not sterilize, high humidity is more likely to breed germs, natural ventilation, humidity determined by the environment.

Ninth: the cause of insect pests.

The main pests of orchid leaves caused by family orchid cultivation are red spiders, thrips, scale insects and so on. These pests are very contagious, and the first two have caused irreversible damage to orchids once found.

In the season of bud opening, preventive injection of Huakang insecticide is necessary.
