Relationship between Orchid Seedling rate and Orchid pathological changes

Introduction: which orchid friends do not want their own orchid seedlings, strong seedlings? First of all, let's talk about my own orchid planting process. In the first two or three years of planting orchids, I copied orchids with little knowledge and never died. At that time, I once sighed, "who says orchids are not good?" With the accumulation of orchid experience, not satisfied with the status quo, disrelish their own orchid seedling rate is low, orchid is not high enough, change planting materials, fertilization, ah, everything to a few times, began to die orchid. Later, due to job transfer, for three years, rarely in the location of the orchid, the management of the orchid is mostly I called to guide my lover to operate, but the orchid grew very well in those years, rarely dead orchid. There is also an old orchid friend who planted orchid on his own platform for 7 or 8 years, and the orchid was very good. Later, he moved the orchid to the "modern" new orchid room built on the roof, and he always died of the orchid, but in desperation, the old orchid friend moved the orchid to the original platform to keep the orchid alive. Is it strange? It's worth reflecting on.

Humidity

Lanyou all know that if the humidity is high, the seedling rate is high, and the new grass grows fast. how can the platform without a humidifier improve the humidity? it can be increased by more watering.

Deep planting and shallow planting: deep planting can improve the humidity of Reed head and increase the seedling rate, poor ventilation or water watering is easy to rot new buds, so it is only in ventilated places that it is dry and wet when watering, that is to say, it can only be watered when it is dry. Platform orchids are generally more deeply planted. The place with general ventilation can be planted shallowly, if the humidity is guaranteed, the orchid chamber with humidifier can be planted shallowly, the watering frequency of shallow planting can be high, and the orchid field generally adopts shallow planting.

Diseases and insect pests

Dry cultivation of diseases and insect pests will be less, but the growth of orchids will be inhibited, we all know that water is the source of life, more water, bacteria will be active, that is to say, easy to get sick and easy to die and rot.

Insecticidal and sterilization: bacteria generally invade from the wound of orchid, how is the wound produced? There are mechanical wounds, such as seedling separation and transportation, such as those caused by strong winds and people touching orchid plants that cause friction between Reed heads and plants. What should be mentioned here is the wound bitten by pests. I think there are snails, red spiders, nematodes, thrips and so on. I think many rotten buds are caused by snails and red spiders, so it is necessary to kill insects and sterilize regularly.

When the humidity is high, the wound heals slowly, and the chance of getting sick is great, so the mildew season is prone to second rot, especially soft rot, that is, dead new sprouts and dead new grass. in order to reduce the occurrence of diseases, we can use dry and wet and more ventilation to speed up wound healing; pests and germs have the habit of overwintering, we had better not use old plant materials when turning pots, and we should also clean Langen and basin utensils to reduce the introduction of disease sources.

How to choose the relationship between the seedling rate and the dead orchid should be grasped in practice. (some views are not necessarily
