When is the most suitable time for Cymbidium to divide seedlings? explain the time and steps of dividing seedlings in detail.

After the propagation of Cymbidium, the seedlings need to be divided after growing seedlings. Some flower friends think that small seedlings are good, and some think that growing up points are good for survival. When is the most appropriate time for orchids to divide seedlings? is there any difference in seedling separation time between sowing and plant propagation? The seedling division after sowing and propagation was carried out when the seedling grew to 2 ~ 3 cm, and the seedling separation temperature was 15 ℃ ~ 22 ℃.

First, the time of dividing seedlings of Cymbidium 1. Dividing seedlings after sowing

The planting of Cymbidium is generally dense and the distance between plants is small. The growth of seedlings mainly depends on the nutrients given by the outside world. If the nutrients are insufficient or can not be absorbed, it will affect the growth of seedlings. However, if the seedling is divided too early, the seedling plant is fragile and the resistance is low, so it is not easy to survive. The best time to divide seedlings is when the orchid has just grown leaves and has a height of 2 to 3 centimeters. Be careful not to hurt the seedlings.

2. Ramets and seedlings

The mode of propagation of Cymbidium includes ramet, ramet, that is, seedling. The ramets and seedlings of Cymbidium can be carried out all the year round, the Yangtze River basin in the south can be warmed up earlier, the temperature can be carried out when the temperature is 15 ℃ ~ 22 ℃, and in autumn, when the fruit is ripe. The spring seedling in the north is later than that in the south, and the seedling in autumn is earlier than that in the south.

Second, the preparation of Cymbidium before seedling division 1. Prepare the flowerpot and soil

The flowerpots used by gentleman orchids should be breathable, generally not porcelain pots and pottery pots, but tile pots. Soil should be exposed to disinfection in the sun first, humus soil or humus leaf soil can be used to add coarse sand or perlite, must be disinfected in advance to prevent the root of the plant from being infected with bacteria.

2. Charcoal powder and cutters

The root of the plant will be more or less hurt when the seedling is divided, especially when the seedling is divided, the wound can be coated with charcoal powder to absorb moisture and return to the root to rot; if it is a seedling after sowing, it does not need a knife, if it is a split seedling, if the root can not be broken, it should be cut with a knife.

Third, the steps of dividing seedlings of Cymbidium.

We know when it is most appropriate to divide the seedlings, and prepare the materials and tools needed for the seedlings. The next step is to start to divide the seedlings. Sowing and reproducing seedlings is relatively simple, just transplant the seedlings with soil directly. Here are the main methods of operation of individual plants and seedlings.

1. Gently pull the mother plant out of the basin, find the plantlet to be divided, and slowly separate its root from the root whisker of the mother plant. The root of a gentleman orchid raises a leaf, which can be directly broken off, and the root system is relatively large, which can be cut with a knife.

2. Apply charcoal powder or soot to the separated wound to prevent the wound from damp and fester, put it in a cool place and dry slightly to heal the wound.

3. Planting the plant, not too deep, the soil can buy the root of the plant, the surface is covered with a layer of sterilized sand, watered and moisturized, the wound grows completely in about 2 weeks, the plant recovers, and then covered with a thin layer of soil, it can survive and grow new roots in 1 ~ 2 months.
