Look at the cultivation of Orchid Root-- repost [the Capital of Chunlan]

A good Langan can be divided into four situations:

1. Langen white, crystal head, the right length (according to some orchid books, the appropriate length of the orchid leaf length of about 80%), uniform thickness, the old orchid root can produce new roots. This kind of orchid root is the best, which shows that the planting material is suitable and the cultivation method is good.

2. Langen white, crystal head, uniform thickness, but Langen is long and thin, mostly because of dry or less fertilizer, later can be a little more water or fertilizer.

3. Langen white, crystal head, uniform thickness, but Langen short and thick, mostly because of wet or fat, later can be slightly dry or less fat.

4. Langen is white, with crystal head and suitable length, but the thickness of the same orchid root is uneven, mostly because it is dry or less fat in one period, and wet or fat in another period, which can be neutralized and consistent in management later.

Yellow root disease, black root rot, bad Langen is generally yellow and black, there is no crystal head or crystal head is not obvious, can also be divided into four cases:

1. The orchid root is yellow, indicating that it has been injured by germs, medicine, muggy steam, freezing and so on. Pay attention to sterilization, ventilation, cooling, antifreeze, use low concentration drugs, water thoroughly, not at high temperature.

2. Langen black, there are various forms of expression, there are whole root black; there are outer white inside black; there are outer white inside black; there is a layer of black in the middle of outer white; there is a section of blue root black; there is head black, and so on. Langen blackening is mostly caused by the impermeability of the plant material. Leach, too much water, fat weight is mainly caused by fat weight, after the choice of leached water breathable plant materials, less water, less fertilizer or fertilizer-free.

3. Langen empty, the skin is intact white, the inner layer rotten empty, mostly caused by long-term water shortage, do not lack water for a long time in the future. The old root has empty root or a section of empty root, which may be the reason why Langen did not touch the planting material.

4. Langen white, some of which are dead and bad, may be germs. For the causes of disease and insect damage, attention should be paid to sterilization and insecticidal in the future.
