In spring and autumn can be carried out, generally every three years a plant. Any plant with strong growth and dense pseudo corms can be divided, and at least 5 connected pseudo corms should be stored in each cluster after division. Before planting, reduce irrigation water, so that the basin soil is more than. After planting, cover the bottom hole of the pot with broken tiles, then lay coarse stones, which account for 1/5 to 1/4 of the depth of the pot, then put coarse-grained soil and a small amount of fine soil, and then plant with sandy loam rich in humus. Planting depth to the false corm just buried in the soil strength, basin edge to leave 2 cm along the mouth, spread Cui Yun grass or fine stones, finally pouring permeable, shady place for 10-15 days, keep the soil moist, gradually reduce watering, normal maintenance.

Jewel Orchid Seed propagation

The seed of Jewel Orchid is very thin, and there is only one incomplete embryo in the seed, so its germinating ability is very low. Besides, the seed coat is not easy to absorb water, so it cannot germinate by conventional sowing methods. Therefore, Jewel Orchid fungus or artificial medium is needed to supply nutrients for germination. Planting fruit had better choose not cracking, surface with 75% alcohol after sterilization, remove the seeds, soaking with 10% sodium hypochlorite for 5-10 minutes, take out three times with sterile water rinse again can play in the cultivation of the bottle containing medium, and dark in the pure, the temperature about 25 c, stirring and then moved to the light that can form the original bulb.

Disease control

Damping off

It is mainly caused by Fusarium. The yellow brown water spots appear at the base of the stem of the sick Jewel Orchid seedlings, which quickly develop to a circle around the stem, and the tissue of the sick department rots, dries up and shrinks in a linear form. The rapid development of the disease, rapid seedling collapse death, cataplexy phenomenon.

Soft rot

③ Little ground tiger

The third instar larva ate the heart leaves and leaves of Jewel Orchid in a small groove or mesh shape, and the third instar larva bit off the young stem of Jewel Orchid near the ground, resulting in ridges of missing seedlings.

(4) Mole

The root and stem of the seedlings are eaten in the soil, and the head is broken in a tangled shape, causing the seedlings to die, and the soil surface channeling into many uplift tunnels, so that the roots of the seedlings and soil separation, water loss and death.
