Propagation methods of Orchid

Orchids are commonly used in plant division, seeding and tissue culture. Common to plant propagation mainly, orchid plant orchid spring and autumn can be carried out, orchid plant generally every 2-3 years.

At least five false bulbs linked together should be preserved in each clump after splitting, and at least three leaves on these false bulbs should grow vigorously. Before dividing plants, irrigation should be reduced to make the pot soil drier. Remove the old soil from the roots, wash with clean water and air for 2-3 hours. After the roots are whitened and wilted, the plants are cut between the stems of the pseudobulbs with a sharp knife, and the cut is coated with plant ash or sulfur powder for preservation.

Orchids are grown on sandy loam soil rich in humus. The flowerpot is good with earthen pot, advantageous plant grows. The drainage hole of the bottom of the pot should be larger than that of the general flower pot, and it is appropriate to have 3-4 bottom holes. The size and depth of the flower pot depend on the size of the plant.

When putting on the pot, first cover the hole of the basin bottom with broken tiles, then spread coarse stones, accounting for about 1/5-1/4 of the depth of the pot, and then put coarse soil and a small amount of fine soil, so that the soil in the middle of the pot rises and then planted. When planting, spread the roots and tilt the plant slightly. Unroll the roots as you fill the pot and shake the pot several times while pressing it with your fingers.

The planting depth is such that the false bulbs are just buried in the soil. After planting, the pot surface is slightly arched, and the edge of the pot is reserved for 2 cm along the mouth. Finally, spray 2-3 times with a fine spray pot, and place in the shade for 10-15 days. When epiphytic orchids need to be divided, repair the roots first, cut them properly, then wrap them outside the roots with peat moss, fern roots, residual leaves and other cultivation materials, and plant them in empty flower pots. Then water it and keep it moist.

Site selection: the requirements of the surrounding open, well-ventilated, and close to the water, humid air, no soot pollution. In the southwest of the site, evergreen broad-leaved trees can be planted with cymbidium, and the canopy density should be about 0.7, which can reduce afternoon sunlight and adjust humidity and temperature.
