Propagation method of rabbit ear orchid

Ramet propagation

The best breeding season is spring and autumn, and it is suitable to separate once every three years. Plants with strong and dense pseudobulbs shall be selected for ramet, and at least every five pseudobulbs shall be connected together after ramet. Reduce watering before operation to ensure that the soil in the basin is dry

When placing the pot, the bottom of the pot shall be covered with a layer of broken tiles, and then a layer of coarse stones, about 1 / 5 or 1 / 4 of the depth of the pot, and then coarse-grained soil and a small amount of fine soil shall be added. Finally, the plant shall be cultivated separately with sandy soil rich in humus. The depth is that the pseudobulb has just sunk into the soil. The surface is covered with fine stones or Yuncao, and then watered. Place in a cool place for 10-15 days and keep the soil moist

Sowing and propagation

The seeds of Rabdosia are very small, the embryos in the seeds are not fully developed, and the germination rate and survival rate are very low. Moreover, the ability of seed skin to absorb water is poor, and the general method often can not germinate. It is necessary to use artificial culture medium and orchid fungus to complete the supply of nutrients and germinate

It is suggested to select uncracked rabbit tailed orchid fruit, disinfect the surface with alcohol and take out the seeds. Then soak the seeds in 10% sodium hypochlorite for 5-10 minutes, and then rinse them with sterile water for three times. The temperature is 25 ℃. After germination, it can grow into protocorms under light. The whole process takes about half a year to a year

Precautions for propagation of orchid

Ecological habits

Rabbit ear orchid likes Yin and humidity. Avoid direct sunlight and dryness. The suitable growth temperature is 15 ℃ to 30 ℃, below 5 ℃ will freeze, and above 35 ℃ is not conducive to growth

Diseases and insect pests

Tulip is infected with white silk disease in plum rain season, which will lead to rhizome rot. At this time, it is necessary to get rid of the accompanying bacteria in the soil, sprinkle lime, and then place it in a ventilated place

Secondly, anthrax will surround the rabbit ear orchid all year round, and the disease spots appear as dry black spots, which will seriously lead to the death of the whole plant. In this case, you can choose to spray wettable powder once a week or so, such as methyltobuzin, and then spray Bordeaux solution once in 15 days or so, and spray it three to five times in a row, you can see a good effect

Finally, pay attention to the prevention and control of scale insects. Once found, measures must be taken immediately. The fastest way is to remove them manually or spray them with Omethoate EC. The concentration of mixed water is 1500 times< span>
